I was wondering how many big fellas ride zx-10's, and also have questions and comments to make. 1st,im 265lbs and have found the bike, my "07 10" to be quite comfey for my fat ass. The problem i have found is the bike doesnt really like to accelarate, infact i have played around with amys (my girlfriend) 2003 636 in some roll-ons from 60-70 mph range and 6th gear, and its embarrasing for me to say but she pulls a bike lenght on me. She will run hers up to around 130mph or so but my bike will not go around hers, i know she ways 85 lbs less than me but i figured the 10's hp would make up the diffrence. Also im going to have a friend help me set the sag and was wondering if the stock springs can be adjusted enough for my weight or do i need to look elsewhere for stiffer springs. What are good sag #'s for street riding/back road carving.Come to think of it i think my bike boggs a little while rapidly opening the throttle like when we do roll-ons. My 10 is stock with the exception of scorpion stainless bolt-ons.

i weigh about 225 and i had to put a stiffer spring on my bike to get the sag set right....i am guessing you will as well

Hey Cott, I was just about to create a similar topic when I seen yours. I am about to trade in my 05 12r for a 10r or a 14, but I cannot decide which one yet. The 14 is supercomfy, and the ten felt really small under me, as I am 6' 2" and 240lbs. Can I see pics of big guys on there 06-07 10r's?

have your bike checked... I'm currently at about 265lbs also :headshake . But I know my bike wouldn't have any problems leaving a 600 bike behind in a straight line, no matter how light the 600 rider is.

Hey Cott10r, Nice to know I'm not the only fat ass on the 10R..haha.. (270lbs w/ gear) it's not fat..we're just big boned. I'm planning on changing the shock and doing a fork mod as soon as I run in 4K on my '07. The brakes also seem a bit weak..gonna get a new M/C, S.S. lines and pads. I'd say you should change the springs for the suspension as a minimum for safety and performance reasons. (My shock bottoms out) It will also let you use the recommended suspension settings instead tinkering too much trying to compensate for the spring rate. (I don't think it's even within range for our weight - I've tried to set it maximum and it makes my ass numb). As I haven't really run in the engine I haven't done much in terms of racing anyone. I'm probrably going to get a +2 in the rear to try it out first, although many are just opting for the 16t (-1 in front and greater acceleration) instead. There's not much harm done in trying either option out as it swaps back in easily and is relatively inexpensive. If you do go with a new sprocket you may want a speedo healer to compensate for the milage if that's important to you. Oh yeah ... I've also ordered the 1/5 from Rifleman and it's pretty damn awesome. Another inexpensive mod you may want to consider... feels faster anyway :P

yeah same here, I went +2 in the rear, that really helped

I am about 6'3 275 i have a 05 zx-10 i have no problem pulling from a 600 i also beat a couple of 1000s out there.

I'm 6'2...220 lbs Could not set the SAG up front with oem spring...had forks resprung and revalved at Chassis Dynamics, great shop.. www.motorcyclechassisdynamics.com Also, on the track, differences (Wot) between a stock liter bike(mine) and a well tuned 600 on race gas are not huge, especially if the dude on smaller bike is 50 pounds lighter.. :helmet:

My 10r out pulled my cousins 636 easy. I am 6'1" about 250lbs (with all the gear). He is 180-190. No problem here and yeah, the bike is actually confortable. It actually feels better to me than my 2002 Suzuki Katana I had before.

What I meant is that I pass easily 600 and 750's on the banking at Fontana but it's another story on a tight track like Streets of Willow or Pahrump. :rolleyes:

