The M-Shock rear shock absorber for Triumph Trident 660 (from 2021) 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. Adjustment is quick, accessible and requires no specific 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.
This product includes a factory setup service carried out by Shock Factory before dispatch. Based on the information provided at the time of order - solo or two-up use, rider weight with gear, luggage frequency and weight - the shock absorber is individually calibrated to be ready to use immediately after fitting, with no additional adjustment required.
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

Original shock absorbers are often designed for standard use and low cost. FCR Accessories shock absorbers (Shock Factory, for example) offer improved comfort, optimized handling, and increased stability, especially when riding two-up or on uneven roads. They literally transform the motorcycle's behavior, while also improving safety and handling precision.
Each Triumph shock absorber model is developed for a specific chassis and geometry: Bobber, Bonneville, Trident, Thruxton, Street Twin, etc. Compatibility information is always indicated in the product descriptions. If you are unsure, our team can confirm the correct model for your motorcycle before you order.
Yes, the majority of shock absorbers offered by FCR Accessories have rebound and spring preload adjustments. Some higher-end models also offer compression damping adjustment. These adjustments allow you to tailor the motorcycle's handling to your weight, riding style, and road conditions.
No, the assembly is generally plug & play, without modification to the original frame or suspension. Each kit comes ready to install, and the original Triumph fixing points are retained. If you prefer, the assembly can be carried out in our FCR Accessoires workshop by appointment.
Yes, most of the Shock Factory M-Shock shock absorbers we offer are entirely manufactured and assembled in France. Each unit is hand-assembled and calibrated according to the motorcycle model and rider profile, ensuring consistent performance and long service life.
A quality shock absorber, well maintained, can last more than 50,000 km. Regularly checking the condition of the seals, preload and screws helps to extend its lifespan. FCR Accessories parts prioritize repairable and serviceable components, for long-term, sustainable maintenance.
