Fork oil viscosity affects how quickly your forks compress and rebound; a lower number flows more easily for a softer, more comfortable ride, while a higher number resists flow for firmer, more controlled damping. If 7.5W doesn't feel quite right once you've tried it, our 5W and 10W fork oils sit either side, or take a look at our full motorcycle fork oil range for every weight we stock.

Some riders blend equal parts of 5W and 10W to approximate a 7.5W oil, though using a ready-made 7.5w fork oil ensures a more consistent, predictable result.
This varies by bike and use, but many manufacturers recommend changing fork oil every one to two years, or sooner for track or off-road use where the oil works harder.
