Norton 1927 Model 18 490 cc OHV single frame # 15353 engine # 34018
|By the end of 1922 the first OHV model Norton was brought out, the 490 cc Model 18.
At its introduction it got the factory code word of “Speedy”, which certainly showed some foresight: speeds up to 100 mph were attainable with carefully tuned engines. In the course of 1923 a number of speed events were won, but in 1924 the Model 18 really showed what it was capable of.
In June Alec Bennett won the senior TT on a model 18 with an average speed of 61.64 mph; the sidecar TT was won by George Tucker on a 588 cc version of the model.
Both the French and Belgian GPs were won, and Bert Denley captured the coveted British One Hour Record at 87.07 mph.
In 1925 a new drum brake and Webb centre spring forks were featured; in 1926 the Model 18 got a mechanical oil pump which was fitted to the magneto drive cover.
This magnificent sports OHV is in good mechanical condition
