Motocross, a sport rooted in innovation, has continually pushed the boundaries of engine technology. The transition between two-stroke and four-stroke dominance has been a hallmark of its evolution, and now, the emergence of electric bikes heralds a new era of racing.
In the early days, two-strokes were the undisputed champions. They were featherweight rockets with a crazy power-to-weight ratio that ripped around the track. But in 1997, Yamaha threw a wrench into things with the YZM400F. This four-stroke machine was a game-changer.
Yamaha's Doug Henry hopped on the YZM400F and blasted his way to victory in the final round of the '97 AMA Supercross season. It was a shocker that sent shockwaves through the sport. Suddenly, four-strokes weren't just contenders, they were winners.
Yamaha kept the momentum going with production models like the YZ400F. These bikes were smoother, handled like a dream, and never missed a beat. Four-strokes quickly became the go-to machines, leaving two-strokes in the dust.
