What is the spring rate (K=0.90) and what does it do?

The K=0.90 indicates the spring rate, which measures how stiff the spring is. A higher number generally means a stiffer spring. This specific rate is chosen to provide improved support during braking and acceleration, and to reduce fork dive.

Does this kit include everything needed to install the fork springs?

This kit includes the fork springs and 1 liter of fork oil. You may need additional tools for disassembling your forks and potentially other fluids or seals depending on your specific fork model and service history.

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

This kit is designed for riders who want improved front-end control and stability, particularly during performance riding such as track days or spirited street riding. The K=0.90 rate offers a noticeable change from stock for a more planted feel.

Product Details

Bitubo Suspension is known for making well-built suspension components for performance riding. This MFORK Fork Springs Kit is designed to give your bike's front end a more controlled feel, especially when you're pushing it on the track or on spirited rides. The kit includes springs with a K=0.90 spring rate, which is a specific stiffness chosen to work with cartridge-style forks. This rate aims to improve how the front suspension handles compression and rebound, giving you a more stable platform through corners and over bumps.

This kit comes with 1 liter of fork oil, which is the correct amount for many cartridge fork applications, simplifying your service. The springs themselves are made to fit specific cartridge internals, ensuring a direct replacement for your stock springs. By changing the spring rate, you can significantly alter how your bike reacts to rider input and terrain. A stiffer spring rate, like the K=0.90 here, generally helps prevent excessive fork dive under braking and can improve support during acceleration, leading to a more predictable ride.
