It's all four won, and wins four all! Dr. D chalks up his
fourth World 4-Stroke Championship at Glen Helen, setting
the stage for a thumpin' weekend that saw three other
Yamaha-mounted riders take the checkers. Proving, yet
again, that there's only one brand of bike to be on when it
comes to leading 4-stroke performance.
