Norton 1933 Model 18 490 cc OHV single frame # 48379 engine # 54781
In 1921 Norton Motors moved into new premises in Bracebridge Street, Birmingham.
The model range consisted of two simple, sturdy and beautifully finished side valve three speeders, the 490 cc model 16/17 and the 633 cc “Big 4”, and three direct belt drivers, very fast but rather outdated now and really only of interest to the real speed enthusiast.
In 1923 the first OHV model Norton was brought out, the 490 cc Model 18.
By 1933 there were OHV models in capacities of 348, 490 and 596 cc.
Most popular was the 490 cc class, with bore and stroke dimensions just as they were in 1911, 79x100mm. With these models the pushrods and overhead rocker gear are enclosed, but the valve springs are nice out in the open.
The OHV model ES2 has the springs enclosed, hence Enclosed Springs 2.
This fast touring machine has the optional 4 speed foot gear change. The machine is in restored condition.
