Vehicle Information
Triumph Speedmaster Motorcycle - Street (2003-2021)
The Triumph Speedmaster, a British custom-style cruiser motorcycle, was produced from 2003 to 2021. Over these years, it underwent significant engine and platform evolutions, establishing itself as a distinctive model within Triumph's lineup. Initially launched with a 790cc air-cooled parallel-twin engine (2003-2004), its displacement increased to 865cc in 2005. A key update in 2008 introduced electronic fuel injection (EFI) to the 865cc engine, improving performance and emissions. The most significant transformation occurred in 2018, with a complete redesign and the adoption of a powerful 1200cc liquid-cooled engine, along with modern features like ABS and traction control, rebranding it as the "Bonneville Speedmaster". Throughout its production, the Speedmaster was generally offered as a single model, with variations primarily in color schemes and optional accessories rather than distinct mechanical trims. Q: How do I ensure I select the correct parts for my Speedmaster?
A: Please use the year and edition selector on this page to find parts specifically compatible with your motorcycle's model year.
