2008THE DUNES AT PISMO OR GLAMIS. The MX
course at Budds Creek. The dusty, fifth-gear
fire roads of the Baja 1000. The mud of the
GNCC courses on the East Coast. And that red,
red Georgia clay. There’s nothing like riding an
ATV with a potent engine, perfect suspension
and a wide-open trail in front of you. What’s
keeping you from living that dream?
PERFORMANCE YOU CAN COUNT ON When
most people think about Honda all-terrain
vehicles, they probably think about dependable,
hard-working machines for the ranch or farm.
And we build plenty of those too. But when it
comes to our sport ATVs, it’s all about one thing:
performance. And that comes from a level of
engineering that nobody can match.
AMA Pro MX Champion. AMA Hare and Hound
Champion. WPSA Pro Quad 450 Champion.
BITD Champion. SCORE Desert Series Cham-
pion ( just to name a few). It’s like Honda engi-
neers designed some sort of trophy magnet and
tucked it into the crankcase. In reality, it’s more
simple: light weight, great power and great
handling, all in a balanced machine that just
plain works better than anything else out there.
TRX450R Ever since the Honda TRX®450R rolled up to the starting gate, it’s sent all the pretenders to the sport-ATV throne
slinking back to the pits. With championships in every major ATV discipline, it’s the machine serious racers choose.
And it’s easy to see why: Just look at some of the 450’s features. An electric starter kicks the high-revving short-stroke
engine to life (we still make a kickstart-only model if you’d prefer). A flat-slide carburetor and a 12.0:1 compression ratio are
almost guaranteed to give you the holeshot and let you stretch that lead all the way to the finish. Long-travel suspension,
lightweight steering knuckles, triple disc brakes and premium shock absorbers all add up to performance that’s unparal-
leled. Because it’s a Honda, even if you’re not racing at ten-tenths, you can still have a great time just sport riding on your
favorite trails. And check out the cool color schemes we have this year!

TRX400EX Built around one of the
best ATV engines we’ve ever pro-
duced—a big-bore air-cooled dry-
sump design—the TRX400EX is a pure
competition-grade machine that’s
great for sport-ATV riding. Bulletproof
engine, superior suspension, disc
brakes, reverse—you’ve got it all here.
And it’s packaged in new bodywork
that’s sure to turn heads.
TRX300EX If you’re a sport or
sport-recreational rider, you can get
agility, power and value in one ATV.
You get a high-output SOHC four-
stroke, double-wishbone independent
front suspension, a manual five-speed
transmission and an electric starter—
along with sharp styling and an
easy-to-use reverse.

feature everyone can appreciate.
SHAFT FINAL DRIVE Perfect
for recreational riders, the
TRX250EX uses a strong,
maintenance-free shaft-final-
drive design.
DRY SUMP Our TRX400EX

(shown here), while the TRX450R
uses a twin-sump design. Both
improve performance.

with an easy-to-use reverse, for
unloading or getting out of
tight spots.

TRX90EX Need the perfect-sized
ATV for your young Red Rider? Then

engine and a four-speed transmis-
sion (the latter featuring our no-
clutch shifting), it has plenty of
power. And because it’s a Honda,
you know that it’s going to run just
about forever—a big plus when your
kids want to ride. It sips gas and

an ATV your kids will love.

BE A RESPONSIBLE RIDER ATVs can be hazardous to operate. Remember, always wear a
helmet, eye protection and protective clothing whenever you ride, and never ride on paved surfaces
or public roads. Never carry passengers, and never engage in stunt riding. Avoid excessive speeds,
and be particularly careful on difficult terrain. Never ride under the influence of drugs or alcohol. The
TRX450R, TRX400EX and TRX300EX are recommended only for highly experienced riders 16 years
of age and older. The TRX250EX is recommended only for riders 16 years of age and older. The
TRX90EX is recommended only for riders 12 years of age and older; riders younger than 16 years of
age must be supervised by an adult. Honda recommends that all ATV riders take a training course
and read their owner’s manual thoroughly. New ATV purchasers should take advantage of free ASI
training and completion incentives. For safety or training information, see your Honda Dealer or call
the ASI at 1-800-887-2887.
Whenever you ride off-road, make sure you follow all the “TREAD LIGHTLY” guidelines, and always
stay on established trails in approved areas. Keep your riding areas clean, use common sense,
and respect the rights of others. Never modify your silencer or spark arrestor. Always obtain written
permission before riding on private lands, and obey all the laws and regulations governing your
riding areas.
