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.



  • 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.

2018 Honda CRF450RX


  • 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.

  • 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.
