'A brief run on the red and two-tone grey "EMC" proved the point that a two-stroke multi is out on its own for smoothness,' declared Motor Cycle's tester, David Dixon. The EMC cycle parts were left relatively standard, except for the substitution of a BSA 7" front brake for the original. As the Excelsior engine/gearbox unit was intended for car use, a reverse gear is incorporated, which is engaged by moving a hand lever and selecting 1st in the Burman 'box. The front gearbox remains in 1st gear and changes are made using the Burman four-speeder. Aligning the gearbox and rear wheel sprocket would have meant moving the engine way over to the right, unbalancing the machine, so David opted to interpose a second (Burman) gearbox behind the engine to achieve the necessary chain alignment. Excelsior's triple produced a claimed 30bhp and boasted the added convenience of a SIBA electric starter, though having to find space for the largish 12-volt battery necessitated fabricating a special under-seat mounting.Įarly on a major problem was encountered when the engine was offered up to the frame: the rear chain line was miles out, a problem all too frequently encountered by builders of specials. This unique hybrid consists of a 1953 EMC frame and a 492cc Excelsior three-cylinder engine, bought new from the factory, of the same type supplied to Berkeley for their three-wheeled SE492 sports car (purchase receipt on file). Amazingly, David had only commenced constructing his latest special in 1962 so to have it roadworthy by the following summer was an outstanding achievement.
Less than 12 months after his BSA-Anzani special (Lot 345) had featured in Motor Cycle, David Blanchard was back in the magazine again when his unique EMC-Excelsior triple featured on the front cover of the 4th July 1963 edition.
