j hancock Posted January 7, 2017 Share Posted January 7, 2017 With 22.5 approx speed of 68@2000rpm and 24.5 would be approx speed of 71@2000 Quote JimIt doesn't cost anything to pay attention.

j hancock Posted January 7, 2017 Share Posted January 7, 2017 Yeah, I guessed at the rpm because I didn't ask which engine you are working with. 22.5 = 58 mph 24.5 = 61 mph Quote JimIt doesn't cost anything to pay attention.

Vladislav Posted January 7, 2017 Share Posted January 7, 2017 (edited) I have T2090 with 5.02's in my R688 with E6-350. You can cruise 60 mph (100kmh) with no trouble. The top speed I could achieve was 125 by speedo and 119 kmh by GPS at the same time. Unfortunately my tacho is dead so no ideas on the revs. I just noticed the engine didn't increase revs at some point so I supposed it was governed that way. Forgot to add, I rode 11R24.5's.
