Yamaha also sponsors several professional ATV riders in several areas of racing, such as cross country racing and motocross. Yamaha has had success in cross country with their YFZ450, ridden by Bill Ballance, winning 9 straight titles since 2000. Yamaha's other major rider, Traci Cecco, has ridden the YFZ450 to 7 titles, with the first in 2000. In ATV motocross, Yamaha has had success with Dustin Nelson and Pat Brown, both who race the YFZ450. Pat Brown's best season was a 3rd place title in 2007, while Nelson has had two 1st place titles in the Yamaha/ITP Quadcross, one in 2006 and the other in 2008.
The Yamaha YZ450F won the AMA Supercross Championship two years in a row, in 2008 with Chad Reed, and 2009 James Stewart. Yamaha was the first to build a production monoshock motocross bike (1975 for 250 and 400, 1976 for 125) and one of the first to have a water-cooled motocross production bike (1977 in works bikes, 1981 in off-the-shelf bikes). Yamaha's first Motocross competition four-stroke bike, the YZ400F, won the 1998 USA outdoor national Championship with factory rider Doug Henry.
