Progressive 420 series single shocks are available for: BMW, Honda, Kawasaki, Suzuki, and Yamaha motorcycles. The unique internal bladder design of the 420 Series allows for easy shock installation without the need to find a location to mount the reservoir. The internal bladder is gas charged with nitrogen to give superior fade-free damping. Velocity sensitive, multi-stage valving for a consistent, controlled ride. Our famous Progressive Rate Spring gives superior ride and handling over a variety of surfaces. External 5-position rebound damping adjustment allows you to dial-in the ride you want. The shock shaft is made from 14mm chromoly steel, hard chromed for durability and smooth operation. Spring pre-load is adjusted with a threaded collar. Shocks are completely rebuildable.
