! Thats where i got my kit. you can choose the gearing you want by going down one or two in the front and going down one or two in the rear. Go with a 520 RK GXW 520 chain and Vortex sprockets both front and rear!. not sure on the stock gear in your bike, but go down one in the front from the factory front gear and go UP two in the back from factory gearing. The stock gearing on my 04 R6 is 16 front 48 rear. I went with a 15 front and 50 rear and the GXW 520 chain! This will give you optimum performance out of the kit. It is the true quick acceleration kit!
The RK GXW chain is rated at 8,000 pounds tensile strength while the RK XSO chain is rated at 6,000 pounds tensile strength. Just go with the GXW its only 10 bucks more and is stronger! RK chains are top notch!
The kit i just mentioned you can get it to your door for 172.99. 164.99 for the kit and 8.00 to ship!
