BMW K100 Marrakesh [1983–1991] - K-Series Fork Cartridges

Modern internals for the original fork

This pair of adjustable fork cartridges replaces the hydraulics and springs of the original fork. The system was developed according to Unitgarage specifications to combine the fork's classic exterior appearance with performance-oriented tuning.

Hydraulics and adjustment options

• Advanced hydraulic system
• Pistons with enlarged oil passages
• Adjustable compression damping
• Adjustable rebound damping
• Adjustable spring preload

Version and identifying features

This is the 105_W06 model with a threaded cap. As BMW used different suppliers and fork designs for the K models, the existing fork must be clearly identified before installation.

• Cartridge foot screw: M10 × 1,5
• Fork length: 810 mm
• Reference for the version described: Marzocchi fork with 41,7 mm diameter
• Specified for K1100 RS with motorcycle production year 1993 to 1997

The cartridge foot screw passes through the fork foot and secures the cartridge in the lower section. Fork length is measured with the fork fully extended, from the center of the wheel bolt to the end of the chrome-plated fork tube. The resistance of the internal counter spring must be overcome to extend it fully.

Scope of delivery

• Two fork cartridges for the original fork
• Matching springs

Installation and safety

Correct installation is crucial for riding safety and must be carried out by an experienced technician. Unitgarage recommends using Öhlins fork oil in the quantity specified by the manufacturer.

Note: No ABE, No TUV

Compatibility

Listed for BMW K100 sKrambler and K100 Marrakesh. Due to the different fork designs within the K-Series, the design, dimensions, threaded cap and cartridge foot screw must be checked against the specified identifying features before installation.

Unitgarage continuously refines its products in detail. The images may therefore show an earlier version.
