Space Aged MX: Some of the Best and Worst
For years motorcycles were used for on and off road purposes but with little or no way in distinguishing their differences. Other than knobby tires for better traction they were the same as any on road motorcycle. The original on/off road motorcycle was produced in 1955 by Yamaha. The YA-1 had a 125cc 2 stroke motor that perform quite well but riders had to wait over a decade later for Yamaha to produce the DT1 in 1968. It wasn’t until 1973 when Honda produced the very first ever off road motorcycle platform. The Elsinore CR250M was a revolutionary “dirt bike” known as the bike that put Honda ahead of the industrial power curve. Dirt bikes produced in the 1970 and 1980’s were amongst the most influential in history and paved the way for recreational and competitive motocross as we know it today.
Numerous manufacturers tried building the ultimate dirt bike in the 1970's. Some were great ideas and others were disasters like the Suzuki TM400 Cyclone and the Yamaha SC500 Scrambler. Both bikes were well advertised and the ideas behind them were of high expectation. These two bike companies advertised the concept of only being able to win races with their bikes and on top of that new sticker price for one of them was an affordable $1000. Mated with extreme horsepower big bore motors, rugged suspension, knobby tires and a trophy waiting at the finish line these bikes should have been amazing but instead Suzuki and Yamaha were haunted by gremlins in their power plants. The TM400 had a finicky ignition system and the SC500 would spontaneously detonate. Both motors had a light switch throttle response. Either the power was all off or all on resulting in the front wheel lifting off the ground uncontrollably. On top of motor problems the suspension components for these two bikes provided only four inches of travel.
Dirt bikes produced in the 1970’s were not failure...
