Gearbox oil?
Posted: Thu Aug 15, 2019 12:59 pmHi folks. What gearbox oil would you recommend for my 1972 ES250/2 Trophy?
Many thanks
Many thanks
Best look in the manual for that bike (which I do not have), but I'd guess it's very similar to later ETZ's, for which they prescribe EP 80.
As the clutch sees that same oil, best NOT use an API GL-5 oil (containing high levels of molybdenum disulfide, to cater for more Extreme Pressure), but instead a more classic GL-4 oil. Viscosity SEA 80, or 80W-90, or 75W-80.
