In 1968 Yamaha introduced the DT-1 250. It revolutionized the Dirt Trail Niche of motorcyles. Quick, reliable and inexpensive it shattered all previous sales records for small displacement bikes and created a new generation of dirt bikers. Yamaha hired the best 250 racer they could find, Keith Mashburn who tore up the record books on his Factory DT- 1 and help sell millions of Yamahas. "On Any Sunday" hit in 1969 and the public rushed to the DT-1 as their instant Dirt Tracker.
