BMW F 850 GS Adventure Fork Cartridge kit X-TREME
High performance closed cartridge with adjustable damping. Manual preload adjustment.
These cartridges fit right into the fork legs without modifications to the fork. The cartridges are closed, meaning that the cartridge is like a separate, pressurised shock absorber inside the fork with its own damping oil for optimal handling. The products were originally developed in close cooperation with adventure riders, world travelers and rally riders. The products have proven their value over the years: hugely improved off-road handling while retaining comfort during long travels. This is certainly also due to the huge size of piston used: 35 mm diameter. This size of piston is the largest of all aftermarket suspension providers. Apart from a high oil flow, this piston size allows for a stable, well-controlled damping behaviour. The size of the internal bore also allows to use electronic adjustments. Later on the cartridges have been further developed for use in road racing. Again the cartridge design has proven to be stable and finely adjustable. Every cartridge can be easily opened and serviced. Or the damping can be tuned for the customer's application. Spring rate, spring preload and air chamber are easily modified, there is for every product a range of springs available pending on loading and application. Every cover cap contains a dearation screw to remove an excess of foam and air.
The damping can be adjusted on one leg with a noticeable change with every click. The damping adjuster affects rebound damping and compression damping in a natural balance. In both legs the spring preload can be adjusted.
At the end of the stroke there is an hydraulic end stop. This helps with preventing hard bottoming during large impacts.
