643 QSD — Diagonal, traversable reservoir.
Originally developed for the Honda VFR 1200, this Competition shock adds a diagonally mounted, rotatable compression reservoir to the Wilbers “construction kit,” unlocking multiple mounting options on bikes with limited space. The upper mount integrates the high- and low-speed compression adjusters for precise damping control. Spring preload is continuously adjustable with the supplied spanner or, optionally, hydraulically. Trained Wilbers partners can re-index the reservoir angle later if needed.
