Upgrade the riding experience and the road behaviour of the CF MOTO NK 400 with the YSS MZ456 shock absorber. Designed for riders looking for top performance, stability and precision, the MZ456 is the ideal choice for replacing the factory suspension, giving full control on every ride. Features: Top Line series: A high-performance nitrogen shock absorber, built to a high-strength, high-precision specification. Rebound Damping: It has a 30-click adjuster so you can set the shock's return speed to suit the road surface and your riding style. Threaded Spring Preload: It allows micrometric adjustment of the spring's stiffness, ensuring the motorcycle's geometry is right for the load (rider, pillion, luggage). Quality build: An aircraft-type aluminium body (CNC machined) for low weight, maximum heat dissipation and top-class looks. A large piston (45mm): It guarantees steady performance even under hard use, preventing the suspension from fading.
