What is T.W.M.V. ? It means "Twin Wheeled Motorized Vehicles". I started using two-wheeled vehicles as transportation in 1984, going to school daily with a racing bycicle. In 1988 I started my life with the motorized vehicles buying a Monareta, manufactured by Monark, with a Termo 49cc engine. The photo below, taken by Sérgio Coutinho de Biasi in november 1988, at Colégio Santo Inácio, shows this first step.
After 11 years, I decided to buy another motorcycle, this time a Harley-Davidson. The engine is a 64 Pan-Shovel, 1200cc, older than me!
