MU362 Reservoir Shock
Elite Compact Performance: YSS MU362 Bottom Piggyback Mono Shock
Want top-tier racing suspension for your small-displacement streetfighter, mini-moto, or lightweight naked bike? The YSS MU362 Series brings heavy-hitting, premium track technology into a compact package. Engineered for high-performance pocket rockets and lightweight monoshock bikes (like the Honda Grom, Kawasaki Z125, and Benelli TNT 125), the MU362 features YSS's signature bottom-mounted piggyback reservoir to deliver unbeatable chassis control.
By positioning the nitrogen gas reservoir at the bottom of the shock, the MU362 significantly increases oil capacity in tight workspaces where standard top-mounted reservoirs won't fit. This isolated gas-and-oil configuration prevents oil foaming (cavitation) and heat fade, keeping your rear tire firmly glued to the pavement whether you are carving city streets, attacking tight go-kart tracks, or commuting.
Why Choose the YSS MU362 Monoshock?
- Integrated Bottom Reservoir: The separated nitrogen gas chamber increases cooling efficiency and oil volume, ensuring your damping remains perfectly consistent even during aggressive, continuous riding.
- Precision Compression Tuning: Fine-tune how your shock reacts to fast bumps and rider weight transitions. Depending on your model, this features advanced compression damping control (including High and Low-Speed compression options on select applications).
- Tactile Rebound Adjustability: Features up to 30 clicks of rebound adjustment. Easily dial in the suspension’s return speed to eliminate bouncy "pogo" effects and keep the chassis stable during quick directional changes.
- Threaded Spring Preload: Ditch the soft factory sag. Adjust the threaded collar using the included tool to set the perfect spring tension based on your riding gear and body weight.
- Billet-Machined Construction: CNC-machined from high-strength aircraft-grade aluminum to minimize weight while offering massive durability and a high-end, premium aesthetic.

Combo Kit for 2025 NC750X DCT completely changed the bike. At 245 pounds the stock set up just wasn’t right. Pre-load set at 5 out of 7 and the sag is perfect. Speed bumps don’t hurt anymore. Brake dive has been greatly reduced. Best bang for the buck one could ever hope to find. Highly recommend this upgrade.
Awesome fast, responsive, and happy that there's a reputable shop for my rebuilds!
The process was easy, the price was fair, and the bike rides like new with a rebuilt shock. ESA still works and there are still no leaks a month in.
As promised, fit BMWF800ST Perfectly. If your budget allows I would advise upgrading to fully remote adjustment. On my BMW it is impossible to adjust shock W/O moving under seat fuel tank.
Great upgrade to the V7 . The bike is planted on the road. Cornering is smooth and predictable. Great customer service and support. Fast shipping to my remote location in Canada.
Very satisfied with the product and customer service that I received from EPM Performance. Highly Recommended / Buy With Confidence
The Hyperpro damper mounting kit fit and finish was Fantastic on my 05 GS and the price was right. It worked perfectly with my OEM Damper. Thank You EPM Performance for the Excellent Communication and Very Fast well packaged shipping. Dealing with your company was really a breath of fresh air! Thank You
Easy to order, good updates on delivery and the kit works great.
My weight with clothes, helmet, boots, and backpack is 205 lbs. With the stock fork springs my race sag was 6.8”. The front end would break loose every ride in dirt/gravel, I’m talking scary not cool. With the stock shock spring my race sag was 7”and the rear would bottom out frequently. With the fork spring kit installed my race sag is now 2.0 “. The front end feels planted now and I am using much lower settings for rebound and compression. With the new shock spring, my race sag is now 2.4”with preload set a 7. The rear hasn’t bottomed out yet, I don’t catch big air so YMMV. Installation instructions were great and the kit was an easy install. My bike is a 2025 KTM 390 Enduro R. I would highly recommend this kit to anyone with that bike. It makes the bike fun instead of scary and annoying.
