CALIFORNIA TRADITIONALLY has always been sort of the Valhalla for motorcycles. The climate is nearly ideal, and riders, dealers and distributors have always enjoyed an atmosphere that was friendly and receptive to motorcycles for the most part.
How complex will Grand Prix machinery become? These first “naked” photos of the Yamaha four reveal a plumber’s nightmare, but it seems that to obtain 150 mph (requiring about 60 bhp) from a 250cc two-stroke, this is the way one must go about it.
In regard to your answer in the Service Department, September 1966, about STP in a Honda Super Hawk. I made the mistake of adding STP to my Super Hawk about two years ago. STP seems to have an unfortunate property of swelling cork. I had to buy a new clutch about one month after aforesaid operation.
I am enclosing the photo of my NSU “Max,” which is specially built with one thing in mind and that is to go to the motorcycle races, some of which are 180 miles away from home. “Max” is quite a potent lightweight machine with top speed of 102/105 mph (depending on sprockets used).
WITH ONLY ONE MORE round to go in each class, both the 250cc and 500cc World Motocross championships were won, and when the 500 series had its last round in West Germany, only fourth place was changed. In the 250cc class, Sweden’s Torsten Hallman has confounded the experts by winning his third 250 title on the Husqvarna after having been absent from the Circus for two years.
ONE CANNOT APPLY the same set of standards to a competition machine that one applies to a street scrambler. In some areas, one is tougher. In other areas, one may be more forgiving. Thus, to clear up any misunderstanding, it should be known at the outset that the Matchless G85CS 500cc single is “strictly for serious.” Otherwise, at $1,400, it would have to be considered the most expensive play bike in production .
IT requires an army of men to properly pull off an event like the International Six Days Trial — and this is precisely what was used to stage the 41st of the old man of endurance trials. The Swedish army financed, planned, controlled and timed the entire event with superhuman efficiency and totally military demeanor.
BONNEVILLE '66 will be a memorable week in motorcycling for several reasons. Stacked up against the ’65 running with its disappointing “bad salt,” it has given the speed merchants welcome encouragement in the form of 15 new records and 15 broken old ones.
THE OUTSTANDING 1-2-3 Bultaco victory in the 250cc class of the 1966 Ulster Grand Prix will go down in motorcycle racing history as one of the most decisive wins by a small factory. Even more startling than the 250 victory, was Tommy Robb’s ride to third place in the 350 race, behind Hailwood and Agostini.
ORIGINALLY SCHEDULED for the first two weeks in June, the Isle of Man TT races were postponed because of the British seamen’s strike. Through great efforts on the part of Isle of Man authorities and the A-CU, they were eventually held at the end of August.
THE VISUAL IMPRESSION one gets of the Garelli Rex is that of a Six-Days lightweight suited up for a Sunday ride through the park. Starting with its 19-inch wheels, moving up to its nicely fitted and finished alloy fenders, then to the high, wide bars, its ample, comfortable, sharply trimmed dual seat, and ending with the no-nonsense taillight-license bracket, the little Rex looks every bit of an endurance trials bred machine.
AN EMERGENCY can often bring out the best in people, and the delayed races did just that, inasmuch as it was necessary to hold the sidecar and 250cc races on a Sunday this year to enable riders to attend the usual Bank Holiday Monday meetings on the mainland.
AND YET ANOTHER new marque is added to the growing list of lightweights available in this country. The delightful little Cimatti (pronounced Chee-mot-tee) bear no great concern as road racers, but certainly merit consideration as small touring numbers.
EDDIE MULDER became the first rider to win all three national TT championships in one year as he “Triumphed” in the Peoria event and capped off a great season. It was the sixth national win for Triumph this season, which placed it far ahead of the rest of the brands in major event wins.
WITH ONE LAP to go, after leading the Springfield, Ill., 50-miler from the start, Mert Lawwill’s powerful Harley faltered, slowed drastically, and the complexion of what had seemed to be a runaway race changed completely. Victim of a burned piston, the leader nursed his ailing mount down the front straightaway as 30,000 fans moaned in sympathy, then turned their attentions to the snarling battle for second, 17 seconds behind.
THE FELLOW WHO COINED “When you want something done right do it yourself,” passed on to posterity a rule that many men live by and with which many have achieved unparalleled success in one field or another. But we know of one man who would surely take you to task on this advice.
IT STARTED a couple of weeks ago. I was taking a shortcut through the vacant lot known as the Frumpville City Park, on my way to pick up my unemployment check. A big day. Soon the fantastic sum of $36.44 would be thrust into my hot little hands. The thought of enough money to buy gas for the bike and perhaps even food for the table, boosted my spirits and I ran through the underbrush.
BINGO FOR BULTACO! With a 1-2-3 victory in the 250 class of the Ulster Grand Prix, it was the surprise result at this year’s meeting, run, as usual, in wet conditions on the 7-1/2-mile Dundrod circuit in Northern Ireland. Course alterations at the infamous Leathemstown Bridge section had changed three tricky corners to a fast straight and this accounted for 125 and 500cc lap records by Honda teamsters Ralph Bryans and Mike Hailwood, respectively.
BEFORE YOU RUN the 500-mile National Jack Pine Enduro, they give you a cow bell. Some riders leaving the start at Lansing, Mich., wished they had brought theirs in tow, so they could ring for help before they sank to their ears in mud. At 5:30 a.m. on a damp, overcast Sunday morning, the first of 576 riders left Lansing.
THE LITTLE FINNISH TOWN of Imatra, near the Russian border, goes “continental” once a year when the Scandinavian round of the world road racing championship takes place. The Fifth Finnish Grand Prix, held for the third consecutive year in the Imatra area on the well-known 6,030-meter-long public road circuit, was a great success.
ONCE A YEAR all the champions climb aboard the lightweight 250cc machines to do battle in the annual national short track championship at Santa Fe Speedway, located just south of Chicago. Santa Fe runs weekly short track events on its fast quarter mile from May until early September and produces the majority of the nation’s top small bike oval artists.
IF YOU’RE REALLY LOOKING for an argument, get together with a couple of the guys around a pitcher of beer and see if you can come up with a good-in-every-case definition of a motor scooter. That may give you a rough idea of the job facing Lieutenant Walter Stecko and the eleven troopers who make up the brand new Connecticut State Police Motorcycle Task Force.
In the turbulent world of motorcycle drag racing, it's hard to say who holds what record during any given week. It changes too fast. One thing for sure: the bikes are catching up with those funny cars and rail jobs when it comes to putting on fantastic, frightening shows of smoking speed.
Bates Industries, Inc., the racing seat people, have engineered a new line of plexiglas fairing-shields, which are contoured to control flow of air around the rider and cut wind resistance.

