RIDING THE DUCATI 500 NOT ONES TO SIT BACK and rest on their laurels, they being the Berliner Motor Corp. in New Jersey, their laurels being an already excellent line of 50cc, 150cc, 250cc, and the new 350cc and 1260cc Ducatis, now comes the welcome news of a new Ducati 500.
CRACKS I have a I960 Triumph TR-6 and have encountered cracks in the alloy head. These cracks run from the center four stud holes to the valve seats. While doing repairs on a '62 Bonneville I noticed the head was also cracked. Is this just a coincidence or does Triumph have a weak spot here? Will these cracks cause any trouble?

A FUNNY THING happened as we were preparing to go to Daytona this year. The editor had decided that the race track itself would be a perfect observation post for your roving reporter, and in due course we sent in an entry for the Expert/ Amateur 100-mile event for 250cc-class motorcycles. On the basis of my experience with the AFM road racing club, the AMA had given me an "Amateur" competition license; and we had a Ducati Diana 5-speed to convert into a proper racing machine.
Points piled up in the American Grand Prix put Suzuki in the lead for another World Championship trophy from the International Motorcycle Federation in 1965. 1962-Suzuki 50cc proclaimed Champion du Monde (World Champion) by the Federation Internationale Motorcycliste.
ENTER THE CRIES OF ANGUISH . . . Your opening statement to "A Look At Motorcycle Engines" (April CW) prompted me to write. I agree that motorcycle engines are too noisy, expensive and have a relatively short life, and wonder why someone hasn't seen fit to experiment with steam powered cycles. The idea isn't original with me; back in the 1870's a fellow made himself a steam bicycle which, according to one source, was a marvel of compactness and had a top speed of 60 mph. More recently, another steam enthusiast fitted an antique steam car engine into a Harley-Davidson. Top speed in this case was around 90 mph. Neither bike was fast by Triumph, Norton or BSA standards, but one was homemade about 90 years ago, and the other was an adaptation of a 50-year-old engine. There may be many more examples but these two at least prove it is possible. With modern engineering, bearings, manufacturing techniques and lightweight metals, it becomes not only possible but practical as well.
A NICE ASPECT of the motorcycle business is that new models are introduced when they are ready, and not just at some arbitrarily-established "new model" season — as is the prevailing practice in the automobile game. We find this stimulating, for one never knows (well, hardly ever) when something new and interesting will suddenly burst into the limelight.
OUR FIRST ENCOUNTER with the 350cc BSA single cylinder motorcycle was in July of 1963 when we tested the SS-90. The latest was a meeting with the truly charming little Enduro Star; so named because the machine is designed primarily for enduro competition.
SOON TO BE available in the United States is the new White 250cc single-cylinder, two-cycle motorcycle in three forms. CYCLE WORLD'S test staff was offered the advantage of riding the first model of two scrambler versions by Jack White, Maico importer and head of the budding White International Motors in Santa Ana, Calif.
SOME FORTY YEARS AGO, the HarleyDavidson motorcycle company began a program of racing development on a 45 cubic inch, side-valve V-twin with 2.75" bore and 3.81" stroke. And what are they doing today? You guessed it, gang: they are still working on that 2.75 x 3.81-inch, side-valve V-twin.
Rider Larry Mane easily outpressured competitors in TT races. Machine's performance led to drag record attempt. THE SUZUKI TRAIL 80 shown on this page has, with three quick changes of make-up, routed competing machines up to two times larger in displacement.
CZECHOSLOVAKIAN motorcycles - Jawa and even CZ - are famous on the roads of the world, and immediately identified by any fan as prime two-strokes. It is always a slight surprise to discover that both firms have been running four-stroke road racers in Czech and international competition for several seasons.
As WAS FULLY EXPECTED, HarleyDavidson's 50% displacement advantage took them over the top at the Daytona 200-mile national road race, and to the surprise of many, 1964 Grand National Champion Roger Reiman lived up to his numerical designation by thoroughly demolishing all opposition from the start.
THE CHANCE to own the motorcycle of my dreams came last summer when my wife Pat and I planned a trip to Europe. "This," I said, "is the golden opportunity to get that BMW. And we can also check the authenticity of that book which says one can travel in Europe on five dollars a day.
FEW NEW ENTRIES to the American market will be burdened with a more unattractive name than the Binetta Super 5. But, as Shakespeare said, what's in a name? In the name Binetta, seekers of lightweight performance and mechanical excellence will find a great deal to please them.
THERE WAS THIS OLD MATCHLESS 250 frame and a Honda engine lying in a friend's garage (such things are dreams made of). Along came Jim Kayser, a Granada Hills fireman and long time dirt churner, who was looking to build a machine suitable for the constant excess of California desert and enduro riding.
THE ENGINE is a 61 cubic inch F-head design with mechanical intakes and valves of unusually large diameter. Despite the large valves, breathing was restricted by the design of the intake cages. Possibly the most interesting feature of Merkel twin engines was the liberal use of ball-bearings throughout, with the main, big-end, and entire timing side gear train running on precision ball bearings.

THE SECOND European ice racing championships were staged in the Soviet Union, the same as last year. The fivestage competition was conducted in Leningrad, Moscow and Ufa. The cyclists of West Germany, Austria, East Germany, Yugoslavia, Bulgaria and Czechoslovakia vied with each other in the elimination rounds for the right to enter the finals.

TEACHING A GIRL to cowtrail may prove to be easier than the first job of teaching her to ride. Since she already knows the fundamentals of riding, learning cowtrailing may take longer, but it will be less complicated mechanically at the start.
CAROL SIMS The F.I.M. International races held at Sebring, Florida were certainly an improvement over last year's version. The American Association of Motorcycle Road Racers (AAMRR) organized the events over the 2.2-mile course instead of using the full 5-mile one.
AMONG THE MANY businesses in the motorcycle industry, the Joseph Buegeleisen Company, better known as Buco, rates special attention this month. Until a few years ago, Buco was one of the better known accessory makers, producing an extensive line of high quality windshields, mirrors and saddle bags, aimed at the midwestern heavyweight rider.
THE ITALIAN RACING SEASON was traditionally opened on a festive day in Italy by the Senior Championship event -with international "status" - on the winding Modena autodrome. And also traditional were a very dull sky, wet track and bitter cold, but fortunately the rain remained in the clouds.
THE 1965 SEASON is in full swing, of that there can be no doubt, for the United States Grand Prix opened the classic road racing season and world championship rounds of both 250 and 500cc moto-cross have been decided. Hailwood has been beaten on the big MV; a Russian has won a 250 moto-cross round; Sten Lundin, featured in color last month, won the first 500cc meeting; surprises continue on the British short circuits, and Sammy Miller really hit form with the Bultaco trials machine.
WHAT SIZE motorcycle do you ride? And what would you like for your next machine? Japanese makers can probably provide it among the 83 models and no less than 19 different piston displacement sizes currently on the market. It is practically impossible to count the total number of models made by Japan's manufacturers, as there are many which are basically the same machine with only the addition of an electric starter or dual seat or automatic fuel mixing device, etc. But, as counted by your reporter, the seven makers are now producing 83 basic models (not counting the variations).
