Features & Benefits

New for 2001

• New cylinder port shapes and timing specs provide a smoother and stronger power delivery, and produce lightning-quick acceleration.
• All-new lighter 38mm flat-slide Mikuni TMX carburetor adds both initial throttle crispness and improved throttle response to complement the new engine character.
• New reed-petal stopper shape improves mid-range and high-rpm power delivery.
• New exhaust pipe and muffler design completes the new power delivery package.
• New ignition timing curve is matched to the cylinder port changes to produce maximum power over a wide rpm-range.
• New lightweight drive chain is 3 ounces lighter than the previous design.
• New increased spring rates, with lighter damping forces in both fork and shock.
• New piston in rear shock provides improved shock absorption and consistent damping for excellent riding comfort over a wide range of operating conditions.
• New anodized aluminum brake pistons reduce unsprung weight by 48 grams in the front brake caliper.
• New lightweight steering stem features aluminum top threads and stem nut to reduce weight 2 ounces.
• New handlebar grips add to rider comfort.
• New side panels feature 20 percent wider air intake openings for improved response.
• Optional 20-inch front wheel improves cornering traction and rider comfort.
• Team Honda-inspired colors and graphics.

Engine

• Liquid-cooled two-stroke single-cylinder engine with 66.4mm x 72.0mm bore and stroke and 8.5:1 compression ratio.
• 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.
• Six-petal reed valve improves throttle response and power delivery. Close production tolerances enhance reed-valve durability.
• 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.
• Modified expansion chamber enhances the engine's power output and delivery.
• A 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.
• Dual radiators provide 10 percent more surface area and an 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.

Chassis/Suspension

• Second-generation twin-spar aluminum frame and swingarm offer optimal balance of rigidity and strength for lighter, easier handling on widely varying track conditions.
• Frame features lightweight twin-spar aluminum construction with semi-doublecradle configuration.
• Extruded aluminum main frame spars measuring 80mm x 30mm reduce torsional rigidity 25 percent and increase lateral rigidity 10 percent compared to the first-generation design. The result provides an ideal balance of rigidity, strength, compliance and comfort.
• Chassis design locates frame spars lower for a narrower feel compared to first-generation design.
• Forged aluminum steering head provides a compact and extremely durable mount for the frame spars and engine downtube.
• Semi-double-cradle design 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.
• 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.
• Swingarm design features a dual-axis, double-taper design with a large cast aluminum cross-member.
• 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 50mm for consistent performance under demanding riding conditions.
• Linkage mount on frame cross-brace is raised to minimize ground contact on jump landings and rough terrain.
• Rear axle diameter of 25mm and large-diameter bearings provide significant rigidity to withstand tortuous track conditions.
• Compact dual-piston front brake caliper with aluminum pistons reduces unsprung weight by 48 grams.
• 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

• Slim design combines with minimal bodywork to emphasize the beautiful frame and engine. Seat design creates a narrow profile in the seat and tank area, providing excellent comfort in competition riding.
• Fenders, shrouds and sidecovers emphasize a clean, purposeful design.
• Seat cushion uses soft foam and is positioned close to the fuel tank, providing a smooth transition to increase rider mobility and comfort.
• 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.
