Phil,
I get approximately 4450 RPM in 5th at 70 mph for a "stock" Vmax ...
this would be a "stock" Vmax with a 12.47 inch rolling radius tire. If
your 18 inch tire had a 12.47 inch rolling radius it would be the
same. I need either your rollling radius or the number of teeth on
your front and rear sprocket, (assuming your primary drive and
transmission gears are stock), to compute the rolling radius before I
could tell you what your 18 inch tire would do on a stock driveshaft
bike.
