The manual says Recommended Gear Oil: SAE90. Can I use some left over Red Line 75W90 Gear Oil? It is rated GL-5+. Are there brass parts in a CVT scooter transmission?

Ive never found any brass parts in mine, and have always run 75w90 synthetic.

Anyway GL4 is an overkill for any scooter gearbox...

A fill of GL4+ syn gear oil in these is basically lifetime.

Its only the final drive that gets gear oil so no synchro rings etc. The auto-transmission is belt and cone and is not lubricated.

I use 75/90 GL5 in my scooter final drive - it's just some spur gears. I guess it picks up about 0.01 hp with the reduced drag...and you can really feel it.

I never found brass parts in my final drive gearbox of my Piaggio scooter, I used Motul Gear 300 75W90, fully synthetic. I figured the less friction losses the better in a 125cc scooter.


I wouldn't consider it a lifetime fill, even tough I know people that changed their gear oil for the first time after 30.000 miles, I changed mine after 1500 miles and then after 1500 miles again, and the gearbox oil was dirty. And were Bitog members after all, there's no lifetime fill for us :-)

Burgman 400, Yamaha Majesty, and Honda Helix use 10-40 motor oil in their final drives.

I use M1 75W90 Synthetic in all my scoots with ZERO issues. You'll be fine. Even in the two that call for 10w40 motor oil (Honda Elite 250 and Honda Helix)
