2012 CRF450X Features and Benefits

The CRF450X has won the world-renowned and ultra-rugged Baja 1000 and Baja 500 races multiple times—enough to rightfully earn its reputation as the King of Baja. But even if you’re planning a weekend of relaxed trail riding rather than aiming for a prestigious off-road racing victory, the CRF450X offers equally impressive credentials for a weekend of fun rides.

New for 2012

  • Bold new graphics.

Unique Features

  • Electric-start system for easy starting in all conditions.
  • Gas-tank capacity is 1.9 gallons, including 0.4-gallon reserve.
  • USDA-qualified muffler/spark arrester.
  • Powerful 35-watt halogen headlight features an innovative lens for a wide range of illumination.
  • Integrated LED taillight in rear fender.
  • Easy-access air filter.
  • Suspension tuned for competitive off-road riding needs.
  • 18-inch rear wheel for greater flat-tire protection.

Engine/Drivetrain

  • Powerful four-stroke 449cc liquid-cooled four-valve Unicam® engine is designed to produce power across a wide rpm-band for easy-to-control operation.
  • Forged 12.0:1-compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
  • 40mm Keihin FCR-type carburetor features four rollers on the flat slide, resulting in light throttle effort, smooth operation, crisp throttle response and excellent rideability.
  • Carburetor features a Throttle Position Sensor (TPS) to help maintain linear throttle response throughout the rpm range.
  • Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil and permits the use of a smaller oil pump.
  • Exhaust system uses a lightweight stainless-steel exhaust header and muffler equipped with USDA-qualified spark arrester.
  • T-ring-sealed chain is approximately 1.6mm narrower and is stronger compared with conventional chains.
  • Durable five-speed wide-ratio transmission.

Chassis/Suspension

  • Fourth-generation Twin-Spar Aluminum Frame with forged-aluminum steering head.
  • 18-inch rear wheel features same lightweight rear hub and HRC works-type lightweight aluminum spoke nipples as used on the CRF250R.
  • Front wheel features large-diameter front axle and wide wheel-bearing span for excellent rigidity.
  • Rear-axle diameter of 25mm and large-diameter bearings provide optimum rigidity to withstand torturous off-road conditions.
  • Large 50mm-diameter rear shock damper piston for consistent performance under demanding riding conditions.
  • HRC works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating the need for a separate reservoir and hose assembly.

Additional Features

  • Aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort.
  • Handlebar holders provide two different mounting positions to match rider preference.
  • Front disc brake cover helps protect rotor and caliper from damage.
  • Washable, two-stage foam air filter for optimal engine protection and easy maintenance.
  • Honda Racing-inspired colors and graphics.
