DescriptionThe whole story▼
GP5 is the step Wilbers took after its Zero Friction fork oils. Working with a large laboratory, Wilbers set out to raise the quality once more, and the result is a front fork oil in SAE 5 developed with the focus on clean response and controlled damping.
Key Features
- Next evolution of the Zero Friction oils
- Developed together with a large laboratory
- Viscosity SAE 5
- Made for racing forks under high braking loads
- 1 litre bottle
The problem it solves
Racing forks see huge sliding pressures when the rider brakes hard into a corner. Under that load a fork can stick for a moment before it moves. Wilbers built GP5 so the fork keeps moving through those phases instead of hesitating.
When the oil is not enough
Oil changes how the damping feels, but it cannot move the limits of the valving. If your fork's clickers cannot reach the damping curve you want, the shim stack has to be changed. Wilbers offers that revalving service, and we can arrange it for you.
How to use it
Fill to the oil level or air gap given for your fork. Mixing GP5 with another oil is not a good idea: drain and flush the old oil first, then refill with GP5 alone.
Who it is for
Riders who race or ride track days on a sport fork and want the oil Wilbers developed for exactly that use. On a touring bike the Zero Friction range is usually the better match.
Bottle size
The litre bottle covers a fork service on most sport bikes. Racing forks with large tubes can need more, so check the fill quantity in your manual before you start.
