Yes, there is separate transmission oil. As mentioned above it is the same product as used in the final drive. This is a good thing. You can use a true gear oil. The K bikes and like format bikes with the transmission sharing lube with the engine have to use compromise lubrication.Teach said:Is there gearbox oil on the RT?
I used Mobile 1 full synthetic 75w90 (GL5 spec).lkchris said:SAF XO is for final drive only. NOTHING ELSE.
Guess it wouldn't hurt in gearbox, but at $50/quart ... .
