About This Product

This Bitubo MX fork spring kit is designed for riders who need a slightly firmer front end than the standard setup. With a K 0.75 spring rate, these linear springs provide consistent support throughout the fork's travel. They are made from high-quality chrome silicone alloy steel and measure 360mm in length. This kit is sold as a pair and comes complete with fork oil and installation instructions. Note that these are only compatible with Bitubo fork cartridges and won't work with stock components. Fitment includes 2013 to 2017 Breakout, 2018 to 2024 Street Bob, and 2014 to 2016 FLT Touring models such as the Road Glide, Street Glide, and Ultra Limited when fitted with Bitubo cartridges.

Manufacturer part number: MX121.
