2005 Triumph Bonneville T100

Triumph Bonneville T100

Adding subtle touches to the uncluttered Bonneville form, the T100 roadster, with its tachometer, rubber knee grips and chromed engine covers wears a little extra to mark its connection with the classic speedster of the sixties. And it has a little extra spice now, too.

The extra bite comes from the full-blooded, 865cc, air-cooled, parallel twin-cylinder engine now powering the T100. Delivering throaty performance - echoed by the mellow backbeat from its twin pea-shooter exhaust pipes - a bore and stroke of 90 x 68mm, compression ratio of 9.2:1 and 360 firing interval add up to a responsive, punchy and soulful power unit.

The T100's chassis thrives on the extra power and torque available from the engine delivering secure road-holding, effortless steering and easy-going manners - as you'd expect of a motorcycle drawn from Bonneville stock. The tubular steel frame, 41mm telescopic forks and chromed twin rear shocks easily cope with the extra performance the engine imparts, as do the powerful twin-piston calipers operating on the front and rear discs.

Today the T100 is the very essence of style and individuality, just as it was 40 years ago. All of the T100's crisp coach lines are hand-applied - as they were back then - and new for 2005 is the supremely elegant two-tone Opal White with Tangerine infill paint scheme, which provides a striking alternative to the stunning Jet Black with White infill.

The Bonneville T100 remains a timeless machine - a pleasure to ride, to own. It's a machine with a unique character that defies comparison. It's an individual motorcycle and individual choice.
