Back in July 1994, Roger DeCoster, who was in charge of Dirt Bike Magazine’s testing department, had the opportunity to test the 1979 Yamaha OW40, which was the bike that Bob Hannah raced. This bike, owned by Terry Good of the International MX Museum, is considered one of the greatest works Yamahas of its time. In the July 1994 issue of Dirt Bike, Roger shared his experience riding the bike.
In his interview, Roger expressed his interest in understanding the competition during the late ’70s and how Yamaha’s works rear suspension was superior to the Suzukis and Honda bikes he had previously ridden. He believed that the Yamahas had an overall advantage, especially in the 500 class.
After 15 years, Roger finally had the chance to ride the OW40. Despite the muddy conditions at RedBud in Michigan, he described the bike’s rear suspension as forgiving and better than some modern bikes. He noted that the bike had a sharp midrange hit that was challenging to control, but when on the powerband, it accelerated as hard as a modern 250 MXer. However, he felt that the handling of the bike felt old, with the front end having too much rake and the handlebar placed too far rearward.
Contrary to his expectations, Roger found the fork to be soft, which he attributed to the rider position being farther to the rear. He concluded that the bike, while very good, would not be competitive in today’s motocross. He also acknowledged that the bike’s success was not just due to its excellence but also Bob Hannah’s exceptional riding skills.
1981 SUZUKI RM125
During his exploration of Dirt Bike Magazine’s archives, the author came across a photo of the 1981 Suzuki RM125, a production bike that significantly influenced the 125 two-stroke class. The RM125 revolutionized the class and set the standard for the next 30 years.
Prior to the RM125, the 125 class and motocross in general were evolving rapidly. Honda, Yamaha, Suzuki, and Kawasaki were introducing new advancements each year. However, the 1981 Suzuki RM125 stood out with its liquid-cooling system, vertically mounted rear shock, and performance in local and professional motocross competitions. The RM125 outperformed its competitors and paved the way for future advancements in two-stroke technology.
Although Suzuki’s dominance in the 125 class was short-lived, the impact of the RM125 was significant. It influenced the development of power valve technology and rear suspension design. Despite being surpassed by newer motocross technology, the RM125’s contribution in shaping the future of motocross cannot be undermined.