have your bike checked... I'm currently at about 265lbs also :headshake . But I know my bike wouldn't have any problems leaving a 600 bike behind in a straight line, no matter how light the 600 rider is. I agree with 2wheeler: I am about 265 with gear and I have no problem leaving 600s, as well. Now, I also realize that the first peak of torque for a stock ZX10 is at about 5500 rpm. I don't think you are quite to that rpm which might have something to do with the jump she is getting on the roll-on. Try a roll-on with your rpms 5500-6000 rpm and see what happens. How does your bike do in first? Is the front end light or actually rising to a smooth wheelie under full throttle? Snap into 2nd and does it do the same? Of course I do realize that when you hit 2nd, you will be doing triple digits, so you may not want to do that one...:badteeth: ...The brakes also seem a bit weak... How much brake do you need? If you are not racing, you shouldn't have any fade...I actually have to be careful not to do a stoppie if I get a little overzealous with my braking...???? ...My shock bottoms out... Another instance that I have not experienced. It is my understanding that the springs on the 06-07 is a variable rate spring? Can anyone confirm? Supposedly they are using the same idea as the variable load car spring where a portion of the spring is using for light weights and the heavier the load, the more of the spring that will start reacting? ...you may want a speedo healer to compensate for the milage... Just to be sure...did you mean to compensate for the miles per hour and not mileage? I think the stock odometer shows correct mileage but the speedo is "optimized", whatever that means :dontknow: , but when you speedo heal it, the speedo reads correctly and your odometer will actually show LESS miles traveled because of the way Kawisaki built the darn thing. As with all my other posts, I welcome corrections, criticisms, and questions. :mrgreen:

Lightweights. 6'6" @ 275 lbs before gear. :) I have no problem keeping up or ahead of others. I would play with your rear suspension and get a double bubble screen. That will help deflect the air around you.

I am 6'0" at 248lbs and have no problem on the 10R. I leave slighly modded 600s fairly easy, they stay with me a second on take off cause they can leave a little harder without standin up as easy but once I hit second its holla at ya later. A friend of mine has a 06 Gix 1000 and I pull on him fairly well considering he weighs about 25lbs less. I weighed 285 at the beginning of this year and I cant really feel much difference on how the bike pulls now compared to then. I havent done any suspension work as of yet.

6'6" 255............I think the 10 is comfy in small doses. After about a couple of hours my legs start to get a little sore but I have never had any problems as far as hanging with other smaller bikes. I have put new springs in every bike I have ever owned except this one. It has handled my extra mass very well, but I think I am going to spring for some new springs and get the suspension sorted properly. And no I do not have any pics of me on my bike, you creep.........:heyyou:

Lightweights. 6'6" @ 275 lbs before gear. :) I have no problem keeping up or ahead of others. I would play with your rear suspension and get a double bubble screen. That will help deflect the air around you. LIGHTWEIGHTS HA!! I am 602-603 295lbs. i pulled on my buddies 916 Duc down in daytona it was fun. i am 10" over and lowered, regeared, and have no trouble what so ever pulling out in front of people. long trips do kind of suck. the rearsets set pretty high for us long legged folks. after about a hour and a half i need to stop and stretch cause i start to cramp.

i'm 5'11" 245 - 250lbs. last xmas i took my sister in law for a ride and she's about 265lb big girl. i was impressed with how the bike hauled our fat ass all around phoenix with no problem. we top 145mph more than 3 or 4 times and the bike was still climbing the speedo. and my bike was all stock at that time. I LOVE MY ZX10R :thumbsup: ..................................

I LOVE MY ZX10R :thumbsup: .................................. Isn't the load limit of the 10R 390 lbs?!? Anyway, I'm 6'3" and 290 lbs and my bike pulls pretty hard at all rpm. I haven't done a thing to the suspension and it rides much better than my 600rr did. I'll try to get a pic of me on the bike.....

im 6'5 1/2 and 268 and i bought a 06 r1 because of the comfort compared to the 10 which i orignally wanted. well i had enough issues with the r1 after 1800 miles that i went an bought a 06 left over 10r anyway. it wasn't as uncomfortable as i had imagned. After reading on here and about vortex rearsets and how you can switch the brackets to make your pegs go lower and back made my new 10 that much better. That was deffinatly the best money i ever spent and the comfort lever is incredible. as far as power i never had any problem with passing anyone or having my bikes feel like they were dogs. Also i never needed to change the rear spring. I only use my bike for street riding not the track.

Grease: re: Brake - I've had instances where I have had to pull the lever all the way back, almost getting into an accident. (My area has lots of mountain terrain and rides are very long 9 hours avg - continuous, so the braking is heavy) I also plan on doing some track days in Zhou Hai - I agree this isn't a necessary mod for everyone. re: Bottoming out - Maybe I phrased it wrong.. I have my shock on the stiffest setting and my preload is correct.. On some bumpy areas where I ride the bottom of the faring actually hits and gets scratched (Not often). My old bike with correct springs never did this. re: MPH, I haven't put one on the 10R yet..so it's good your brought it up. (So only speedometer is incorrect?) I didn't realize that. On my other bike and both mileage and speed went up. I personally feel a lot more confident with the springs changed and I would recommend it to heavier guys. The brakes ARE not neccessary (Just something I plan to do). The rearsets seem like a great idea too, but I will live with the OEM for now...low on funds

Grease: re: Brake - Maybe it's my riding, but I've had instances where I have had to pull the lever all the way back almost getting into an accident. I also do some track days.. (Just my personal experience) re: Bottoming out - Maybe I phrased it wrong.. I have my shock on the stiffest setting and my preload is correct.

