I rode a stock R6 last year for about 3 months and didn't really care for it on the street. The power was so far up in the RPMs it was virtually unusable. The R6 I rode last night was totally different. The one-down, two-up sprocket set up put the power right within in reach and made the bike a joy to ride. Sprockets maybe be dollar for dollar the best mod you can make for a bike. What do you think?
