About the Product

Öhlins STX 22 MX & Enduro Cartridge Kit – FCX 0104

Yamaha YZ65 (2018–Present)

Race-Derived Front Suspension Upgrade for Youth Motocross

Give young riders a competitive advantage with the Öhlins STX 22 MX & Enduro Cartridge Kit (FCX 0104). Developed using technology derived from the larger Öhlins TTX cartridge systems used in professional motocross racing, this kit delivers dramatically improved front-end performance, control, and rider confidence for smaller displacement motocross bikes.

Specifically engineered for the Yamaha YZ65, the STX 22 cartridge system replaces the OEM fork internals with advanced Öhlins damping technology, providing smoother suspension response, improved traction, and consistent damping behavior throughout the entire fork stroke.

Designed for competitive racing environments, this cartridge kit ensures predictable suspension performance during aggressive riding, jumps, and rough track conditions.

Performance Benefits

• Improved front-end control and rider confidence

• Faster suspension response over bumps and jumps

• Reduced harshness while maintaining strong damping support

• More consistent damping performance throughout the fork stroke

• Increased stability during braking and corner entry

• Professional-level suspension tuning for youth motocross racing

Advanced Öhlins STX Technology

STX 22 Cartridge System

Based on the technology used in Öhlins’ larger TTX racing cartridge kits, the STX 22 system delivers reliable and predictable damping performance designed specifically for small-displacement motocross bikes.

Low-Profile Top Cap Design

The cartridge is designed to sit very low above the fork tubes, allowing the forks to be mounted higher in the triple clamps. This enables riders to lower the bike slightly for improved ergonomics and control for smaller riders.

Accessible Adjusters

Click adjusters and the air breather are positioned at an angle beneath the handlebar, making suspension adjustments quick and easy between motos.

Consistent Damping Performance

The system delivers continuous damping response without harshness, maintaining predictable suspension behavior throughout the entire race.
