The TracTive X-TREME + EPA Rear shock for the BMW R1250GS (2018–2024) is a closed, pressurised, 46 mm rear shock built around a sealed cartridge design. This architecture keeps the damping oil under pressure to reduce cavitation and maintain consistent damping behaviour across varying conditions. This version is supplied in a Sport Chassis configuration with a 25 mm height increase.

Design & features

  • Closed, pressurised shock design for consistent damping and improved resistance to aeration.
  • Sealed cartridge construction to help maintain performance over time and under sustained load.
  • Remote reservoir with a fixed mounting style.
  • Supplied with an external preload adjuster (EPA) for convenient spring preload changes.

Tuning Controls

  • Triple adjustability: rebound damping and both low- and high-speed compression damping.
  • External preload adjustment via the included EPA.

Who is this for?

  • R1250GS riders who want broad, independent damping adjustment to tune for load, tyre choice, surfaces, and riding style.
  • Riders who regularly change between solo and luggage/passenger use and want faster preload changes via an external adjuster.
  • Those seeking a taller Sport Chassis set-up with a 25 mm ride-height increase.

Before You Install

  • Confirm the 25 mm Sport Chassis height change suits your intended seat height and handling goals.
  • Check clearance and routing for the remote reservoir and the external preload adjuster location.
  • After installation, set sag and then fine-tune damping in small steps, changing one control at a time.

Serviceability/Lifecycle

  • The sealed, pressurised construction is designed for consistent damping, and like any performance shock it should be serviced periodically to keep oil and seals in good condition.
  • If your use includes frequent long-distance or harsh conditions, plan preventative servicing to maintain performance.
