THE INDOMITABLE spirits of motorcycling live nowhere stronger than in a group I recently joined, where I rode my first motocross. One would think that at my age I would be content with an occasional enduro, cross-country trip to Baja, or a nice hard days riding at Saddleback...not so.
Hey, what happened to the reprint credit on those two sidecar articles in the April issue (Principles of Rigging, and Legality and the Hack)? Roger Hull, Editor Road Rider Magazine South Laguna, Calif. The Association of Trial Lawyers of America endorses the concept of a fair “no-fault” automobile insurance plan that protects the motorcyclist as well as the auto owner without inflicting additional cost.
I think Hodakas are great bikes. I’ve had a 90 for about six years and I haven’t had any major breakdowns until last summer. The coil apparently cooked and I sheared a couple of gears in the transmission, but after all those years of very hard use what can I expect?
Motorcycle racing had hit the big time again, but it just didn’t FEEL like it. The aura of something special was missing. Tickets were still available, according to the marquee, yet there were no lines of people waiting to buy them. The running of the race wasn’t up to big time standards, either.
This book isn’t intended to replace the workshop manual for a specific motorcycle, but study of it will make certain portions of a shop manual easier to understand. The book is filled with many good illustrations and graphs, most of which are explained in detail, which is helpful to the beginning motorcyclist.
THE MOST FUN thing I've been involved with during the past couple of years has been working on the radio broadcasts of select American Motorcycle Association National championship road races. Quite a change from the worries of anti-motorcycle legislation, helmet standards, and some of the tedious aspects of motorcycle safety, the broadcasts have presented a refreshing break.
NO, THIS isn’t a test of the most outlandish superbike ever invented...a twelve-cylinder behemoth with more power and bulk than sanity allows. Rather, it is an evaluation of Kawasaki’s total offering of performance oriented two-stroke Threes.
THE PRIME reason for a recent visit to the Husqvarna factory was to be present for a special motocross training camp, developed by the Swedish Gymnastics & Sports Training College in Stockholm. The camp began as an experiment in 1965. A team of physicians, headed by Dr. Bengt Saltin of the Swedish Physiological Institution, carefully measured the motocross rider’s bodily functions during and after motocross racing.
THE FIRST day was a bastard, there’s no other word for it. Not only was it hot, dry and very dusty, but the terrain was the rockiest I’d ever seen, and the schedule very tight. The “A” schedule had been opted for on the very first day, instead of the usual, easier “B” schedule.
ONE MAN'S meat is another man's poison, and in the currently raging controversy about noise, that seems to be right on. There is a story about two Cockneys in London—a city noted for the number and variety of its church bells. "Ain't them bells loverly?" asked 'Arry.
SOUND IS best described as a series of vibrations. These vibrations are changes in air pressure, and they can set off sympathetic movement in structures such as a wall panel—or parts of your ear. You can detect faulty bearings with your motor idling by placing the tip of a screwdriver on the castings, and holding the end of the handle against your ear.
ALONG WITH the wonderfulness of his mind and the nobleness of his soul, Big Brother is blessed with uncanny sensitiveness of his ears which, when perked by a passing twostroke, send neural signals to his Iron Fist, twitching and itching with eagerness, to squash errant bikers...and the manufacturers who supply them with loud exhaust systems.
Husky Offers The Ultimate Promise in An Off-Road Motorcycle . . . But Falls Short In Several Respects
AH, THE HUSKY. Ruler of the desert. The all-conquering enduro machine. J.N. Roberts and Malcolm Smith ride ’em, and there are many who feel that Husky is the bike to own once you’ve reached expert in off-road status. But how about the novice or newcomer?
A Swedish Concern That Deals In Precision, But In A Conservative Sort Of Way.
HUSQVARNA Vapenfabriks Aktiebolag, founded in 1689 as a government factory for the production of military weapons, has not made any guns for about five years. Now its main business is the manufacture of kitchen accessories, sewing machines, and a line of world championship winning motocross motorcycles.
IT IS probably safe to assume that in the early days of vehicular travel, engineers gave very little thought to operator or passenger comfort. So enormous were the problems of metalurgy, electrics and lubrication that just getting the device to run became a monumental task.
A good day for privateers... disaster for the Harley Team... Saarinen leads a 1-2-3 Yamaha sweep in front of a record crowd of 61,000.
JARNO SAARINEN (photo 1) didn’t think he could win the Daytona 200 miler. It isn’t that he lacks confidence. He has plenty of that. It’s just that he doesn’t consider Daytona a riders’ track. And, he may be right. There are really only three places riding ability pays dividends.
The Vehkonen Replica: A Proven Performer For The Motocross War
MONTESA’S MAIN emphasis the last few years has been centered around trials machines, and it’s success in this field is well-known. Recently, however, some of this emphasis has been shifted toward motocross competition, and the results have been gratifying, to say the least.
I’M SORRY, but we can’t serve you.” “Why not?” “You rode here on a motorcycle and you have leather jackets and helmets with you.” “Well, I’ll be damned!” On the way out of the restaurant, Joe resisted the temptation of bowling the penny gum ball machine over, or slamming his helmet into the mirror of the cigarette machine.
Practicality Usually Takes A Back Seat To Performance . . . But Not Always
THE Harley-Davidson/Aermacchi 125 Rapido model, first introduced into this country in 1968, made a lot of friends with the road riding commuter set. A 125 clearly isn’t the hot tip for freeway jaunts, but for around town use it’s a nicely sized machine.
THE 175CC YAMAHA desert racer featured here began life as a 125cc AT-2MX. The move to 175cc was straightforward because of the 100 to 175 displacement allowed in AMA's Division 2, the lightweight desert class. The larger displacement was attained by simply installing Yamaha's 175cc CT-2 cylinder and piston, which bolts effortlessly in place.
FREETHINKING Alfred Angus Scott, father of the water-cooled, two-cylinder, two-stroke, two-speed motorcycle that made his name a byword within and without his native Britain, shared Carcycle’s belief that “the English are a dumb people.”

Ducati has snapped up hard riding Mick Grant to ride its big 750cc V-Twin at the all important Imola meeting. The only snag is that the Italian concern has been held by strikes in Italy and the first machine will obviously go to home rider Bruno Spaggiari, who finished 2nd to Paul Smart last year.

ROMERO'S STOP What do you do if you're wailing down the backstretch at Daytona and your Triumph flat runs out of gas? If you're Gene Romero, you improvise. Romero took up coasting and got as far as the chicane...sighted in on an abandoned Yamaha...ripped off the gas tank...poured said contents into his Triumph...and motored away.
