“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,” Motor Cycling enthused 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. The current owner acquired this restored Viper in part exchange for a vintage car, its previous history being unknown. We are advised that the engine was overhauled by Velocette specialists Vulcan Services in 2004/05 and fitted with the factory crankcase breather modification. Other upgrades include a Criterion 12-volt alternator driven by toothed rubber belt; Boyer Bransden power box control unit; and Vulcan electronic ignition with auto/manual control. The machine, which has been ridden in the 2005 Southern Irish Rally and local club events, is offered with current road fund licence, MoT to June 2006 and Swansea V5 registration document.
