Triumph Sprint ST
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 favourite with riders who expect adaptability as a standard feature.
The hugely capable twin spar aluminium 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 favourite with serious riders. Only the graphics are changed to enhance the flowing lines and deep-finish colour scheme of the new machine.
And theThe 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 995cc 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 arevised to minimise 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 idle varying engine speeds to optimise 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 and starter motor drive areis now located on the left-hand end of the crankshaft and the starter motor drive is located on the right. This layout, featuring a compact rare earth magnet 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 minimise emissions.
Cooling and lubrication systems are revised with oil-jets to cool the undersides of the pistons. An increased 95 percent of the oil now passes through the new extra-capacity oil-cooler, while with the coolant radiator now employs featuringes 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.
