Wilbers fork springs for KTM 890 SMT, 2023-2025, for 30mm lowering

Product details

Wilbers fork spring set, progressive for 30mm lowering including reducing sleeves, for KTM 890 SMT, Type: D, Model Year 2023-2025 with ABE in preparation according to application area (fork oil to be ordered separately)

General description

Depending on the application, Wilbers offers progressive or linear fork springs, manufactured from the best and highest quality chrome-silicon steel. For touring and sport touring, we generally recommend a progressive fork spring to optimise responsiveness and increase bottoming resistance. Crucially, combine "Zero Friction" fork springs with the specially developed Wilbers fork oil and ensure the correct air chamber for the respective vehicle. If desired, individual tuning can be achieved in special cases by changing the air chamber. For motorsport applications, we recommend the very lightweight linear chrome-silicon fork springs from Wilbers, which were co-developed with the motorsport team.

"ZERO friction" friction reduction through vibratory finishing:
During vibratory finishing, the components to be processed, such as Wilbers fork springs, are placed together with an abrasive media specially adapted for this purpose in a vibrating container, known as a trough vibrator. The vibrations of the container create a relative movement between the workpiece and the abrasive media, leading to a smoothing of the componentupper surface through constant rubbing. At the end of the process, a fine, shiny surface is achieved. For Wilbers fork springs, this reduction in surface roughness means a minimisation of friction = ZERO friction.

Each set of fork springs includes a recommendation for the viscosity of the fork oil and the air chamber height in the fork. These values have been determined by experienced Wilbers technicians and ensure optimum riding comfort and feedback on the front wheel.

Note: please order the fork oil separately.
