For the last three years, factory motocross teams have been
divided into two distinct camps.
Thosethat race $100,000
one-of-a-kind works bikes.
And those that race $2,000
stock bikes.
VVlllch,ofcourse,seems
like an unfair advantage. Until
you consider this:
In 1984, Rick Johnson won
the250cc title aboard a stockYZ.
In 1985, Brae Gloverwon
the 500cc class aboard a stock
YZ. And, inbothyears, stock
YZ'swere responsiblefor more
than theirfair shareof supercross victories.

unfair advantage. And so did
the American Motorcycle Association. They stepped in and
changed the rules. Now everyone will have torace stock
bikes. Which eithermeans we're
three years ahead or they're
three years behind.
The samedifference as far
as you're concerned.
Of course, it would be a lot
easierfor themtocatch up if
we were standing still. But

There is, however, more to
building a high-horsepower
