Built To Dominate Off Road
Life is full of compromises—unless you're riding a Honda
CRF450X. What we've done here is take the light weight, responsive
handling, and cutting-edge performance of our CRF450R motocrosser and
put it into an awesome off-road package that doesn't give up a thing. In
fact, we think it makes the CRF450X better in every way for the serious
off-road rider. You get a legendary engine tuned for the way
off-roaders ride, a wide-ratio six-speed gearbox, aluminum chassis,
electric starter, and long-travel suspension. And this year there are
new handguards, and a super-crisp new styling and graphics package.
Factory riders and privateers use this machine to get to the top of the
podium in Baja. You're going to find it turns your weekends into you own
private podium performances, too.
Engineering Features
- Wide-Ratio
Six-Speed Transmission: Having six speeds in the CRF450X's transmission
compared to an MX bike's typical five gives you more choice, and makes
this versatile bike even more versatile. You have a gear for everything
from east-coast rock crawling to wide-open Baja blasts.
- Lithium-Ion
Battery: Light, compact, and offering excellent performance—just like
the CRF450X itself! Conventional batteries are heavy, but not this
premium piece. It's all part of why your new CRF450X performs as well as
it does.
- Tuned-Weight
Crank: The CRF450X gets a special crankshaft, different from our CRF450R
MX bikes and our CRF450L dual-sport. Why? The crank's weight and
inertial character make a huge difference in how a bike delivers power. A
crank is expensive, but it's no place to scrimp and try to save—with
the CRF450X, power delivery is just what you want.
- Dual
Radiators: The CRF450X's dual radiators feature a refined core area for
superior heat dissipation compared with conventional dual-radiator
designs. A coolant recovery tank is located in front of the engine
between the frame downtubes for improved center of gravity, and the tank
is protected by a plastic skid plate.
- Titanium Fuel Tank: Holding 2.0 gallons, the CRF450X's premium titanium tank is light and tough.
- Skid
Plate: The CRF450X's factory skid plate is light, yet also offers the
engine and lower-frame protection serious riders demand on a machine
like this.
- Lighting Package: Your CRF450X comes equipped with a complete lighting package (headlight and taillight) for riding at dusk.
Convenience Features
- Electric
Starter: An electric start system ensures trouble-free starting in all
conditions. The electric starter also drives the clutch side of the
crankshaft to provide superior lubrication to starter gears while
producing a narrow engine with a short, strong crank.
Performance Features
- 449cc
Unicam® Engine: Honda's Unicam® cylinder heads combine the best of
single- and double-overhead-cam designs. The configuration contributes
to a compact engine that saves weight over a comparable
dual-overhead-camshaft motor and also permits a narrow included valve
angle. This flattens the combustion chamber to facilitate ignition flame
propagation, allowing a high compression ratio. Since less space is
taken up in the cylinder head, the camshaft sits lower in the head for a
more compact engine and a lower center of gravity.
- Titanium
Intake And Exhaust Valves: Lightweight titanium intake and exhaust
valves permit use of smaller valve springs, reducing overall engine
height.
- Fuel Injection: The
CRF450X features our proven fuel-injection system. It's part of the
reason the CRF450X offers such excellent torque and spot-on metering and
response, especially in the critical low-rpm range. It also
automatically compensates for elevation and weather changes.
Handling Features
- Twin-Spar
Chassis: The CRF450X uses a twin-spar aluminum chassis that takes
advantage of all the lessons we've learned on the MX track and from
winning countless Bajas. The frame is both light and stiff, and provides
the basis for the CRF450X's excellent handling. The chassis is also
wider than the standard MX frame to accommodate the six-speed
transmission.
- Dunlop Mx52
Tires: The CRF450X's Dunlop MX52 tires give you good superior off-road
traction in a wide variety of terrain and conditions. Tires are always a
critical part of any on/off-road bike, and we've hooked you up with
some great ones here.
- Low
Center Of Gravity: The compact Unicam engine and Honda's famous
concentration on center-of-mass engineering help keep the CRF450X's
center of gravity low. That means the bike feels lighter, and it helps
handling too.
- Works-Style
Front Brake: Compact twin-piston front brake caliper, anodized-aluminum
brake pistons and lightweight 260mm front disc offer great stopping
power while minimizing unsprung weight for improved turning and
handling.
- Works-Style Rear
Brake: HRC works-type rear brake system uses a 240mm brake rotor to its
integrated rear master-cylinder and fluid reservoir, a set-up that
eliminates the separate reservoir and hose.
- 18-Inch
Rear Wheel: The CRF450X's 18-inch rear wheel gives you an excellent
choice of off-road tires. Plus, the black DID rims look great too.
Comfort Features
- New
Handguards: You asked; we listened. The 2021 CRF450X now comes with
factory handguards as standard equipment. Exclusively designed for the
off-road rider and manufactured to Honda standards, they help protect
you from rocks, branches, thorns and brush. Plus, it gives your CRF450X
that “finished" look, right from the start.
- Gear-Driven
Counterbalancer: The Gear-Driven Counterbalancer reduces vibration and
drives the water pump. Eight clutch plates provide the surface area
necessary to handle the engine's massive torque, while carefully matched
clutch springs provide a light feel at the lever.
- New
Works MX Styling: For 2021, we gave the CRF450X some super-crisp new
styling and graphics. The “X" looks like our MX bikes because it's
derived from them—the smooth bodywork makes it easy to move around, and
the in-mold graphics not only look cool but are durable, too.
- Superior Ergonomics: Placing the rider's legs at the narrowest part of the frame helps improve comfort and handling.
- Sidestand:
Hey, a sidestand may seem like no big thing, but take a look at the one
the CRF450X uses. Tucked up high and out of the way, this forged alloy
piece is just another example of how the CRF450X gets it right.
- Fuel
Mileage Meter: An important feature for planning gas stops and
calculating your bike's range under varying conditions, the Fuel Mileage
Meter shows current fuel mileage and average fuel mileage as well as
fuel consumption. Displays in either miles or kilometers, and applies to
both the A and B tripmeters. The Fuel Mileage Meter is in the same
digital instrument display as the speedometer, odometer, tripmeters and
digital clock.
