– 2004 Triumph Speedmaster
Just as the America re-defined a lot of perceptions about cruising motorcycles, so the Speedmaster defines a fast-developing niche that exists for more performance-orientated cruisers.
The Speedmaster is built around the America’s proven low-slung chassis and 790cc twin-cylinder engine but has the tougher, pared-down look of a bare-knuckle hot rod. The DOHC eight-valve air-cooled engine uses the same 270° crankshaft firing interval as the America but vents through a pair of long, deep-chromed silencers. The satin-black engine finish adds a crisp edge to the Speedmaster’s handsome lines as does the slightly more aggressive riding position. High risers mount the flat ‘drag’ handlebars on the slab-style top yoke and match the chromed, forward-set footpegs.
Minimalism is key to the Speedmaster’s ethos. The rev-counter is mounted discretely on the fuel-tank nacelle while the large round white-faced speedo perches above the top-yoke. The tank itself holds 16.6 litres of fuel (4.4 gal US), giving a useful range. The Speedmaster’s paint options of Jet Black with Tornado Red or Racing Yellow infills are joined in 2004 with an infill of Sky Blue. Alternatively, for those who prefer simplicity, a plain Jet Black option is available.
Twin front discs – gripped by twin-piston calipers – haul the Speedmaster up hard. Cast wheels add style – the 18-inch front wears a 110/80 tyre, the nearly solid 15-inch rear a 170/80 – and the twin shocks and wide-style telescopic forks straighten the curves and iron out the bumps, giving a controlled and supple ride.
And if the Speedmaster’s bare bones want a little more flesh on them… the Triumph accessory range features an array of bolt-ons specifically designed to give the Speedmaster even more edge.
