BMW S1000XR 15-19 Front Cartridge kit eX-CELLENT

High performance cartridges for demanding riders. X-TREME and X-CELLENT are similarly built with a different rider in mind. Where the X-TREME was designed for both on-road and adventure, the X-CELLENT is on-road focused.

The cartridges are designed for ultimate feel and control under varying loads and riding conditions.The cartridges are closed, meaning that the cartridge has specific damping oil and a separated, pressurised nitrogen gas chamber. The largest cartridge piston on the market, with 35mm diameter, ensures a high oil flow and a stable, well-controlled damping behaviour.

The X-TREME cartridge is designed for adventure motorbikes and has a hydraulic end stop to prevent bottoming during hard impacts.

The X-CELLENT cartridge is developed for road and sport bikes. Inside the cartridges are top out springs that create suspended negative travel, allowing the fork to move easier at maximum extension during acceleration. This maximizes grip keeping the bike more stable, improving safety and performance.

The large size of the piston allows the use of the TracTive electronic DDA valve for motorbikes with electronic suspension adjustment. The electronic eX-TREME and eX-CELLENT cartridges fit Plug & Play with the original connector. Damping is controlled by the motorbike’s control unit and original handlebar buttons.

Description

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 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.

These cartridges fit plug and play into the motorbike with the original connector. There is no need for cancelation kits or other modifications to the motorbike or its wiring harness. The motorbike’s control unit does not notice electrical differences between the original damping valve and the Tractive DDA damping valve. However, the Tractive DDA vale is more stable, has a larger adjustment range and adjusts faster than the orginal valve.

Inside the cartridge are top out springs that create an easier moving fork for accelerating out of corners. This results in a longer grip and prevents the bike from going into a headshake.
