What is a linear fork spring rate (K=0.90)?

A linear spring rate means the force required to compress the spring increases at a constant rate. A K=0.90 rate offers a firmer feel than stock springs on many bikes, providing more control during aggressive riding or when carrying extra weight.

What is included in this kit?

This kit includes a pair of linear fork springs with a K=0.90 rate and one liter of Bitubo brand fork oil. You will need to reuse your existing fork internals and seals.

Do I need any special tools to install these fork springs?

Installation typically requires basic motorcycle tools, including wrenches, sockets, and a way to safely support the front of the motorcycle. Refer to the manufacturer's installation instructions for specific tool requirements and procedures.

Product Details

This is the Bitubo MFORK Fork Springs Kit, designed to give your motorcycle's front suspension a more controlled and responsive feel. It includes linear fork springs with a K=0.90 rate and a liter of specialized fork oil. Upgrading your fork springs is a common way to tune your bike's handling to better suit your riding style or to compensate for added weight, like a heavier rider or luggage.

The linear spring rate means the resistance increases steadily as the suspension compresses, offering predictable performance during braking and cornering. This kit comes with Bitubo's own fork oil, formulated to work with these springs for optimal damping characteristics. Bitubo is known for well-built suspension components, and this kit is a solid option for riders looking for improved front-end stability and feedback from their machine.

When installing new fork springs, it's important to follow the manufacturer's instructions carefully. You'll typically need to drain the old oil, replace the springs, and then refill with the correct amount and type of new oil. This kit simplifies the process by including both the springs and the necessary oil.
