At EXT we are always focused on offering the best possible product for the specific application. Race cars, SSVs, motos, bikes, ATVs, every vehicle has its characteristics and requires custom solutions to achieve the best possible performance, safety and comfort.
This is why with the growing worldwide success of electric dirt bikes, and in particular of the ones produced by the Sur-Ron brand, we realized that there was the need to develop a bespoke damper that won’t only improve the performance of these particular vehicles but also increase safety, reliability and fun.
“Arma MX” is built around our well established Arma MTB damper from which it inherited its name and all the properties that made its older 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.
