Bitubo JBHV1 Pressurized Cartridge Adj.: Spring Preload, Rebound, Comp., w/o Oil, Red Ring

The Bitubo JBHV1 Pressurized Cartridge Kit is built around a 30mm piston, a notable design choice that allows for precise control over suspension damping. This kit is designed to replace the stock internals in your front forks, offering a significant upgrade in performance and adjustability. It’s a substantial investment for riders looking to fine-tune their motorcycle’s handling for a more connected feel to the road or track.

This kit allows for independent adjustment of spring preload, rebound damping, and compression damping. The spring preload is adjusted via threaded collars, letting you set the initial sag of your suspension to match your riding style and load. Rebound adjustment controls how quickly the fork extends after being compressed, preventing harshness and improving stability over bumps. Compression adjustment manages how the fork compresses under load, crucial for maintaining tire contact and control during braking and cornering. The pressurized design helps prevent cavitation, ensuring consistent damping performance even under demanding conditions.

Included in this kit are the cartridges themselves, ready for installation into your existing fork lowers. While this specific model comes without oil, it’s designed to work with the appropriate fork oil weight and volume specified by Bitubo or your motorcycle’s service manual. Proper installation by a qualified technician is recommended to ensure optimal performance and safety, as it involves disassembling and reassembling your front forks.
