HONDA OFFICIAL RELEASE: 2018 CRF450RX OFF-ROAD MODEL

Honda just released the 2018 version of the CRF450RX off-road 450. The most interesting change is that it lost the kickstart lever and should be slightly lighter as a result. Here’s the official press release.

 

Engine/Drivetrain

• Smoother ignition map than CRF450R for better performance in low-traction situations.
• Downdraft intake layout increases power by reducing resistance, improving air-charging efficiency.
• Combustion chamber with high compression ratio, narrow valve angle for efficiency.
• Use of finger rocker arm allows high valve lift while retaining compact Unicam layout.
• Coils on valve springs have oval cross-sections to allow low engine height.
• Port layout with straight flow for efficiency.
• Diamond-like carbon (DLC) on piston pin, rocker arm minimizes friction, increases durability.
• Dual muffler with gradual pipe bends for smooth exhaust flow.
• Standard electric start, with lithium ion battery.

Suggested Retail Price : $ 9,249

Chassis/Suspension

• Compared to CRF450R, suspension settings are more appropriate for technical off-road conditions.
• With a 2.25 gallon capacity, the plastic fuel tank is larger than that of the CRF450R for increased range off-road.
• Forged-aluminum side stand is standard to allow trailside parking.
• Off-road-focused, durable Dunlop Geomax AT81 tires.
• One-tooth larger rear sprocket than CRF450R, for better performance in tight woods conditions.
• Different cylinder hanger than CRF450R, for comfort in technical off-road conditions.
• Chassis layout maximizes traction through concentration of mass, low center of gravity.
• New, lighter sixth-generation aluminum twin-spar frame with revised geometry; allows improved cornering performance through reduction of torsional stiffness (lateral stiffness is unchanged).
• Lightweight swingarm assembly is stiff vertically and laterally.
• Rear-suspension location lowers center of gravity.
• Lightweight aluminum rear subframe with extruded gussets.
• Coil-spring 49mm Showa fork.
• Plastic bodywork with smooth layout and film-insert graphics for appearance and durability.
• Front fender shape allows efficient air path to radiator.

• Consult owner’s manual for optional racing parts
• Meets current CARB and EPA emissions standards
• Specifications subject to change
