What is a linear fork spring?

A linear fork spring has a constant spring rate, meaning the force required to compress it increases at a steady rate. This provides consistent damping characteristics throughout the suspension's travel, unlike progressive springs which get stiffer as they compress.

Why is the included fork oil important?

Fork oil acts as a damping fluid and lubricant within your suspension. Using the correct weight and amount of oil, as provided in this kit, is essential for your forks to function as intended and achieve the desired ride characteristics.

What kind of bikes is this kit typically for?

While fitment must be confirmed, a K=0.90 spring rate is commonly used in sportbikes and performance motorcycles. It's designed for riders looking for improved handling and a more controlled feel compared to stock suspension.

Product Details

Bitubo Suspension is known for making well-built suspension components, and this MFORK Fork Springs Kit is a great example of their work. If you're looking to get a more controlled and responsive feel from your motorcycle's front end, this kit is designed to help. It replaces your stock fork springs with linear rate springs that offer a consistent rate of resistance throughout their travel, which can lead to improved stability and better feedback from the road or track.

This kit comes with linear springs rated at K=0.90, a common rate for many sportbikes and performance-oriented motorcycles, offering a noticeable improvement over softer stock springs without being overly stiff. Along with the springs, Bitubo includes a liter of their specialized fork oil. Using the correct weight and amount of oil is crucial for proper fork function, and having it included in the kit simplifies the installation process. This combination of well-made springs and appropriate fork oil helps your suspension work more effectively, especially during hard braking and cornering.

When installing fork springs, it's important to follow the manufacturer's recommended procedures for disassembly and reassembly of your forks. This kit is a solid option for riders who want to fine-tune their bike's handling and feel more connected to their machine.
