Setup and Installation
Installation of the Ohlins STX46 Street Rear Shock requires specialized tools and technical knowledge. It is highly recommended that installation be performed by a qualified motorcycle technician or an authorized Ohlins service center. Improper installation can lead to reduced performance, damage to the motorcycle, or personal injury.
General Guidelines (for professional reference):
- Preparation: Ensure the motorcycle is securely supported on a stand. Remove the existing rear shock absorber according to the motorcycle manufacturer's service manual.
- Mounting: Install the Ohlins STX46 shock absorber, ensuring all mounting bolts are correctly torqued to the specifications provided in the motorcycle's service manual.
- Clearance Check: Verify that there is adequate clearance around the shock absorber and its components throughout the full range of suspension travel.
- Initial Settings: Apply the recommended initial settings for preload and damping as specified in the Ohlins documentation (not provided here, typically found in a separate product-specific manual).
- Final Inspection: Double-check all fasteners and connections before operating the motorcycle.
Operating and Adjustment
The Ohlins STX46 shock absorber is designed for optimal performance with minimal user intervention after professional installation and initial setup. The primary user-adjustable feature is the rebound damping.
Rebound Damping Adjustment:
- Purpose: Rebound damping controls the speed at which the shock absorber extends after being compressed. Proper rebound damping prevents the wheel from "bouncing" after hitting a bump and helps maintain tire contact with the road.
- Location: The rebound damping adjuster wheel is located on the end-eye or the reservoir of the shock absorber.
- Adjustment:
- Turning the adjuster clockwise typically increases rebound damping (slower extension).
- Turning the adjuster counter-clockwise typically decreases rebound damping (faster extension).
- Procedure: Make small adjustments (e.g., 1-2 clicks at a time) and test the motorcycle's handling in a safe environment. Note your starting settings to easily revert if needed. Consult an Ohlins service manual or a qualified technician for specific recommendations for your riding style and weight.
Note: Other adjustments like spring preload or compression damping (if applicable to specific variants) should ideally be performed by a professional to ensure proper balance and safety.
Maintenance
Regular maintenance is crucial for the longevity and optimal performance of your Ohlins STX46 Street Rear Shock. While Ohlins products are built for durability, periodic checks and professional servicing are recommended.
- Cleaning: Keep the shock absorber clean from dirt, dust, and road grime. Use mild soap and water, avoiding harsh chemicals that could damage seals or finishes.
- Inspection: Periodically inspect the shock for any signs of oil leaks, damage to the shaft, spring, or mounting points. Check for loose fasteners.
- Professional Servicing: Ohlins recommends periodic servicing by an authorized Ohlins service center. This typically involves replacing seals, oil, and checking internal components to maintain peak performance. Refer to the specific Ohlins service schedule for your product, usually found in a dedicated service manual.
- Storage: If storing the motorcycle for an extended period, ensure the shock is clean and stored in a dry environment.
Troubleshooting
This section addresses common issues that may arise with your rear shock. For complex problems, always consult a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive Bouncing / Lack of Control | Insufficient rebound damping. | Increase rebound damping (turn adjuster clockwise). |
| Harsh Ride / Slow Recovery | Excessive rebound damping. | Decrease rebound damping (turn adjuster counter-clockwise). |
| Oil Leakage | Damaged seals or internal components. | Stop riding immediately. Seek professional inspection and repair by an authorized Ohlins service center. |
| Unusual Noises (e.g., knocking, squeaking) | Loose mounting bolts, internal wear, or component interference. | Check mounting bolts for proper torque. If noise persists, seek professional inspection. |
