| *This is a special edition shock that will be built in limited runs. |
The Arma MX is a direct bolt-on replacement for the Sur Ron Light Bee X and Talaria Sting. No additional Hardware is needed, simply bolt-on and go. Shock will be pre tuned by EXT-USA on the information you provide.
Engineered with performance and control as primary objectives, the shock structure has seen a redesign in order to be more robust. The Hydraulic Bottom-Out Circuit (HBC) has been enhanced with a wider range of adjustment, in order to prevent bottom-out issues, while allowing riders to use softer spring rates and providing excellent support and end stoke characteristics.
Together with the popular FERRO MX FORK, already known for its industry leading
reliability and performance, you can now have access to the best upgrade suspensions package on the market, purposely built to boost the performance of your electric dirt-bike.
