The EXT REA-MX Shock Absorber is a revolutionary rear suspension system designed specifically for high-performance electric dirt bikes like the Sur-Ron Ultra Bee.
Drawing on decades of expertise in motocross suspension, EXT has crafted the REA-MX rear shock to deliver unparalleled performance, durability, and adjustability for demanding riders.
ENGINEERED FOR MAXIMUM PERFORMANCE
The EXT REA-MX rear shock is built around a 40mm piston and 16mm shaft, providing robust performance and stability under extreme conditions.
Featuring hydraulic bottom-out control (HBC), this suspension system offers progressive damping support, allowing riders to confidently push their limits while maintaining exceptional control.
Its high-flow piston design makes sure that you have smooth and consistent rebound oil flow, even under intense loads, while the very low reservoir pressure minimizes hysteresis, delivering a more responsive ride.
KEY FEATURES OF THE EXT REA-MX SHOCK ABSORBER
- High-Flow Piston Design: Improves oil flow for consistent damping across all terrains.
- 4-Way Adjustability: Customize your ride with compression adjustments for high and low speed, rebound settings, and HBC.
- Hydraulic Bottom-Out Control: Prevents harsh landings and maintains optimal stability during jumps and rough terrain.
- Ultra Low-Friction Coating: Reduces wear and tear for a smoother, longer-lasting performance.
- High-Load Spherical Bearings: Provides superior durability and precise alignment under heavy loads.
- Special Ultra Lightweight Springs: Reduces the overall weight of the system while maintaining high performance and maximum sensitivity.
- Very low hysteresis: No matter if you have softer or stiffer springs, the lag of the shock is low.
BUILT FOR THE SUR-RON ULTRA BEE
The EXT REA-MX shock is tailor-made for large electric motorcycles, making it the perfect shock for SurRon Ultra Bee riders.
Its softer main spring rate delivers better comfort for lighter riders while providing a balanced response for heavier loads. Designed to accommodate maximum weight limits, this suspension system is ideal for varied riding conditions, from technical trails to fast-paced motocross tracks.
INNOVATIVE TECHNOLOGY
EXT's dedication to innovation is evident in the REA-MX offroad shock, with features that set it apart from standard motocross suspension systems:
- Low Reservoir Pressure: Maintains consistent damping and reduces heat buildup, making sure that you get reliable performance during long rides.
- Large Reservoir: Provides ample capacity for oil and gas, improving cooling and extending shock longevity.
- Low-Friction Seals: Minimize resistance for smoother operation and reduced maintenance needs.
