Just do a -1. You'll want to buy a speedo healer as your speedo will will go from being 6% off to around 13% off. Most of what you'll notice in a -1 will be a reduction in the amount you have to slip the clutch to get the bike moving from a stop. You'll also notice an appreciable gain in 6th gear rolling on the throttle at hwy speeds. The bike will go from being at 5k rpm to around 5500K rpm at cruising speed. If you look at the dyno chart you'll notice a decent gain in HP going up 500 RPM. So, it will feel more snappy rolling on the throttle. I also run the +2 in the rear, and it makes it really nice, putting the bike in the powerband right around 6k RPM or just under around 75-80mph. So when cruisind on the freeway, I've got a noticeable increase in the amount of pull when rolling on the throttle in 6th gear as compared to stock.
Asain, in 1st gear, much better acceleration off the line too. Instead of the bike lifting the front end at 9.5k rpm in 1st, Now it lifts the wheel at 6.5k rpm when holding open the throttle, not whacking it open.
Anyway, def do the -1, just understand that a $20 sprocket when you add a speedo-healer will actually cost you $130. Plus install on both items, which is simple enough.

I'm -1/+2 and have a speedohealer at -18.9 and is dead on at any speed verified by a Garmin GPS. I now bounce off the limiter in 6th gear @ 167 mph. It won't go any faster. I'm considering going back stock up front and +2 in the rear.

You can pick up a 16 tooth sprocket anywhere really. I buy almost all my poo online at www.motorcycle-superstore.com. There are some good vendors on here as well like Superbike supply, which is where I bought my X-TRE and Speedo-Healer. Your looking for a 525 size, 16T sprocket for your bike.

I have ran -1 & -2 up front on a 3rd gen...I have a lot of sprockets haha...dropping to a 15/41 combo is just the same as -1/+2 basically give or take a couple .'s
I would say to you, just go +2 in the rear cause its the same as dropping -1 up front give or take a little..+2 will have a higher top end then -1 cause -1=2.3 something and +2 is just +2 hahaha...Can't explain this that well more of hands on type of guy when it comes to gearing. What are you planning to do with your bike? Track? Street? Cause gearing is base on what your planning to do...

tried -1 front with stock rear 16 - 41 & IMHO makes the gears too close I did not care for that gearing.... on my 08 ZX10
now running 17 front stock & +1 in the rear 42
& I kinda like it .....but have not been able to test enough yet to see if I like it better then the 17-41 stock gearing ?
I just put the new gearing on about a week ago
but so far I do like it way better then the -1 in the front

You won't keep up if you change out the gearing cause you will drop a lot. -1 on a 3rd gen on my gps will only do 170-173mph max...I like to say for every tooth you drop up front you drop about 5-7mph or more depending on the bike...
This is for the member above me^^^
In the case of mine -1 up front is actually slower from 0-100mph but it feels faster cause the rpm's sit higher etc etc...
I have tested a lot of setup's for the street and for the 3rd gen 17/41 or 17/42 is the best in my mind for the street...
THIS IS COMING FROM SOMEONE THAT HAS ALL THESE SPROCKETS TOO 15/16/17/18/39/40/41/42/43

On a first Gen because it's geared so high than any other 10R the limit is about what I run to do over 170mph as I run -1/+1 and the speedo healer still reported 180mph @ -11.1 %.....I know that's off a 1-3% max maybe but that's still well into the 170s. On a 2nd Gen 10R I would think a -1 and that's it to stay in the 170s. :dontknow:

:+2: I think your right on with your gearing advice I wonder what the gps says about top end difference mph between 17 41 vs 17 42 ?
do you know ?

I have a buddy bloo with a 2nd gen and his -1 up front is worse then any thing I have seen. On gps he can only hit 169. something compared to my 3rd gen which is 173. something
my bikes not stock at all but when I first got it on gps it would do 180. something flat with stock gearing and maybe about 178. something going into the wind. But +1 in the rear I'd say would be around 175 or something...+1=3-4mph difference...I have done a lot of testing and tuning with gearing cause a lot of guys around me like to run 9/10th's on the street

how about 15/36 or 16/38 to cut back on weight?

What year do you have and are you smoking something :lol:
If you have a 3rd gen stock is 17/41 and you just asked about running 15/36 or 16/38? Never tried those setups but I would think them to suck haha. I think you would have problems with either the revs sitting super high or it lagging like you have your bike setup for a top end pull at 18/39...How about you go buy those sprockets and tell us all. I'm doubting you will like those setups...
