2007 Honda CR125R- Features & Benefits

Honda's two-stroke racer sets the standard for quality and performance with its class-leading technology, and has a reputation for being easy to ride for novices and professionals alike.

Engine/Drivetrain

  • Crankcase intake tract and six-petal reed valve for more efficient airflow and improved drivability.
  • Reed valve features thick reed plates for better off-idle response.
  • Piston features single keystone piston ring for improved sealing.
  • 28mm radiator core improves cooling capacity.
  • Shift fork shaft, shift forks and shift drum designed for precise shifting performance.
  • Liquid-cooled two-stroke single-cylinder engine with 54mm x 54.5mm bore and stroke and 8.6:1 compression ratio.
  • Nikasil-plated cylinder reduces friction and heat to improve overall performance.
  • Piston ring groove is anodized for added durability.
  • Air-intake boot is shaped for direct airflow and better low-speed engine performance.
  • Foam gasket between airbox and air boot for better sealing and air flow management.
  • 38mm Mikuni TMX carburetor with throttle position sensor (TPS).
  • Carbon-fiber six-petal reed valve with sub reeds is designed for better top-end and low-end power.
  • Exhaust port is shaped to improve top-end and over-rev power delivery.
  • RC-style exhaust valve features an NSR road-racing-inspired rotary flap design with governor control that provides a smooth power transition between low- and mid-range engine speeds. Exhaust valve flap features more overlap to minimize exhaust gas leakage between flap and cylinder.
  • Exhaust header is designed to improve low-end and over-rev power delivery. The expansion chamber design enhances the engine's power output and delivery.
  • A four-pole ACG design produces a high-voltage spark throughout the rpm range with low magnetic drag, thus permitting a freer-revving engine.
  • A 16-bit processor in the ignition CPU produces immediate data calculation and extremely accurate ignition timing for the digital ignition.
  • Eight clutch plates provide significant surface area to handle the engine's torque. Clutch springs provide a light feel at the lever.
  • Dual radiators permit forward engine placement and provide significant cooling capacity.
  • Steel water-pump gear and steel kickstarter-shaft collar enhance reliability.
  • Primary kickstarting system allows starting in any gear.

Chassis/Suspension

  • Swingarm features a dual-axis, double-taper design with a large cast-aluminum cross member that is lighter weight and stronger.
  • CR®125R's third-generation twin-spar aluminum frame features taller swingarm pivot plates and thinner frame spars to create a narrower overall frame cross-section, and is also lighter than the second-generation frame.
  • Semi-double-cradle design features a single, large-diameter tapered downtube. Two rugged box-section rails attach to the base of the downtube and support the engine. A forged-aluminum steering head provides a compact and extremely durable mount for the frame spars and engine downtube.
  • Optional 20-inch front wheel improves cornering traction and rider comfort.
  • Rear hub design maximizes strength and lightness.
  • Rear axle diameter of 25mm and large-diameter bearings provide significant rigidity to withstand torturous track conditions.
  • Inverted Kayaba fork features a cartridge design that separates air and oil for reduced contamination and more consistent fork action. Inner surface of fork's outer tubes is honed to retain a thin coating of lubricating oil to reduce friction with fork bushings.
  • Pro-Link® single-shock rear suspension system features a fully adjustable Kayaba rear shock with 12.5 inches of travel, separate low-speed (18 positions) and high-speed (two turns) compression damping adjusters, and 30-position rebound damping. The adjusters are located together in a concentric fashion, with a screw inside a nut.
  • Compact twin-piston front brake caliper, anodized aluminum brake pistons and lightweight front brake disc reduce unsprung weight for improved turning and handling.
  • Large 240mm front and rear brake rotors to provide optimum braking control.

Additional Features

  • Seat follows the shape of the fuel tank, providing a smooth transition to increase rider mobility and comfort.
  • "Non-slip" seat cover for increased rider control.
  • Wide, cleated stainless steel footpegs are improved for self-cleaning and corrosion resistance, and provide excellent grip and fold for extra ground clearance.
  • Cleated rear brake pedal, shift lever and folding shift-lever tip are made of lightweight aluminum.
  • Adjustable front brake lever for optimum control.
  • Quick-adjust clutch perch.
  • Aluminum Renthal 971 bend handlebar is rubber-mounted to reduce rider fatigue and improve comfort.
  • CR handlebar holders provide three different mounting positions: Standard CR125R holder provides a 3mm rearward set and can be rotated 180o to position handlebar 6mm forward. Optional holders (CR250R type) provide neutral position to match rider preference.
  • Works-type handlebar grips add to rider comfort.
  • Front disc brake cover helps protect rotor and caliper from damage.
  • Removable rear subframe allows easy maintenance.
  • Dunlop D742 front and D756 rear tires for optimum traction and cornering.
  • Washable, two-stage foam air filter for optimal engine protection and easy maintenance.
  • Repackable silencer for maximum performance and minimal noise.
  • Stainless steel clutch cable for long life.
  • Purchase of a new, previously unregistered Honda unit by an individual retail user in the United States qualifies the owner for a one-year complimentary membership in the Honda Rider's Club of America™ (HRCA®). Benefits include online access to the Honda Common Service Manual, six issues of the bimonthly Honda Red Rider™ magazine, travel discounts, trip routing, MSF reimbursement, plus access to the HRCA Web site (www.hrca.honda.com). Look for the HRCA support team at select off-road events across the country. For details on the HRCA, dealers should call (310) 783-3958, 8:30 a.m. to 5 p.m. Pacific Time.
