YZ250F
Yamaha’s YZ250F is a legendary bike in the off-road world, creating a new class of motocrosser (the 250cc four-stroke) since its inception in 2001, paving the way for the latest generation of MX2 class machines.

The YZ250F was an instant hit on its world championship introduction in 2003, dominating the second half of the 125 championship with Stefan Everts and claiming eight from nine races, scooping the manufacturer’s crown. In the first year of the MX2 category in 2004 the bike was again gracing the top step of the podium. The following campaign Italian Antonio Cairoli obtained a maiden title for the machine on an YZ250F prepared by famed tuner Claudio de Carli. He repeated his success in 2007 after finishing runner-up in ’06.

The race-proven production YZ250F is an excellent base and still sets the standard in the class with at least five teams fielding the machinery. Some of those GP squads benefit from the acclaimed YRRD (Yamaha Rinaldi Research and Development) race kits, which involve engine modifications. 

Updates for 2009 include a weight drop of 500g with a new lighter swingarm improving handling along with a redesigned rear hub.
