Shock Absorber Type 631 Competition

The Honda CB 750 Hornet comes with linear fork springs, which are a little too firm for their intended use. The Wilbers conversion therefore relies on progressive fork springs, which results in significantly better response and offers more reserve in the second spring rate than the standard equipment.

On the rear shock, a relatively hard spring is fitted ex-works, which for most riders hardly compresses at all in potholes and bumps. The solution from Wilbers relies on a somewhat softer spring with additionally adjusted rebound and compression damping.
This makes the Honda Hornet much more stable and comfortable to ride.

The negative spring deflections are a bit too low at delivery, both front and rear. This is corrected at Wilbers. Due to a slightly longer design of the Wilbers shock absorber, the seat height for the driver remains at standard height.

With compression tank on a flexible steel hose Wilbers Adjustline shock absorber type 631 is best suited for motorcycles with limited space! The compression reservoir is connected to the shock absorber by a flexible steel hose – hose length and mounting angles can be picked individually so that the reservoir always finds its optimal position, for example on the rear frame where the slip stream offers extra cooling. The compression tank houses the screws for tuning high- and low-speed compression damping in 22 clicks. At maximum compression speed a pressure control valve prevents the shock absorber from hydraulic blocking. The adjustment options in rebound, compression and spring preload offer you maximum control over your suspension!
