anticipated and all-new YFZ450R at its national
dealer meeting in Las Vegas today. The new 2009
model year machine, built to be the world’s

suspension, fuel injection, a no-weld aluminum
frame and an all-new power packed engine set
in a motocross-wide chassis.
Yamaha
ATV History Of Dominance
|
Yamaha has a well deserved reputation of building
the industry’s best sport ATVs. The original
YFZ450 was announced in 2003 as the first race-ready
450-class ATV with leading technology and more
pure sport performance than any machine ever
built at that time. Since then Yamaha has dominated
the field across the board with the best selling
big bore sport ATV in the Raptor 700R* down
to the best selling 250-class machine with the
Raptor 250. But the YFZ is still the pinnacle
of ATV performance, and even with a constantly
growing number of competitors entering the 450
market, the YFZ has always been the top seller
in its class*.
YFZ450R:
MX Width with Cast Aluminum Frame
|
The new YFZ450R meshes this history of dominance
with the latest in Yamaha technology and innovation.
In its stock form, the YFZ450R is the best
all around performance ATV combining racing
technology and features with all-terrain sport
performance. Starting with its motocross track-width,
the YFZ450R is immediately ready for the MX
track. The no-weld cast aluminum frame is
lightweight and has a tension-steel bottom
portion that helps keep the engine as low
as possible centralizing mass for excellent
handling. The cast aluminum frame is bolted
together, rather than welded, for maximum
durability.

YFZ450R Aluminum / Steel Frame is a
first for 450 Class ATVs |
The YFZ450R comes with newly designed front
and rear suspension. The front frame is narrow
at the A-arm mounting points reducing changes
in the camber as the A-arms travel through their
full range of motion. The front 44mm KYB shocks
have Kashima coating for smooth operation and
impact absorption with 9.8 inches of wheel travel.
The gravity-fed aluminum rear swingarm is matched
to a fully adjustable 46mm KYB piggyback shock
affording the rear wheels 11 inches of travel.

Powerfull 449CC Engine with Fuel Injection
|
The YFZ450R has a powerful 5-valve DOHC liquid
cooled single cylinder 449cc engine that uses
the cylinder head and cylinder from the championship-winning
YZ450F. The titanium five-valve cylinder head
comes with camshafts designed just for this
machine that hammers out superior low- to
mid-range torque and pushes through to a high-revving,
hole-shot grabbing top end.
The technologically advanced 450R is also
equipped with electronic fuel injection featuring
a 42mm Mikuni® throttle body, 12-hole
Denso injector system and a Mitsubishi 32
bit ECU, which provides exceptional atomization
of the fuel for maximum power, unrivaled throttle
response and automatic altitude and temperature
adjustment. The system also includes idle
speed control for easy, reliable start-up.
A stainless steel head pipe with a titanium
heat shield and a new oval muffler provide
maximum performance while keeping the YFZ450R
well within current noise guidelines.

Adjustable
Handlebars and Simple Service Access
|
Yamaha Factory Racing experience led to a host
of enhanced features on the YFZ450R. One benefit
is race prep and service made simple. Body panels
come off easily, and there is no need to remove
the battery or other components to take off
the fenders. The oil tank is integrated with
the crankcase so it’s easier to service
the engine.

The
YFZ450R features replaceable high wear
area fender sections, which are also
designed to help reduce rider fatigue
|
The
YFZ450R comes stock with ProTaper bars
with 4 position mounting to allow bar
mounting range of 30mm |
The YFZ450R also boasts ProTaper® handlebars
and all-new four-position adjustability. There
are two sets of holes in the handlebar crown
and eccentric clamps that allow the rider
to choose between the standard setting, 10mm
or 20mm forward, or 10mm back. A newly shaped
thumb throttle lever delivers smooth throttle
control requiring less effort and causing
less fatigue. A new seat design is thin yet
roomy in the front and wider and more padded
in the back for a more comfortable all-around
ride. The YFZ450R also comes with very large
65mm wide foot pegs with kick-ups that provide
maximum traction and added comfort when moving
around on the machine.

Newly
Designed Tires, Disc Brakes and Rider
Comfort

Newly designed Dunlop® tires have a superb
combination of compound, tire profile, tread
pattern and sidewall-to-tread center stiffness
to provide outstanding comfort, bump absorption
and precise cornering performance. At 20 inches
in the rear and 21 inches in the front, the
tires also provide maximum ground clearance
for track, trail or dune riding. The YFZ450R
has excellent stopping power from dual front
hydraulic disc brakes and a lightweight wave-type
rear rotor including dual piston calipers in
the back as well as the front.

in November with an MRSP of $7,999.
