Manufacturers have always groped to find solutions, the most common temptation being to reduce the hydraulic curve, giving an impression of comfort on certain impacts.
BOS Suspension engineers took a rather different direction, focusing directly on the particularities of these strong percussions. You can’t contradict fluid mechanics, you have to adapt to it. We have therefore worked to be able to adjust and redefine specifically the threshold from which the wheel is allowed to go up during these strong impacts.
The solution is a unique frequency sensor: The weight of the FCV system is tuned to move only at high frequencies. The system only opens on strong percussion by increasing the flow through the valves.
Originally developed for mountain biking, this technology has proven itself in competition:
in 2013 the BOS rider Rém Thirion won a downhill mountain bike world cup round in Andorra with a fork equipped with FCV. It was at this time that the decision to apply this technology to MX motorcycles was taken.
In motocross, Livia Lancelot wins with the FCV-equipped air fork less than a month after its release.
In car rallying, the feedback from the drivers has been very good, with several victories at stake, such as in the Dakar stages with Carlos Sainz
