2006 Honda CR125R


The CR125R shares a lot with its CR250 big brother: multiple championships, state-of-the-art tech and, best of all, the knowledge that it has no equals when it comes to 125cc two-strokes. Could it be the mind-boggling power? The super-light weight? The tack-sharp handling? Or maybe all of the above? Why not throw your leg over one-and then decide for yourself.

Engine/Drivetrain

- Crankcase intake tract and six-petal reed valve for more efficient air flow and improved drivability.
- Reed valve features thicker 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 air flow 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. Redesigned 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(R)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(R) 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 180 degrees 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.
- Ownership includes one-year complimentary membership for an individual in the Honda Rider’s Club of America(TM) (HRCA(R)). Benefits include: discounts, travel benefits, roadside assistance, one year of Honda Red Rider(TM) magazine, access to HRCA Clubhouse Web site (www.hrca.honda.com) and access online to Honda Common Service Manual. For HRCA details, call 1-800-847-HRCA.

Cr125 probably go around 70 mph

So everybody is aware, no dirtbike is going to go faster than 75mph... They are meant for off road terrain and hitting jumps.

What is the top speed of the cr125?

how much would it cost brand new?

what is the top speed for the CR125R.
