249cc Triumph Tigress
Sleek overhead valve twin-cylinder scooter providing comfort and economy with a high standard of mechanical and exhaust quietness.
Outstanding cleanliness of line is but one striking feature of the Triumph Tigress TW2, most recent creation from the versatile Edward Turner’s drawing board. Beneath the Tigress’ sleek bodywork (finished in metalescent blue) is a lusty 249cc overhead valve, twin-cylinder designed more on car than on orthodox motorcycle or scooter lines. Among the more unusual features of the power unit is an oversquare bore and stroke ratio (56 x 50.62mm). A single light alloy die casting is utilised for the cylinder block, crankcase and gearbox shell and the cylinder liners are cast in. Lubrication is on the wet sump principle with the oil contained in a deep steel pan of 2.5 pints
