Ok I have been slowly but surely changing my oem hardware on my 2012 10r and my aim is to get this bike as skinny as I can and money that I can throw at it to make this happen,quick run down my bike has full Ohlins,ARGp2r and 200mm can,shorai batt,Brembo fronts you get the picture!last time it was on the scales it came in at 180 kg with nearly a full tank and sorry Dymag CF rims,since that way in I have changed petrol cap,rear sprocket to alloy,Brembo gp4rx and a lot of oem nuts and bolts to ti pro bolt race spec and other shaped bolts,some will say I'm silly spending so much and ti for not much gain but it's my hobby and I enjoy it.I am only going to do this quickly as of now but to let you no how far I have gone with TI not alloy fittings even the bolts that hold the rear plastics under solo seat cowl and number plate bolts and nuts are TI,In cost for Probolt TI around $1600 Aus so far but as I said this is just a update,so My wife just surprised me with some digital scales so I now can get some ideas on my weight lost so far(I no Ti is around half that of steel hardware.I am still slowly getting there with TI and once I get a chance(arm in a cast) will get the bike back on the scales but I no one thing my bike will be very very close if not less than the current 2013 SUPERbike world champions ZX10R I think lol

very nice, ive done the same... i was thinking about rolling into a local scrap metal joint and ask for a reading :) didn't know where else I could go to weight the bike?
 
#13 ·
the sad thing is, im doing the same thing to a bike thats almost 10 yrs old lol

whos the dummy here, me, you or both of us

ive chalked it up to it just being a hobby man, dont care what anyone thinks about my money spending towards my bike. wife is good with it, and its not like we are dumping the money at strip clubs or drugs. we are able to get satisfaction out of the progress we make. and it doesnt matter why we do it either

IM WIT YA PETER!!!!!

If you have the usual Ti bolts, exhaust, rear-sets, clip-ons, battery, cf wheels, ect. Then I would remove lights, ignition, secondary flies shaft and servo, radiator fan, strip wiring harness, custom kill switch, aluminum triples, tubular sub-frame (contact yoyodyne), and custom gas tank. Should get ya were you wana be.

^ in regards to that, they even make carbon fiber subframe rails at carbomoto, or you can get the aluminum tubular joints that CBC-saller makes - but gas tank? Haven't seen any options for the genIV yet, except that double capped endurance tank...?

Thanks Haga yea that's a good idea I can check our local speed shop (which is mainly auto) but they've got a race team and some sick cars, plus they're pretty big so maybe they've got a good scale for me to ride onto... I'll keep ya posted, need some warm weather first

all i'm sayin is, if its to do strips or road racing, measure your gas. replace your battery. ti exhaust, thin plastics, light tires, alum sprockets, thats all you need. if its just for shits n giggles, enjoy spending lots of money ti nuts n bolts lol save your few grams here and there, just dont forget to take a shit before throwing a leg over and nullifying those expensive shed ounces ;) i dont care what ya do to your bike, i was just wondering the why, cuz then we can give ya the how but if its just for funsies, then have at it! fairfax it up lololol

Agras support Brembo gp4rx rear

We'll I have weighed all oem brake caliper hardware,support and caliper and it is 1062grams
Agras support and Brembo caliper and all Ti hardware..1066grams
I will be changing the m/c to Brembo to suit the caliper and will give you my view on stopping power compared to oem as soon as it's all done,the under slung does make it easy to change out pads if racing and would bring down the c of g in weight but for a street rider it's nothing but bling factor full stop..........I am being honest
Now for overall weight lost on the rear wheel(unsprung)
Alloy sprocket,full ti hardware,mm disc,Ti axle nut and adjusters and Brembo set up
880 grams and the cost in Aussie $$$1520
I am being totally honest and my next comparison will be the front unsprung weight
Brembo gp4rx and full ti hardware stay tuned its a time taking job

Weighing your bike on scrap yard or truck stop scales wouldnt be close enuf..Most dont get calibrated often enuf and are usually off...Best place i would suggest is the dept of transport scales that commerical transport uses..Or airport,they are weight sentitive..

Trading money for weight is a nice way of putting it haha! 180 kg with almost full tank is very nice,it means you are close to 168-170 kg without fuel.

