The TracTive rear shock for the BMW R 12 G/S is a closed, pressurised monotube design with a fixed reservoir. This architecture helps keep damping more consistent by separating gas and oil, especially when conditions get demanding. It’s built as a complete replacement rear shock assembly.

Design & features

Closed, pressurised monotube shock construction
Fixed reservoir with internal separation piston to keep gas and oil separated
Supplied with a spring as part of the shock assembly

Tuning Controls

Triple-adjustable damping: rebound plus compression adjustment with separate high- and low-speed circuits
Hydraulic preload adjuster for tool-free spring preload changes

Who is this for?

Riders who want broad, independent damping control for dialling in ride feel
Owners who regularly vary load (luggage/passenger) and want quick preload changes
Those looking for a pressurised, oil/gas-separated shock layout for more stable damping behaviour

Base Setup (factory preset)

This shock is supplied with a factory baseline tune intended to be a sensible starting point. Final settings will depend on rider weight, load, tyres and intended use.

Before You Install

Confirm the exact BMW model and year/application match for your R 12 G/S before ordering
Check clearance around the fixed reservoir location and routing space around the shock body
Ensure spring rate suitability for your typical load and riding conditions

Serviceability/Lifecycle

As a closed, pressurised shock, it is designed to be serviced to maintain performance over time. Service intervals depend on usage conditions and kilometres.
