First unveiled at the end of 1998, Triumph's Sprint ST is the Hinckley firm's interpretation of the modern sports-tourer bike. Long dominated by Honda's VFR800, this competitive sector of the market requires a machine with the comfort for easy 1200km (750-mile) days, as well as track-friendly performance on arrival. On paper, the Sprint ST fits the bill. Powered by Triumph's latest 955cc three-cylinder engine, the ST can hit 256km/h (160mph), while weighing less than the VFR, at just 207kg (4561b). Adjustable suspension and sporty tyres add chassis sporting potential, and the sleek bodywork and single-sided swingarm supply classic good looks. Strong, sportsbike brakes give class-leading performance.

Already regarded as one of the most versatile motorcycles in the world the 2002 Sprint ST benefits from the same heavily-revised engine fitted to the latest Speed Triple and the Sprint RS.

A machine as happy scratching through back lanes as it is hitting the continent on long hauls, the Sprint ST remains a firm favorite with riders who expect adaptability as a standard feature.

The hugely capable twin spar aluminum chassis and single-sided swing-arm remain unchanged. Clever touches like the two-position exhaust, either fixed high for added cornering clearance, or lower down to allow room for fitted luggage remain a reason why this bike is a favorite with serious riders. Only the graphics are changed to enhance the flowing lines and deep-finish color scheme of the new machine.

The engine changes offer even more of the long-legged performance the Sprint ST is renowned for. The new 120bhp powerplant is identical to the new 955cc three-cylinder engine fitted to the new Speed Triple and Sprint RS. Employing high-pressure die-cast crankcases for both strength and lightness, the DOHC 12-valve liquid-cooled engine’s new cylinder head utilizes 1mm larger inlet valves and 1mm smaller exhaust valves, set at a narrower included angle. Both inlet and exhaust ports are redesigned for better gas flow and the new cast pistons run in steel liners. Compression ratio is up from 11.2:1 to 12:1.while crankcase breathing is revised to minimize power loss. The new engine is 2.5kg lighter than before.

A larger airbox feeds the new closed loop fuel injection system which features smaller, lighter injectors, while compact, light plug-top ignition coils provide dependable high-intensity sparks. The closed-loop system features an oxygen sensor that monitors and adjusts the air: fuel ratio at varying engine speeds to optimize engine performance. The fuel injection mapping is tuned for even more mid-range torque making the Sprint ST’s punchy three-cylinder performance even easier to use to the full.

As on the Speed Triple engine, the alternator is now located on the left-hand end of the crankshaft and the starter motor drive is located on the right. This layout, reduces noise, especially at idle, as there’s now no need for a gear-train to drive the alternator. And a revised claw-type gear-change mechanism gives a much smoother and more positive shift action.

The exhaust system has new headers and balance-pipe to further boost midrange output and for the German and Californian markets a secondary air injection system is fitted to minimize emissions.

Cooling and lubrication systems are revised with the coolant radiator featuring a thinner core, increasing efficiency without adding size or weight.

The Sprint ST is available in distinctive British Racing Green, cool Sapphire Blue and dashing Tornado Red.
