🏍️ GENUINE KYB BLACK REAR SHOCKS FOR HONDA SH300 / SH350 / YAMAHA FORZA 300 (390MM + 10MM) K-ALPHA JAPANESE TECHNOLOGY
Owning a powerful, large-displacement scooter like the Honda SH300, SH350i, or Forza 300 is a point of pride. However, does the heavy chassis combined with overly stiff stock suspension frequently deliver back-breaking "clunks" when crossing speed bumps?
Not to mention, when you ride at high speeds or carry a passenger, the rear end easily wobbles and floats, exposing highly dangerous mechanical instability. To re-establish maximum smoothness and safety for these maxi-scooters, Monkey89 introduces a high-performance upgrade component: KYB K-Alpha Black Rear Shocks (390mm). This pinnacle Mono-tube technology solution helps your scooter glide through the city like velvet, maintains solid balance, and provides absolute peace of mind.

⚙️ TECHNICAL SPECIFICATIONS & ADJUSTABILITY
🚀 REAL-WORLD PERFORMANCE
-
🛡️ Smooth Urban Commuting & Cost Optimization: For inner-city commuting needs, equipping complex Rebound or Compression adjuster dials is often unnecessary and overly complicated. The K-Alpha line eliminates these details to focus entirely on a smooth urban hydraulic valving profile. The shock excellently absorbs impacts from potholes and speed bumps, absolutely protecting your spine at a highly economical price, making it a perfect replacement for technologically inferior stock shocks.
-
💨 Mono Tube & Free-Piston Technology: This is pinnacle technology inherited directly from racing mechanical 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 a heavy chassis, keeping the rear wheel firmly planted and eliminating wobbling or rear-end 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 heavy touring luggage, simply increase the spring compression to keep the ground clearance balanced and solid, without worrying about bottoming out the stroke.
-
📐 Valuable Length Adjuster Feature: You can freely extend the shock body from 0 to 10mm (+10mm) compared to the standard 390mm specification. This feature helps you proactively realign the scooter's center of gravity, creating a taller, more commanding, and aerodynamic riding posture based on personal preference.
-
🎩 Elegant Stealth Black – Luxurious Mechanical Prestige: The mysterious black tone of the steel spring paired with sharp CNC aluminum mounts delivers a rugged, powerful aesthetic. This color scheme flawlessly matches the elegant demeanor of the SH300/350 and the angular stance of the Forza 300, creating a commanding focal point under the rear chassis without being 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 Maxi-Scooters including: Honda SH300i, Honda SH350i (all domestic and imported generations), and Yamaha Forza 300. The standard 390mm height ensures optimal balance for the chassis system; you simply secure them directly to the stock bolts very quickly.
-
✂️ ABSOLUTELY NO FAIRING MODIFICATIONS REQUIRED: This is a massive plus for SKU RG2100054. Because the original structure of luxury scooters like the SH350i, SH300i, or Forza 300 was designed by the manufacturer with an incredibly spacious rear wheel well to accommodate piggyback shocks. When you upgrade to these 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 the scooter's sharp, original aesthetic integrity.
-
📍 Installation Position: Direct replacement for the symmetrical rear twin shock absorbers on the motorcycle.
