The Dreer Prototype uses a Dave Taylor heim link at the top, and Windy's heim link at the front.
I'm still scratching my brain trying to come up with a simple, bolt-on rear/lower link to complete the triangulation.
As far as handling, my bike handles COMPLETELY different from any "traditional" Commando due to the monoshock rear suspension and Inverted forks. Geometry is different, and handling physics are different.
Bottom line: it's FAR superior to my MkIII by a HUGE margin. Identical engine, basic frame & adjustable isolastics.
...we won't even talk about the brakes...
