…from when we compared the 2009 YZ250 with a batch of same-sized thumpers during our 2009 250 Motocross Shootout . Our day of testing at Milestone MX had soft, moist dirt all around – perfect for the zingy YZ – and soon our concern was trying to keep the front end down. Yamaha uses a 66.4 x 72mm…

Aimed primarily at saving weight and sharing a parts bin with the YZ-F line, nothing mechanical has been changed on the '09 YZ models. The front tire on both is now the Dunlop D742FA, which…

…one of the riders who favors the 4-stroke. The YZ was just too unpredictable for him and the confidence and precise control allowed by the 250F is ultimately a better fit.

…Dunlop's excellent 739s. ""The lack of power on the bottom-end of the 125 is painfully obvious,"" continued Hutchison. ""It sure is easy to ride that 250 though, just motor around and do whatever you want."" The YZ125, although acknowledged as one of the best 125s, sat longer in the pits than the 250F…

…of going the twin-spar perimeter route like Honda and Kawasaki, Yamaha opted to utilize a similar style to that of its own aluminum-framed 2-stroke YZ line, which is a variation of a traditional double-cradle frame design. Nine pieces of forged, cast and extruded aluminum combine to give this year's…
