The Speed Triple was released to the public in 1994, with its name serving as an acknowledgement of the 1938 Speed Twin. The model was based on the Triumph Triple modular engine series, which also powered the Trident, Daytona, and Thunderbird. The streetfighter styling—characterized by a sport bike chassis stripped of aerodynamic plastic fairings—was inspired by bikers who repaired crashed race replicas by returning them to the road without bodywork.
The initial T300 series utilized carburetted 885 cc water-cooled engines and a five-speed transmission, though later versions were upgraded to six-speed units. A limited run of 750 cc machines was produced in 1997 using leftover European specification engines. These early models featured a large single steel tube backbone frame with the engine acting as a stressed member. The suspension consisted of 43mm multi-adjustable Kayaba forks and a rear monoshock with a progressive linkage.
In 1997, Triumph introduced the T509, a complete redesign featuring fuel injection and a SAGEM engine management system. Designed by John Mockett and Rod Scivyer, the T509 moved to an aluminium perimeter chassis and a single-sided swingarm. While the engine remained at 885 cc, it produced a claimed 108 hp. The bike was notable for its dual headlamps and a polished frame.
The model was officially upgraded to the 955 cc engine in 1999. By 2000, the series adopted the "955i" designation to align with the Daytona. A 2002 redesign by Gareth Davies reduced the bike's weight by approximately 17 pounds through new engine casings. Despite its performance, the 1997–2004 models were noted for problematic Nissin brakes; inadequately coated caliper pistons often caused a "spongy" feel due to dirt and corrosion.
The fourth-generation Speed Triple, designed by Rodolfo Frascoli, debuted in 2005 with a displacement increase to 1,050 cc via a lengthened stroke. This version introduced Keihin fuel injection, inverted forks, and radial disc brake calipers. In 2008, the model received Brembo front brakes as standard and transitioned from a plastic to a metal fuel tank.
A major update in 2016 introduced 104 engine changes and ride-by-wire technology, offering five ride modes, traction control, and switchable ABS. This iteration developed a claimed 140 hp and 82.6 lb⋅ft of torque. To mark the model's fifteenth anniversary in 2010, Triumph released a limited-edition version featuring the signature of company owner John Bloor.
In 2021, the series was redesigned as the 1200 RS, featuring a new 1160 cc inline three engine. This unit increased output to 177 hp and 125 Nm of torque while reducing the wet weight to 198 kg.
In 2022, Triumph introduced the 1200 RR, a road-oriented sport bike variant with café racer design cues. The RR features a single round headlight, a bikini half-fairing, and a more aggressive riding position with clip-on handlebars and rearward-set foot pegs. It also incorporates electronically adjustable semi-automatic Öhlins suspension.
The Speed Triple's evolution is marked by a consistent increase in power and a reduction in weight relative to displacement. The original 1994 885 cc model transitioned through the 108 hp T509 and the 130 hp Daytona-derived 955i units, eventually reaching 177 hp with the 2021 1200 RS. By 2010, the model had achieved a production milestone of 35,000 units, cementing its place as a core component of the Hinckley Triumph lineup alongside the Sprint and Tiger series.
