Triumph has given its Street Triple and Street Triple R models a comprehensive makeover for the 2011 season.

The new models feature detail and visual improvements, including the adoption of the headlight design shared with the iconic Speed Triple.

As well as the aggressively-styled headlights, the Street Triples have been given a more contemporary look and higher quality feel.

New colour options and sporting graphics give the class leading middleweight a new look. Both models feature the new style Triumph sports script on the tank, debuted on the new Daytona 675R, as well as a stylish new ‘Street Triple 675’ logo.

The standard model features three metallic paint options at no extra cost (Crystal White, Phantom Black and the distinctive new Imperial Purple), with the higher-specification ‘R’ available in Diablo Red, Crystal White and Phantom Black (with gold wheels).

Both models have been ‘dechromed’ with brushed steel exhaust headers, heel guards and silencers replacing the previous polished items, with new handlebar clamps, machined detail on the handlebar end weights and redesigned headstock infills. The standard model also benefits from the same aluminium handlebars, as fitted to the Street Triple R, while both variants have Triumph’s latest specification instrument pack.

Mechanically the 2012 Street Triples remain unchanged, with 675cc three-cylinder engines. Both the Street Triple and Street Triple R share the same lightweight frame which, like the engine, is derived from the Daytona 675 supersport machine. The Street Triple R is further enhanced by higher-specification, race-track inspired brakes and suspension.

The Street Triple and Street Triple R will arrive in UK Triumph dealers this month, priced at £6,649 OTR and £7,349 OTR respectively.
