Generations

955 cc

The Sprint ST was first introduced in 1999 as a complete redesign of the earlier Sprint 900 (1993–1998) styled by Rod Scivyer. It made use of a 955 cc straight-three engine similar to those found in the contemporaneous Speed Triple and Daytona models, only slightly retuned for smoother power delivery. Power was claimed to be 105 bhp (78 kW).

The model's appearance remained mostly unchanged from its introduction in 1999. An engine revamp with the assistance of Lotus in 2002 increased output to 118 bhp (88 kW) at 9100rpm and 100 N·m (74 lbf·ft) of torque at 5100rpm from a lighter enginethe bike is 207 kg (456 lb) dry.

1,050 cc

In 2005, Triumph introduced a redesigned Sprint ST based around the same inline triple, increased in stroke to yield a displacement of 1,050 cc (64 cu in) and with a new fuel injection system. The redesigned chassis found its wheelbase shortened, the instrument cluster was modernised with miles-per-gallon and miles-to-empty displays, exhaust pipes were tucked under the seat, the headlights were completely redesigned and LED tail-lights added, and a host of modern options including pannier mounts and anti-lock brakes (ABS 2006 onwards) became available.

In 2007, three features that were options in previous models became standard features: colour-matched panniers, handlebar risers and an improved windscreen. Coincidentally, with the demise of the Daytona in 2006, The sprint's tune became sportier. lifting the maximum torque point substantially to 7500rpm.

For 2008, changes included a steel fuel tank to allow the use of magnetic tank bags, a new headlamp design to improve night vision and new footrests that were claimed to be covered with more durable rubber. The Sprint's chassis, bodywork, and engine remained unchanged.

For 2009, the bike remained unchanged.[1]

Triumph Sprint GT 1050

For 2010, the Triumph Sprint GT was launched.[2] The GT (Grand Tourer) gained a new headlamp design identical to the ST losing the projection lamps in favour of a more conventional reflector-style set-up used on the earlier sprints. Hard panniers, increased by 9 litres (from 22 to 31) are being supplied as standard, with an optional 55 litre top box able to be obtained as a factory accessory. The GT features revised engine on an uprated ecu bringing the max torque point midway between its predecessors at 6,300 rpm and more intake and exhaust flow by elimination of the signature triple under seat exhaust in favor of a side-mounted 3-into-1 exhaust and revised throttle body intake, providing a more linear torque curve over the ST as well a small increase in horsepower (5 bhp as claimed by the factory). Additionally, the pillion footpegs have been repositioned and the seat reshaped to be more accommodating for carrying a passenger. The GT's overdrive gear is now 7 percent taller than the ST, allowing for more relaxed, sustained highway cruising, and lowering the engine speed to just over 4,000 rpm at a steady 110 km/h (68 mph). Suspension components were also changed, the front forks containing all new internal spring rates to better dampen the forward weight of the bike. Rear suspension is all new with a Showa shock featuring spring preload and rebound damping adjustability, the former being with a twist knob rather than a flat-head screwdriver. These new additions have added just over 7 kg (15 lb) to the weight of the bike, fully fuelled. Total ready-to-ride weight, from the factory, is 267.6 kg (590 lb). The GT also includes standard anti-lock brakes (ABS), a feature that was an option on the ST. In addition, the GT is slightly longer than the ST, with an overall length of 2260mm (89.0 inches) compared to the ST with 2114mm (83.2 inches) and a wheelbase for the GT of 1537mm (60.5 inches) compared to the ST at a smaller 1457mm (57.4 inches) adding to the ST's greater sporty feel compared with the more relaxed position and feel of the GT
