The BMW F800GS in stock trim is a good bike, it does however, feel too soft and mushy when the bike is ridden aggressively, both on and off road.


The first issue is the bike is equipped with a non-rebuildable cartridge that is sealed and can not be modified. The only improvements that can be made to the stock cartridge is changing the oil weight and spring rate. This improves performance but is still not enough for more aggressive riders.

Race Tech has developed a complete G2-R Cartridge replacement. The kit includes our 25mm G2-R Gold Valve and adds externally adjustable compression and rebound. Another factor contributing to a soft feel is the stock fork spring rate is very light, .44kg. The G2-R 25mm Cartridge kit and stiffer HP Forks Springs address the issues of the F800GS front end.


The rear shock is also considered non-rebuildable in stock form. The only thing that keeps it from being rebuildable is the inability to recharge the shock with nitrogen. We can add a SPNV 0812 Nitrogen Charging Valve to make it rebuildable. This allows us to use a Gold Valve and, with the selection of the proper spring, the stock shock becomes a great performer.

>G3-S Custom Series Raplacement Shock

If you want the ultimate we also have a whole new shock, the G3-S Custom Series Shock. This shock comes with a custom setup Gold Valve, externally adjustable rebound and a RT Hi-Performance Spring also selected for your riding. The shock is fully rebuildable and revalvable. It's the perfect balance with the G2-R Cartridge Fork Kit.
