Bitubo 0.85 avec huile de fourche MOTOREX Fork springsRef : BITU00331A / 3031481

BITUBO Fork Spring Kit k=0.85 + Motorex Oil — a package designed to restore responsiveness and a clearer behavior to the fork of your Triumph 865. The kit includes two BITUBO springs with a stiffness of k=0.85, made from a specific steel alloy with heat treatment and shot peening for better durability, as well as one liter of Motorex fork oil to restore viscosity and seal the front end.

This kit is primarily aimed at roadsters and Triumph models equipped with the 865 cc engine (examples: Bonneville, Speedmaster, America). It allows for adjustment of the fork's spring rate for better braking control, improved sensitivity over small imperfections, and a more controlled stance when riding two-up or loaded, without altering the original geometry.

Kit contents:

• 2 BITUBO springs k=0.85
• 1 liter of MOTOREX fork oil

Installation recommended by a motorcycle professional: balancing, checking oil level, and adjusting preload/stroke to fully benefit from the kit. A simple mechanical upgrade piece to install for those seeking a more consistent fork that adapts to load variations.
