What sprocket combination for the 10R? So.. I just rode my 12R, and again I immediately noticed the difference in the low end power delivery... so my question is this.. what sprocket combo is needed to put the 10R at about 6 grand at about 25mph?
Math people out there?

I have this little utility that a member (sorry cant remember who) created for us at the debut of the 12R.. it calculates the RPM depending on gearing and tire size.... can some one modify it to fit the 10R here's the link to download it...

I have a spreadsheet I made up with all this info. I use it to bench race my bike. Anyway, stock here's the rpm vs speed.
17 T front/39 T rear
RPM Speed
3000 23.3
4000 31.1
5000 38.9
6000 46.7
7000 54.4
8000 62.2
9000 70.0
10000 77.8
11000 85.6
12000 93.3
13000 101.1
13500 105.0
The sportrider dyno ended at 12500, but I thought it was supposed to rev to 13500.
If you want 6000 rpm at 25, you'll have to gear the sh!t out of it. The combo 15 front/50 rear would almost do it. That gives you 25 mph at 5000 rpm (not 6000). But with gearing that extreme, 6th gear at redline is only 130 mph.
My spread sheet has acceleration vs speed graphs. I'm convinced Sportrider stole the idea recently. In my comparison of a stock busa vs stock 10, the busa has a huge advantage until 70 mph. It's shorter gearing plus huge torque, will tear ass in first. After 70 mph, the busa runs out of steam, and the 10 comes on strong. That damn first gear is soo tall. The 10 has a clear advantage until about 160 mph. With equal riders, the 10 should spank the busa and 12 once upto speed. After 160, the busas will again pull harder to top end. To figure for aeordynamics, I had so assume a top speed for the zx-10. I guessed 180mph.
