VINTAGE MOTO MONDAY: 1971 Yamaha DT1MX

Remember when Yamaha made a motocross version of its classic DT1 enduro?

Yamaha's immensely popular DT1, introduced in 1968, is another super significant machine because it was capable in the dirt. Although the original DT1 was a street-legal enduro with headlights and blinkers, many people took off that extra hardware and enjoyed their bikes on local trails. Two years later, in 1970, Yamaha did the same thing and created the DT1MX, stripping off the bike's lights and fitting the compact machine with the Genuine Yamaha Tuning kit as standard equipment. Fun fact: This particular example is a 1971 model, and Tom White says it has never seen the dirt. In fact, it has only been ridden down the alley near a Yamaha dealer in Chicago, Illinois. Neat detail: Automatic oil injection means there's no need to pre-mix the fuel. Yamaha's first serious MXer, the YZ250A, was still a few years off.
