Lot 023: 1974 BSA A65 LIGHTNING

1971 wittnessed the introduction of a new oil bearing frame for both the BSA and Triumph twin cylinder ranges. Developed at Umberslade Hall, the new chassis incorporated internally sprung slimline forks, revised brakes and amended styling. Towards the end of BSA's activities as a manufacturer of motorcycles the company developed at the request of their American arm, a "longstroke" engine displacing approximately 750cc. Intended to provide a powerplant for the company's US flat track racing team, 200 machines were produced for homologation purposes and in doing so provided the inspiration for firms such as Devimead who subsequently offered "Jumbo" conversions for the A65 powerplant. This late example of the Lightning has benefited from Devimead's attentions and perhaps surprisingly, given the 754cc displacement, is described by the vendor as being the smoothest A65 he has ridden. It should be noted that the previous owner, when commissioning the work from Devimead chose to use a new set of un-numbered crankcases rather than modify the originals which are included with the machine as receipts for the work carried out to the engine. The bike is equipped with electronic ignition and has recently been fitted with new tyres and chains during an overhaul carried out by Minovation Racing. It is supplied with a Swansea V5C.
