Harley-Davidson vs Honda. Mechanics and bikes 1987 Springfield, IL Mile L to R: Bil Werner and Al Stangler worked on Parker's XR750. Mike Velasco, Skip Eakin and Ray Plumb worked on Bub Shobert's RS 750. The greatest riders need flawless equipment to battle for championships. One DNF could tip the scales to a point that could not be rectified in a season. Weight limits are a good example. How close could one come to the limit ? Shobert won an event at Syracuse, New York and was a pound and a half light- and was disqualified. That is how close.
