What is a linear fork spring rate?

A linear spring rate means that for every inch the spring is compressed, the force required to compress it increases by the same amount. This provides a predictable and consistent feel throughout the suspension's travel, unlike progressive springs which get stiffer as they compress.

What type of riding is this fork spring kit best suited for?

This kit is well-suited for sport riding, track days, or any rider who prefers a more direct and responsive feel from their front suspension. The linear rate offers improved feedback during hard braking and cornering.

Does this kit include everything needed for installation?

The kit includes the linear fork springs and 1 liter of specialized fork oil. You will need to consult your motorcycle's service manual for specific installation procedures and any additional tools or fluids that may be required.

Product Details

This is the Bitubo MFORK Fork Springs Kit, featuring linear springs with a K-value of 0.85. This kit is designed to replace your motorcycle's stock fork springs, offering an improved damping response and a more stable feel during cornering and braking. The linear spring rate means the force required to compress the spring increases at a constant rate, providing predictable performance across a wider range of riding conditions. This kit also includes 1 liter of specialized fork oil, ensuring you have the necessary fluids for installation.

Bitubo is known for well-built suspension components, and this kit is no exception. The springs are made from strong, high-tensile steel to maintain their rate over time and resist fatigue. The included fork oil is formulated to work with these springs, offering consistent damping characteristics and good heat resistance. By upgrading to these springs, you can expect a more planted feel from your front end, especially when pushing the bike harder or riding on varied road surfaces. This upgrade is a solid option for riders looking to fine-tune their motorcycle's handling.
