Wilbers Progressive Fork Springs - ZERO Friction
For BMW F900GS with standard suspension
Wilbers fork springs combine progressive spring characteristics with cutting-edge friction reduction technology - the result: ZERO friction. The friction reduction is achieved through precise glide polishing. The springs are processed together with specially matched polishing media in a vibrating container. The continuous relative movements smooth the surface of the springs, resulting in a fine, glossy finish. For the fork springs, this means significantly reduced surface roughness and therefore minimized friction. Full performance is achieved in combination with the Wilbers fork oil and the correctly adjusted air chamber.
For optimal results, we recommend:
Fork oil: SAE 7.5 (2 L)
Air chamber: 140 mm
