Been out for a ride tonight, Rpm is 5500 at 100 mph with a 37 rear sprocket, Looks like i should go with the 39t rear.


opps forgot to mention, test was done on a private road

Interesting - tried it the other day 100mph = 5600rpm on a 41T rear :devil:

I told the officer I had to try this test out for DSC purposes!

Frank what front sprocket you using?

When you're comparing speed/revs on bikes, make sure you really are comparing like for like. Quite a few changes were made to primary drive ratios through each models life.

Not sure what the other bikes are but ive got

97 SL MK5 15 front 37 rear and at 100 mph pulling 5500 revs

Ah! Now I've also got a 170/60 section rear tyre (newish Pirelli Diablo). I reckon a 180/55 section rear tyre would affect it somewhat also.

Interesting all the same

Paul has a very valid point about final gearbox ratio's

Red-Duc, front sprocket is a std 15T I believe.
