The "Road-Holder" for 1939

-built to the most exacting requirements of the connoisseur

"FIRST AGAIN!" - these two words, so persistently associated with NORTON motor cycles over a long period of years, summarise the superiority of "The Road-Holder." Thoughtful motor cyclists will appreciate, too, that this is no mere superficial expression of superiority but that the significance of NORTON racing successes has a direct bearing on the performance of every model in the "Road-Holder" range.

To achieve what NORTON machines and riders did in the 1938 T.T. races is to provide a marvellous demonstration of speed over a difficult course, but more than that, it provides unrivalled proof of reliability. In the Junior Tourist Trophy Race the NORTON team, consisting of F. Frith, H. L. Daniell and J. H. White, won the Manufacturers' Team prize for the fourth successive year - a brilliant repetition of 100% reliability. In the Senior T.T., won by H. L. Daniell at the magnificent record speed of 89.11 m.p.h., with a wonderful record lap of 91 m.p.h., F. Frith finished third at 88.98 m.p.h., and J. H. White was fourth at 87.14 m.p.h. And so for the seventh time in eight years a NORTON was "First Again ! " in the Senior T.T. and for the fifth time in six years the NORTON team won the Senior Manufacturers' Team Prize. Never in the whole history of motor cycling has such a wonderful demonstration of reliability been staged as in the long sequence of NORTON successes.

Turning to the classic Reliability Trials one finds a similar preponderance of NORTON successes so that whether it is fast road-work or "mud-slogging" and negotiating steep and rocky gradients, "The Road-Holder" is equally at home. It is evident, therefore, from the proof put before motor cyclists, that NORTON brilliance of design, consistent perfection of materials used, superlative workmanship and unfailing reliability surpass anything so far achieved.

This is what you get when you choose from the "Road-Holder" range - the best that money can buy - and this, as has been proved time and time again, is always true economy.


IMPROVEMENTS FOR 1939

1. An improved oil control ring is fitted to the pistons of all engines. This, in conjunction with an increased number of oil holes in the piston, tends to still further reduce oil consumption.

2. On all models an improved silencer of tubular construction is fitted. This more effectively reduces the exhaust noise and is pleasing in appearance. The gases pass into the silencer body through a perforated tube which is fitted with a spiral baffle and out into the atmosphere through a tail pipe. This is of slightly smaller diameter and similarly perforated and baffled.

3. On all models with the exception of the International type the saddle position has been modified to give a more resilient mounting. Furthermore, the saddle itself has been increased in size, which considerably adds to the rider's comfort.

4. On all models the front brake is now mounted on the offside of the machine. This gives improved controllability, as well as providing a more direct speedometer drive.

5. The tyre inflator has been removed from the tank and is now fitted on the rear chainguard, where it is adequately protected from mud by a neatly formed shield.

6. On all models except International type the enamelled tank panel has been improved. The characteristic NORTON tank colours are retained.

7. On the E.S.2 model an International type petrol tank is now available at an extra cost of £1 10s. 0d. The capacity of this is approximately 3½ gallons.

8. On Models 30 and 40 a spring frame can be incorporated, identical with that used in the 1938 Tourist Trophy Races but with slight modifications, at an extra charge of £7 10s 0d. This is also now available on the E.S.2 machine at the same extra charge.

9. On all models the aluminium panel cover and magneto chain cover is polished finish in lieu of sand blasting, the remaining part of the case being sand blast as before.

10. The end cover of the gearbox and change speed mechanism cover is polished instead of sand blast. This considerably improves the appearance of the machine.
