| YZ450Fs new
rearward-slanted cylinder is a revolutionary advancement
that achieves unmatched mass centralization, concentrating
inertial mass toward the center of the machine.
This bold new design also swaps traditional intake
and exhaust positions, putting the lightweight
airbox and throttle body out front. This contributes
to mass centralization for nimble handling while
also achieving a straight intake tract for superb
combustion efficiency that delivers more power. |
