What is a linear fork spring rate?

A linear spring rate means the force needed to compress the spring increases at a constant rate. This provides consistent support throughout the suspension's travel, unlike progressive springs which stiffen up more as they compress.

What is the benefit of upgrading fork springs?

Upgrading fork springs can lead to improved front-end stability, reduced brake dive, and better feedback from the road or track. It helps the suspension work more effectively for a more controlled ride.

Does this kit include everything needed for installation?

This kit includes the fork springs and 1 liter of fork oil. You may need additional tools and supplies, such as new fork seals and specific shop tools, depending on your motorcycle model. Refer to your service manual for installation details.

Product Details

This Bitubo MFORK Fork Springs Kit is designed to give your motorcycle's front suspension a more controlled and responsive feel. The kit includes linear fork springs with a rate of K=0.85, which is a popular choice for riders looking for improved stability and better feedback from the road or track. Along with the springs, you get a liter of specialized fork oil to ensure proper damping performance.

Bitubo is known for its well-built suspension components, and this kit is no exception. The linear spring rate means the force required to compress the spring increases steadily, providing consistent support throughout the suspension travel. This helps reduce front-end dive under braking and improves the bike's ability to hold its line in corners. The included fork oil is formulated to work with these springs, offering consistent damping characteristics across a range of temperatures.

Upgrading your fork springs is a significant step in tuning your motorcycle's handling. This kit offers a noticeable improvement in how your front end reacts to bumps and cornering forces, making for a more confident and enjoyable ride.
