Brudeli Leanster 654L

This is a bike that was developed in Norway by Geir Brudeli. We were members of the same motorcycle club in 1987.

Yamaha has just bought his patents in leaning technology and he is working on a new project. The bikes are powered by a KTM engine.

I remember his first project in 1990 when he converted a VW Beetle engine into a V4 and built a motorcycle around it. Power was transfered to the rear wheel through a Volvo gearbox. The bike on idle sounded like 2 Harleys idling.

Yamaha did launch a similar bike a couple of years bike, Niken 700. Niken seems to be have a different mechanism in the front for the 2 wheels. Maybe they want to refine it using this design.

I have always wondered whether these type of bikes have an inherent self-centering property. That is do they tend to come back to the vertical position after a lean or is it up to the rider?

Being equally sprung on both front control arms should make it come back to center, but that itself will be sort of a deterrent when you would want to lean in. The springs should provide equal force at all length or the vehicle would feel very springy in and out of the lean. Also, in a lean, both sides would have difference in the spring force so it would be very difficult to predict its balance while leaning and on uneven or rough surfaces.

Its all very fascinating.
