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-GP 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 YZ250F was updated for 2009 with a weight drop of 500g and a new lighter swingarm improving handling along with a redesigned rear hub. For 2010 the bike was again revised with a brand new engine, styling and centralisation of the chassis.
The race-proven production YZ250F is an excellent base with at least five teams fielding the machinery. In 2009 the motorcycle won the extremely competitive MX2 European Championship; the Grand Prix feeder series. Some world championship teams benefit from the acclaimed YRRD (Yamaha Rinaldi Research and Development) race kits with engine modifications. The factory bikes themselves include the following:
