Thruxton is a well-known racing circuit
in Hampshire and following the 1969 success of a first,
second and third-placed romp home for Triumph in the Thruxton
500 (a 500-mile endurance race), a series of very special racing
Bonnevilles was born.
The
Bonneville Thruxtons back then were essentially racers
for the road with tuned engines and a pared-down style that inspired
the café racing street motorcyclists of the time. Over
thirty years later that essence of raw motorcycling and svelte
café-racer lines is still very much a magnetic draw. Now,
in 2004, a new breed of Triumph Thruxton is ready to inspire a
new generation of road riders.
To create the new Thruxton 900 the Bonneville’s 790cc air-cooled
twin-cylinder engine was enlarged to 865cc. Then tuned with new
cams, new carburettors and megaphone-style exhausts for more power
and torque, everywhere. The Thruxton’s engine has a peak
power output of 70PS (69bhp) at 7,250rpm. Peak torque of 72Nm
(53ft.lbf) is found at 5,750rpm. Polished engine covers add to
the Thruxton’s appeal, as do clip-on handlebars and rearward-set
footpegs.
Revised telescopic forks and longer rear shocks (both with preload
adjustment) enhance the suspension action and compliance while
sharper steering geometry aids responsive handling. A fully floating
front disc and twin-piston brake caliper provide powerful, yet
sensitive, braking performance. The tubular steel twin cradle
frame and box section swingarm are more than capable of making
use of the engine’s increased power output. Finishing off
the new Thruxton is a shorty front mudguard and evocatively shaped
seat hump, further reinforcing the bike’s café-racer
appeal.
Colour options available are Jet Black or Sunset Red, both with
a chequered-flag tank graphic and silver mudguards, and both complement
the bike’s clean lines. With a name that holds real magic
for Triumph, from a very different era, the new Thruxton is a
machine built for sheer riding pleasure. And it is as elementally
beautiful now as it was then.
