2019 Honda CRF250RX
Based on Honda's
successful 250cc motocrosser, the all-new CRF250RX is specially
designed for closed-course off-road competition. Joining the
CRF450RX in the quest for podiums in series like GNCC and
WORCS, this off-road weapon features all of the same
performance-driven features as the CRF250R, but adds
off-road-specific features like a larger fuel tank, aluminum
sidestand, and 18-inch rear wheel.
Ready for the biggest news the off-road riding community is going
to hear this year? Introducing the all-new Honda
CRF250RX, a high-performance trail/enduro machine built to
exploit all the advantages a 250 has to offer. Bigger Baja bikes
may get all the attention, but 250 riders know where their bikes
really shine: on tight, technical trails that leave those big
open-class riders panting and exhausted, while they use the light
weight and maneuverability to flick through challenging terrain. So
we've equipped the new CRF250RX with the same great engine and
chassis as the CRF250R motocrosser, but added an 18-inch rear
wheel, a bigger fuel tank, special suspension settings, a
sidestand, and more. It's all about giving you the best bike in the
class.
CRF250RX Key Features
Large-capacity, 2.2 gallon resin fuel tank for completing long
closed-course off-road loops
18-inch rear wheel to enable taller tire sidewalls for improved
traction in technical conditions
Forged aluminum sidestand is designed to be lightweight yet
strong
Sealed drive chain to withstand the elements
Suspension with settings dedicated to closed-course off-road
use
Engine/Drivetrain
High-performance, 249cc single-cylinder engine with
dual-overhead-cam design and high rev limit, offering great
performance
Finger rocker arm with Diamond Like Coating (DLC) maximizes valve
lift while retaining a low engine height
Downdraft intake layout produces strong power and enables great
throttle response by reducing resistance, thereby improving
air-charging efficiency
Dual exhaust ports enable ideal air-charging efficiency
Cam profile, which is based on feedback on the CRF250R used by the
Team HRC factory MX2 race team, provides strong off-corner
acceleration
Intake- and exhaust-port geometry provides strong low-rpm engine
power while also maintaining stellar top-end performance
44mm throttle body offers ideal low-rpm intake airflow for strong
corner-exit performance
Honda's piston oil jet with five nozzle holes provides superior
piston-cooling efficiency and reduced knocking, enabling a precise
ignition-timing setting for optimum power delivery
Lightweight AC generator keeps weight to a minimum and minimizes
friction losses
Electric-start standard for easy, fast engine startup
Easily selectable Standard, Smooth, and Aggressive riding modes
enable easy tuning depending on rider preference or course
conditions
Selectable HRC launch control provides a steady stream of torque
for excellent performance on race starts
Exclusive ECU settings for ideal engine performance and rideability
in off-road situations
Chassis/Suspension
Lightweight aluminum frame with tapered main spars provides great
rider feedback
Low center of gravity reduces front-end lift for strong
acceleration
Renthal Fatbar® handlebar reduces steering-system weight, and
flexes for comfort
Top triple clamp features two handlebar-holder locations for moving
the handlebar rearward and forward by 26mm, ensuring rider comfort.
When holder is turned 180 degrees, the handlebar can be moved an
additional 10mm from the base position, resulting in four total
unique handlebar positions
Newly shaped footpegs are 20% lighter and shed mud more easily,
giving the rider great feel and confidence in all riding
conditions
Engine guard allows excellent airflow, boosting engine-cooling
performance
49mm Showa SPG coil-spring fork with dedicated settings for ideal
handling and comfort in technical conditions experienced in
off-road racing
Fork protectors have outstanding coverage for protection in
off-road conditions
Black rims offer strong presence parked in the pits or out on the
trail
Lightweight front-brake caliper uses pistons of different diameters
(30mm and 27mm) for strong braking performance
Front-brake hose resists expansion for precise braking
Smooth bodywork layout eases rider movement
In-mold graphics are durable and resistant to peeling caused by
washing or abrasion
Dunlop Geomax AT81 tires provide optimum feel and traction in
challenging riding conditions
