At MX1, we make your YZ/YZF suspension the best it can be. Through countless hours of testing, we have come up with settings that not only improve suspension performance, it will turn better too. MXA's John Parry raced a YZF 450 with MX1 suspension at the World Vet Championship and absolutely raved about how good it worked. A week later he called after racing a stocker and said "After racing your bike, I can't even ride a stock one anymore. The difference is amazing."

Years: 2005-2010
Displacement: 125/250/450

Fork Revalve - Internals are totally reworked to stay up in the stroke, yet remain plush with great bottoming resistance. Rebound damping is matched to spring rate and then filled with highest quality oil. $195 + oil + springs (if req.)

Shock Revalve - Compression and rebound is matched to your type of riding and skill level. A special bypass valve is installed to help keep the rear of the bike up in the stroke without using an overly stiff spring or valving. This is the key to improved turning capabilities. $245 + oil + spring (if req.)
