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.

Let customers speak for us
Just a little bit stiff but overall I would buy them again and I would recommend them to everyone who is wanting a much better ride.
1993 Honda Nighthawk 750 transformed by these shocks. Left them in the middle setting for rebound and it was perfect. The stock shocks had very little rebound damping so you get thrown off the seat right after a bump.
These are like a magic carpet and really settled the bike.
Rides good.Has plenty of adjustment. CRF300l much more stable.Handles better.
Product arrived packaged well and was exactly what was advertised on their website. Would do business again with EPM
I’ve purchased Hyperpro products before and this purchase did not disappoint Would purchase from EPM again as well.
