The '''[[Yamaha]] DT-1''' was a Single Cylinder, Air Cooled, Two Stroke Enduro [[motorcycle]] produced by [[Yamaha]] in 1969. Max [[torque]] was 2.21 ft/lbs (3.0 Nm) @ 5000 RPM. Claimed [[horsepower]] was 21.05 HP (15.7 KW) @ 6000 RPM. 
 
 
 
==Engine==
A 71.1mm [[bore]] x 71.1mm [[stroke]] result in a [[displacement]] of just 250.0 cubic centimeters. 
 
==Drive==
The bike has a 5-Speed transmission. Power was moderated via the Wet multi-discs. 
 
==Chassis==
It came with a 3.25-19 front [[tire]] and a 4.00-18 rear tire. Stopping was achieved via Drum in the front and a Drum in the rear. The front suspension was a  Telescopic fork while the rear was equipped with a Twin shocks. The wheelbase was 54.69 inches (1389 mm) long. 
 
==Yamaha Plays in the Dirt==
In the United States, two types of off-road machine were in use, one for desert racing, the other
for [[enduro]]s in the north-eastern states. The desert sleds, usually twins, demanded brute power
and stability from the machines and strength from the rider to control the weight. The enduros
called for less weight, quick steering and low-down power, so were much as trials models and
used a smaller engine, usually a [[two-stroke]] single.
 
Yamaha saw that there was a major market for a dual-purpose machine, one able to perform
well on the road but equally able to run off-road for fun or in competition. Thus came the trail
machine, which was able to compete in enduros or simply take its owner up to the hills for the
view. Small, light and handy, it could go many places without tiring the rider and Yamaha's first
was the DT1 of 1968, powered by a 246cc two-stroke single driving a five-speed gearbox. It was
the start of a long, and most successful, off-road line.
 
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.

The Yamaha DT-1 was a solid, inexpensive bike you could ride to the track and then run with the best purpose-built dirt bikes of the day once you got there. And even if you weren’t a racer, it was a great compromise bike that could handle almost any trail you threw at it — and still get you safely home at the end of the day.
