Massimo Zancai is an engineer who has done custom work for concept motorcycles by the likes of Moto Guzzi and Aprilia, fabricating parts for bikes by the two companies in the last several years. La Motocicletta is his passion project — a chance to design and build bikes to his own tastes without the restrictions of client work. One of his latest builds is this 1983 BMW R80ST, a street version of the BMW R80, one of the bikes that helped launch the dual-sport motorcycle segment. The heart of any motorcycle build is the engine, which was torn down and rebuilt using internals from a larger R100 engine, adding a healthy dose of power and torque without changing the external appearance. New USD forks were added with dual radial calipers and wave discs at the front, and a new monoshock at the rear. The tank features the speedometer with hidden wiring and mounting brackets giving an ultra-clean look.
