On the Honda NC 750 XA/XS (RH09), the seat height has been reduced from 830mm to 800mm compared to its predecessor.
Originally, the fork has progressive springs, whereby the first spring rate is too low and thus also changes early to the second spring rate, which is clearly too hard.
We use slightly harder springs here at first, but softer, progressive springs in the second spring rate. This conversion results in better fork response.
The rear shock is also fitted with a progressive spring from the factory, which has a poor block value and thus permanently stresses the second spring, which is again too hard.
Our solution relies on linear springs on the strut, in conjunction with optimized rebound and compression damping.
The suspension geometry on the front and rear axles was sensibly adjusted via the negative spring deflections in order to correct the negative spring weights, which were slightly too high as standard.
This results in a safer ride and better handling.
With this shock absorber the compression tank is connected to the shocks´ body by a flexible steel hose. Therefore it is an ideal alternative for road motorcycles with limited space. The hose can be placed individually where there is enough space for example on the rear frame where air flow can provide additional cooling. The adjustment screws for high- and low-speed compression, each tunable in 22 clicks, can be easily reached from the outside. Rebound can be modified by an open bleed system in 22 clicks and the preload is continuously adjustable.
