Triumph Motorcycles Ltd - Model Range

Model Range

A range of new 750 cc and 900 cc triple-cylinder bikes and 1000 cc and 1200 cc four-cylinder bikes were launched at the September 1990 Cologne Motorcycle Show. The motorcycles used famous model names from the glory days of Meriden Triumph and were first made available to the public between March (Trophy 1200 being the first) and September 1991. All used a modular liquid cooled DOHC engine design in a common large diameter steel backbone frame. The modular design was to ensure that a variety of models could be offered whilst keeping production costs under control – an idea originally put forward, in air-cooled form, in the early 1970s by Bert Hopwood but not implemented by the then BSA-Triumph company.

The first models, known generically as the 'T300's, all used a common piston diameter (76mm) in a common wet cylinder liner. Basic engine variations were achieved through the use of two specifications of piston stroke: 65mm to create individual cylinder capacity of 300cc, and 55mm to create a 250cc individual cylinder. Two 750cc models were released - and the Daytona and Trident 750 triples (3 x 250cc). There was one 1000cc model - the Daytona 1000 four (4 x 250cc). Two 900 cc models were the Trophy 900 and Trident 900 triples (3 x 300cc). The Trophy 1200 four was the largest model (4 x 300cc). All were remarkably smooth running. The three cylinder models were equipped with a contra-rotating balance shaft mounted at the front of the engine. The four cylinder models benefitted from twin balance shafts - unique at the time - mounted beneath the crank shaft. Contemporary road tests noted the solidity and smoothness of performance as positives but the weight of the machines as negatives. For brand new machines produced by a totally new concern, there were remarkably few early problems. These were an insecure oil pressure switch and a longer-lived problem with the starter (or 'sprag' clutch). The cosmetic finish on the first machines was simple and not very robust. Revisions to crankcases for the three-cylinder models in 1993, together with a move to high pressure casting, reduced engine weight considerably. All painting and plating operations were brought in house in 1993, as the Hinckley factory benefitted from further investment after the initial success of the range. The result was improved quality and durability of finish, added to the basic engineering integrity of the engine and chassis, made for a long-lasting and robust motorcycle.

The range was largely revised in 1997 with the release of the T500 range, followed by a light-weight four-cylinder 600 cc sports TT600. The 600 was a major design departure and initially received a poor press: "unpleasant at low revs due to a lethargic and unpredictable throttle response, with anonymous styling". As sales built, the big fours were phased out of the lineup and parallel twins and triples became the marketing and development focus of Triumph's marketing strategy. Triumph also decided to exploit demand for retro motorcycles with modern engineering. The Triumph Thunderbird 900 exploited the styling cues of the 'old' Triumph's legendary designer, Edward Turner whilst retaining the modern triple engine. The 790 and 865 cc versions of the Triumph Bonneville and Thruxton look and sound original but internally they have modern valves and counterbalance shafts.

For their contemporary range, the triple is Hinckley Triumph's trademark, filling a niche between European and American twins and four-cylinder Japanese machinery. The 2,294 cc (140.0 cu in) triple Rocket III cruiser was introduced in 2004. The first 300 Rocket III models were already sold before they were produced, and there was a long waiting list for Rockets into 2005.

On 21 July 2008, Triumph held a Global Dealer Conference where new models for 2009 were launched, including the official announcement of the parallel twin-cylinder Thunderbird.

Triumph's best selling bike is the 675 cc Street Triple. In 2010 they launched the Triumph Tiger 800 and Tiger 800 XC, dual-sport motorcycles, which uses an 800 cc engine derived from the Street Triple, and is designed to compete directly with the market leading BMW F800GS. In 2012, the Tiger 800 was joined by the shaft-driven Triumph Tiger Explorer.
