Triumph Speed Triple

From Triumph Press Release

From its new chassis and bodywork to the modified new generation Daytona engine, the 2002 Speed Triple takes the concept of the factory streetfighter to new levels. The Speed Triple now offers more performance than any similar machine with arresting styling unlike any other production bike. There’s more power – up by 10bhp to a punchy 120bhp - aggressive new curves from revised bodywork while the handling is as agile and responsive as ever. Derived from the new 955cc Daytona 955i motor, the Speed Triple’s powerplant now runs cooler and produces comfortably more power than its predecessor.Both inlet and exhaust ports are redesigned for better gas flow and the new cast pistons run in steel liners. A larger, reshaped airbox feeds the new closed-loop fuel injection system, which features smaller, lighter injectors.

The closed-loop system features an oxygen sensor that monitors and adjusts the air/fuel ratio at varying engine speeds to optimise engine performance, while compact, light plug-top ignition coils provide high intensity sparks. The injection mapping is tuned for effortless mid-range torque. As with the new Daytona 955i 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 it eliminates the need for a gear train to drive the alternator. A revised claw-type gear-change mechanism gives a much smoother and more positive shift action. The new chassis is also lighter, more agile and quicker-steering. Wheelbase is reduced by 11mm to 1429mm, steering geometry is steepened for increased agility with rake and trail figures of 23.5 degrees and 84mm (previously 24 degrees and 86mm). The rear of the bike is raised to increase ground clearance, which at the same time accentuates the aggressive stance of the new machine.

A new lightweight 17-inch front wheel (same as on the TT600) saves 450g of unsprung weight and further improves steering response. The tubular aluminium frame has been revised and a new rear subframe has been fitted. Showa 45mm diameter forks with dual-rate springs and multi-adjustable damping take care of the front suspension, whilst at the rear the single-sided swingarm and multi adjustable rear shock is retained. Faster, slimmer, more agile and with its kicked-up tail and new bodywork, the Speed Triple looks even more individualistic and aggressive than ever.

Key changes:

  • Second-generation fuel-injected engine delivering 120bhp and masses of midrange torque.
  • Revised chassis with shorter wheelbase, sharper steering geometry and raised rear ride height.
  • Restyled bodywork, digital instruments and more compact twin-headlight arrangement.
  • 7kg lighter at 189kg.
