YAMAHA AT DAYTONA - 1967 OILZUM 850 W ldIester Are., ••• '1lIewO., C.If" When 167 expert motorcycle riders representing a dozen major brands from all over the world compete in the biggest, most ill\Portant race in the country, the chance of one brand capturing 8 out of 10 positions is very slight. The mathematical odds of the same brand duplicating this feat two years in a row are fantastic. Yet one brand- Yamaha-did this very thing. At Daytona Beach, Florida. March 1965, in the American Motorcycle Association's 100 mile National Championship Race for machines in the 250cc class, Yamahas took 1-2-34-'7-8+10 with Dick Mann of Crockett, California, coming home the wiMer. On March 19, 1966. Yamaha set an almost identical record of 1-2-3-4-6-8+10 with first-year expert rider Robert Winters, of Fort Smith, Ark a n sa s, taking the checkered flag first. Veteran observers described Ibis classic event as "the best motorcycle race ever held!" The lead changed bands 42 times in 27 laps. Wben it was aI I over, tbe winner was oniy 12 lengths in front of second place John Buckner who led number three man Ralpb Whi Ie by a mere nose! Aller While came Don Vesco, fourth, DoD Twigg, sixth, Gary NixOD, eighth, SOnny Gager, ninth, and Larry Schaefer, tenth - all OD Yamahas. Because of these fantastic, unprecedented victories -at Daytona in the last 2 years, Yamaha, the second-fastest selling motorcycle in the United states, will he the brand that all motorcycle racing buffs will be watching at the 100 mile National championship race at Daytona Beach, Florida, next March 17-18. Just a few short years ago, Yamaha was playlng tbe part of the underdog at the country's top racing plants. Company officials decided that what they needed was a lightweight machine with lots of borsepower, superb handling qualities, aDd effective, reliable, brakiDg. To fill these requirements, they developed the DOW-famous TD-IA, an improved version of the TD-l, followed, and last year, still a beUer machine was built, the TDI-B. These machines, whicb sell for about $1,100.00 were patterned after Yamaha's "factory works" machines, the RD-56s, which won the World Grand Prix ChaQllODship In 1964 and again in 1965, with Englishman Phil Read as the rider. This year, Yamaha's Research Department has gone all out to perfect a brand new, YDS-5 road racing machine wi th a newly incorporated, AMA ap- I'_ Ron Grant, #1 AFII rllt.

With Yamaha riders Mike Duff, Bob Winters, Gary Nixon. and Tony Murphy mounted on these powerful bikes, another Yamaha "runaway" is entirely possible. Yamaha figures to be the brand to beat. at lhough several other brands have improved their productioD raclng models and the competition should be IllUcb tougher. Yamaha management people are most enthusiastic in their support of racing, because like most m~or automobile manufacturers today, they believe very stroDgly that Ibis is the best "researcb lab'" possible.
