Lot 428: Norton Big 4

Grand Palais Sale, Bonhams (7 February 2013)

Having hitherto relied on proprietary engines, Norton introduced its own power unit in 1907. The long-stroke (82x120mm) sidevalve single displaced 633cc and the new model it powered became known as the 'Big 4'. Considered by many to be an ideal sidecar 'tug', the Big 4 (and its 490cc 16H sibling) would be continuously updated for the next 30-plus years, many seeing service with Allied forces in WW2. Post-war, the Big 4 was revised with a shorter (113mm) stroke for a capacity of 597cc before taking its final bow, alongside the16H, in 1954. Last insured for road use in 2005, this restored Big 4 is offered with French Carte Grise de collection. It should be noted that the engine number has been re-stamped.
