Abstract

A 3 wheeled motorcycle in which the vertical axis of all 3 wheels remains parallel, capable of counter-steer/lean when making a turn.

Claims

1. An arrangement in which the vertical axis of three wheels remains parallel permitting counter-steer and lean.

2. A drive arrangement which incorporates a differential assembly to allow difference in drive wheel speeds in a turn.

3. A suspension arrangement in which vertical movement of wheel is independent of other wheels.

4. A suspension arrangement in which rear body angle remains parallel with roadway surface, independent of wheel and front body angle/lean.

5. A suspension arrangement in which shock absorbers and brake calipers are incorporated.

6. A suspension arrangement in which unit will be self centering upon relaxation of steering input effort.
