Yamaha DT-1

The Yamaha DT-1 is a 250cc, single cylinder, two stroke, reed valve, dual-purpose motorcycle manufactured by Yamaha starting in 1968. The DT-1 made a huge impact on motorcycling in the US because it was truly dirt worthy. Light, simple, inexpensive, and importantly, supremely reliable, the DT-1 sold by the thousands. This machine introduced more people t o off-road and fun riding than any other. For the racer, Yamaha offered a GYT kit (Genuine Yamaha Tuning) that increased engine power to 30 bhp. Individual companies offered a staggering array of accessories, so its rare to find a stock version today. The Enduro put Yamaha On/Off-Road motorcycles on the map in the US.
