SINCE STARTING NEXT MONTH, with OUT July issue, we will inaugurate a Classified advertising section, I thought maybe the following item might make a suitably interesting way to begin things. It was sent to me from Yamaha International; If the man who “borrowed” the Yamaha racing engine from our service van when it was parked in Daytona will contact me, perhaps a new and flourishing team can be born.
“Torque peak” is the point in the rpm range at which maximum torque is achieved. This is controlled mainly by valve timing characteristics, and at this speed, maximum volumetric efficiency (breathing capacity) occurs. The torque curve will drop, mainly in direct relation to the volumetric efficiency being obtained.
TECHNICALLY SPEAKING, the most significant overall factor at the 1966 Daytona road races was the unprecedented “factory” participation. Virtually all of the major names in motorcycling, with the notable and regrettable exception of Honda, had put together strong team efforts for this event.
Mr. Craven’s article was interesting, but I can’t say more for it. I have spent many months preparing for the day this summer when I take delivery of my new BMW in Munich and set off gallantly over Europe. But I have had to dig out necessary facts for the journey from many places and sources and so many of these important facts were omitted from Mr. Craven’s article.
DAYTONA’S big 3.81 mile “long course” has been a Harley-Davidson stamping ground since its inception in 1963, and during this year’s practice and time trials there did not appear to be any reason to suspect a change in the winning brand. Thundering along the high-banked tri-oval, the big Milwaukee Vee-twins looked invincible, but a smiling, soft spoken and extremely smooth-riding Texan named Buddy Elmore and his Triumph, purred along almost unnoticed, to beat them at what has been their own game.
BSA’S SPITFIRE MK II is the offspring of a welldefined trend that is seen both here and in its native England. More and more, motorcyclists are turning from what might be described as “basic transportation” in a 2-wheeler, and toward the high-performance, sporting models.
ONE OF THE BIGGEST PROBLEMS facing the new motorcyclist, or the fellow who wants to graduate from the motorbike stage, is selecting a machine that will give him the most pleasure for dollars spent. Also faced with this problem is the large group of motorcyclists who want a bike for part-time transportation on the street or highway; yet suited to riding off into the country or across the desert in search of trails.
THE 1966 EUROPEAN MOTO CROSS SEASON has started. Every year the first big event is the International 500 race held at St. Anthonis in Holland. Usually it is cold and wet but this year that strange ball of fire hung in a clear blue sky all day. Everyone was amazed but it had a good effect on the riders for there was first class racing and the Dutchmen flocked to the circuit in droves.
IN EUROPE, scrambles races (known there as “Motocross”) have an enormous popular following, and therefore, quite naturally attract the absolute best in riders and equipment. There is room for argument with regard to anyone’s choice of the “Best Rider,” but indisputably, the best motorcycle in the 250cc class is the little-known (in America) Czechoslovakian CZ. The CZ won the 250-class World’s Championship for Russia’s Victor Arbekov in 1965, and for Joel Robert, the Belgian phenomenon, in 1964.
WILLIAM TARR is a Triumph riding, serious and dedicated sculptor whose more conventional work can be found decorating many attractive structures in the Eastern United States. The creations on this page are serious works of art, the results of a great deal of time and creative effort.
IN ANY FIELD of manufacturing enterprise the economic factors involved are always a major force which a company must recognize. If a company ignores or miscalculates the economics of their market, they soon may go broke. Conversely, a proper appraisal of the market can get a ready acceptance of a company’s product, and the future of the business is established.
THE SIGHT OF TWO TRIUMPH ENGINES coupled in a single frame is nothing new. You see it on the drag strips repeatedly. But just look at this Norton-Triumph; the crankcases are welded together! Sorry you can't see this monster in action, but right now it's in the window of Bob Foster's emporium in Parkstone, Dorset, England.
IT WAS JUST BEFORE DAWN in a drizzling autumn rain wjen my wife and I pulled out ot our driveway in Miami, 1-~1orK1a, and headed our new Honda 300 for Mexi co City. I had traded my criminal law practice for three weeks in Levis and boots, but didn't realize then what kind of trade it would turn out to be.
DESPITE THE FACT that only one engine (the works BMW) has more than a three-wheeled ghost of a chance at wining the FIM world sidecar championship each year, European three-wheeler racing continues to attract a huge following, season after season.
SPAIN CONTINÚES TO LOOM large on the motorcycle horizon. Montesa, Bultaco, Ossa, and now the Derbi, are the reasons. Derbi has made a deep impression in International grand prix road racing in the 50cc class, beating even the mighty Japanese and German machines.
EVERYONE WHO HAS been around the racing game has probably come up with an idea of what his “perfect” machine for the job would be. Young California banking executive Clay Jacobson (some will remember him better by the #9 he held a few years back in District 37 sportsman scrambles racing) had such an idea and, by virtue of his expertise, a wonderful bike to start with — a Matchless G-50 CSR, one of that batch of 50 imported to these shores before production stopped.
FOR CALIFORNIA RACERS, the opening half-mile event at Ascot Park each April is more of a New Year’s celebration than January first. Tuners have labored long and hard throughout the winter, preparing and improving their very special machines for this very special Friday night.
Dayton, Ohio, is the newest area to be hit by the moto-cross fever, a form of scrambles, European in style. Members of the Dayton Motorcycle Club grubbed, sawed and hacked a one-and-one-eighth-mile course which has everything; jumps, rights, lefts, sand, rocks, corduroy, two creek crossings and a straight-up hill.
More than a year of research and development has been put into one of the most stylish and practical sports shields for BMW we have ever seen. Using the best fiberglass products available, Evergreen Enterprizes has kept weight to a minimum without sacrificing strength, thus eliminating buffeting.
WE KNEW BEFORE THE SEASON STARTED that road racing in England was going to be close in 1966 on the short circuits, but if racing goes on as it has begun, then there will be a few shorter finger nails among sponsors and spectators before the end of the year.
Two huge Ponderosa Pines stood some thirty yards from the starting line, not swaying, but solid, immovable, unforgiving objects. Each tree had an arrow on it and each arrow pointed toward the narrow five foot gap that separated them. Shuddering at what I was afraid these arrows could mean, I turned to the large, leather-clad man standing next to me.
THE ITALIAN SEASON opened with the traditional Modena meeting on March 20th, thus enabling one to have a better picture of the various factories’ racing plans, which have been kept secret or semi-secret until now, and have caused many false or exaggerated stories to get around.
As a police officer and ardent motorcyclist, I watched with mixed emotions recently as a State College, Pennsylvania, patrolman ticketed a motorcycle rider for reckless driving. The cyclist, frustrated by a long line of traffic, had passed the string of cars by riding down the center line between lanes.
Russ PORECHA OF BOMBAY, went to Europe to represent India in the Olympics during the mid-1950s — racing bicycles. Later Russ was joined by his brother, Bob, and they decided to stay around Germany for awhile, working at NSU and Volkswagen, where they began to pursue their first love, motorcycles.
AT LEAST FOUR riders will come from the United States to participate in the MCFAJ 16th All Japan Moto-Cross this autumn. The New England Sports Committee has told the MCFAJ they will send a four-rider team mounted on 250cc Bultaco machines with perhaps a spare rider to boot.
