TSS slipper clutch Triumph 1050/955i 1997-2020

TSS slipper clutch Triumph 1050/955i 1997-2020 is a technical solution for riders seeking greater stability during braking and downshifting. Reference 17003 is intended for Triumph 1050 / 955i A slipper clutch works when the torque coming from the rear wheel exceeds the torque delivered by the engine during deceleration. Its mechanism then allows controlled clutch-plate slip, reducing harsh reactions through the transmission.

More stable downshifts

During hard braking, the rider may shift down several gears in a short time. With a conventional clutch this can cause temporary rear-wheel lock-up, hopping or sideways movement. The TSS system reduces this effect and helps the motorcycle remain more neutral. The rider can focus on the braking point, line and corner-entry speed. This behaviour is especially useful on track and also provides greater control during sporty road riding.

Main TSS clutch benefits

• reduced rear-wheel hopping and judder;
• improved stability under braking and downshifting;
• smoother, more accurate corner entry;
• less stress on the transmission during sudden deceleration;
• application-specific construction for the listed motorcycle.

Contents and compatibility

The package contains only the components stated for reference 17003. Clutch plates, springs, basket or ancillary parts are included only when expressly listed in the title and supplier description. Before installation, compare the delivered components with the original clutch and check the motorcycle model, version and year carefully.

Installation advice

Installation must follow the motorcycle manufacturer’s specifications and the instructions supplied by TSS. Plate order, tightening torques, operating clearances and the recommended oil grade must be respected. Professional installation is advised, particularly for racing use. After fitting, check clutch-control operation, make sure there are no abnormal noises and verify correct engagement of every gear before riding. Regular inspection of plates and springs helps maintain consistent performance.

TSS clutch technology

TSS develops performance-oriented slipper-clutch systems. This reference provides more predictable behaviour during braking while retaining application-specific compatibility with Triumph 1050 / 955i.

Choosing the right TSS slipper clutch

Check the exact motorcycle model, version and production year before ordering, then compare the stated configuration with the components already fitted to the bike. For track use, also consider the condition of the original plates, springs, control system and oil. A coherent assembly gives more consistent lever feel and predictable deceleration. It also makes later maintenance easier because each wear component can be inspected against a known, application-specific setup.
