IT IS WITH GREAT pleasure, some pride and a touch of trepidation that I make the following announcement: Cycle World Magazine will send a team of American riders to compete for the team prize in the Isle of Man Tourist Trophy races. I have long thought that a team of the kind we are sending would be good for the sport, as it would help to establish a link between America and International motorcycling.
CONSIDERING SOME of the horsepower claims being tossed about these days, it might be a good thing to say a few words about this subject. James Watt, an engineer and inventor (circa 1800), devised the horsepower rating system we use, arbitrarily establishing one horsepower as 33,000 foot-pounds/minute.
Due to the tremendous volume of Service Dept. mail, we are unable to reply to individual letters. We shall continue to answer as many as space permits in this column. After boring a cylinder, do you consider it necessary always to hone the cylinder?
Just a few words of gripe and praise, and some questions. First the praise: You have got a great magazine, I mean totally one of the best publications on the market today. You exercise good taste in advertising, and your views on the many facets of our sport are as free from prejudice as they can be.
BEING A COMPLETE GUIDE TO THE SELECTION OF THE MOST PROPER, ATTRACTIVE, AND PRACTICAL CLOTHING FOR EVERY KIND OF RIDING.
ON THE FOLLOWING pages we present the most complete guide ever assembled to motorcycle riding clothing especially designed for both male and female riders. From items just barely recognizable as real cycle clothing, to the most specialized forms of competition wear, we have assembled samples from every maker among CYCLE WORLD's advertisers, and a number of others not represented previously, but seriously intent on dressing the motorcycle rider appropriately.
HUSQVARNA (PRONOUNCED OOSK-VARNA) is a name that has been associated with racing motorcycles for more years than most of us can remember. The company was founded around the year 1700 to produce firearms, and to this day Husqvarna is noted for manufacturing some of the world's finest rifles.
HONDA OF MICHIANA converted a Honda 160 for scrambling and built a near-custom bike in the process. A Super-90 front end, plus a Bates racing seat, ASC TT-pattern exhaust pipes, and Bates folding footpegs were among the visible alterations.
CYCLE WORLD last tested the 500cc Marusho in December 1964, and although we liked the machine, for various reasons at a factory level it never appeared in any great number in this country. Recently, an excited importer called us to offer a "completely redesigned, totally new Marusho" for testing.
Road Test and Technical Review, to be finished on the Daytona oval. ON OCTOBER 21, 1965, George Roeder climbed into a streamlined Harley-Davidson "Sprint" and zapped back and forth across the Bonneville Salt Flats for a two-way average, over the flying mile, of 176.817 mph.
GEORGE PUT NEW TIRES on front and rear. My rear tire was only a month old, so I put a new one on the front only. We waterproofed the tent the day before and left it pitched in the backyard to dry. My heavy-duty, thermal underwear had just arrived by mail that week, and George was to pick his up on our way through Oakland.
FRIEDEL MUNCH of Friedberg, West Germany, working in deep secrecy, has launched a very special project that has produced the first new big German motorcycle since the 1933 Tornax Silver Arrow. Münch's monster is powered by an NSU Prinz automobile engine, a l000cc (61 cubic inch) four-cylinder, overhead camshaft (driven by duplex chains), with fantastic torque and power options to suit customers, ranging from 43 DIN horsepower at 5,250 rpm, to 53 DIN hp @ 5,600 rpm, and 55 DIN hp @ 5.8,00.
A CUSTOM MOTORCYCLE IS A WORK OF ART. . . SOMETIMES
WHERE I LIVE in Greenwich Village, every spring they have this outdoor art festival. It's a big deal with the tourists. Exhibits are lined up on the sidewalks and a judging committee awards cash prizes. Every artist in the village (that is to say, practically the whole population) works all winter perfecting something to show in the festival.
FOR YEARS motorcycle racing in the United States has been confined for the most part to standard production machines, of the type generally available to the public. This is the core of the American Motorcycle Association's Class C rule, it has not been exactly inviolate.
Dick Hammer had it in the bag, but Mulder closed the string.
CONSISTENT WINNER at local AMA events, Eddie Mulder capped an impressive winning streak at the 6th running of the Ascot Park 100 lap TT (formerly called the Jimmy Phillips Memorial). Dick Hammer appeared to be star of the day from the drop of the flag when he took the lead of the 33 man field.
IN THIS WORLD of many, many small motorcycles, considerable time may elapse before we are able to check back to a particular machine. During the interval some of them change and some stay right where they were. The subject of this month's impression has not changed a great deal; outwardly the Suzuki 80 is a very familiar sight.
Motorcycling's fastest growing competition form, has an outing.
IT'S THE FINAL results that count. So it was with the second annual all-motorcycle drags at the Lions Drag Strip in Long Beach, California. The famed Southern California quarter-mile paved strip was playing host to over one thousand two-wheel speed enthusiasts.
IT is MIDNIGHT and lashing down with rain. It is also very dark and cold. Such nights were meant for snug warm beds, but instead you are riding a scooter up a black mountain road as fast as it will bore through the downpour. Your spotlight glistens on the wet tarmac, homing on the guiding white center ribbon.
AMERICAN HONDA has strongly encouraged their dealers to teach safety in every possible way, especially to newcomers to our sport, since the company was formed. This is certainly the proper way to sell motorcycles, if a new rider can get through the first month safely, there is a good chance he will remain a motorcyclist.
HANS JOHANSSON from Sweden was not happy with the normal selection of touring machines available, so he set out to build something better. The results are a 500cc Manx Norton single-cylinder, overhead cam engine, in a Norton "Feather-bed" frame.

THE SUGGESTION a couple of months ago that Arthur Dovey and Paul England would be good bets in Sammy Miller's Bultaco trials team has now been stymied to Paul's advantage. He has been loaned a works Cub by the Triumph factory to see how he gets on with it.

CYLINDER TEMP GAUGE
Bystrom Instrument Service, 6115 N. Ravenswood Ave., Dept. CW, Chicago 26, Illinois, tells us their new cylinder head temperature gauge is just the thing for motorcycles. The meter was developed for missiles and rockets where vibration is a serious problem, and they tell us they have modified it to use on twoor four-cycle engines. Actually, it matters not what type of engine it is, the gauge will give you the temperature regardless. An accuracy of plus or minus 1% is assured, and a steady needle under all conditions is normal. A brochure will be mailed to inquirers.

SUZUKI'S hot new 250cc has really shaken up the rest of the industry in Japan, and everybody seems to be jumping on the research and testing trail to try to come up with something to match it. The 29 hp, 100 mph and 15.1 second standing start quarter-mile claimed for Suzuki's Super Sport 250 model T20 (X-6 Hustler in the U.S.) is quite a high mark to aim for.
THE FIRST Swedish moto-cross events were held in the "twenties," but it wasn't until 1946 that the sport really began in earnest. After the war, motorcycle clubs were looking for new events in which to compete, and the British-type "scrambles" races seemed to fill the bill.
