Being that I have no idea what the trans. gear ratio is, pulley diameters are...

What is the engine RPM at 75mph, (high gear)?

Thanks

Mike

I'm indicating right at 4900 RPM @ 75 MPH.

What about the R?

Great
Thanks a lot.

Sounds small, but that may have just sealed the deal on buying an 1125CR rather than an R1.
After talking to a Buell Engineer Friday night at the Long Beach Bike show and this...it's sounding better all the time.

I rember reading in the info from Buell (or maybe somewhere else) that it works out to about an 8% difference in final drive.

Boy does the thing snap when you jump on the throttle. Wheeeee!
