i was wondering what to expect, exactly how torquy does this mod make a cbr600rr feel, will it make 2nd gear feel as torquy as first does now without the mod? i want to be able to rip the front off the ground like it does in first

 

I just installed a -1 sprocket in front and while I'm not sure what a +2 will do in the back, I can tell you just the -1 in front gives my bike a lot more torque off the line than stock. Makes pulling wheelies easier Other than that, I just had to train myself not to gun the throttle off the line as much as I did when it was stock. My takeoffs and acceleration is definitely quicker. I suspect the addition of a +2 in the back would give it even more torque, with the only side effect being my speedo would be slightly off.

 

I have a -1/+2 setup and its much torquier than stock. Definetly alot of fun. Speedo was off by about 17% at the end. Just make sure to order a Speedo Healer too if you do it so you can make your speedo give you the right numbers.
