Properly adjusting your front fork suspension can greatly improve your motorcycle’s handling and overall performance. Here are some expert tips to help you get the most out of your front fork suspension:
1. Set Sag Correctly
Setting sag is crucial for obtaining optimal suspension performance. Sag is the amount of suspension travel used when the rider is positioned on the bike. To set sag correctly, follow these steps:
- Put the motorcycle in its normal riding position with all the rider’s gear on.
- Measure and record the distance between a fixed point on the bike and the front axle.
- Place a zip tie around one of the fork legs a few inches above the bottom and push it down until it touches the seal.
- Have someone steady the bike or use a stand to support it. Remember to keep your weight off the bike.
- With the zip tie in place, carefully climb onto the bike in your normal riding position.
- Have the helper measure the distance between the zip tie and the fixed point on the bike. This measurement is the “rider sag”.
- The rider sag should ideally be between 30-40% of the total travel of the front fork suspension.
- If the sag is not within the desired range, adjust the preload by either tightening or loosening the preload adjusters on your forks.
2. Fine-tune Compression and Rebound Damping
Compression damping controls how the suspension compresses when hitting a bump, while rebound damping controls how the suspension rebounds after being compressed. To fine-tune these settings:
- Start with the damping adjusters set in the middle of their range.
- Go for a ride on a typical road or track that you’ll be riding on.
- Pay attention to how your motorcycle feels over different types of bumps and corners.
