Triumph Sprint ST
The Triumph Sprint ST is a sport touring motorcycle manufactured in the United Kingdom since 1999 by Triumph.
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) and 100 N·m (74 ft·lbf) of torque from a lighter engine—the bike is 207 kg (460 lb) dry.
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.
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.
For 2010, the Triumph Sprint GT was launched. The GT (Grand Tourer) gained a new headlamp design identical to the ST losing the projection lamps in favour a more conventional reflector-style set-up. 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 mapping and elimination of the signature triple undertail exhaust in favor of a side-mounted 3-into-1 exhaust, 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.
