YZF750R 6-speed Transmission


Recommended Posts

Greetings. I hope someone out there can assist. Does anyone have the gear ratios for the YZF750R 6-speed transmission?

I actually have two YZF1000R engines, one with the standard 5-speed, the other with the 6-speed from the YZF750R.

While I'm looking for the ratios for all gears, the final gear (6th) is the most important as I am trying to calculate top speed when using different gearing combinations on the rear end, and without the gear ratio data I am stuck.

Thanks very much in advance for the assist.
