KYB K-ALPHA SERIES PIGGYBACK REAR TWIN SHOCKS (365MM+10MM) FOR HONDA SH150/160 VN / PCX 160 / DATBIKE QUANTUM S1 - MATTE BLACK
Hello Boss! When operating maxi-scooters or premium electric motorcycles such as the Honda SH150/160 VN, PCX 160, or the modern Datbike Quantum S1, stock rear suspension systems often feel overly stiff or degrade after prolonged use. Harsh bumps transferring through the chassis and bottoming-out thumps when riding two-up with heavy luggage can compromise the refined riding experience expected from high-end vehicles.
To resolve these handling limitations, Monkey89 introduces the KYB K-Alpha Series Piggyback Rear Twin Shocks (365mm+10mm) for Honda SH150/160 VN / PCX 160 / Datbike Quantum S1 - Matte Black. Positioned in the 2W Performance high-grade aftermarket segment, this dual-shock setup features a stealthy Matte Black finish and piggyback gas reservoirs, delivering enhanced impact absorption and plush chassis stability on every journey.
TECHNICAL SPECIFICATIONS & ADJUSTABILITY
REAL-WORLD RIDER BENEFITS
-
Threaded Spring Preload Tuning: The fine-threaded adjustment collar allows precise preload setting to match total rider, passenger, and cargo weight. Whether commuting solo in urban traffic or two-up with heavy luggage, high-tensile steel springs absorb severe impacts, minimizing harsh bottom-out clunks and stroke compression limits.
-
Monotube Architecture with Nitrogen Piggyback Reservoir: The external reservoir keeps high-pressure nitrogen gas completely separated from the Japanese hydraulic fluid. Under continuous compression cycles over uneven roads, system pressure remains consistent, reducing chassis harshness and providing a plush, controlled ride.
-
Flexible Length Adjuster Collar (+10mm Extension): Allows height fine-tuning from 365mm up to 375mm (+10mm). Monkey89 engineering recommends an extension range of +5mm to +8mm to slightly increase ground clearance while maintaining safe damper rod travel.
-
Japanese Quality & Durability: Featuring a heavy-duty 15mm Hard Chrome plated shaft and double seal blocks to prevent contamination and fluid leakage, ensuring long-lasting smooth operation under demanding climate conditions.
FITMENT & COMPATIBILITY
Monkey89 ensures clear fitment specifications so you can choose with confidence:
-
Honda PCX 160 & Datbike Quantum S1: The standard 365mm geometry with top 10mm eyelet and bottom 8mm clevis mounts offers direct bolt-on (Plug-and-Play) installation. Ample bodywork clearance allows piggyback reservoirs to sit neatly, requiring zero fairing modifications.
-
Honda SH125/150/160 VN (2020-Present Models): Top 10mm eyelet and bottom 8mm clevis brackets align precisely with SH VN frame mounts and crankcase points. Due to the upward piggyback reservoir design, minor trimming of the inner rear mudguard plastic is required to provide proper operational clearance.
-
Installation Position: Symmetrical rear twin shock layout. Distributed by Monkey89 as genuine Japanese aftermarket stock in original box packaging.
