2019 Honda CRF450R
The industry's best-selling
motocross bike, victor at the 2018 Daytona Supercross at the hands
of Team MotoConcept Honda's
Justin Brayton, and also winner of four media shootouts, the
CRF450R receives a host of updates for 2019, making it lighter
and more powerful. Because converting the "Absolute Holeshot" into
moto wins requires more than just added performance, rider comfort
has been increased through the addition of adjustable mounting
positions for the new Renthal Fatbar® handlebar. With the 2019
CRF450R's all-new black rims and its unique, in-mold graphics,
celebrating on the podium never looked so good.
Heat after heat, race after race, Honda's CRF450R is hooking up
riders like never before. If there's ever a machine that's given
you an almost uncanny holeshot advantage, this is it. And for 2019,
we've taken this awesome open-classer and made it even better. How?
For starters, it's even lighter. Then there's an all-new chassis
and swingarm, designed to work together for increased traction and
cornering. The engine features longer head pipes for better
throttle response and top-end pull. New fuel-injection settings
spray twice per cycle to better atomize the fuel. And for the first
time ever, there's a special launch-control setting, so it's easier
than ever to grab the holeshot and hang on to your lead. What else
is new? Plenty. The 2019 CRF450R-better than ever.
Looking for the ultimate 450? Then check out our new CRF450R Works
Edition. You get all the improvements of this year's bike plus a
special hand-ported cylinder head, black DID LT-X rims, an
exclusive Yoshimura muffler, titanium nitride-coated lower fork
legs and shock shaft, an RK gold chain, special ECU settings, black
triple clamps, revalved suspension, a factory-spec gripper seat,
and full-on HRC decals. The only thing missing is a factory
contract!
Engine/Drivetrain
449cc single-cylinder engine with Unicam® cylinder head, downdraft
intake tract, and electric start offer unparalleled "Absolute
Holeshot" performance
Updated cylinder-head design, with changes near the exhaust ports,
achieves improved exhaust efficiency and contributes to increased
power across the rev range
Revised clutch lifter and pressure plate allow optimum oil supply
to clutch plates and friction discs, resulting in enhanced
durability
New scavenge-pump design features two 12mm pumps, up from a single
16mm pump, for increased lubrication and reduced friction in the
engine, improving peak performance and enhancing over-rev
characteristics
All-new piston oil jet uses five nozzle holes and a refined pattern
to improve cooling efficiency and reduce knocking, enabling a
precise ignition-timing setting for optimum power delivery
Shift sensor adopted to establish an ignition map for each gear,
enabling optimum running
Utilizing the space gained by eliminating the kick starter, a new
exhaust features a larger pipe diameter and optimized design at the
branching location for increased power. Previously 31.8mm, the
right and left pipes are now 35mm and 43mm, respectively. In
addition, total tube length (from exhaust port to muffler end) is
up 98mm on the right and 187mm on the left.
Selectable HRC launch control provides a steady stream of torque
for excellent performance on race starts
Updated Standard, Smooth, and Aggressive riding modes enable easy
tuning depending on rider skill or conditions
Chassis/Suspension
Optimized frame for improved traction and cornering feel, as well
as reduced weight
Swingarm is redesigned to be lighter and have appropriate rigidity,
endowing the 2019 CRF450R with great handling and traction
Fork uses revised settings and low-friction oil for improved
performance and handling
Revised shock linkage works with all-new swingarm to provide
optimum performance over bumps
Mimicking the race team's setup, a new, lighter front brake caliper
uses a pair of 30mm and 27mm pistons, versus identical 27mm
pistons, for added braking performance
Updated front brake hose has reduced expansion for more precise
braking
Top triple clamp has two handlebar-clamp locations for moving the
handlebar back and forth by 26mm. With reversible handlebar clamp
enabling an additional 10mm of adjustment from the base position,
there are a total of four different handlebar positions
New black Renthal Fatbar handlebar is positioned 15mm lower than in
2018 for a more active riding position, while also contributing to
light steering feel
Newly shaped footpegs are 20% lighter and shed mud more easily,
giving the rider great feel and confidence in all riding
conditions
Lightweight, compact 1.66 gallon titanium tank keeps weight to a
minimum
Redesigned fork protectors have improved coverage
Black rims deliver a strong presence on and off the track
Minimal lines and gaps in the plastic panels result in a smooth
surface, facilitating riding-position changes
New front number plate design accommodates handlebar in any of the
four available positions
In-mold graphics are durable and resistant to peeling caused by
washing or abrasion
Dunlop Geomax MX3S tires offer excellent grip
