More Hossack for many

The Japanese motorcycle giant Honda seems to be considering saying goodbye to the conventional telescopic fork. A new patent specification shows another infusion of the Hossack fork principle.

The widely used telescopic fork has reached a high level of evolution and a high degree of maturity. The system-related disadvantage of brake diving has remained to this day. As you descend when braking, the steering geometry and the damping behavior also change.

With alternative constructions such as the Telelever or the Duolever (both from BMW) as well as other developments based on the Hossack fork, these disadvantages could be eliminated. The constructions rely on an unsprung wheel fork that is connected to the frame by means of triangular links. A centrally integrated suspension strut takes over the spring and damping work. The steering movements are transmitted via a scissor-like joint. Depending on the selected geometry, diving can be reduced or completely prevented.

The flexural rigidity of such a construction is also superior to that of a conventional telescopic fork. By separating wheel guidance and suspension, the latter can also be designed to be much more sensitive – in other words, suspension comfort increases. Due to the generally higher masses, however, the moment of inertia around the steering axis increases. Such front wheel guides also require more installation space. In addition, the driver is off the front wheel “felt” more decoupled. Many pilots complain about insufficient feedback.

Gold Wing front suspension for the base too

Honda is currently using the Hossack principle for front suspension in the Gold Wing. However, a patent published in the USA shows a correspondingly designed front wheel suspension for a Honda Cub – the most built two-wheeler in the world. A patent published almost at the same time in Japan deals with the Hossack fork on a Honda CB 1100. Corresponding patent applications for a similar fork system on an RC213V were already made in 2016.

As with other patents, this also applies here. Just because manufacturers have such systems protected does not mean that they will go into series production. It is only noteworthy that Honda is thinking about a similar front wheel suspension in a spread from the high-tech supertourer Gold Wing to the Cub, the mass model for Asia par excellence. Maybe the days of Telegabel dominance are numbered.
