The 2000 CR250R MXer has a completely new frame, swingarm, and a thoroughly redesigned engine.

Features & Benefits

Significant Features

  • All-new second-generation twin-spar aluminum frame and swingarm offer optimal balance of rigidity and strength for lighter, easier handling on widely varying track conditions.
  • Redesigned engine ports, air intake tract and exhaust provide excellent high rpm output, improved low and mid-range power delivery, and more useable power throughout the rev band.
  • Slim new design combines with minimal bodywork to emphasize the beautiful frame and engine. A redesigned seat creates a 10-15mm narrower profile in the seat and tank area, providing greater comfort in competition riding.


  • Liquid-cooled 2-stroke single cylinder engine with 66.4mm x 72.0mm bore & stroke and 8.7:1 compression ratio.
  • Power characteristics now provide smoother low and mid-range power delivery while providing excellent high rpm power output.
  • Larger airbox with 35-percent more volume is located 15mm farther forward providing better low-end response, stronger torque, and improved driveability.
  • 38mm flat-slide Keihen carburetor incorporates a triple-taper needle for precise fuel/air metering and superb throttle response.
  • Carburetor insulator features an internal step that smooths airflow drawn into the engine, improving throttle response.
  • Six-petal reed valve improves throttle response and power delivery. Improved production tolerances enhance reed-valve durability.
  • Reshaped CRV rotary/flap exhaust valve has longer extensions at the side of the flap to better follow the exhaust port shape for increased internal turbulence, improved exhaust scavenging, and responsive acceleration.
  • Sub-exhaust valve port is raised 1mm to improve exhaust transition flow to exhaust valves, providing smoother, more responsive power delivery at low to mid-range rpm.
  • Modified expansion chamber enhances the engine's power output and delivery.
  • 16-bit processor in the ignition CPU produces faster data calculation and more accurate ignition timing for the solid-state 3-D map-type digital ignition.
  • New dual radiators provide 10-percent more surface area and a 8-percent improvement in heat dispersion over the previous single radiator design.
  • Steel water-pump gear for excellent reliability.
  • Durable, smooth-shifting close-ratio five-speed transmission.
  • Primary kickstarting allows starting in any gear.


  • Completely new second-generation frame features smaller, lighter twin-spar aluminum construction with semi-double engine cradle configuration.
  • Extruded aluminum main frame spars are narrowed from 90mm to 80mm while retaining 30mm spar thickness, reducing torsional rigidity 25-percent and increasing lateral rigidity 10-percent to provide an ideal balance of rigidity, strength, compliance and comfort.
  • New chassis design moves frame spars lower for a narrower feel.
  • New forged aluminum steering head replaces extruded piece, providing a compact and extremely durable mount for the frame spars and engine downtube.
  • Semi-double engine cradle features a single, large diameter 45mm x 50mm dual box section downtube. Two rugged box-section rails attach to the base of the downtube and support the engine.
  • Redesigned upper and lower triple clamps increase steering precision.
  • Lightweight, 47mm inverted Showa cartridge fork features 12.4 inches of travel, 16-position rebound damping adjustability and 16-position compression damping adjustability.
  • Inner surface of front fork outer-tubes and rear damper case are molybdenum-coated for low friction.
  • All-new swingarm features a dual-axis, double taper design with a larger, cast aluminum cross-member for 25-percent greater swingarm rigidity.
  • Pro-Link? single-shock rear suspension system features a fully adjustable Showa rear damper and 12.5 inches of wheel travel. Separate low-speed (13 positions) and high-speed (3.5 turns) compression damping adjusters.
  • Rear shock's damper piston diameter is increased from 46mm to 50mm for consistent performance under demanding riding conditions.
  • Redesigned Pro-Link linkage is 3.5 ounces lighter, providing a lower rate in the swingarm's initial travel and a higher rate approaching full compression for a smoother, progressive ride.
  • Linkage mount on frame cross-brace is raised 10mm to minimize ground contact on jump landings and rough terrain.
  • Increased rear axle diameter from 20mm to 25mm and larger diameter bearings
  • provide a significant increase in rigidity to withstand tortuous track conditions.
  • New, compact dual-piston front brake caliper with steel pistons reduces unsprung weight by 2.8 ounces.
  • Front disc brake cover helps protect the large 240mm rotor and caliper from damage.
  • Rear disc brake features low-positioned caliper and thin, large-diameter, 240mm rotor for maximum power and responsiveness.
  • Strong, rigid front wheel features large-diameter front axle and wide wheel-bearing span.
  • Super-light rims, straight-pull spokes and lightweight hubs offer exceptional durability and minimize unsprung weight for optimum suspension action.

Additional Features

  • All new fenders, shrouds and sidecovers emphasize a clean, purposeful design.
  • Reshaped seat with softer foam is positioned closer to the reshaped fuel tank, providing a smooth transition to increase rider comfort and mobility.
  • Handlebar is rubber-mounted to reduce rider fatigue and improve comfort.
  • CR125/250 handlebar holders provide 3 different mounting positions: standard CR250R holder provides neutral position and optional CR125R holder provides _3mm fore or aft position to match rider preference.
  • Removable rear subframe allows easy maintenance.
  • Washable, two-stage foam air filter for optimum engine protection and easy maintenance.
  • Repackable silencer for maximum performance and minimal noise.
  • Lightweight, rugged chain guide and lower chain roller for maximum durability.
  • Comfortable, durable controls and high-quality fasteners.
  • Adjustable front brake lever.
  • Stainless steel clutch cable for long life.
  • Wide, cleated cast stainless steel footpegs are self-cleaning, resist corrosion, provide excellent grip and fold for extra ground clearance.
  • Cleated rear brake pedal and folding shift lever tip.
  • Ownership includes one-year complimentary Membership in the Honda Rider's Club of America. Benefits include discounts, travel benefits, roadside assistance and much more. For HRCA details, call 1-800-847-HRCA.
