Bitubo MFORK Fork Springs Kit Progressive (K=0.75-0.85) + 1 Lt. Oil

These Bitubo progressive fork springs feature a spring rate that changes from K=0.75 to K=0.85. This means the spring gets stiffer as it compresses, offering a more controlled feel through the entire range of suspension travel. Unlike a linear spring that has a constant rate, a progressive spring can provide a softer initial response for comfort and then ramp up to handle harder impacts or cornering forces.

The kit includes 1 liter of specialized fork oil, which is crucial for proper suspension function. Using the correct oil viscosity and amount ensures your forks operate smoothly and dissipate heat effectively. Bitubo is known for its well-built suspension components, and this kit is designed to give your motorcycle a more responsive and stable ride, especially when pushing the limits on winding roads or during spirited riding.
