EXT Arma E-MX Rear Shock Damper was designed for Sur-Ron, Segway, and Talaria electric bikes. The Arma E-MX by EXT is an easy-to-install, bolt-in rear shock suspension upgrade for enhanced performance. At Darwin EV, we include a 2-year warranty on all components.

EXT Arma E-MX Rear Shock Damper Compatibility:

  • Sur-Ron Light Bee X / Ultra Bee
  • Segway X160 / X260
  • Talaria Sting R MX4 / MX3

EXT Arma E-MX Rear Suspension Features:

  • Fully-Customizable Hydraulic Setup: specific for each rider / bike
  • Lightweight Spring Options: 400/450/500/550/600 lbs (lower weight available upon request)
  • Full Length and Travel: 10.5″ x 3.5″ shock – don’t use with 1.5″ riser linkage
  • 4-way Adjustable Hydraulic Bottom-Out Control: LSC-HSC-LSR-HBC
  • Easy Installation: direct, bolt-in, no additional hardware needed
  • Dedicated Eyelet Design: spherical bearing on both ends
  • Main Piston: high-flow 29mm / Valve Piston: 24mm
  • Shaft: 14mm – 50% larger than most coils for handling large side-loading events
  • Rebound Circuit: engineered to separate bump and rebound oil flow (ultra-low friction coating)
  • Very Low Reservoir Pressure: maximum sensitivity and low cavitation (55 PSI)
  • Very Low Hysteresis:  high dynamic response
  • High Turbulent Flow for progressive dampening + mid stroke support
  • Low-Friction Seal
  • Thin Bottom-Out Bumper
  • Washer for clearing debris
  • Low-Profile Rebound Knob for easy spring swap

The Hydraulic Bottom-Out Circuit (HBC) is engineered for performance and control, featuring a wide range of adjustment capabilities. This prevents bottom-out issues while allowing riders to use softer spring rates. It also provides enhanced support plus end-stoke characteristics.

EXT Arma E-MX Rear Shock Damper Includes:

  • rear shock damper
  • spring coil
  • mounting hardware (Sur-Ron)
  • no additional hardware needed

Limited-Edition: EXT Arma MX is built in limited runs
