What is a progressive fork spring?

A progressive fork spring has a rate that changes as it compresses. It starts softer to absorb small bumps and then gets stiffer as it compresses further, providing better support during hard braking or cornering.

Why is the fork oil included important?

The fork oil is essential for damping the spring's movement and lubricating the fork internals. The specific viscosity and amount included in this kit are matched to the progressive springs for optimal performance.

What else might I need to install these fork springs?

You will typically need basic hand tools for fork disassembly and reassembly, along with a way to drain and refill the fork oil. Refer to your motorcycle's service manual for specific procedures and any specialized tools required.

Product Details

If you're looking to get a more comfortable and controlled ride out of your motorcycle, this Bitubo progressive fork spring kit with oil is a solid option. These springs are designed to change their stiffness as they compress, offering a softer initial feel for bumps and road imperfections, then firming up as you go deeper into the suspension travel. This progressive action helps your front end handle a wider range of riding conditions, from everyday commuting to spirited canyon carving, without the harshness of a spring that's too stiff or the wallowing of one that's too soft.

Bitubo is known for well-built suspension components, and this kit reflects that. The springs are made from strong materials to ensure they hold their shape and provide consistent performance over time. The kit also includes a liter of specialized fork oil, which is crucial for proper damping and lubrication within your forks. Using the correct oil viscosity and amount, as specified by Bitubo, is key to achieving the intended progressive action and overall improved feel from your front suspension.

When you're rebuilding or servicing your front forks, using a matched set like this from Bitubo takes the guesswork out of selecting springs and oil. It's a straightforward way to update your bike's handling characteristics and make your rides more enjoyable.
