MX456 Reservoir Shock

Premium Track & Trail Control: YSS MX456 Shock Absorber

Looking to unleash the true performance potential of your sport bike, adventure tourer, or off-road machine? The YSS MX456 Series is a top-tier, large-capacity monoshock engineered to handle extreme riding conditions. Positioned as a flagship model in YSS's Mono Line, the MX456 replaces your underwhelming stock rear suspension with race-proven, heavy-duty damping technology that delivers incredible chassis stability, relentless traction, and precise wheel control.

Built around a massive 45mm piston and a rugged 16mm shaft, the MX456 is designed to withstand immense structural loads without flexing or fading. Equipped with an external reservoir , this shock offers vastly superior oil volume and heat dissipation, ensuring fade-free performance whether you are hammering down technical trails, burning laps on a track day, or touring fully loaded.

Why Choose the YSS MX456 Monoshock?

• Advanced Compression Adjustability: Features precision compression damping adjustment (with up to 30 clicks). Higher-tier variations offer independent High and Low-Speed compression clickers, allowing you to perfectly isolate high-speed hits (like potholes and square edges) from low-speed chassis movements (like braking and cornering loads).
• Tactile Rebound Tuning: Easily dial in your rear-wheel recovery speed with a 30-click rebound adjustment. This prevents the rear end from pogo-sticking out of corners or packing down over repetitive, high-speed bumps.
• Oversized Big-Body Build: The heavy-duty 45mm piston moves more oil per millimeter of stroke than standard 36mm shocks, yielding immediate, ultra-plush damping responses. The 16mm shaft ensures maximum rigidity under harsh bottoming forces.
• Customizable Preload & Ride Height: Features a secure, threaded spring preload collar with a side locking bolt. Select applications also offer integrated ride height adjustment (up to +10mm) to sharpen your steering geometry and personalize your stance.
