Triumph motorcycles are legendary for their performance — and reliability issues. This trick Bonneville T140 is a throwback to the great TT racers of the past, with a bevy of serious upgrades. A hand-made TT-style tank and rear fairing are the most noticeable pieces, but the real magic is in the suspension and motor. Ohlins forks and a custom monoshock rear suspension keep the bike on the ground. The centerpiece is the glorious parallel-twin, 750cc engine. Ported, polished, with strengthened internals, larger valves, and larger flat-slide carbs ensure that this elder statesman of British motorcycling goes as good as it looks.
