Yamaha YZ250 Bikes

Yamaha YZ250

The Yamaha YZ250 has been around for decades, since its introduction in 1974, and just keeps getting faster. This 249cc liquid-cooled two-stroke engine with Yamaha’s patented Power Valve System (YPVS) exhaust valve offers a wide spread of power that includes about 50 horsepower and about 30 foot-pounds of torque. The bike as a whole has gotten much lighter over the years, especially with help from the now aluminum frame.

The YZ250 has been ridden by many champions, both in racing and freestyle riding. “The King” of Supercross, Jeremy McGrath won the 1998, 1999, and 2000 AMA Supercross championships on a Chaparral Yamaha YZ250. Freestyle heros Jeremy “Twitch” Stenberg and Nate Adams, among others, perform their aerial tricks on the YZ250, as well.
