Authentic Öhlins STX 36 Scooter Piggyback Twin Shocks For Honda SH150i Italy (Part #HO 813)
The Öhlins HO 813 rear twin shocks, part of the premium Öhlins STX 36 Scooter product line, set a new standard for quality, performance, and durability specifically for the Italian-made Honda SH150i (2012-2018). Featuring a high-pressure, nitrogen gas-charged monotube design equipped with an external piggyback reservoir, this setup ensures optimal temperature control. Notably, these shocks are fully equipped with all three premium adjustment features: Compression, Rebound, and Spring Preload. Crafted from hard-anodized precision CNC-machined aluminum, combined with a low-friction steel shaft and high-tensile springs, these shocks elevate the look of your scooter while providing a smoother, more controlled, and highly enjoyable ride.
The Italian SH150i is famous for its luxurious design, but the factory rear suspension is often considered harsh in congested city traffic. The Öhlins STX 36 Scooter (HO 813) completely transforms the riding dynamics through:
1. Optimal Reservoir-on-Top Design The integrated piggyback reservoir dissipates heat rapidly, maintaining stable oil pressure even when operating continuously in hot urban traffic conditions. This ensures consistent damping force without fading or high-speed float.
2. High-Pressure Nitrogen Gas & Premium Materials The 36mm nitrogen gas-charged Monotube system eliminates oscillations extremely quickly, providing clear road feedback while retaining plushness thanks to the low-friction shaft design. The hard-anodized CNC aluminum construction provides maximum corrosion resistance and durability.
3. Comprehensive Rebound, Compression, and Preload Tuning The system offers flexible tuning across all three adjustment parameters, allowing the rider to personalize the damping to their physical needs. The kit also includes a high-quality billet preload adjustment tool, making spring compression changes effortless and precise.
REAL-WORLD URBAN PERFORMANCE
-
Absolute Plushness Over Speed Bumps: In real-world conditions, the Öhlins shocks handle potholes and speed bumps seamlessly, neutralizing harsh impacts transmitted to the spine. The ride quality becomes noticeably more luxurious, protecting the rider's health and increasing passenger comfort.
-
Solid Stability with Heavy Loads: Thanks to the 75 mm stroke, the scooter no longer sags under heavy loads. The suspension works harmoniously to maintain proper steering geometry, delivering a naturally balanced riding experience far superior to the stock setup.
-
Expert Insight (Information Gain): A highly valuable feature of the HO 813 kit is the included alternative springs. According to the manufacturer, the pre-installed springs (Part #60001-08) feature a progressive rate of 16-21 N/mm, optimized for riders weighing below 90 kg. However, the kit provides alternative springs (Part #60004-05) with a stiffer 19-27 N/mm rate specifically for total loads exceeding 90 kg. This guarantees the shock operates within its optimal stroke range, preventing bottoming out and potential damage to the hydraulic shaft.
