Overview
Honda CRF 450L
This is the bike so many have been waiting for. The one serious riders have dreamed about. A true street-legal dirtbike that offers the reliability, refinement and quality of a Honda, along with the light weight, handling, and power of our best off-road machines. Introducing the new 2019 CRF450L. Sure, youve seen dual-sport bikes before, but this is something much, much more: a true trail-to-trail machine.
Developed in tandem with our all-new 2019 CRF450X, it features a powerful 449cc Unicam engine, twin-spar aluminum CRF chassis, six-speed transmission, and premium suspension. Electric start? Naturally. All-LED lighting package? Of course. Until now, youve always had to choose between performance and reliability. No longerwith the CRF450L, you get the best of both worlds. And best is a word youre going to hear a lot when youre talking about this bike.
Features
Engineering
Fully Street Legal
The CRF450L is equipped with a catalytic
converter and is fully street legal in all 50 states. That means you can ride it
wherever its legal to operate a motor vehiclein state and national parks, on
the road, on public lands. Plus, you dont need to haul your bike to the
trailhead in a truck or on a trailer. Best of all, it makes finding gas a
breeze.
Electric Start
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.
Six-Speed Transmission
Like our CRF450X, the CRF450L rocks a
six-speed gearbox. That gives you a low gear perfect for tight, slow situations,
and a top gear thats tall enough for highway riding to the next gas stop or
trailhead.
Lithium-Ion Battery
Light, compact, and offering excellent
performancejust like the CRF450L itself! Conventional batteries are heavy, but
not this premium piece. Its all part of why your new CRF450L performs as well
as it does.
Inertia-Tuned Crank
We redesigned the CRF450Ls crank to have 13
percent more inertia than the CRF450X. Why? To smooth out power delivery and
make the engine more user-friendly in tight, technical situations.
Dual Radiators
The CRF450Ls 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 mass, and the tank is protected by a
plastic skid plate.
Final-Drive Sprocket Damper
Designed to keep your bike quieter while not
adding any weight, these unique drive sprockets are just another example of the
CRF450Ls innovative engineering.
Electric Fan
The CRF450L is a ride anywhere type of bike,
and because conditions vary so widely, weve equipped it with a light electric
fan for the radiator. Rock crawling or riding on a hot Arizona single-track, it
helps keep your engine running cool.
Titanium Fuel Tank
Holding 2.01 gallons, the CRF450Ls premium
titanium tank is light and tough.
Skid Plate
The CRF450Ls factory skid plate is light, yet
also offers the engine and lower-frame protection serious riders demand on a
machine like this.
LED Headlight
The CRF450L features an all-LED lighting
package, including the headlight. Thats a big deal, because it takes a lot of
weight off the front end. And the lighting pattern is also specially designed
for both on- and off-road situations.
LED Taillight
The LED taillight is integrated into the rear
fender. Its light, compact and rigid.
Performance
449cc Unicam Engine
Hondas 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 Valves
Lightweight titanium intake valves permit use
of smaller valve springs, reducing overall engine height.
Fuel Injection
The CRF450L features our proven fuel-injection
system. Its part of the reason the CRF450L 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
Twin-Spar Chassis
This is the same design as our all-new CRF450X
uses, and thats a really big deal. It means the CRF450L is a true off-road
bike, and not some compromise. The twin-spar aluminum frame is both light and
stiff, and provides the basis for the CRF450Ls excellent handling. The chassis
geometry is specially selected for responsiveness, and also is wider than the
standard MX frame to accommodate the six-speed transmission.
IRC GP Tires
The CRF450Ls tires give you good off-road
traction and on-road life. Tires are always a critical part of any on/off-road
bike, and weve hooked you up with some great ones here.
Low Center of Gravity
The compact Unicam engine and Hondas famous
concentration on center-of-mass engineering help keep the CRF450Ls 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 combined with an integrated rear master-cylinder and fluid
reservoir, a set-up that eliminates the separate reservoir and hose.
18-Inch Rear Wheel
The CRF450Ls 18-inch rear wheel gives you an
excellent choice of on/off-road tires.
Comfort
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 engines massive torque, while carefully matched
clutch springs provide a light feel at the lever.
Renthal Fatbar
Aluminum Renthal Fatbar is rubber-mounted to
help reduce rider fatigue and improve comfort.
Works MX Styling
Having a hard time spotting the differences
between our factory MX bikes and the new CRF450L? Youre excused. The L looks
like our MX bikes because its derived from themthe smooth bodywork makes it
easy to move around, and the in-mold graphics not only look cool but are
durable, too.
Black Rims
They may not help you go faster, but the sweet
black DID rims sure look good.
Superior Ergonomics
Placing the riders 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 CRF450L uses. Tucked up high and out of the way,
this forged alloy piece is just another example of how the CRF450L gets it
right.
