There are few joys in life equal to the free-spirited thrill and experience of motorcycling. And that’s why it’s important for all of us to do our part as responsible riders. By following logical,
commonsense rules, we can maintain season after season of unparalleled enjoyment of our sport. Always remember to review your Yamaha Owner’s Manual and Tips Booklet before you
ride. Before each ride, take time to check all your equipment. Always wear an approved helmet, eye protection, long-sleeved shirt, long pants, gloves and boots. And always be sure your
bike is in first-class condition before riding. Never ride an off-road motorcycle on paved surfaces or public roads; never carry passengers; never engage in stunt riding and avoid excessive
speed. Provide parental supervision when a motorcycle is being operated by a minor. Every motorcycle rider should be aware of the limits of his or her skills, experience and abilities and
ride accordingly. Beginners should be extremely cautious and allow extra time and distance for maneuvering and braking. All riders should ride well within the limits of their abilities,
never beyond them. Do not drink and ride. It is illegal and dangerous. Yamaha and the Motorcycle Safety Foundation encourage you to ride safely and respect the environment. For further

2013 YZ450F
>> REARWARD-SLANTED ENGINE >> FUEL INJECTION >> ALUMINUM DOUBLE “S” FRAME
OTHER BIKES, PLEASE MOVE TO THE REAR.
The revolutionary YZ®450F is the first and only production bike ever built around a straight-intake, rear-slanted
engine and aluminum bilateral beam frame for the most compacted center of mass ever in a four stroke. Plus, the
4-titanium valve cylinder head is matched to a newly optimized fuel injection system that provides superb low- to
mid-rpm power feeling. The result: instant throttle response, unprecedented balance and incredible cornering
performance, coupled with the best stock suspension in the industry and legendary Yamaha durability. Note to the
MX world: If you’re not ready for the future, prepare to be passed.
BILATERAL BEAM ALUMINUM FRAME: Torsional rigidity converts lateral impacts into
longitudinal forces, which are easily absorbed by the suspension—so you’re quick into the corners and
even quicker coming out.
REARWARD-SLANTED ENGINE: Concentrates the engine’s mass much closer to the YZ’s center
of gravity, enabling lightweight handling, quicker direction changes and a straight intake tract for superb
combustion efficiency that delivers more power.
4-VALVE CYLINDER HEAD: The 4-titanium valve cylinder head is matched to a newly recalibrated
fuel injection system that provides superb low- to mid-rpm power feeling. Instantly adapts to changing air/
fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions.
BATTERYLESS FUEL-INJECTION SYSTEM: The YZ450F was engineered around its fuel
injection system: Moving the intake to the front of the bike makes the straight intake not just possible
but amazingly effective.
GYTR® POWER TUNER: Allows you to quickly adjust the fuel and ignition maps to suit riding conditions
and rider preference. Allows 9 easy-to-program adjustment points for both the fuel and ignition maps.

TORNADO PIPE
Further aids handling by allowing
the fuel load to be carried lower and
more rearward.
The rearward-slanted engine allows for
straight intake and exhaust ports, creating
the most direct path for airflow into the fuelinjected engine for incredible performance.
Length tuned for low-rev grunt and top-end
horsepower, with a torque-boosting resonator
that keeps the noise down to 94 dB.

YZ250F 2013
>> OPTIMIZED ENGINE >> BILATERAL BEAM FRAME >> RACE-SPEC SUSPENSION
THE MOST POWERFUL, BEST HANDLING YZ250F EVER.
Designed to be the best cornering performance motocross bike ever, the 2013 YZ®250F features a long list of top-tier features.
We started with a refined, optimized engine that pumps out power in the 8,000 to 12,000 rpm range; gave it a Bilateral Beam
frame with revised rigidity balance for superb cornering performance and stability on rough, high-speed straights; added a
KYB® suspension for superior handling; then threw in a host of other goodies like beefy outer fork tubes and triple clamps for
the most powerful, best cornering, lightest weight in its class, most durable and intuitive YZ250F ever.
BILATERAL BEAM FRAME: Sixteen separate components, advanced structural analysis plus high
lateral and torsional rigidity for added cornering stability and more cornering speed.
GREAT MID- TO TOP-END POWER: Engine refinements, including a large 39mm carburetor,
optimized CDI and light piston with a light piston pin, mean the YZ250F has more power as well as exceptional
throttle response in the mid- to high-speed range.
STRENGTH IN NUMBERS: Strong transmission gears and shift fork make for smooth shifting
and durability. Stiff clutch springs cope with that 250 four-stroke power, while the lever ratio keeps
clutch-pull effort low.
HYDRO-FORMED SWINGARM: A super-light, super-rigid, hydro-formed swingarm and a strong,
25mm axle are carefully tuned to complement the YZ250F’s advanced chassis.
LEADING-EDGE STYLE: Form follows function with fenders, number plate, fork protector,
side covers and air scoop. The seat serves up even more feel and feedback. Rich-looking black rims
and gold-color drive chain complete the package.

Rumors of the two-stroke’s demise have been greatly exaggerated. In fact, some race organizations allow 250cc
two-strokes to compete against four-strokes in amateur competition, so there is no doubt we’ll all get to hear that
sweet sound at the track. Good thing the 2013 YZ®250, YZ®125 and YZ®85 are more prepared than ever with their
superior chassis designs, explosively powerful engines and awesome lightweight handling. We’re there for you,
ahead of the pack, two stroke or four.
SERIOUS POWER: YZ250 and YZ125’s patented YPVS™ power-valve systems broaden and smooth
power delivery: You get immediate off-idle response, smooth midrange and strong top-end power with
plenty of over-rev.

TOPLINE COMPONENTS THROUGHOUT: YZ250 and YZ125 roll with aluminum frames, tapered
oversized handlebars, wave-type brake discs—they’re ready to run up front straight from the crate.
MINI OF CHOICE: The YZ85 is world renowned as the most serious mini-missile out there:
an aggressive, quick-turning 157-pound machine packing a hard-hitting, take-no-prisoners powerplant.
The liquid-cooled, 85cc crankcase, reed-valve inducted 6-speed is light, compact and designed to deliver
hard-hitting, moto-winning power throughout the rpm range.
WAVE-TYPE ROTORS
Light and tough wave-style brake
rotors, front and rear, offer great feel

WIDE FOOTPEGS
Very wide pegs give you all kinds of
boot grip and leverage on the bike.
There are lots of cool things about the WR®450F. But perhaps the coolest is that it uses a light, compact, YZ250F-based
chassis but gets all the serious power of a highly potent, fuel-injected 450 engine. And that’s just the beginning.
Designed to perform on the tight trails and in the highest altitudes, the fuel injection system delivers smooth power
and lightning-fast throttle response. Inspired by Yamaha MX race technology, right down to its agile chassis and
cushy YZ250F-based suspension, it doesn’t just pound the trails—it pummels the competition.
MX-INSPIRED CHASSIS: Say hello to an off-road bike that thinks like a motocross bike.
Incorporating award-winning Yamaha race technology, the nimble WR450F boasts a compact 250cc chassis
for lightweight handling through the tightest woods.
PLUSH SUSPENSION: Serious riders need the latest and greatest suspension. That’s why the 2012
WR450F comes with the same fork and shock as the YZ250F (valved and sprung for off-road use, of course).

computer for race time keeping, as well as a speedometer, clock and tripmeter, you’ve got bells and whistles to spare.
