The Sirris R38 shock brings full-size suspension technology to the Surron Light Bee X. Built with internal architecture shared with the larger R46 platform, a 16mm shaft, and a compact 38mm piston, it delivers consistent damping, precise adjustment, and the durability needed for aggressive riding.
CMX (Compact Motocross) tuning and high-flow internals provide responsive damping and support through repeated hard hits. The 2SC (Two Stage Compression) system offers independent high-speed and low-speed compression adjustment, along with tool-free low-speed compression and rebound adjusters.
Designed specifically for the Light Bee X and developed to pair with the Sirris F43 CMX fork.
Note: The R38 requires the Sirris/Prickly R38 LBX-specific linkage and triangle, sold separately. [The stock LBX linkage and triangle will not work with this shock.]

Key Features
-
CMX Tune: Compact Motocross damping with fully tunable compression and rebound circuits, developed specifically for the Light Bee X.
-
Independent compression adjustment: The 2SC system provides separate high-speed and low-speed compression adjustments for greater control over suspension feel.
-
R46-based internals: Shares the larger R46’s high-flow base valve cavity architecture for responsive, consistent damping.
-
Full-size shaft: A 16mm induction-hardened, chrome-plated hollow steel shaft provides structural strength and high oil flow through the main piston.
-
Compact construction: A smaller shock body, spring, retainers, and hardware package accommodate compact bike platforms while preserving high-flow internal performance.
-
Large floating piston reservoir: An R46-spec internal floating piston system manages shaft displacement and helps maintain consistent damping through repeated hard hits and high heat loads.
-
Durable construction: Type 3 hard anodized aluminum components and chrome-plated, Teflon-lined
