DOT (Dover Transport Office) was a British motorcycle manufacturer that was founded in 1922 by Bill Lacey.
The company was known for producing high-quality, reliable motorcycles that were popular with both commuters and sports riders.In the 1950s, DOT began producing trials motorcycles, which were designed to be capable of tackling tough off-road terrain. These bikes were powered by single-cylinder engines and featured lightweight frames, making them agile and capable on the trails.
Throughout the 1960s and 1970s, DOT continued to develop its range of trials bikes, introducing a number of new models including the Comet, the Meteor, and the Super Meteor. These bikes were popular with riders looking for reliable and capable machines for tackling challenging trials terrain.
In the 1980s, DOT was acquired by the British company Armstrong, and production of its trials bikes came to an end. However, the company´s legacy as a producer of high-quality trials motorcycles lives on, and its bikes are still highly sought after by collectors and enthusiasts.
