What do you associate Yamaha AT bikes with? It is the simplicity of a single cylinder dirt bike? The early days of learning how to ride a bike? Camping trips with family or helping on a farm? If you grew up in the 1960s or 1970s, this little gem could have easily played a massive part of your childhood.

Yamaha AT1 125

The pearl white Yamaha 125 AT1 was introduced to the market in 1969. It was designed for young beginner riders or for crowded city streets, where agility was a key.  The dual-purpose enduro AT1 was light, yet robust enough to be knocked about off-road, easy to maintain or modify and most importantly reliable. It was basically scaled down version of its larger sister the DT1.

Yamaha 125 AT1 had 125cc single cylinder two stroke air cooled engine, autolube system, 12V electric start with a push button, 5 speed transmission,  twin shock rear suspension and drum brakes on both wheels. It had a lightweight and flexible chassis, rubber mounted fenders and comfortable seat. Turn signals / blinkers were an optional add-on feature.

Several modifications were made over the coming years. In 1970 the Yamaha AT1B was introduced followed by Yamaha AT1C one year later. For those that wanted to take off road to the next level, a special motocross edition was also designed, the M/MX models. These had some additional performance features, tuned exhaust and kick start only.

1972 Yamaha AT2 was rolled off factory line shortly after and the final version 1973 Yamaha 125 Enduro - AT3, both were off-road modified yet street legal.

The next step in the Yamaha off road bikes was the introduction of the DT Series and the famous Yamaha DT 125
