How Often To Change Motorcycle Gear Oil. While some race teams use thinner oils they are working to very strict tolerances and controlled operating temperatures whereas on your road bike on the road the oil needs to work at a greater range. Gear oil lasts a long time as long as it doesnt get water in it.
Our answer will always be to check it as often as possible. Use EP 90 gear oil which is specially designed for this purpose as they have to withstand extreme pressure conditions. Depending on the model of the bike you possess and the year in which it was manufactured gear oil needs to be changed accordingly.
You should change it every 5000 km or every second service.
Even if you dont change it it should be periodically checked and topped up as needed. Photo by Claude Fabry.
