The Britten is often described as having a girder front-end even though it's clearly a Hossack/Fior design.

The BMW Telelever is a Saxon-Motodd copy and operates quite differently from the Hossack. In the Saxon-Motodd design, suspension is still a function of the uprights (telescopic forks) but suspension loads are input into the chassis from both the A-arm and steering head. In the Hossack design the upright is merely a steered component and all suspension loads are carried by the two A-arms.

The Hossack system should be ideal for sidecar useage and if combined with a steerable sidecar wheel (about 50% of the front wheel input) and a torsion bar interconnect to the rear wheel (a concept well-proven by MZ-Stoye with the Superelastik) would create a delightful outfit.

Unfortunately the Australian ADR width limits tend to make a steerable sidecar wheel VERY difficult.
