An unusually long brake pedal is standardised. This is provided with a special stop so that the pedal may be adjusted in relation to the footrest. Note also the prop stand.
An overhead valve push-rod operated 490 c.c. engine and a cradle frame are fitted to the E.S.2.
A feature of the rubber-mounted Lucas battery is its accessibility.
For 1937 all Norton machines, other than the "Internationals," have a new riding position and 7/8in. diameter handle-bars.
Almost as famous in its own sphere as the "Internationals" is the Model 1. 633 c.c. side-valve Norton - specified above.
"International 30" Model—490 c.c. single-cylinder o.h.c. Norton; dry-sump lubrication; magneto ignition; all-chain drive; oil bath primary chain case; 4-speed gear with foot control: fuel. 3¾ gals.; 3.00x21 (front), 3.23 x 20 (rear) tyres.
Everyone who went to Olympia made for the Norton stand. The "International" models, which are the production models of the machine which have done so much to uphold British racing prestige on the Continent, are arousing considerable interest. The over-head-camshaft engines have changed but little in outward appearance. However, the cradle frame has been modified at the front end by an upsweep which not only increased the ground clearance but also improves the appearance. Except for engine size the two "International" models are almost identical.
Only one push-rod engine is mounted in the cradle frame - the model ES2.
Much of the knowledge gained from racing experience is incorporated in all Norton models, but in the "International" models it is particularly evident.
The 490 c.c. Model 18 is typical of the push-rod models. It has a diamond frame and a single-port engine. The generously finned cylinder head and barrel are secured to the crank case by long holding-down bolts. It has counterparts in the 596 c.c. Model 19.
Chief among the alterations to the famous Model 1. 633 c.c. side-valve model are the modifications in the riding position.
All Nortons except the "Intenatlonals" have improved riding positions with lower saddles and "natural-angle" handle-bars. Lucas electrical equipment with voltage control, and improved clutch operation are other important features. Larger oil tanks are fitted.
Model 1. 633 c.c. single-cyl. side-valve Norton; dry-sump lubrication; magneto ignition; all-chain drive; oil-bath primary chain case; 4 speed-gear with optional control; fuel, 2 ¾ gals: 3.25x19 tyres.
In addition to a good turn of speed, they are well known for their low-speed pulling, and few machines have such a high reputation as the "Big Four" for heavy sidecar work.
As with all Nortons, the specification includes oil-bath primary chain case, rubber-mounted handlebars, and many other useful features.
This model is particularly suited for Colonial commercial conditions and sells at £ll6/10/ complete with lights and includes Sales Tax.