With the old bike and correct springs this never happened. re: MPH, I haven't put one on the 10R yet..so it's good your brought it up. I didn't realize that only the speed went up and mileage didn't. Maybe I'll save the money on the healer then. Had a healer on my other bike and both milage and speed went up. Brake: Yesterday I had a lady run a light after it was red for her more than 5 seconds and I had to grip it! I heard some chirping and rear end got light (in the air), so I know my brakes be workin'! :pale: Bottoming out: I am 5'10 and 265 and I have hit some serious road bumps...never bottomed out. Although it does sit lower than my old ZX7, never scraped...I also did have a guy about my size sit on the bike in the shop before I bought it and they setup the suspension before I ever picked it up...I wish I knew how mine was setup, maybe I could offer more assistance on this. :dontknow: Speedo Healer: Kawasaki's speedo and odometer is fed from the same signal, so when you bring the speed down to it's correct number, it also slows the odometer. On your bike, that means that your odometer was running fast! The only one that I know of that doesn't, if I remember correctly, is like the FJR1300 because the odometer and speedo are given separate signals, so when you "heal" the speedo, the odometer is unchanged. Here is the link to speedohealer.com's FAQs that explain a little more/better than I... SpeedoHealer-FAQ (http://www.speedohealer.com/eng/faq.htm)

I ride with a few guys down here in so cal with liter bikes and they are not faster than me (6'0 260lbs). My buddy has the same 06 10r as I do same mods everything but he is like 5'5 180 and he is not faster than me. I leave harder than he does off the line too. it might just be you. BUT my 10 did have an exhaust vavle issue the dealership had to correct and its a lot faster now

I am 5'11 and 220 and i have not problems keeping up up with the other 1000's and beating most...

Grease: Thanks for the clarification - that how I thought it worked :P - My written english is probrably quite bad as I hardly use it anymore, hence the misunderstanding.

I used to feel the same as you do as far as not being powerful enough. My buddies 06 gsxr1k would demolish me during roll ons when I first got the bike. One of my buddies jumped on my bike, hes maybe 20 lbs lighter then me (I'm 6'4 290) and beat the gsxr. They ran again and the same result. He told me I was being a pantywaist with the throttle. Now I pretty much keep up or pass any like moded bike on the street. The only thing that really bothers me about the size of the bike in relation to my size is the high speed runs. once over 160 to much wind is hitting me because I can't tuck like a skinny guy can. Makes it hard to accelerate up to 180(indicated) because everything starts to shake.

well im 5'9 and weigh 230-235lbs

Im giving her all she's got captain, seriously though i give it hell in top gear and it wont pull away from her and i too did a roll-on with my buddies 05 10R granted he's 100lbs lighter than me but he blew my damn doors off. Maybe im wrong but a 636 should be a lite snack for a zx-10

something is off on the bike then. if its not you then something is up with the bike. only problem is unless its giving you a FI light the dealer (unless they are good) can't figure it out.

Hmmm, must be the bike. I still haven't the berries to go WOT all the way up to redline! I still chicken out at around 8000 rpm and its still accelerating waaaaaay faster than my 05 600rr did....

6'1" - 197 pounds without gear and no problems with passing other bikes ,specially 600 .When I first bought the bike I came from a zx-12 which have more low power. I found that I had to use more throttle on the 10 to get the same roll on because I was used to the 12 power. If you came from a 12 or Busa you will find out that you have to give more throttle to have the same roll on you used to. Once you get use to it you will pass others easily.

5'10" 245-250 and no problems here with power, but still haven't really opened her up yet as only have just over 1k miles and would like to change the oil one more time. Will need to dial the sup. in though for the extra weight as at times the rear feels too stiff and the front feels soft in turns. On the other hand was not to impressed with the stock brakes, so put on SS lines, new pads, synthetic fluid, and Pazzo levers, but need to try it all out (still putting bike back together from winter mods).

I'm about 6' even and 235# with gear. After break-in my 06 10R pulls "my fat ass"(quote by me from another thread) away from a stop-light from 2000 r.p.m. on up with no problem if I'm lazy. After I became familiar with the track doing a track day I was keeping up with a busa and passing everybody else,...twice per session(beginner class):cool: Give me 2 seconds and I can make a clean,safe pass of any vehicle that's going 75 m.p.h. I wonder what those car driver's think when I pass them so quickly?! :helmet:

I'm 220 lbs, and was wondering if any one knows the correct rear spring rate for my weight on my "06?

I have an 06 10R. I am 6'2 255lbs all muscle. lol, I bought the -1 for the front to help with taking off but I haven't installed it yet. This bike pulls like a mofo and can easly pull ahead of my buddies 06 636 I do bounce around in some corners, which is a little unsettling. I don't know of any shop here in Sacramento that can help with setting up the bike. What do you guys have your steering dampner set at. I think I am at 9 clicks...

im 6/4 235lbs and me and my bike have no problems beating 1000's or keeping up with busa's

This just in: Busas are fast, and are not to be trifled with over 100mph. Under 100, it's a riders race for sure, and I can see the 10R taking it. I just sold mine to get my new 10R, and although I loved my Busa, this 10R is like a razor compared to a blunt machete. I love it. I am 6'4" 230, and I am also thinking -1 in the front might be coming soon.

6'3" 245 and my 10 has never let down in a race ever

Man. I dont know what the hell is going on here then with mine. Im 265 and it is set at the stock settings. I have never been on a bike that has handled so well. I'm actually afraid to change the settings. I'm taking it up to a few track events this year. My buddy has a gixxer 1k he weighs 185 and who ever takes off first wins the race. That means if I pull off first he aint catching me.

How many miles do yuou have on the bike and what year

they're thinkin "wait till i pass you" :+1: I'm 6 even about 220...the bike never feels sluggish to me....and emergency stopping with the rear tire down isn't always easy.

i have mine set at the highest setting....................... My bike doesn't seem to want to turn in when its that high. Could be just bethough. ;)

i have no problem with it. i'm thinking about getting an aftermarket damper that is a little bit stiffer to my liking. but i still love my 10 and the way it handles...........

here's me, 6'6'', 425. 04 model though.

here's me, 6'6'', 425. 04 model though. :occasion1 :rockwoot:

Well, shiat. if it hauls your a$$ on the track then we got nothing to complain about. I'm 6'4" and 275 and have noooo problems with an 07's power. this thing is wicked and im used to a busa.

here's me, 6'6'', 425. 04 model though. HELL YEAH! now thats what i'm talking about. a big man on a bad ass bike keeping it real. :icon_rr:

There is nothing wrong with your bike. Mine is the same way. I have about 140 lbs on most of my buddies and they can blow my doors off in a ROLL ON. Now if I am using the power like I'm suppossed to and are in the right gear then they can't touch me. But like you said a Roll on, both bikes in the same gear, usually lugging the motor, they will smoke me. If you figure that on a motorcyce 8lbs = about 1hp. Then I'm giving up 17-18 hp right off the bat. Then figure that even when geared down one on the cs sprocket, the 10r is still geared higher than most pre 05 Hondas, Zuks, and Yamahas. Once I start to get the rpms up I start to close the gap on them but they usually shut em down and yell "I WON!" My friends like to do roll on's with me cause that is the only way they will beat my fat butt on my 10r.

here's me, 6'6'', 425. 04 model though. where do you live?? My local drag strip you have to have full leathers. gloves and boots

here's me, 6'6'', 425. 04 model though. Hmm, no offense, but don't you exceed the bike's load limits at 425 lbs?

Hmm, no offense, but don't you exceed the bike's load limits at 425 lbs? that dude makes the bike look tiny. Look at the guy next to him riding on that bucket. I like. Big boys need small toys to make the bitches go woot!

where do you live?? My local drag strip you have to have full leathers. gloves and boots i was thinking the same thing :dontknow:. hey, do what you gotta do :thumbsup: .

Yep, I'm probably exceeding the load limit a little, you gotta do what you gotta do. I live in southeast kansas and race at Mokan dragway. I've seen them let guys race in a long sleeve shirt before.

