Triumph has been bolstering their line-up of motorcycles at a steady pace over the last few years, drawing on their classic designs with machines such as the Scrambler while also offering cutting-edge bikes that compete with the best from the rest of the world, like the 675. There is a rather large gap right now in between their Bonneville line and the monster Rocket III. Spy shots seem to indicate that this missing link will soon be found in the form of a liquid-cooled parallel twin-powered cruiser. Although our only photo evidence is the grainy image on the right, we can clearly see that a styling link exists between the Bonneville retro-bike and this new machine, which some are suggesting will be known as the "Speed Twin".

Rumors that the engine will fall somewhere around 1700cc and punch out triple horsepower and torque figures. If you are interested in the idea of a Triumph Big Twin to compete with Harley and the metric brands, get your checkbook ready for what will likely be a 2009 model year launch.
