sprocket/propshaft rpm
pathfinder - 12/10/05 at 05:27 PM

Evening chaps,

Does any one on here know the max rpm in top gear of there gearbox sprocket/propshaft (Blade, R1, Busa etc) just curious as to how fast they spin! I probably could work it out but thought I’d ask first!

Cheers

At a guess, around 7000rpm when flat out, assuming approximately 12k red line on the engine, 1.6:1 primary reduction ratio (ratio of crank rpm to clutch rpm), and assuming a 1:1 top gear
