Triumph Speed 400 M-Shock Rear Shock

M-Shock rear shock absorber for Triumph Speed 400 - Synchronised adjustment for demanding road use

The M-Shock rear shock absorber for Triumph Speed 400 was developed to address the limitations of the standard suspension and deliver a tangible improvement in road behaviour. It is aimed at riders looking for a better balance between comfort, stability and riding precision, whether in daily use or more committed riding.

Its adjustment system is built around a single dial acting simultaneously on compression and rebound across 48 positions. This synchronisation of both hydraulic parameters ensures a consistent balance regardless of the chosen setting, without upsetting the overall behaviour of the motorcycle. Too soft or too firm: two clicks are enough to feel the difference, directly on the motorcycle, without any tooling.

The progressive hydraulics absorb road surface irregularities effectively while maintaining a firm response under heavier compression loads, notably during hard braking or aggressive cornering. The rear wheel maintains better contact with the road surface, directly improving traction, line-holding and overall feedback to the rider.

Every shock absorber is individually tested on a Roehrig dyno before dispatch, ensuring a compliant performance curve and consistent output over time. Fitting is a direct replacement for the standard unit, with no structural modification to the motorcycle required.

Spring colour:
Solo use, rider and equipment up to 120 kg: black or red spring
Solo use, rider and equipment over 120 kg / two-up riding: red spring required
