Yamaha Introduces New 2012 YFZ450
High-Performance Sport ATV Brings More Power at
CYPRESS, Calif. – September 14, 2011 – Yamaha
Motor Corp., U.S.A., the world’s leading sport
ATV manufacturer, is introducing a new YFZ450
with increased power and performance. The
2012 YFZ450 is priced at $6,799 – approximately
$200 less than the original YFZ in 2004 and more
than $1,200 less than the closest competing
450cc model – making it the most affordable
high-performance 450 ATV on the market today.
“The YFZ’s price is aimed squarely at the many
sport ATV enthusiasts who have been affected by
the down economy and may not be in a position to
purchase today’s premium-priced 450-class
quads,” said Steve Nessl, Yamaha’s ATV and SxS
group marketing manager. “We know these
guys are either still riding or at least still
want to ride, and we want to give them an
affordable option right now.”
The new YFZ features an updated 449cc
liquid-cooled, double overhead cam four-stroke,
five valve engine featuring 95mm bore and 63.4mm
stroke. Yamaha engineers significantly
increased the low- and mid-range power (compared
with the previous 2009 YFZ450 model) by revising
the cam profile and timing and developing new
ignition mapping. The new larger 42mm
Mikuni® BSR carburetor with throttle position
sensor maintains the top-end performance while
improving throttle response and significantly
reducing throttle effort.
“Our core sport customer’s first priority right
now is price, but they still demand performance
and quality,” Nessl said. “Yamaha is able
to combine all of these customer’s priorities in
the new YFZ450.”
The YFZ’s power is complemented by its light
weight, compact steel frame with aluminum sub
frame and its proven handling characteristics.
The new YFZ with its rigid cast aluminum
swingarm and aluminum upper A-arms help keep
weight down while maintaining performance.
The new KYB front shocks feature 9.1 inches of
travel while the rear suspension system uses a
piggyback Showa shock with 10.6 inches of
travel. The new wheel was designed with
the inner lip rolled in increasing rigidity and
allowing a reduction in weight while maintaining
strength, and the new Dunlop® tires (21x7R-10 in
front and 20x10R-9 in back) were designed
specifically for this YFZ. Twin hydraulic
front brake calipers with 127mm discs and a
hydraulic dual-piston caliper 173mm rear disc
bring the stopping power.
The 2012 YFZ also has a ratchet-type five-speed
transmission and heavy-duty clutch adding to the
machine’s improved comfort on long rides.
The standard push-button electric start and
Yamaha flip-style parking brake are added
benefits. Its large capacity air box
features no-tool access to the extra large oiled
dual-foam filter for easy maintenance.
“The 2012 YFZ450 is the right sport ATV for the
right price at the right time,” Nessl said.
“This machine has a powerful, quick-revving
engine in a lightweight and nimble chassis.
Yamaha is more involved in the world of sport
ATVs than any other manufacturer, and the new
YFZ is another way we can support these
The new YFZ450 will start arriving at Yamaha
dealers by the end of September, and it launches
into an immediate pool of parts and accessories
– more than 90 GYTR® items from Yamaha and
countless aftermarket products.
The YFZ450 comes in Black Metallic or all White.
The White models come with the customer’s choice
of one of eleven available free custom graphics
kits from One Industries. More information
