Dirt track (speedway) racing arrived in the UK in 1928 from Australia, the first make of motorcycle to achieve dominance on the cinders being Douglas. Before long, every manufacturer had to have a speedway or dirt track model in the range. Listed for the 1930 model year only, Sunbeam's 'DTR' was powered by the Model 90 racing engine, which was housed in a shortened frame fitted with road-type Druid forks, though these were soon ditched in favour of the specialised Webb speedway type. It is not known how many DTRs were made, though given the model's short production life it cannot have been very many. This example of one of the rarest of speedway motorcycles was restored in 2011 and is described as in generally good condition.
