SX AND MX SHOCKS EXPLAINED
I'm a pretty fast rider, is this too stiff for me?
Most likely. SX forks and shocks were designed in collaboration with Josh Hill to be the stiffest setup to handle the biggest hits. We recommend SX tune for pro-level riders only.
What is the main difference between SX and MX R46 shocks?
SX tuned shocks are overall way stiffer. They have firmer damping, stiffer bottom out bumper and heavier spring.
Ultimate Suspension Tuning
Fully tunable valving on compression and rebound, with spring rates matched to rider weight and riding type. Adapt your suspension setup for different types of rides, enhancing overall riding experience.
TUNING WITHOUT
COMPROMISE
LSC (Low Speed Compression)
