CYPRESS, Calif. – June 6,
2008 – The 2009 Yamaha Big Bear 400
independent rear suspension (IRS) 4x4 is the
latest in a long line of tough, trusted and
dependable machines often looked to for long
days of working and fun.
The Big Bear 400 features Yamaha’s proven
air-cooled, torque-producing 386cc SOHC
four-stroke engine with great low- to mid-range
power. The Mikuni 33mm BSR carburetor
feeds the engine and offers excellent throttle
response and great overall performance.
The popular five-speed semi-automatic
transmission with reverse is one of the features
that makes the Big Bear a favorite as it allows
the rider to choose the best gear for the job
and terrain ahead. Another important
feature – especially when hauling, towing or
riding in muddy conditions – is the dual
hydraulic brakes in the front and a high-tech
sealed wet brake in the rear that provide
consistent, long-lasting performance regardless
of the conditions. The rear brake system
coupled with the 2WD/4WD push button On-Command®
system and IRS make this one mean bear in the
mud or through any tough terrain.
With 5.9 inches of travel up front and in the
rear, riders will find a plush ride on this mean
machine. Both the front and rear feature
independent double wishbone suspension with
five-way preload adjustment allowing riders to
choose the best setting -- especially useful
when hauling a heavy load. Overall, the
Big Bear 400 offers 10.5 inches of ground
clearance over tough trails and big ruts.
Other key features for muddy conditions include
the ITP Mud Lite tires, high-mounted air-intake
and full floorboards, which not only offer
superior mud protection but also all day
comfort.
The Big Bear 400 quickly reacts to rider input
and can be maneuvered through tricky terrain.
The vehicle can also handle heavy loads towing
up to 904 pounds via the center-mounted rear
hitch. But this bear doesn’t stop there;
the Duragrip-coated steel racks are capable of
carrying a total of 264 additional pounds (88 on
the front and 176 on the back).
Riding comfort is an important factor in buying
any ATV, and the Big Bear 400 treats its
operator to a cushy ride with a specially
designed padded seat, wide fenders and inner
fender guards that help deflect mud and debris.
A large capacity 4-gallon fuel tank keeps it
going strong on a long day, while a speedometer
and odometer/trip meter allows enthusiasts to
track their progress while either on the job or
at play. A mud-resistant DC outlet can power up
cell phones and other portable electronic
devices.
The 2009 Big Bear 400 IRS 4x4, with an MSRP of
$5,799, is available in Hunter Green, Steel Blue
and the new Black Metallic color at Yamaha
dealerships nationwide in September 2008.
The Big Bear 400 IRS 4x4 will also be available
in Realtree™ AP HD® Camouflage for $6,149 in
June.
