YFZ450 SE
KEY FEATURES:
1 . The YFZ450 Special Edition with hi/lo-speed adjustable
piggyback shocks now comes with all-black with red flames graphic
package or hot flaming graphics.
2 . Front and rear piggyback shocks adjust for high- and low-speed
compression damping—as well as rebound damping and spring
preload.
3 . The lightest, most powerful ATV ever, winner of just about every
magazine shootout, 2005 GNCC and Quadcross Championships, and
ATV Illustrated's Sport ATV of the Year (a tie with our own Raptor
700R).
4 . Most powerful industry-exclusive five-titanium-valve engine and
350-pound dry weight give the YFZ450 the best power-to-weight
ratio of any ATV ever produced.
5 . Ultra-compact, lightweight, high-tensile steel frame with fully
adjustable suspension means YFZ450 is also the best handling race
bred ATV ever produced.
