2013 Yamaha YFM250R
The 2012 Yamaha YFM250R is a nifty choice for those in search of a very maneuverable off-road machine with the attitude of a true racing quad. The quarter-liter engine is much punchier than you'd expect and is designed to be ridden hard. Together with the revised geometry of the frame and suspension, the triple hydraulic disc brakes are providing a smooth, predictable ride even on the most unwelcoming terrain, while at the same time being easy to set up for weekends at the dirt track.
Also comes in a homologated version for registration, therefore it can also be used on public roads.