I'm doing the same with my k7 1000 GSX-R for the past 4 years, ( I know,shame on me for throwing money on thee gixxer),and I think I'm at a good point.

I weighted the bike at 158 kg ( and it's 195 hp also) and I still have parts at home I haven't installed like CMC rotors (- 1.5 kg) ,Pankl titanium rods ( -550 gramms) and some other mods in mind which will get me down to almost 150 kg ( without fuel in the gas tank),

I have also changed some of the bolts with Ti ones,but I've found out that you have to start from where the big gains are first,axles,rear linkage and engine bolts are where Kgs are hidden not just gramms...


I have also gone to some extreme measures,like removing all of the unnecessary wiring from the wiring harness,this was an easy and cheap -500 gramms.


I have also made a cf subframe,fairings air ducts,clock bracket and exhaust hanger are all cf, PVM magnesium rims, I also have an STM slipper clutch with aluminum clutch plates in it which was 800 gramms from stock...

This is how it is for now.

Ι'd really like to get a cf gas tank like ETI fuel cell etc,my gas tank is 6+kg and ETI for previous GSXR models is 2.5 kgs... :badteeth:


It's a never ending game you will always try and find out ways to remove weight from the bike :eek:ccasion1

Dang, 158kg thats super light. I was excited about 365-370 lbs wet and I had similar mods. My 08 track bike with tubular subframe and no dl1 dash 2 hooked up is around 370 and I seriously doubt I can get down to 350 even if had tank stand alone and dash. There simply isn't anything else I can do to lighten it.

I found ti nuts and bolts very cheap

We'll after spending 1000s on Probolt ti I have found a would you believe Aussie supplier that would of saved me more than half on Probolt easy!I am still changing and have received there product and if your after basic ti hardware this place is amazing,ok here is a example a tapered socket cap 10mm1.25 thread and 70mm long to mount front calipers on a gen 4 in Probolt is around $23.00 Aus!! These new bolts are under $9.00.They are made in China but don't make judgement until you check them out,they are rated exactly the same tolerances as Probolt,Mettec bla bla,ok there not as pretty as some but overall Finnish is very nice and this company supplies the aero and defence company's world wide and if you want to check out there business the company is Yonsin,I am in communication with the Aussie supplier who is a suspension specialist who only does this as a little on the side instead of the other full on company's,now when you receive your bolts it doesn't come in a beautifully packaged bundle but if it's the difference of at least half in price give me plastic wrap and sticky tape any day and I having the gen 4 parts pdf and swapped out $3000 worth of hardware I am giving him bolt sizes to do kits for this bike and first kit will be the engine kit like Probolt does for $440 so stay tuned.I will not be making any money,hardware or shifty little side kicks because I no what it cost me and helping another Kawa owner to get amazing value for your $ is good enough for me,these bolts are designed to be as strong as steel,40% less in weight and there for a purpose not just for looks and will post up a engine kit price soon

Awwww.... I spent all winter doing this. And now you found someone to do the same thing, put it in a kit and sell it? Well guess it will make things easier for the track bike :)

Sidenote: while pulling all the hardware this winter I was surprised how much it added up to. Somethings I couldn't do in aluminum or titanium simply because I couldn't find anyone out there that had anything. But if you found a guy that can do EVERYTHING and will package it and sell it.. that's frickin' awesome. I'm in.

He is building a new site and I have spoken about my frustrations with not having a Australian supplier in Ti automotive hardware! He can get most colors even black (vacuum treated) and torc heads and price goes up accordingly, I was up front with my disbelief in his prices apposed to others and told him that there's a opportunity to sell his product at a nice profit and destroy the opposition, 2011-2014 ZX10R 6mm engine kit sells for $380aus! Using the same tapered socket cap with his prices on his site is well under $180! that's nuts check out his site it's mainly his suspension shop (Hyperpro etc)
Y.S.S suspensions Australia

180kg with a full tank is fantastic and easily reason enough in itself. You enjoy it so enjoy it and sod other's opinions. I know if most bike fans see it in the flesh they would stop and have a gaze at all the improved details. It is gorgeous.

Lightweight carbon bodywork next..?
