One of the guys on the Strom forum set this up. Pretty cool.

sweet! i love sticking a bunch of numbers in my head, i just dont know what happens with them from there

wow, apparently my gsxr tops out at 141mph ...

dont tease, that sprocket was cheap!

Apparently my Rex tops out at 160. Seems pretty accurate, i've seen 167 on it indicated and I'm sure that was pretty high at that speed.

Right KB?

It's a nice program, however there is one very important piece of information not included. The rear tire diameter. Different tire brands have very different tire diameters in the same aspect ratio. For example a Dunlop 180/55-17 D209 is 6-8mm larger in diameter than a Michelin 180/55-17 Power Race. If you do the math you'll find that for every 10mm difference in diameter, it equals approximately 1 tooth difference in the rear sprocket.

I have actual tire diameter measurements that show the 180/55 series vary by as much as 15mm from brand to brand. the program should remove the aspect ratio section and replace it with tire diameter. Then it would be more accurate and the about the only variable would be in the actual rolling diameter vs. the measured diameter.

But this way the ricer's have something to argue about.
