YAMAHA HAS proven itself for some time to be a farsighted, progressive organization, deserving of a great deal more credit than they receive. An example of the kind of worthwhile promotions that come out of Yamaha is their newly released Common Sense Tips for Safe Sportcycling book.
Mr. Mike Hailwood c/o Cycle World Books Long Beach 12, Calif. 90812 Dear Sir: My name is Paul Ertel. I am in the 4th Grade in La Cañada, California. We are studying about different kinds of Breakfasts. Would you please tell me what you usually eat for Breakfast?
JOHN DUNN I was wondering if you could run an article on some of the main technical terms you use in your road tests. There must be a large body of readers who have no idea what a solenoid is or what it can do in a motorcycle (or car), and not everyone I know has a very helpful understanding of an alternator and how it differs from a generator.
WHEN riders get together there is apt to be much bantering, especially with people like Gary Nixon, Dick Hammer, Bobby Winters, Neil Keen, Tony Murphy, etc. At Daytona on the Sunday before practice week, Mike Duff and a group of us were sitting around, relaxing and (what else) discussing racing.
HAVING NICELY SEWED UP the small bike market, the inventive Japanese have set about to dabble with the passions of the big-bore road rider. Thus arrives the second 350cc Japanese rotary valve two-stroke in as many months - the Kawasaki Avenger.
ON APPEARANCES, THE BULTACO PURSANG would seem to be a trend setter in some areas, while executing retrograde maneuvers in others. Design of the fiberglass components is, at first, startling and has one wondering whether the packaging people might have been given too much head.
WE REFER TO DAYTONA as our "classic." What is a classic, really? Is it a European Grand Prix with a hundred entries total and four or five factories represented? At this year's Daytona, the 26th running of the race, there were almost 750 entries and, just to prove that the factories are interested in America's most prestigious event, no less than nine manufacturers prepared special equipment.
Or, How Two Wheels Made Our Mighty Hunter Even Mightier...
ALFRED H. MILLER
SWINGING WIDE around the half-buried jeep and its sweating crew, I eased farther back in the saddle, gripped the tank firmly with my knees and cranked the throttle open. The Sprint, rear wheel spinning madly, bucked through the soft sand, churned up over the edge of the bank and then began the long climb up the steep, eroded slope.
RACING IN THE AMA large displacement class had gradually dwindled in participation to three brands, but this year a most refreshing shot in the arm came in the form of three orange and white screaming Hondas, entered by Bob Hansen of Racine, Wisconsin.
FEW MANUFACTURERS of any product are quicker to overcome a shortcoming, or to cash in on a need, than Honda Motor Co. It's difficult enough, we imagine, to be the largest in the world, but it must be an ever-present strain to stay there. Honda continually demonstrates the ability to adapt to the demands of the buyer, and, in most cases, hits the nail on the head.
THE TRIUMPH FACTORY stopped taking an active interest in racing almost 18 years ago when the Triumph Grand Prix project came to an end. But American tuners, being what they are, saw an engine that lent itself to home tuning; one that could be very competitiye under AMA rules.
"SUCCESS is one percent inspiration and 99 percent perspiration." So says a book marker sent by Al Stuckey, Pat Owens and Jack Wilson of Johnson Motors to the occupant of a first floor office at the Triumph works in Meriden, Conventry. It is not a big room.
FROM IDEA TO DAYTONA in 90 days sums up Yamaha's effort for the 200 miter. The three-month interval included design time, construction and testing; an almost incredible feat, considering Mike Duff qualified 8th fastest among the big bikes and, except for a broken gas tank, the two machines had 100 percent reliability.
IF YOU PLAN TO USE the bike you have, the problem of selecting a machine for' touring is already solved. But for those who plan to buy a machine, or trade in the old one, the following points might be worth considering. A little thought beforehand assures greater satisfaction later.
MAKING UP A PROTAR model from the well known kits marketed by ex-world champion Tarquinio Provini should be given just as much care as tuning a machine for the road. Then you will have a model to be proud of, for they are made with perfection in mind.
For some months we have talked about and anticipated the arrival of a brand-spanking new road racing chassis from the brothers Rickman. And now, after all manner of delays we have the unusual bird in hand - sans engine. In the meantime, while we decide upon and negotiate for a power plant, we offer an illustrated preview of what promises to be a very interesting test report.
THE WORLD OF CUSTOMS, particularly when applied to motorcycling, takes many a curious turn. But there is none more attractive, perhaps, than this showdragster created by Detroiters Gerald "Ace" Novak and Maynard Rupp. "Hand Grenade" has won three "best bike" awards in its first three exhibition outings.
THE BENELLI "FOUR," which Renzo Pasolini rode to a winning debut at Modena and set the fastest lap of the day two weeks after at Riccione (finishing second to Agostini in spite of brake fade), is a full size 498cc job. It was built in a few weeks, shortly before the opening of the 1967 season.
I have been reading your magazine for quite some time now and have been interested in the letters from people about the laws which are being passed governing motorcycle riders. There has been a lot of talk in our state about doing something about the two-wheeled vehicles on the high ways too, and I am beginning to wonder how much longer we are going to be able to enjoy riding our motorcycles before a group of laws is passed which will make it so complicated that it won't be a pleasure anymore.
ONTARIO IS THE FIRST province in Canada to enact special legislation concerning the licensing of motorcyclists. The new law went into effect Jan. 1. Other Canadian provinces are expected to follow suit. As of this year, Ontario requires separate tests - written, visual acuity, and practical - to qualify for a motorcycle rider's license.

IF YOU LIKE traction unlimited, lots of competitors, and the chance to see what you look like on TV, you should have been among the 218 sportsman riders who scrambled at Salinas, California. One of the best organized clubs going, the Salinas Ramblers ushered riders and spectators into separate, chalk-lined parking areas with a brigade of arm-waving, finger-pointing specialists.
Pardon us if we digress from racing for a moment, but we took a weekend trip to the northern part of California recently to do a spot of trailing. Trucking north across the Golden Gate Bridge we arrived in the hilly tree-studded country at the north end of San Francisco Bay to stand in front of a 2,000-acre plot of virgin ground.
FRITZ SCHEIDEGGER DEAD at Mallory? It was a shock. I had strolled to the office after the Easter holidays to be shown telex-reports mentioning the death of the FIM world champion sidecar racer. Scheidegger, a friend. The man who had never had a serious crash died on the track on Easter Sunday when his outfit went out of control in the high-speed approach to the Mallory hairpin.
WITH PUBLIC HOLIDAYS On the Friday before and the Monday following Easter Sunday, the weekend is an absolute festival of sport, especially for the road race fans. But tragedy struck at the International Sidecar Race of the Year meeting on the Sunday at Mallory Park: in the big race Fritz Scheidegger and John Robinson, the world champions, crashed at the hairpin.
JAPAN'S MOTORCYCLE MANUFACTURERS are looking more and more to large size machines as popularity and sales of the smaller bikes continue to level off. Both Kawasaki and Lilac (Marusho) always had big four-strokes in their line, the current being a 650cc parallel twin and a 500cc opposed twin, respectively.
THE ITALIAN ROAD RACE season opened as usual on March 19th with the international Modena meeting held over the twisting 3.8 km autodrome with fine weather and an attendance of 25,000. In the 125 race Walter Villa led comfortably from start to finish on a singlecylinder rotary valve Mondial.
THE EXOTIC theories and formulae applied to the design of two-cycle engine exhaust systems are enough to baffle most of us. For the first time to our knowledge, someone has put together a useful handbook for designing and building these engineering marvels, that even the simplest mechanical minds can grasp.
