Comments
The only diesel motorcycle to enter mass production, with a 325 cc 6.5 bhp Lombardini diesel engine, and 3.5 hp version, the gearbox was reinforced to withstand increased torque associated with a diesel engine. The Taurus came with heavy-duty luggage rack for vending jobs and economy up to 72 kmpl,but the top speed was limited to roughly 80 km/h by its lack of power.
