. In response, Laverda designed a scooter and the 200 twin. Francesco Laverda had an admiration with Triumph motorcycles. This was reflected in the twin cylinder design, single downtube front part of the frame and rear bodywork reminiscent of Triumph's 'bathtub' 3TA and 5TA models. Most European motorcycles has the gearchange on the right, but with a view to the American market the gearchange was placed in the left on the Bicilindrico. Intended as 'everyday' transport, the twin was first shown at the 1961 Milan Motorcycle Show and production started in 1962. The machine was available finished in light green, sky blue or orange. A prototype of a sports version was produced in 1964 but this was never put into production. It was fitted with an all tubular
