In keeping with the revolutionary CRF450R and CRF250R, Honda's new CRF150R and CRF150R-Expert four-stroke motocross machines are destined to redefine the small-displacement motocross category.

The CRF150RB's powerful four-stroke 149cc liquid-cooled four-valve Unicam® engine produces impressive power across a wide rpm range for easy-to-control operation.

Its lightweight, compact, internal auto decompression and handlebar-mounted hot-start system provide easy starting, hot or cold.

Features

• Press-fitted aluminium spark plug pipe fits between the two exhaust rocker arms, further contributing to compact cylinder-head design.
• Vertically split crankcases feature a built-in oil pump, reducing weight compared to a conventional design.
• Exhaust system uses a lightweight stainless exhaust header and repackable aluminium muffler.
• Dual radiators feature a refined core area for improved heat dissipation compared to conventional dual-radiator design.
• Lightweight front and rear disc brakes with high-performance pads offer powerful, precise braking.

Honda's CRF250R is a thoroughbred performer it smokes the competition right out of the box.

The brilliant future of motocross arrives in the aggressive form of the high-flying CRF250R. With improved engine performance and a developed, mass centralised dual silencer exhaust system contributing to sharper power delivery and smoother, more responsive handling, the new CRF250R provides a potent blend of quick-revving, race-bred 4-stroke performance that dominates the motocross circuit's tight berms and big air jumps with confident ease.

The CRF's innovative, liquid-cooled 4-valve Unicam engine pumps out a wide band of useable power with a strong thrust of low-end acceleration that leaps out of corners. And its rugged, lightweight aluminium frame and fully optimised suspension systems provide amazing control that smokes the competition right out of the box. Racing never fails to improve the breed, and the CRF250R is a thoroughbred performer with the gold to prove it.

Features

• New camshaft and cylinder-head porting improve power output above 8000 rpm.
• New intake valve springs match new camshaft.
• New crankcase venting for improved engine power.
• New exhaust header works in conjunction with new camshaft.
• New carburetor features new-styled accelerator pump and linkage for improved throttle response.

The choice of motocross, off-road and Supermoto riders everywhere, Honda's championship-winning CRF450R receives a host of refinements in 2006 sure to extend its dominance.

The CRF450R has a 41mm FCR-type carburettor features four rollers on the flat slide, resulting in very light throttle effort, smooth operation, crisp throttle response and excellent rideability. Bottom of float chamber is designed to allow more fuel to pass to the main jet.

Also, an  8-bit digital CPU incorporates the capacitive discharge ignition (CDI), producing immediate data calculation and extremely accurate ignition for maximum performance.

The CRF450R has a Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination to the engine oil and reduces the amount of circulating oil and the required size of the oil pump.

Features

• New larger 41mm Keihin FCR carby.
• New smaller exhaust valve for improved flow and smoother power delivery.
• Engine decompression system is lighter and more compact.
• New link-type front brake master cylinder improves front braking power by 15 percent.
• New subframe allows the muffler to be mounted farther forward for better mass-centralisation.
