14/02/2005: "Triumph Motorcycles Speed Four Motorcycle"
A sporty, middleweight motorcycle has to perform in many environments - from racetrack to city street and winding back road, perhaps in one day. And the Speed Four has been built not just to perform.
But to amaze.
Its lineage is pure supersports but with a twist - an X-factor - all of its own. The Speed Four's howling 599cc, four-cylinder, fuel-injected engine gives instant, thrilling power all the way to the redline and its taut, race-spec chassis and high quality, fully adjustable suspension connects the rider intuitively to the road flashing beneath.
The naked, bare-boned style of the Speed Four marks its individuality, unique character and eagerness to stand well clear of the workaday, homogenous masses. It's a statement of attitude mixed with a shot of pure adrenaline. And fittingly the Speed Four is not merely ridden; it's worn as an extension of the soul.
