Progressive fork springs are originally installed in the Honda NT 1100 / SC84, where the first spring rate is too low, but the second is clearly too hard. In addition, the second spring rate is reached quite quickly due to a non-optimal block value. The damping in the fork is also not optimal in the series. The fork literally jumps towards you.
The Wilbers solution uses slightly harder springs at the beginning, but softer, progressive springs in the second spring rate. The block value is also optimised compared to the standard.
The Wilbers conversion results in a significantly better response of the fork.
On the shock absorber of the Honda NT1100 / SC84 there is also a progressive spring, which has a very bad block value, so that the rider is permanently riding in the second spring rate, which is also too hard.
In addition, the vehicle is equipped with a progressive lever system. In this combination, there is absolutely no comfort here in the series.
The Wilbers conversion relies on linear springs on the shock absorber, in combination with optimised rebound and compression damping. This results in maximum comfort.
The suspension geometry on the front and rear axle was sensibly adjusted via the negative spring deflections. Originally, the vehicle had too much negative spring travel.
For this reason, we also build the suspension strut slightly shorter than the standard. The seat height, however, remains the same as with the original chassis due to the adjustment of the negative spring travel. This is good for better handling and a safer ride.
The nonplus ultra concerning motorcycle shock absorbers! The upper mount consists of a milled part. It serves as a connection to the compression tank and houses the setup screws for the high- and low-speed areas of compression adjustment. With 22 clicks each they can be optimally tuned to your requirements! At maximum compression speed a pressure relief valve prevents the shock from hydraulic blocking and fends off uncontrolled jolts to the suspension. Rebound can be adjusted from the outside by 22 clicks. The spring basis is steplessly variable.
