Triumph Speed Triple 1050 Service Manual (2005-2010)

Triumph introduced the Speed Triple 1050 for the 2005 model year, marking one of the most important changes in the model's development. The original Speed Triple had established Triumph's factory streetfighter identity in 1994, but the 2005 motorcycle increased engine capacity from 955 cc to 1,050 cc and developed a more distinctive standalone design rather than sharing much of its bodywork with Triumph's sports models. Triumph itself describes the 2005 Speed Triple 1050 as a model that reset the benchmark for the naked performance category.

The larger engine retained Triumph's characteristic inline-three layout but increased stroke to 71.4 mm, producing 130 PS and 105 Nm in the factory service specification. The new generation also adopted upside-down forks, radial-mounted front brake calipers, an aluminium twin-spar frame and a single-sided swingarm. Combined with the twin headlights and compact rear bodywork, these elements established the visual and mechanical formula that came to define the modern Speed Triple.

Triumph continued developing this generation during its production life. For 2008, the Speed Triple received a substantial update including Brembo front brake calipers and radial master cylinder, redesigned wheels, black-anodised Showa forks, tapered Magura handlebars, revised rear bodywork and other styling changes. Triumph later celebrated the model's 15th anniversary with a special edition introduced for 2009. These updates remained within the same VIN-based 1050 generation rather than constituting the completely redesigned model that followed.

The major generational break came with the 2011 Speed Triple, beginning at VIN 461332. Triumph's parts documentation identifies the preceding 1050 generation as VIN 210445-461331, and T3856080 is the service manual assigned to that range. This is why the attached manual should be catalogued as 2005-2010, rather than the current 2005-2015. Later Speed Triple models require the post-VIN-461332 service publication.
