About the Product

Öhlins STX 22 MX & Enduro Front Fork Cartridge Kit

Honda CRF150R (2013–Present) / Suzuki RM85 (2009–Present)

Race-Derived Suspension Performance for Youth Motocross

Upgrade the front suspension of your Honda CRF150R or Suzuki RM85 with the Öhlins STX 22 MX & Enduro Cartridge Kit. Developed using the same engineering principles found in Öhlins’ championship-winning motocross and enduro suspension systems, this cartridge kit dramatically improves front-end control, damping consistency, and rider confidence on the track.

Specifically designed for 85cc and 150cc youth motocross bikes, the STX 22 cartridge system replaces the OEM fork internals with high-precision Öhlins components, delivering smoother suspension action, improved traction, and more predictable performance over jumps, bumps, and rough track conditions.

Performance Benefits

• Improved front-end stability and rider confidence

• Faster suspension response over bumps and jumps

• Reduced harshness with stronger bottoming resistance

• Consistent damping performance throughout the entire fork stroke

• Increased traction and front tire control

• Predictable suspension behavior for racing conditions

The system delivers quick and continuous damping response, slowing suspension movement smoothly without harshness and maintaining consistent behavior throughout the race.

Advanced Öhlins STX Technology

STX 22 Cartridge Design

The STX 22 system is based on the same design principles as Öhlins’ larger TTX motocross cartridge kits, delivering professional-level suspension performance for smaller displacement racing motorcycles.

Low-Profile Top Cap

The cartridge top cap sits low above the fork tubes, allowing the forks to be mounted higher in the triple clamps. This makes it possible to slightly lower the bike—ideal for smaller riders in youth racing classes.

Easily Accessible Adjusters

Click adjusters and air breather valves are angled outward beneath the handlebars, allowing quick suspension adjustments between motos.

Reliable Damping Consistency

The spring-pressurized internal system compensates for temperature changes and ensures consistent damping performance during aggressive riding.
