Yamaha is pleased to introduce
the all-new YZ250F.
This extreme performance 4-stroke motocross bike,
weighs less than some 250cc 2-stroke machines.
It has a liquid-cooled dual overhead cam engine with Yamaha's exclusive 5-valve
head design. Each of the engines' five valves is made of lightweight titanium
for quick engine response and dramatic acceleration. The engine is capable of
revving to 13,500 rpm.
The chassis is all YZ. It has an aluminum subframe and fully adjustable
suspension. The YZ250F has the same fully floating front disc brake that is
found on the YZ426F.
Once again,
Yamaha's innovation and leadership in off-road technology shine with this proud
addition to the YZ family.
