Usually not enough to affect your drivability in a street setting..please dont starting posting in here about how your bike does 170mph and +2 in the rear will lower your top speed...

RPMs will be higher to maintain the same speed than before a bigger rear sprocket....

What year and type bike? What are you trying to accomplish? Less RPMs at speed?

Ahh ok...yea u will want to go smaller sprocket in the back or bigger front if possible. Get on a ninja 250 forum and see what everyone is doing. Front sprocket changes are easier and usually dont require any changes in your chain length.

1 tooth change in the front is like 2 or 3 teeth change in the rear.

Dont even waste your time. If you gear that bike to run lower rpms at 70 it will be a total . The lack of tq is what requires the stock gearing. Changing one to raise rpm's and make the low end is one thing. Changing to lower rpms at freeway speeds is something you only do on a bike with enough tq to turn taller gearing. That is not the case with your bike. You need to just be happy with its current rpm's

Swap to a 15f front sprocket. This will lower your Rpms roughly 1k. That's what I'm running. If you wanr to drop more than go -2 or -3 in the rear sprocket. Just remember that it will take more time to get up to speed.
