Since my CBR250R will be my commuter and hypermiler (the Ninja250 will be the "fast bike/ fuel hog") I am going to play with longer gearing. Has anyone seen any larger front sprokets available yet? I may eventually go up as much as 17% total with changes to the front and the rear sprokets making it into a 5th gear/ top speed bike with overdrive to put 70mph highway cruising right at the first torque peak of 6000 rpm in 6th.

We will look forward to hearing your results with spocket size experimentation...
