Fast Changing Technology for Motorcycles

By Paul Crowe

Think back just a few years. How many three wheel production motorcycles or cars were being produced? Not trike conversions using a “normal” motorcycle as a base vehicle but a three wheeler from day one. Were there any?

Leonhardt 410 Cubic Inch V-Twin Motorcycle

By Paul Crowe

Over a year ago I pointed out a project over in Germany being built by Clemens F. Leonhardt. Clemens had some very big ideas but at the time all you could see were design drawings, and when you consider what this project is supposed to be, it's easy to dismiss it as a design that will never happen.
