⚙️ TECHNICAL SPECIFICATIONS & ADJUSTABILITY
🚀 REAL-WORLD PERFORMANCE
-
🛡️ Smooth Urban Commuting & Maximum Cost Savings: By focusing entirely on real-world urban riding and eliminating complex Rebound or Compression adjuster dials, the K-Alpha provides you with an extremely economical upgrade solution. The internal hydraulic valving is softly tuned by KYB to rapidly absorb all shocks from potholes and manhole covers, delivering a plush stroke that vastly outperforms stock shocks.
-
🔥 Radiant Racing Red – A Captivating, Edgy Accent: In stark contrast to the minimalist black colorway, the red spring version brings an energetic and deeply sporty appearance. The vibrant red paint illuminates the rear undercarriage, creating a perfect mechanical contrast with the engine block, making your beloved ride look powerful, standout, and eye-catching as you cruise down the street.
-
💨 Mono Tube & Free-Piston Technology: This is a premium technology inherited directly from racing blueprints. The free-piston system inside the piggyback reservoir completely isolates the hydraulic fluid from the high-pressure compressed Nitrogen gas. As a result, the damping oil does not aerate (foam) or overheat during continuous operation, keeping the rear wheel firmly planted and completely eliminating rear-end wobbling or floating.
-
🔧 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 a smooth stroke. When carrying a passenger or a large amount of touring luggage, simply increase the spring compression to firmly support the rear end without bottoming out the stroke travel.
-
📐 Valuable Length Adjuster Feature: Allows you to flexibly extend the shock body up to an additional 10mm (+10mm) from the standard 305mm. This feature helps you proactively adjust for a higher ground clearance or create a taller, more aerodynamic, and sportier riding posture based on personal preference.
🛠️ COMPATIBILITY & FITMENT
To completely eliminate your biggest concern when buying online—the fear of rubbing or improper fitment—Monkey89 has rigorously verified the geometric compatibility of SKU RG210042:
-
✅ Standard Spec Fitment (Plug and Play): The product features a load-bearing bottom Clevis mount and a top Eyelet mount that perfectly match the original bolt specifications of both renowned twin-shock scooters: the Honda SH150 Italia and the Yamaha NVX 155 (including both V1 and V2 generations). The standard 305mm height ensures optimal geometric balance for the rear suspension; you simply bolt it directly onto the scooter without needing custom load-bearing CNC brackets.
-
📍 Installation Position: Direct replacement for the symmetrical rear twin shock absorbers on the motorcycle.