I'm 6'0" and weigh 225lbs and had to get my suspension modified. I went with racetech for F & R with gold valves. Big big difference in riding now. That was the best $$ spent on my bike. Too bad the dealerships don't setup your suspension for your weight when you buy from them. I don't have any problems beating 600cc and some other 1000cc bikes on my 07' 10r but those Gixxer 1K just kill me. :dontknow: I may change out my sprockets according to what some say here, 16T for the front. Give it a try when my chain needs changing.

Go to racetech.com and they have a spring calculator for you

Im giving her all she's got captain, seriously though i give it hell in top gear and it wont pull away from her and i too did a roll-on with my buddies 05 10R granted he's 100lbs lighter than me but he blew my damn doors off. Maybe im wrong but a 636 should be a lite snack for a zx-10 Well no shit... start off in the right gear and see what happens... Or a much higher roll....

Like I said my buddies always want to do roll ons with me in 6th gear at like 50-60 mph. They have cbr 929 and 954 and older R1's. I tell them OK but we have to do a roll on in 1st starting at 90mph. They all cry "our bikes won't even do 90 in first gear!" I say "Well, I guess I win then don't I?"

Ya all bikes are geared so different... that means nothing about a bikes power or potential... If your gonna race, race from the right gear

Need some advice on who to talk to, to get the right replacement springs for my fork and shock for a 270 # rider.

have your bike checked... I'm currently at about 265lbs also :headshake . But I know my bike wouldn't have any problems leaving a 600 bike behind in a straight line, no matter how light the 600 rider is. I'm 260ish with gear and I had no problems running around an 06 gsxr 600 and a 06 cbr600 both with guys on them a whole lot lighter than me. GET OUT OF MY WAY!!.. :lol:

I think it is your bike. I have no probs. leaving a 600 and I am 268lbs. I even took out an 06 1000rr that my buddy rides and he is 170lbs soaking wet

I think it is your bike. I have no probs. leaving a 600 and I am 268lbs. I even took out an 06 1000rr that my buddy rides and he is 170lbs soaking wet I know its not my bike its my weight,also i came to the conclusion that my old lady was cheating by being a gear or two down (my friend saw her up shifting on another roll-on we did) i dont care who you are if your 250-300lbs running against a person who is on equal machinery and weighs alot less you are not going to hang in straight line performance,in my case i was running against a 636 with my old lady on it and she weighs 60-70lbs less than me and running a gear or two down that i didnt know about @ the time but we did it again (i pulled on her left side to make sure she didnt downshift) and left her for dead. However if youve seen my topic about racing an 01 gsxr 1000 in the racing section you'll see my point about the weight diff in riders,my friend with the 01 weights 100lbs less than me and @ any gear any speed combo he will leave me for dead while my friend with the 05 zx-10 can stay with him (he weights identical ) so

easy buddy. Don't have to jump all over me, just trying to help a little

When stripping my CBR of its road gear ready for the race track, I was told every Kg is equal to 1 HP. As in, every Kg I shed from the bike was like a 1Hp gain in power. At 265 pounds, you are 120Kg Your lady is 85 pounds less then you, 85 pounds equals 38.6Kg All things being equal, your 10 is nearly 40Hp down due to the extra weight it is carrying. That would mean an effective 130hp at the crank, which is still more than a 600 can muster. Perhaps it's time to try 16 tooth front sprocket, and maybe a 1/5 turn throttle adapter from Riffleman (both cheap jobs). Doing your shocks will stop the bike squatting as you power on, and will give you more initial thrust too - but is a more expensive job.

easy buddy. Don't have to jump all over me, just trying to help a little ah hell man i was just throwing down the information i had gathered,i wasnt jumping on anybody.

ah hell man i was just throwing down the information i had gathered,i wasnt jumping on anybody. Hey, we are all on here for a peaceful good time...I think you should calm down, and stop attacking people. :lol: :occasion1

They all cry "our bikes won't even do 90 in first gear!" I say "Well, I guess I win then don't I?" :icon_rr: i like that suggestion..................

I'm 425 pounds and in roll ons with any of the 600's I'll eat em up, I pull on my buddy with the tl1000r also. Hell, from a dead stop I've beaten a 1000rr, of course that guy just couldnt ride, he ran an 11.86 on an 04 rr. My bike dyno'd 165 at the rear wheel.
