i have read that it is possible to replace the Ninja 250's sprocket for a lower tooth count. i would like to know if this is possible for the Ninja 500 as well?

 

Yes - but which way do you want to change it. Better to fit a bigger rear sprocket than a smaller front if you want improved acceleration - it's kinder on the chain.

For lower cruising revs, fit a smaller rear sprocket.

thanks for replying..what im lookin for is more all around mpgs, i live in san antonio, texas, which is alot of highway, but also alot of city, so i will need low cruising revs, but it seems like the 500 already has those down well, so if theres a way to get more highway mpg and more city mpg on the side thats what i want to do
and idk if the 500 has problems w acceleration, but if that also means more acceleration on highway in the powerband then that would be nice..also if anyone can tell me about how much this might cost?

 

You're probably getting better mpg than 98% of the vehicles on the highway, with your stock sprocks. Mac, if you start going up and down teeth, you give up revs or acceleration. Can't have it both ways. Stock sprocks are pretty much a balance of both; you're at the middle of the bell curve.

 

The smaller radius puts more strain on the chain and sprocket.

But if you go up one tooth in the front, that is pretty extreme in your performance and stock tranny ratios. You can go down 2 on the rear to try out, you will still see the performance to rpm difference with possibly the mpg that you may be looking for. After riding the 500 around myself, stock gearing is pretty close for the street.
