⚙️ TECHNICAL SPECIFICATIONS & ADJUSTABILITY

🚀 REAL-WORLD PERFORMANCE

• 🛡️ Smooth Urban Commuting & Smart Economical Solution: By focusing on practical street riding needs and eliminating complex Rebound or Compression adjuster dials, the K-Alpha line offers an extremely economical price point. The internal hydraulic valving is tuned softly by KYB to rapidly absorb all feedback and shocks from potholes and manhole covers, delivering a plush stroke that vastly outperforms stock shocks while optimizing your budget.

• 💨 Mono Tube & Free-Piston Technology: Inherited from professional racetracks, the free-piston system inside the piggyback reservoir completely isolates the hydraulic fluid from the high-pressure compressed Nitrogen gas. Thus, 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 when riding fast.

• 🔧 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 luggage for a long trip, simply increase the spring compression to firmly support the rear end, preventing the shock from bottoming out.

• 📐 Valuable Length Adjuster Feature: Allows you to flexibly extend the shock body up to an additional 10mm (+10mm) from the standard 305mm (adjustable stroke from 305mm to 315mm). This feature helps you proactively adjust for a higher ground clearance or create a taller, sportier riding posture based on personal preference.

• 🎩 Elegant Stealth Black – Elevating Your Ride's Prestige: The strong pure black tone of the spring combined with an exquisite CNC reservoir brings a sophisticated mechanical beauty. This color scheme perfectly matches the aristocratic elegance of the SH150 Italia as well as the aggressive, angular stance of the Yamaha NVX 155, creating a commanding focal point under the chassis without being overly flashy.

🛠️ COMPATIBILITY & FITMENT

• ✅ Standard Spec Fitment (Plug and Play): With a load-bearing bottom Clevis mount, a standard top Eyelet mount, and a 305mm stroke length, this pair of shocks is an absolute direct bolt-on for both renowned twin-shock scooters: the Honda SH150 Italia and the Yamaha NVX 155 (both v1 and v2 generations). You simply secure them to the original frame and engine block mounts without needing custom load-bearing CNC brackets.

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