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

A fresh idea

Looking it seems simple enough: a lightweight but strong frame, put moderately-long-travel suspension under it, add dual-sport tires, throw in a and reasonably powerful engine, add the legal bits, and then it for a good deal less the nearest true dirt Presto, instant hit.

Up until that point, had figured that out, and the introduction of the Yamaha DT-1, essentially defined a new market for Savvy research had shown was a market for this type of in the U.S. but even Yamaha was by the enthusiasm American buyers for its new bike: The initial 12,000 run sold out quickly, so Yamaha up production immediately, selling of its little dirt bike the rest of the industry played

The wheelbase was a 53.5 inches, with suspension duties handled by a steel swingarm and dual with four inches of In the front, standard telescopic offered six inches of travel.

From the the rims were wrapped specially-designed Dunlop dual-purpose tires (4 inches wide in the 3.25 inches for the front) were adequate for light-duty work, but were immediately for true knobbies for serious duty.

Other than acceptable and solid reliability, the main between the DT-1’s engine and bikes was Yamaha’s Autolube system, which most helped it appeal to new motorcyclists who want to deal with fuel and oil. The Autolube also helped with and reduced the typical 2-… by ensuring proper oil mixture. also focused on making the as narrow and light as possible to the bike nimble.

The low-mounted aluminum fender was often scrapped for an high-mounted plastic unit for serious off-road use.

Overall the styling was subdued. The year’s pearl-white tank and nacelle were replaced in years by brighter colors. fork sliders and engine all gray. Chrome wheels, heat shield, handlebars and bezel brightened things up a and the candy-red tank badge the otherwise almost monochrome a splash of color.
