2002 Triumph Bonneville
|
The air-cooled 790cc
engine in Triumph's Bonneville has a 360 degree firing angle crankshaft of
the Bonneville produce a modest 60Nm (44ft-lb) of torque - a substantial
90 per cent of it from 2750rpm all the way to the redline. And a peak
power output of 61bhp at 7400rpm. The triangular engine cover on the right and clutch case on the left, both in brushed and lacquered aluminium for 2002, are authentic touches at the core of the Bonneville look. The compact twin overhead camshafts keep the engine's top end visually similar to previous Bonneville engines, likewise the engine breather runs in what looks like the distinctive pushrod tube of years past. There's even a compact and discreet frame-mounted oil-cooler to keep the running consistent for maximum reliability. Twin 36mm carburetors with throttle-position sensors feed the donk and these are electrically heated to prevent carburetor icing. The exhaust features twin 'peashooter' silencers and secondary air-injection to keep emissions to a minimum. Twin balancer-shafts reduce vibration but allow the engine to feel like a traditional 360-degree twin. The chassis is based around a tubular steel double cradle frame and a box-section steel swing-arm offering light, easy steering around town and sure-footed handling at speed. With a low centre of gravity and low 775mm (30.5in) seat height, the Bonneville feels light and manoeuvrable. With disc brakes front and rear, and a 19in front and 17in rear wheel fitted with modern profile tyres, stopping and road-holding are way beyond what the traditional looks might suggest. And tradition is so much a part of this machine - from the classical tank badge and the deep, lustrous finish of the hand-pinstriped tanks (there is a new Sky Blue & Silver option for 2002) to the timeless lines and unmistakable sound, the Bonneville remains a true original.
