1955 Norton Featherbed, built to exacting standards by an aircraft engineer/ inspector. Model 50 engine built by Mike Pemberton of Pushrod Performance with the cylinder head originally fitted to that engine modified with larger valves and a squish band among other details. The Engine is based on the 350 flywheel assembly with a stroke of 88mm, to which is fitted an 87mm barrel as opposed to the original 71mm barrel. Capacity thus rises from 350cc to 520cc. so the Mike Pemberton engine is much the same size but with shorter stroke and lighter flywheels.
