1921 New Imperial 250cc Racing Motorcycle
Registration no. OH 6926

After an abortive attempt in 1901, New Imperial commenced series production of motorcycles in 1910. By 1913 the fledgling firm was contesting the Isle of Man TT races, entering a trio of 500s in the Senior event, none of which finished. This disappointment and the intervention of WWI delayed New Imperials next appearance until 1921, but what an historic return it would be. At that time there was no separate Lightweight TT race (the 250s would not have their own separate Lightweight TT race until 1922); instead a trophy was awarded for 250cc machines entered in the Junior (350cc) event, the first such award having been made in 1920 when Levis secured a resounding victory, taking the first three places. New Imperial entered five JAP-engined 250s in the 1921 Junior and although four retired, Douglas Prentices went on to win the class at an average speed of 44.82mph, Bert Kershaws having set the fastest lap.
New recruit Bert Le Vack came close to victory in the Junior event the following year and finished second in the Lightweight race in 1923, and then the Twemlow brothers 1924 Junior/Lightweight TT double - Ken winning the former, Eddie the latter - plus Eddies repeated Lightweight victory in 1925, confirmed New Imperial as one of the dominant forces in 250 racing in the Vintage years. New Imperial had switched from JAP to engines of its own manufacture by the decades end, and although the 1930s brought fewer success in the Isle of Man TT, Bob Fosters 1936 Lightweight TT win was notable as the last achieved by a British-made machine.
The machine we offer is Douglas Prentices 1921 Junior 250cc Trophy-winning machine, which comes with his signed letter of authenticity, dated 23rd August 1924, confirming that it was this actual motorcycle that he rode in the 1921 race. It should be noted that photographs in the Keig archive show Doug Prentice (No. 24) astride OH 6924 before the race and his team-mate Les Horton (No. 20) on OH 6926 at the start. However, it was common practice for race teams to swap frames, engines and registration plates as and when it suited them. Interestingly, Prentice was photographed by Keig prior to the 1922 race aboard a works New Imperial registered OE 250, a registration issued in 1919/1920. Furthermore, although it is partially obscured in Keigs start-line photograph, this may well have been the registration that Prentices bike carried during the 1921 race! It most definitely is not OH 6924 on which he had been photographed during practice. New Imperial does seem to have had a somewhat casual attitude to registrations! It should also be remembered that Prentice authenticated OH 6926 in 1924, a mere three years after the 1921 race, and again some 40 years later. Of equal significance is the fact that Prentices machine had been given to him after the race by New Imperial boss Norman Downs (see below).
Also contained within this historic machines accompanying file are two old-style buff logbooks, the earliest of which (issued January 1925) records one Reginald Wright, of Kidderminster, as the sole owner. (The aforementioned letter is on headed notepaper belonging to J Wright & Sons, of Kidderminster, suggesting that the machine passed directly from Doug Prentice to Mr Wright). Mr Wright appears as owner in the second book (issued September 1954) and John Bone as 1st Change from October that same year. One of the founding committee members of the VMCCs North Birmingham Section, John Bone owned OH 6926 until his death in 2006 and the machine is now offered for sale by his family.
In August 1961 John Bone corresponded with Doug Prentice, whose accompanying letters reveal that the Trophy-winning machine was given to him by Mr Downs of New Imps (company founder Norman T Downs). Doug Prentice states that the bike never gave him the slightest trouble either in the Isle of Man where I did countless practice laps prior to the official practice period, in the Race itself, or during the English Six Days Trials where it gained a Gold (after changing the TT close ratio box!). He also states that while other members of the 1921 team changed valve springs prior to the actual race, he decided to leave well alone and ended up the only New Imp finisher. Sadly, Doug Prentice died in September 1961 without having had the opportunity to see his old bike again.
John Bone used the TT-winning New Imp extensively on VMCC and other events throughout the late 1950s and into the 1960s, including three successive Lands End to John OGroats runs (1959-61) for which he was awarded the Vintage Invincible Triple Trophy. The latter is included in the sale together with a substantial quantity of other trophies and commemorative awards (list available). The 1954 bill of sale, an old MoT certificate (expired August 1974), owners notes, assorted press cuttings and various period photographs are contained within the accompanying history file, close inspection of which is recommended.
Last taxed for road use in 1977, OH 6926 was restored circa 1988 and has been looked after by Geoff Bishop for the past nine years and prior to that by retired engineer, Bernie Hill. Started occasionally since it was last used, the machine will nevertheless require re-commissioning and the customary safety checks before returning to the road.
Including the winners of the Junior 250 Trophy, only 38 motorcycles won Isle of Man TT races during the Vintage period; thus OH 6926 represents a rare, possibly once-in-a-lifetime, opportunity to acquire an historic machine belonging to this most exclusive category.
