Introduction
This manual provides essential information for the installation, operation, and maintenance of your Ohlins TTX GP Rear Shock, model YA 468. Designed for 2015-2018 Yamaha R1, R1M, and 2016-2018 Yamaha MT-10 models, this shock absorber offers superior performance and adjustability compared to stock components.
The TTX GP features Ohlins' advanced twin-tube technology, incorporating improvements from MotoGP experience. Key enhancements include a new adjustment needle for more precise compression and rebound damping, a wider adjustment range, and a new main piston for improved traction and rider feel.

Safety Information
Always prioritize safety. Improper installation or adjustment of suspension components can lead to serious injury or damage. It is highly recommended that installation and initial setup be performed by a qualified motorcycle technician with experience in Ohlins products.
- Ensure the motorcycle is securely supported before beginning any work.
- Wear appropriate personal protective equipment (PPE), including eye protection and gloves.
- Refer to your motorcycle's service manual for specific torque specifications and procedures.
- Do not attempt to disassemble the shock absorber unless specifically instructed, as it contains high-pressure gas.
Setup and Installation
The Ohlins TTX GP Rear Shock (YA 468) is designed for OEM fitment in the stock location. However, precise setup is crucial for optimal performance.
Pre-Installation Checks:
- Verify that the shock model (YA 468) is correct for your motorcycle's year and model (2015-2018 Yamaha R1/R1M, 2016-2018 Yamaha MT-10).
- Inspect the shock for any signs of shipping damage.
- Ensure all included hardware is present.
Installation Steps (General):
- Safely lift and support the motorcycle to allow the rear wheel to hang freely.
- Remove the original rear shock absorber, carefully noting the orientation and any spacers.
- Install the Ohlins TTX GP shock in the reverse order of removal. Ensure all mounting bolts are clean and properly torqued to the manufacturer's specifications.
- Once installed, lower the motorcycle and perform initial sag measurements.
Note: Proper sag adjustment (static and rider sag) is fundamental for correct suspension operation. Consult an Ohlins service manual or a qualified technician for detailed sag setup procedures specific to your riding style and weight.
Operating and Adjustment
The TTX GP shock offers manual adjustable damping for both rebound and compression, allowing riders to fine-tune the suspension performance.
Damping Adjustments:
- Compression Damping: Typically located on the reservoir or lower body of the shock. Adjusts the resistance to the shock compressing. Turning the adjuster clockwise generally increases damping (firmer), counter-clockwise decreases damping (softer).
- Rebound Damping: Typically located at the bottom of the shock body. Adjusts the resistance to the shock extending after compression. Turning the adjuster clockwise generally increases damping (slower rebound), counter-clockwise decreases damping (faster rebound).
Important: Always make small, incremental adjustments (e.g., 1-2 clicks at a time) and test the changes. Keep a record of your settings. Refer to the Ohlins base settings provided with your shock for a starting point.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Ohlins TTX GP Rear Shock.
- Cleaning: Keep the shock absorber clean from dirt, dust, and road grime. Use mild soap and water, then rinse thoroughly. Avoid high-pressure washers directly on seals.
- Inspection: Periodically inspect the shock for any signs of oil leaks, damage to the shaft, spring, or adjusters. Check mounting bolts for tightness.
- Service Intervals: Ohlins recommends regular servicing by an authorized service center. Service intervals depend on usage (e.g., street riding vs. track use). Consult Ohlins documentation for specific recommendations.
- Storage: If storing the motorcycle for an extended period, ensure the shock is clean and dry.
Troubleshooting
This section addresses common issues you might encounter with your rear shock.
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive bottoming out | Insufficient spring preload, too little compression damping, incorrect spring rate. | Increase spring preload, increase compression damping, consider a stiffer spring. |
| Harsh ride / Lack of compliance | Too much compression damping, too much spring preload, incorrect spring rate. | Decrease compression damping, decrease spring preload, consider a softer spring. |
| Rear end pogoing / Bouncing | Too little rebound damping. | Increase rebound damping. |
| Rear end packing up / Not extending fully | Too much rebound damping. | Decrease rebound damping. |
| Oil leakage | Damaged seals, internal component failure. | Contact an authorized Ohlins service center for inspection and repair. Do not ride with a leaking shock. |
For persistent issues or complex adjustments, it is always best to consult an authorized Ohlins service center or a professional suspension tuner.
