Featuring a lightweight long-stroke engine that delivers an instant hit of free-revving power, the YZ250 is today’s ultimate 2-stroke race bike.
And for 2009 the bike’s high-tech aluminium chassis comes with new lightweight wheel rims that reduce unsprung weight for enhanced handling and suspension performance. New speedblock graphics give that factory look – and a special new seat design delivers just the right balance of grip and rider mobility.
With its punchy 2-stroke power, superb agility and low weight, the latest YZ250 is built to deliver a unique and exciting riding experience.
YZ250. The genuine original.
