STX 36 Race-Derived Suspension Technology
At the heart of the Öhlins STX 36 is a 36 mm high-flow piston operating within a monotube hydraulic body. The high-pressure gas design separates hydraulic oil from nitrogen, reducing cavitation and maintaining stable damping characteristics even under aggressive riding conditions.
Compared to OEM suspension, the STX 36 offers:
- Improved suspension response
- Increased rear tire grip
- Superior bump absorption
- Enhanced cornering stability
- Reduced suspension fade
- More consistent damping under heavy use
- Improved rider feedback
The advanced hydraulic design keeps the rear wheel planted, improving both performance and rider confidence on demanding roads.
External Piggyback Reservoir
The integrated piggyback reservoir increases oil capacity and improves thermal stability, allowing the suspension to maintain consistent performance during prolonged spirited riding.
Benefits include:
- Increased oil volume
- Better heat dissipation
- Reduced damping fade
- Improved hydraulic consistency
- Superior performance during aggressive riding
- Enhanced suspension longevity
This configuration is ideal for riders who regularly push the limits of the XR1200 chassis.
Adjustable Rebound Damping
External rebound adjustment allows precise control over suspension extension speed following compression.
Proper rebound tuning improves:
- Corner exit traction
- High-speed stability
- Suspension recovery over uneven pavement
- Chassis composure
- Rider confidence
- Overall handling precision
The easily accessible adjuster enables quick suspension tuning to match rider preference and road conditions.
Adjustable Compression Damping
Independent compression adjustment allows the rider to tailor suspension firmness during bump absorption.
Compression tuning optimizes:
- Brake stability
- Impact absorption
- Chassis support
- Cornering precision
- Passenger comfort
- Ride quality over rough pavement
Together with rebound adjustment, compression tuning provides a highly customizable suspension setup.
Adjustable Ride Height
Integrated ride height adjustment allows chassis geometry to be fine-tuned without affecting spring preload.
Benefits include:
- Faster steering response
- Increased lean angle clearance
- Improved weight distribution
- Enhanced agility
- Customized riding position
- Optimized handling characteristics
This feature is particularly valuable for riders seeking maximum performance from the XR1200 platform.
Adjustable Spring Preload
Threaded spring preload adjustment allows proper suspension sag to be established for rider weight and intended use.
Correct preload adjustment contributes to:
- Balanced chassis geometry
- Improved steering feel
- Better braking stability
- Increased cornering confidence
- Enhanced traction
- Maximum suspension effectiveness
Proper setup ensures the suspension operates within its designed travel range for optimum performance.
