EXT Arma MX Shock

Please fill in the EXT Order Form with every purchase. 

This shock is a direct bolt on replacement for the Sur Ron Light Bee X and Talaria Sting. No additional Hardware is needed. 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.

“Arma MX” is built around EXT's well established Arma MTB damper from which it inherited its name and all the properties that made its elder mountain bike dedicated brother famous.

However with Arma MX we put a lot of effort in developing a dedicate unique platform that offers some new implementations in terms of mechanical strength, to assure safe riding and unparalleled performance on those off-road electric vehicles, especially on the Sur-Ron e-bikes.

Main features:

• New head design: Arma Mx boasts a newly designed head obtained from a machined solid 7075 T6 aluminum piece, to increase resistance and reliability given the higher weight of the e-bike and its off-road and MX track usage
• Longer reservoir body: Longer reservoir body to accomodate longer damper stroke while keeping reservoir pressure at lower value, enhancing damper low friction quality and sensitivity even with higher temperatures.
• Steel chromed shaft: The steel chromed shaft grants an increased resistance and extra toughness with the addition of a proprietary special low friction coating to further reduce friction.
• Dedicated eyelet design and spherical bearings: Dedicated eyelet design to improve toughness and reliability and with spherical bearings to decrease friction and increase small bump sensitivity, traction and comfort.
• New cover guiding and strong negative spring: The cover guiding has been redesigned and inside of it a strong negative spring will improve platform stability, further protecting from harsh top-out and helping with the rearwheel/swingarm load.
• New high flow piston: New high flow piston design to improve sensitivity and tunability.
• New compression valve: The new compression valve will incerase the adjustability range and help providing a smoother consistent riding.
• New externally adjustable HBC: New externally adjustable HBC and more efficient design to increase bottom out protection.
