Learn how to set up the 49mm GRIP ST fork cartridge on your Harley-Davidson Touring. Step-by-step installation and tuning advice for a better ride.
Quick Answer
Set up your Harley-Davidson Touring with the 49mm GRIP ST fork cartridge by following a careful installation process, then tune compression and rebound using the tool-free top caps to match your riding style.
Why the GRIP ST Stands Out
The GRIP ST is a drop-in open bath cartridge kit designed for Harley-Davidson Touring models. It replaces the stock fork internals with a performance-oriented cartridge that offers three-position compression and rebound adjustments on the top caps. This means you can fine-tune your suspension without carrying any tools, making it easy to adapt to different riding conditions.
Trade-Offs to Consider
While the GRIP ST significantly improves handling and adjustability, it requires a full fork disassembly for installation. If you are not comfortable working on your forks, professional installation is recommended. Also, the cartridge is tuned for performance, so it may feel firmer than stock for casual cruising riders.
Step-by-Step Setup Process
- Prepare Your Bike: Secure the motorcycle on a lift or stand so the front wheel is off the ground. Remove the front wheel and fender to access the fork tubes. Loosen the triple clamp bolts gradually to avoid stress. Check that the bike is stable before loosening any bolts.
- Remove the Stock Fork Internals: Carefully disassemble the fork tubes, keeping track of all components and their order. Drain the old fork oil and inspect the tubes for wear or damage. Clean all parts thoroughly. Use a clean work area to avoid contaminating the new cartridge.
- Install the GRIP ST Cartridge: Insert the GRIP ST cartridge into the fork tube following the manufacturer's instructions. Ensure the cartridge sits correctly and is fully seated. Reassemble the fork with the recommended oil level and torque specs. Double-check that the cartridge is oriented correctly before reassembly.
- Reinstall the Forks and Set Sag: Reinstall the fork tubes and torque the triple clamps to spec. Set the sag according to your weight and riding style, using the ride height options if available. This step is critical for proper handling. A sag measurement that is too high or low will affect both comfort and cornering.
- Adjust Compression and Rebound: Use the top caps to set compression and rebound to your preferred position. Start with a middle setting and test ride. Adjust one click at a time until the fork feels balanced and controlled. Make small adjustments and test ride after each change for best results.
