'One's outstanding impression is of the exceptional flexibility and smoothness of the engine - it seems almost incredible that so much docile punch should be the product of no more than one cylinder and an 8.5:1 compression ratio,' enthused Motor Cycling about its test Viper, summarising characteristics that will be familiar to anyone who has ever ridden one of Hall Green's delightful high-camshaft singles.

Engine development pursued as part of the MSS scrambles programme bore fruit in 1956 in the shape of the high-performance 500cc Venom and its 350cc sibling, the Viper. The MSS frame and forks were retained for the newcomers but full-width alloy hubs were adopted to boost braking power and smart chromed mudguards fitted to enhance the models' sporting image. In 1960 'Clubman' versions of both were introduced, minus the enclosure panels of the standard models, which featured a raised compression ratio, Amal TT carburettor, 'racing' magneto, rear-set footrests and a close-ratio gearbox among many other improvements.

This Viper had been in long-term ownership prior to the current private vendors acquisition in 2021. The Velo has been dry stored since. Following a period of inactivity, this motorcycle will require recommissioning and/or restoration to a greater or lesser extent before returning to the road and thus is sold strictly as viewed. Prospective purchasers must satisfy themselves with regard to this motorcycle's history, originality, authenticity, mechanical condition, mileage and completeness (or otherwise) prior to bidding.

Accompanying paperwork consists of a V5C Registration Certificate; tax reminders; DVLA correspondence; and a 2021 receipt for a new battery. Two books on the Velocette marque are offered with the Viper, including Velocette - Always In The Picture by Burgess & Clew and Velocetter - An Illustrated Profile of Model 1905 - 1971 by Dave Masters.
