This entry is the 1981 Tiger Trail, a dual-purpose derivative of the 750 Tiger with a 21-inch front wheel and Marzocchi rear units. A period road test judged it a hastily adapted road bike: strong engine, but heavy off-road and poor on tarmac with the knobbly tyres, with weak lighting and oil consumption.
