🏍️ GENUINE KYB BLACK REAR SHOCKS FOR YAMAHA XMAX 300 (350MM + 10MM) K-ALPHA JAPANESE TECHNOLOGY

As the owner of a powerful Maxi-Scooter like the Yamaha Xmax 300, you undoubtedly demand a commanding and correspondingly smooth riding experience. However, given the scooter's heavy weight, the stock suspension system often reveals its weaknesses over time through annoying "clunks" when hitting potholes, or by causing the rear end to float and wobble whenever you ride fast or carry a passenger and luggage.

Deeply understanding this pain point, Monkey89 proudly presents the perfect mechanical upgrade solution that maintains the scooter's standard geometric stance: KYB K-Alpha Black Rear Shocks (350mm). This premium Aftermarket piggyback shock from Japan, featuring an elegant Stealth Black colorway, helps your beloved ride glide through the city with absolute plushness and rock-solid stability on every daily journey.

💡 Fitment Note: Please use the compatibility search tool directly on the Monkey89 website—simply enter your motorcycle's make, model, and year to get instant results.

🚀 REAL-WORLD PERFORMANCE

  • 🛡️ Smooth Urban Commuting & Smart Economical Solution: By focusing maximally on actual daily commuting needs and eliminating complex Rebound or Compression hydraulic adjuster dials, the K-Alpha line offers an extremely economical upgrade solution. The internal hydraulic valving is softly tuned by KYB to absorb all impact forces from manhole covers and potholes, completely erasing spine-jarring clunks and delivering a plush stroke that vastly outperforms technologically inferior stock shocks.

  • 💨 Free-Piston System & Mono Tube: This is pinnacle technology inherited directly from racing blueprints. The free-piston system inside the piggyback reservoir completely isolates the damping oil from the high-pressure compressed Nitrogen gas. As a result, the oil does not aerate (foam) or overheat even when supporting the heavy Xmax chassis, keeping the rear wheel firmly planted and completely eliminating rear-end wobbling or floating when you ride at high speeds.

  • 🔧 Spring Preload Adjustment: Allows you to proactively manage the stiffness/softness of the spring to suit the actual payload. For gentle solo city cruising, loosen the spring for maximum plushness. When carrying a passenger or a large amount of luggage in the trunk for a long trip, simply increase the spring compression to firmly support the rear end without bottoming out the stroke travel.

  • 📐 Valuable Length Adjuster Feature: You can freely extend the shock body from 0 to 10mm (+10mm) compared to the standard 350mm specification (from 350mm up to a maximum of 360mm). This feature helps you proactively adjust for a higher ground clearance or slightly raise the rear end for a sleeker, sportier stance based on personal preference.

  • 🎩 Elegant Stealth Black – Maintaining Aristocratic Refinement: The mysterious black tone of the steel spring combined with sharp CNC aluminum mounts creates a commanding focal point under the rear chassis. This color scheme perfectly matches the inherent luxurious and elegant design language of the Yamaha Xmax 300, delivering a rugged mechanical beauty without being overly flashy.

🛠️ COMPATIBILITY & FITMENT

  • ✅ Standard Spec Fitment (Plug and Play): The product features a load-bearing bottom Clevis mount that tightly hugs the engine block and a top Eyelet mount that perfectly matches the original bolt specifications of the Yamaha Xmax 300. The standard 350mm height is an absolute match with the factory shock specifications, ensuring the manufacturer's original operational geometry and stance are maintained.

  • ✂️ ABSOLUTELY NO FAIRING MODIFICATIONS REQUIRED: This is a superior advantage when installing these shocks on the Xmax 300. Because the original structure of the Yamaha Xmax 300 is already equipped with a twin shock system featuring rear-facing piggyback reservoirs, the rear wheel well space is incredibly spacious. When you upgrade to these standard 350mm KYB K-Alpha shocks, the entire shock body and piggyback reservoir will perfectly fit into the existing space. You can easily install them yourself without trimming or cutting any plastic fairing parts, maintaining 100% of your beloved scooter's pristine original aesthetics.

  • 📍 Installation Position: Direct replacement for the symmetrical rear twin shock absorbers on the motorcycle.
