Does that front rim have the casting in of the tone wheel holes for the 14? No tone wheel, instant code once the key is turned on. Next is the intervention kicking in. Say the tone wheel does have a bolt up place on the rim, now you have a formula breach.

Starting out, the ratio is going to change and you'll feel this low speed electrical on/off kind of bumping/hesitation, then goes away. No biggie if you can deal with that every time you stop, take off again.

Then you have this gear ratio change for top end, but nothing downstairs like it once was. Add the chain link difference, where you might have pulled the wheel all the way back and it's still sloppy on the chain slack.

Next is to cut the OEM link to take the original chain off, that, or pull the swingarm off so the chain remains one solid chain, no master link with this kind of power.

Or, sacrifice the OE chain, cut it, toss it, buy a new chain with a link less kind of count. That, or buy it long enough chain and then remove said links to fit. This way, the length of the F-axle to R-axle is not extended and handling problems set in.

Conclusion:
Yes, this is top end ratio with a rear tooth removal for more MPH upstairs.
Yes, the formula for said stock ratio will/may set the intervention>> changing ratio.
Yes, the new chain will have to be staked with a special tool. No removable master link style... unless you like to eat an engine case with the chain wadded up and nowhere to go but make room inside the case.

i ended up with the 17/41 grearng. 2.71 ratio

hope its good to help with roll races but still having power down low

I plan on going with a 17/41 setup when my 41T sprocket arrives. My goal is to be able to be more aggressive with going full throttle in 1st/2nd gear without wheelies(more power to the ground), and at the same time maintaining/gaining top speed.

@Zxpredator how are you liking the 17/41 setup so far?

Thanks

Here's the low down from my experience with running different setups against a 2021 BMW S1000RR while roll racing.

17/42- 2 runs and the 14R won both races.

16/43 - 2 runs and I got my ass handed to me both times. I was surprised since I geared it down (-1/+1) but the results were the opposite of what I was expecting.

I'm going to run against the BMW next time with my 17/41 setup and see if this will give an even better edge than the successful runs I had with the 17/42 setup. I've road tested the 17/41 running on the back roads and it seems to be much quicker than my previous 16/43 setup since I'm able to give it more throttle without having to worry about wheelies.

Siroht, did you ever get the results for that 17/41 setup im currently running 16/45 which is -1/+3 more of a street/strip setup but might go back down some on the rear might stay at the 16 front though, im trying to find a happy medium.

Honestly I've been all over the place with trying different sprocket combos and ended up going back to stock. Anyways I haven't had a chance to race the S1000RR since we have been missing each other and the weather has been hit and miss in my area. I have been handing beat downs to 2 of my buddies who own a flashed/tuned/full exhaust 2017 GSXR1000 and a 2021 Hayabusa that's also flashed/tuned with a full exhaust. I easily pull out on them on the hit and continue to widen the gap as the race progresses, and this has been with the 17/42 sprocket setup.

In regards to the 17/41 setup, it is a tad bit modest in regards to acceleration, but it does allow the bike to access it power earlier on without having to worry about throttle control/wheelies say like during a first gear pull from 5K. Since I recently stretched my bike I again tried higher gearing, 16/43 and 44, and although I was getting mad acceleration in 1st/2nd gears without the wheelies(stretched)...I didn't like the early shifting because of the higher gearing. Therefore this lead me to go back to a 17/42 and try it with the stretch setup, and honestly the down low strong acceleration is there, especially since I don't have to modulate the throttle on the initial hit.

I have a -1,+1 setup on my ZX10R due to its lack of low end grunt and the regarding is definitely needed on it, but I've come to the conclusion that the stock sprocket setup on the 14R is a happy medium at least for me. I think this has to do with the massive amount of torque that's on tap early on in the RPM range. Now if I decide to hit the strip this coming Spring, I will definitely gear higher, but based on my experience and for a street application bike, it's hard to beat the 14R's 17/42 setup, unless or course a person's needs call for something different.

Thanks, my 2017 is fbo lowered and stretched about 10in i might buy a new 42 rear an run 16/42 on the street to see how it does depending how it feels maybe go back to stock 17/42 thanks for the imput.

Keep in mind tire diameters, which can even change make model will change your effective final drive. Popular to go to 190/55s, which slightly gears the bike up, if I recall it's actually a tooth or two off the rear sprocket.

I am not surprised at all 14's may benefit from slightly lower gearing over higher gears especially for top end. I have often felt like some people undergeared their hot rods for example. I mean, someone who has a top speed of 115mph may feel like their getting their quickly... but then I guess if that's as fast as the car can go you can only plan on doing 115 in the quarter.

Once my OEM size tire expired, I jumped up to a 200/55/17 and I'm loving it, which according to gearing commander this change in tire size equates to going down 2 teeth in the rear.
