My RC8R is track bike, I got it second hand and the previous owner went down one tooth in front. With 16/38 it was too long for the track, just barely redlining 5th gear at the end of the straight. So I tuned it, now pushing 157hp on the wheel, and went up to 40T on the rear, but now im planing to get quick turn throttle tube ( screw from surgery in my right wrist stops me from opening fully at one go) it will be too jumpy, so im gonna tame it down a bit with 39T rear.
On top of that we got a lot of humidity here, so from May till October, track can be pretty slippery and opening gas can be very eventful in some corners over here. A lot of good riders got caught there. Again it's all my personal preference based on the tracks that I'm riding on.
I just saw upper posts, bro if you are a new rider be careful with opening throttle with that sprocket setup. That bike has no electronic nannies to save your *** if things go wrong. I'd suggest , and other guys please correct me if I'm wrong, tame it down an bit, get a smaller rear sprocket ( batzang.de has them) or progressive throttle tube from KTM until you get used to the torque.
