"When I took over Triumph in 1936 it was my intention to introduce a vertical 500 twin and in 1938 I offered one to the general public known as the 'Speed Twin' which was an entirely new mechanical layout. The general proportions of this engine were most eyeable (sic) and in performance it was even more remarkable inasmuch that the first prototype was producing nearly 30 horsepower." – Edward Turner.
The Speed Twin offered here dates from 1951, by which time the model had been upgraded with a stronger 8-stud cylinder barrel (replacing the original 6-stud) and Triumph's own telescopic front fork. This particular machine also has the Edward Turner-designed optional 'Sprung Hub', which endowed the rigid frame with a measure of rear suspension movement.
Previously registered in Jersey as 'MUO 69' (in 1978), this Speed Twin was first registered in the Isle of Man in March 2000 and comes with its IoM registration document issued in 2009. Now fully restored throughout, the machine was last taxed until 31st May 2011 and had 321 miles showing on the odometer at time of cataloguing. Additional paperwork includes a quantity of invoices dating from 1998; a Sussex British Motor Cycle Owners Club dating certificate; a Triumph replacement parts catalogue; and Bryan Small's restoration invoice totalling £8,776.
