Designed specifically for the Surron Ultra Bee, the EXT REA MX Shock is a direct bolt-on and features custom pre-tuning to match any riding style.
Featuring multiple spring rates, the EXT REA MX shock is custom-tailored to the rider’s weight and ability.
When testing, we found that the EXT REA MX Shock paired with the ECR Tuned KKE Fork is the best suspension pairing on the market.
EXT REA’s adjustable HBC design allows for progressive damping at the last 15% of the stroke, helping with stability under the most aggressive of riding.
In addition, the high-flow piston and low-friction coating and seal provide superior mid-stroke support.
Say goodbye to that wiggly fork that feels like it’s locking up, as this custom-tuned shock comes with an engineered rebound circuit that separates bump and rebound oil flow inside the piston.
