Description

This top of the line F850GSA fork cartridge kit fits into the right fork leg without modifications to the fork. The cartridge is closed, meaning that the cartridge is like a separate, pressurized shock absorber inside the fork with its own damping fluid for optimal performance. 

These 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 improving off-road performance while retaining comfort for on and off road use. This is largely due to the huge size of the damping piston at 35mm in diameter. This size of piston is the largest of all aftermarket suspension providers. Apart from a high oil flow, this piston size allows for stable and well-controlled damping behavior. The size of the internal bore also allows the use of electronic systems on Dynamic Damping models, and the cartridges were also further developed for use in road racing. 

This cartridge design has proven to be reliable and finely tunable. 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 and there is a wide range of springs available to suit every load and riding condition. The fork retainer cap at the top of the fork provides easy access to the adjusters, and contains a deaeration screw to equalize pressure buildup which can be common in telescopic fork systems. At the end of the stroke there is a hydraulic anti-bottoming system which prevents hard bottoming over large impacts. The adjusters provide 20 clicks of damping adjust and 12mm of preload adjust.

Comes with:

  • Fork cartridge fully assembled and ready to drop into right fork tube.
  • Fork oil.
  • Fork adjusting tool.
  • Fork cap tool.

Additional Notes: 

Fork oil is just for lubrication, cartridge is sealed, closed, and runs its own oil.

Since you are replacing only one cartridge, you will need to set the height of the tube with the new cartridge in the triple clamp so that the axle slides easily between both slider tubes. The top of the right tube may sit a bit higher than the left tube, this is perfectly OK. Start with the right tube   
protruding above the top triple clamp by 5mm and then adjust this height until the axle fits smoothly through both tubes.

Tractive recommended air chamber is 65mm for general use, 60mm for more off road riding. Air chamber is the measurement of the oil level to the top of the tube with spring removed and fork fully compressed.

Available in standard height and 25mm lowering.

While professional installation is recommended, owner installation is possible if you have experience with cartridge forks.

I bought my 850gsa as an upgrade from my 800GSA and the front end was still very soft on this bike. After chatting it through with Ted I opted for a front fork upgrade and a new steering damper. I rode the hell out of the bike in MAX BMW’s wheels in the field event in October and I think I would have folded the fork with the stock suspension. Bike is more predictable and forgiving to the big lumps and I feel like I’m riding a completely different new bike. Best money I’ve ever spent on upgrades for any of my bikes. DO IT!

“The dive has been reduced by about 70%. Feels much more in control at stops. I don't have to brace myself coming to a red light. The mechanic thought the spring might be too soft (Beemershop note: it wasn’t too soft, the mechanic was 280 lbs, it was setup for the rider who was lighter, not the mechanic) but he was a big guy. It is still a huge improvement. Rebound control is excellent, I had no idea how bad it was.” Stephen T. F850GSA
