[QUOTE="onefasthonda, post: 20591, member: 378"] 2000 NEW FOR 2000: All-new second-generation twin-spar aluminum frame and swingarm. 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 with minimal bodywork. A redesigned seat creates a 10-15mm narrower profile in the seat and tank area. ENGINE: Larger airbox with 35-percent more volume is located 15mm farther forward. 38mm flat-slide Keihen (PWK Air Striker) carburetor incorporates a triple-taper needle. Carburetor insulator features an internal step that smoothes airflow drawn into the engine. 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. Modified expansion chamber. 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. CHASSIS / SUSPENSION: 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. 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. 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. 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. Linkage mount on frame cross-brace is raised 10mm to minimize ground contact. Increased rear axle diameter from 20mm to 25mm and larger diameter bearings. New, compact dual-piston front brake caliper with steel pistons reduces unsprung weight by 2.8 ounces. ADDITIONAL FEATURES: All new fenders, shrouds and sidecovers. Reshaped seat with softer foam is positioned closer to the reshaped fuel tank. Handlebar is rubber-mounted. 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. Adjustable front brake lever. SPECIFICATIONS: Model: CR250R Engine Type: 249cc liquid-cooled single-cylinder two-stroke with power-port system Bore and Stroke: 66.4mm x 72mm Compression Ratio: 8.7:1 Induction: Six-petal reed valve Carburetion: 38mm flat-slide Ignition: Solid-state 3-D map-type digital ignition with electronic advance Transmission: Close-ratio five-speed Final Drive: #520 chain; 13T/50T Suspension Front: 47mm inverted Showa cartridge fork with 16-position rebound and 16-position compression damping adjustability; 12.4 inches travel Suspension Rear: Pro-Link Showa single shock with spring preload, 17-position rebound damping adjustability, and compression damping adjustment separated into low-speed (13 positions) and high-speed (3.5 turns); 12.5 inches travel Brakes Front: Single 240mm disc with twin-piston caliper Brakes Rear: Single 240mm disc Tires Front: 80/100-21 Tires Rear: 110/90-19 Wheelbase: 58.5 inches Rake (Caster Angle): 27.73° Trail: 113.8mm (4.48 inches) Seat Height: 37.7 inches Ground Clearance: 13.1 inches Dry Weight: 213.8 pounds Fuel Capacity: 2.0 gallons [/QUOTE]
