For the last threeyears, 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.
Which, ofcourse, seems
like an unfair advantage. Until
you consider this:
In 1984, Rick Johnson won
the250cc title aboarda stockYZ.
In 1985, Brae Glover won
the 500cc class aboard a stock

Translation: more horsepower.
There is,however, more to
building a high-horsepower