The rear shocks come in three models: non adjustable, five-way light duty and five-way heavy duty. Front forks are available for the following machines: Montesa 250cc scrambler, Ossa 230cc scrambler, Bultaco 360cc scrambler and the Ossa 175cc road racer.

BRACE FOR LIGHTWEIGHTS
The front fender on your motorcycle not only shields you from dirt, it also serves structurally, keeping the fork tubes in alignment, and tracking together vertically. Thus, if you remove the fender or if its braces are flimsily built, the bike will behave badly in the rough. This example of a heavy-duty U-brace for dirt machines is made by Circle Industries. It fits a large number of small tubular fork motorcycles: Honda S-90, 160; Hodaka Ace 90; Yamaha 65 to 125cc; and others. It will fit over a 4.00 tire. The brace is made of polished aluminum and costs $6.95. Write Circle at 9914 & 3/4 E. Rush St., Dept. CW, S. E1 Monte, Calif.

REAR WHEEL DYNO
The Stuska Engineering Co. has recently finished development work on a dynamometer for motorcycles and plans to start production soon. Brake horsepower figures are taken by removing the rear wheel of the machine and mounting it on the stand. The only accessories needed are a strong fan for engine cooling and a garden hose to feed the water brake. For further details, write Stuska Engineering, Dept. CW, 1215 Speer Blvd., Den-ver, Colo.
HAVING MADE due comment last month about the need for sponsors (if Americans are to have a really good go at road racing over here), let me start this month by paying tribute to A1 Fergoda, of San Francisco, who has provided the Yamaha, together with spare engine and parts, for Bill Boyd to race this season.
LAVERDA, a medium-sized factory in Breganze, North Italy, is part of a huge industrial plant producing agricultural machinery. It began producing motorcycles soon after World War II and since then has become well-known for the original features and good quality it incorporates in the machines it makes.
MORE JAPANESE motorcycles were exported to war-torn Viet Nam in August than to the United States, Japan’s best customer. The cause was a big sale of 22,000 Honda 50cc machines to the Viet Nam government. They were handed over to Premier Nguyen Cao Ky at a ceremony only one month after the order was given.
