First Jugoslav Racer in Britain -December 1964
THE first racing machine to be imported into Britain from Jugoslavia shattered the winter quietness of Oulton Park last week. It was a five-speed 50 cc Tomos two-stroke recently acquired by Bolton, Lancashire, dealer John Pomfret.
Father of a schoolboy road racer who, at the tender age of 16, is the lucky owner of a double-knocker 50cc Honda, he plans to import the 50 cc Tomos for sale in this country at well under £200.  His son, Mike Pomfret, will probably race one of the Tomos two-strokes next season. And there is a possibility that we shall see seven or eight speed Tomos in the 50cc TT race, next June.
Description
Initial tests of a somewhat under geared five-speed racer, in far from favourable conditions, suggest a competitive potential which if this promise is fulfilled, could give 50cc clubman racing a new lease of life "
Although there have been stories of a disc-valve Tomos engine, the Pomfret machine has a simple 49 cc ported two-stroke engine. The alloy cylinder has a chromed bore and a very well made expansion chamber exhaust system.

No rev-counter was fitted but, Pomfret was told the engines are virtually unburstable and able to exceed 10.000 rpm with safety. A claim of 8 bhp at 8,500rpm cannot be confirmed but the Oulton outing indicated useful power at high revs.
Since the engine was brand new,the largest available jet was fitted to a 30 mm down-draught Dell’Orto carburettor. The track was wet but both Dennis Holden, an experienced racer, and Motor Cycle News staff man, Sean Wood, whose starting technique consisted of paddling with both feet, reported a useful power band.
Fitted with an air lever and ignition cut out button, the Tomos production racer is based on standard 50cc moped manufactured in a modern state-owned installation at Koper, a fishing village on the Adriatic. This firm also makes 2CV Citroen cars under licence.
A pressed steel frame and other cycle–parts are moped components but the engine-gearbox unit, featuring a geared primary drive and an outsize clutch mechanism, is designed especially for racing.  Steel rimmed wheels have neat alloy brakes and 2.00 by 19 Continental tyres. Overall weight, complete with a slick little fairing is only 98 lbs.

While performance was thought to be faster than an Itom, the Tomos was probably a shade slower than a Honda. Not surprisingly, streamlining proved vital. A rider peering over the screen was enough to knock several miles per hour off the top speed estimated at 75 to 80 mph. The makers claim 83mph as the top speed.
Whether or not the Tomos race will be welcomed by 50cc fans in the UK depends largely upon what Pomfret and his son can get out of samples obtained after a 1450 miles journey to Jugoslavia.

TAKE the beautifully styled dolphin fairing away from the little Tomos racer, and the machine would look almost insignificant.
But here is the secret of the Yugoslavian newcomer it is not a sheep in wolf's clothing as are many so-called racers in its class, but just the opposite. It is the engine that makes a bike go and the Tomos is equipped with one of the most powerful egg-cup buzz boxes on the scene. The five speed box, how-ever, is a necessary luxury, for the little Jugoslavian flyer has a very pronounced power band.
No rev counter was fitted to the prototype I tried at Oulton Park, so it is impossible to tell exactly when the power came in, but one thing is for sure, you've got to keep it on the boil. Let the revs fall too much and the bike feels as though it's running out of fuel, open the throttle and nothing happens. Then, just as the uninitiated rider starts searching for the petrol tap, a sudden surge of power sends the little beast shooting forward at a remarkable rate of knots. Then you’re away!
Eighty MPH
Estimated maximum speed of the Tomos, which fired for the first time a few minutes before I took it round the Cheshire circuit, is between 75 and 80 mph. Better than most, if not quite on terms with the Japanese Honda production racers. But remember this is in standard form. It is not even fitted with alloy rims, and the tank is of steel. Riding the bike was a sheer pleasure. The position, while providing ample opportunity to employ a racing crouch, is a compromise and not excessively uncomfortable.
Handling on the wet track was excellent, despite the non-racing tyres and the brakes were wholly adequate. The gear lever is mounted on the left of the bike, and moves one down, four up. An unusual feature is the air lever mounted on the right clip-on. Seeing as the machine at Oulton was brand new, it was run with the lever half open, half closed to offset any likelihood of a seizure. It is also useful, of course, for cold starting and varying weather conditions.
Quick gear changes on a bike with so critical a power band are essential. This fact has not gone unnoticed by the Jugoslav factory, and to make super-fast cog-swopping easier, they have provided the racer with an ignition cut-out button, MZ fashion, so the clutch need not be used except, of course, for starting.
The Jugoslav factory have told Mr. Pomfret, the Bolton dealer, who intends to import the Tomos, that the racer will run, trouble free, for two years. It could be the answer to 50 cc racing enthusiasts’ dreams. It is faster than the best Italy can offer and will be about £150 cheaper than the now discontinued Hondas. With a little work, who can tell? It might beat the Hondas!
