to commemorate the 60th anniversary of the company in
America. The 60th Anniversary Editions of the YZ250F and
YZ450F will sell for $100 more than their standard-edition
counterparts. Both of those will keep the same prices as
last year—$7590 for the 250 and $8590 for the 450.

different mapping and new cam profiles. There are also
changes to the clutch boss, the water-pump impeller and
the shifting mechanism. The chassis gets a 270mm front
brake rotor, new suspension settings, different motor mounts and a
slightly different frame construction above
the swingarm pivot. The footpegs are 5mm
lower, and the triple clamp offset is increased
from 23mm to 25mm.
