Stage 4 - Black by Touratech: a Closed Cartridge kit designed for the front end for demanding riders. Designed to fit into the original fork, this suspension module replaces the damping function without altering the steering stem, handlebar mount, brakes, or the geometry of the motorcycle. Particularly suitable for the Triumph Thruxton-R (2016-2018).
The principle: damping oil enclosed in a sealed cartridge and nitrogen separated in a bubble, with the remaining oil in the fork reserved for lubrication. This separation reduces foam formation and stick-slip, providing a more consistent response from the fork even under heavy loads. The integrated "Hydraulic Endstop" smoothly limits bottoming out.
Main features:
- Colour: Black
- Suspension height: Standard height
- Approval: ABE
- Mounting location: front
- Piston Ø 35 mm for robustness and stability
- Adjustments: preload from the top (20 mm over 12 clicks), rebound 20 clicks, pressure level 20 clicks (per rail)
Supplied with:

- Adjustment tool (preload) and installation instructions
- Mounting oil and 2 × fork protection stickers
Ideal for loaded rides, mixed journeys, or riders who want fine and reproducible adjustments of the front end. For personalised advice, the Touratech suspension service remains available.
