Will the Daytona winner's circle be another Pig Farm (left) or can the Yamaha crew (above) get Kenny Roberts' 500cc square f our there? By Steve McLaughlin Steve M cLaug hlin won th e Daytona Su pe rbik e race in 1976 on a BMW an d in 1978 on a Yosh imura Suzuki. H e led th e Dayt ona 200 on a TZ 750 Yamaha in 1975, crashed wit h 15 lap s to go, and p ick ed up his bik e to finish 6th without a win dscreen. I n 1980 he uias m anager of the H onda racing team and rode a superbike for the team. Going back fa rther, the current Superbike rules started with M cl.aughlin 's suggestions, ditto with th e current Form u la One ru les. H e w as AMA rider representative fo r six years. H e's no longer racing , bu t he's pa id enough attention to want to stic k his neck ou t with th ese Daytona predictio ns. The 200-mile Formula One race T he Da ytona 200 is un ique in severa l ways. First is th e doIl ar s. It has th e biggest purse of a ny single race in the world and a lways ha s. And th e rid ers get th at m oney n ot thro ug h start m o ney- th ere is n 't a ny -but by wi nning, so the riders ge t w hat th ey' re worth. . It 's a lso a n event with the fas test mo torcycles in the world co mpe ting o n th e fastest track in th e world . Because of th e Formula One rul es wi th different displ acem ent capaci ties ( I025cc four-strok es, 750cc two-strokes with 23m m intake res trictors, unrestricted 500cc tw o-strokes) the race has interesting co n tras ts mech an ica Ily. The len gth, being 200 m iles, mak es th e race more di fficult. Grand Prix races ar e abou t 100 miles. The Da ytona 200 isn 't quit e long eno ug h to cha n ge tir es partwa y throu gh , so th e ti res ar en 't working very weIl th e la st 40 miles a nd neither is the chai n , genera Ily. There's a cert a in a m o u nt of wear a nd tear and fatigue and stra tegy going on. In th e 200 mile races I've been in -I think I've been in 12-the great est machine mortalit y ra te co mes about 40 m iles from the end. The setu p of the machine is uni que. You're run ning at a higher speed th an a t a ny ot he r m otorcycle tra ck in America. You h ave to set yo ur suspension u p a littl e stiffer for th e ban k turns a nd yo u try to work on your h yd ra u lics and your fork damping, so you don 't get extreme p itch ing when you' re o n the brakes. Yo u co me u p to a turn a t suc h a hi gh speed a n d j lim p o n th e brak es a nd you get a lo t of weight transfer and you have to keep the rear wheel on the ground. It 's basicaIly a horsepower/brake track. You naturallv have to have good brakes a nd have to get the suspe nsion rig h t so the thi ng is stable a nd ha ve yo u r tran sm ission ra tios righ t for acce lera tion and to p spee d, and yo u 've got to hav e pow er. Da le Singleto n ha s won the Da yton a 200 tw ice and finished secon d once a nd he's a perfect examp le o f the most successfu l stra tegy . AIl the guys I've seen win a t Daytona did th e sa me thing. Thei r primary effo rt isn 't to be th ere with th e leader s a t the drop of th e sta rti ng flag. T he successful stra tegy isn' t to be th e ha re but ra th er the hound. But yo u h ave to be close, not ou t of sig h t o f th e leaders, a t th e critica l last 20% of th e race. At the beginning Singleton a lways run s a bo ut si xth , seven th , eigh th, right aro u n d th er e. And h e's read y when th e o the r g uys h ave th eir probl em s. Th is yea r th e race wiIl have an un us ua Ily large num ber o f co mpe ti tive riders, so p it stops, getting in and o ut of th e pits and gettin g re fueled witho u t ca tch in g fire , is going to be very importa nt. Eve n pit signals co u ld m ak e the difference. You're looking a t th e best 200 field since 1974 when Ago stini won. Ra ndy Mamol a , Kenn y R o berts, Fr edd ie Spencer, America 's best , co up led with two-time winner Singleton and a very strong lineup from Europe, Fanta n , Sa rron , Va n Dulmen. Unfortu na tely, I u nderstand th at 500cc World Champion Marco Lucchinelli will no t co m pe te. T he n there's the co n flic t bet wee n machine typ es. T he top works four stro kes will hav e the most horsepow er. Next in th e power ba ttl e a re th e Yamaha TZ7 50s, bu t o n ly th e very to p runners in tha t g roup, like Singl eto n's . T he big four-strokes wi Il ha ve th e top speed, th e T Z750s w iIl h ave th e acce lera tion, a nd th e 500s will be very close j udging by the la p times turned by Law so n a nd Ma mo la in testing . T he fo ur strokes wiIl get the two stro kes coming off th e line bur the agility of handling and th e light weight of both the 750s and the 500s will even it out as the race goes on. I still think the Yamaha 750 is the best bet for win . We sti Il do n' t kn ow if the works 500s will last the dis ta nce.If'he Yam aha 750 has a proven track record.
