RPM at given speed

[Ramblin Robb]

Without a tach, I am wondering what rpm’s are going on at 30mph, 40mph & 50rpm…
and anyone know what rpm redline is?
Thanks!

A big question is... why do you want to know? There's a rev limiter that stops it going too high, which according to unverified Youtube is 9500 RPM. In top gear (or pretty much every gear except 1st) it doesn't have enough power to pull through to the danger zone though.

Unsurprisingly, when Warro tested the engine at top speed, he found it at... basically the maximum torque band RPM of about 7350 RPM.

RE: Speed at various RPM, that depends very heavily on the bike set up itself. The tires (knobby, slicks, also width), the gearing, and if you mean GPS or indicated speed (and indicated on stock electronics or the aftermarket OPMID display) are all factors, as is rider and accessory weight. I have the OEM tires fitted right now, but plan to go up to the SR244's on the next tire change, and will be fitting the OPMID cluster on the next non-raining day I have free, for example.

https://www.gearingcommander.com/ should give you a reasonable estimate based on calculations though. You could also buy a cheap clip on tacho with 4 digit display and run the numbers yourself.
