The Big Bear has long been a mainstay in the
Yamaha utility ATV line up offering riders the
option of not only selecting when 4WD was
required, but also what gear was best for their
usage – either fun or work. Many Big Bear fans
are also “fans” of the mud whether they are
seeking it out for fun or that’s what their
property offers up. The Big bear has always been
a leader in the mud category, but we can all
agree that the additions of independent rear
suspension (IRS), fully-locking differential and
a host of other mud-friendly updates will take
the 2007 Big Bear to the next level.
For 2007, the Big Bear 400 features the
proven air-cooled, torque-producing 386cc SOHC
four-stroke engine with great low- to mid-range
power, which riders know and love. 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 continues for as do
the dual hydraulic brakes in the front. However,
for 2007 the rear brakes get an update – a
high-tech sealed wet brake in the rear provides
consistent, long-lasting performance regardless
of the conditions. The new rear brake system
coupled with the addition of diff lock to
2WD/4WD the On-Command® system and the all-new
IRS make this one mean bear in the mud or
through any nasty terrain you may stumble upon
during your travels.
For 2007 the addition of the IRS system on
the Big Bear means a more terrainable bear
overall. The travel of the IRS system now
matches that of the independent suspension up
front – 5.9 inches. Both feature independent
double wishbone suspension with five-way preload
adjustment allowing riders to choose the setting
that’s best for them, especially if they are
hauling a heavy load. And, the IRS system means
better overall ground clearance of XX more than
XX inches than the previous Big Bear.
Of course, if mud is what your after, you’ll
also appreciate the all-new ITP Mud Lite tires,
high-mounted air-intake and all-new full
floorboards, which not only offer superior mud
protection, but also all day comfort.
All of these additions mean one great
handling bear not only in the mud but also on
tight trails. The Big Bear 400 quickly reacts to
rider input and can maneuver through some of the
trickiest terrain around. Even on wide-open
trails, you’ll appreciate the handling,
especially if you are towing loads of up to 904
lbs. via the center-mounted rear hitch. The Big
Bear can haul even more thanks to Duragrip-coated
steel racks, which are capable of carrying a
total of 264 additional lbs. (88 lbs. front, 176
lbs. in the rear). Plush suspension gives the
bear an amazing 9.7” of ground clearance to make
overcoming obstacles a breeze.
Riding comfort is an important factor in
buying any ATV, and the Big Bear 400 5-Speed 4x4
IRS treats its operator to a cushy ride with a
specially designed padded seat, wide fenders and
inner fender guards that help keep mud and
debris off the rider. A large capacity 4-gallon
tank keeps it going strong all day long, 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
brings along the comforts of home to power up
cell phones and other portable electronic
devices.
The 2007 Big Bear 400 5-Speed 4x4 IRS is
available in Hunter Green, Steel Blue and Red at
Yamaha dealerships nationwide starting October
2006. For 2007 the Big Bear 400 5-Speed 4x4 IRS
will also be available in Realtree Hardwoods®
High Definition Camouflage in October 2006.
As if all these updates weren’t enough, the
2007 Big Bear 400 5-Speed 4x4 IRS will also come
in an Exploring Edition. The Exploring Edition
will feature overfenders for additional mud
protection, plastic hand guards, a rear rack
extender and front rack bag aboard a Steel Blue
machine. The Exploring Editions will hit Yamaha
dealerships in October 2006.
