Description
Like the majority of their contemporaries, Norton relied on the
sidevalve engine until the 1920's, when the existing and well-tried
490cc unit was used as a basis for the firm's first overhead-valve
design. Penned by James Lansdowne Norton himself, and first seen
in prototype form in 1922, the overhead-valve Norton made little
impact in that year's Senior TT, though at Brooklands D.R.O' Donovan raised the world 500cc kilometre record to over 89 mph using the new motor. A road-going-version -the Model 18- was catalogued for 1923, quickly establishing a reputation for both speed and reliability when a standard engine assembled from parts was used to set a host of records, including a new 12 hours mark. Racing continued to improve the breed -when Alec Bennet won the Senior TT for Norton- as a direct result of the works team's experiences.
