2007 Honda CRF150R/CRF150R-Expert

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.


Features & Benefits


– Powerful four-stroke 149cc liquid-cooled four-valve Unicam® engine produces impressive power across a wide rpm range for easy-to-control operation.

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

– Compact, lightweight engine assembly weighs only 43.6 pounds.

– Unicam valve train provides the light weight of a compact single-cam drive and the optimum combustion chamber shape for maximum power at all engine rpm.

– Unicam valve train features a carburized single camshaft that directly actuates two 26mm steel intake valves. The steel 22.5mm exhaust valves are actuated by twin, low-friction rocker arms.

– Crankshaft is made of high-strength, low-carbon steel with carburized main journals for maximum durability at sustained high-rpm

– Forged 11.7:1-compression slipper piston and rings are lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.

– Double-carburized connecting rod utilizes a big-end needle bearing for maximum high-rpm performance and durability.

– Nikasil cylinder lining is lightweight and provides cooler operation for extended engine life.

– Press-fitted aluminum spark plug pipe fits between the two exhaust rocker arms, further contributing to compact cylinder-head design.

– 32mm Keihin FCR carburetor features four rollers on the flat slide, resulting in very light throttle effort, smooth operation, crisp throttle response and excellent rideability.

– Carburetor features a throttle position sensor (TPS) that helps maintain a linear throttle response throughout the range.

– 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 potential clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil and permits the use of a smaller oil pump.

– 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 aluminum muffler.

– Dual radiators feature a refined core area for improved heat dissipation compared to conventional dual-radiator design.

– Gear-driven balancer reduces vibration and drives the water pump. A six-disc clutch provides the surface area necessary to handle the engine’s impressive torque, while carefully matched clutch springs provide a light feel at the lever.

– Durable close-ratio five-speed transmission.



– Front and rear suspension settings unique to the CRF®150R deliver ideal bump-absorption characteristics.

– All-new handlebar bend optimizes rider position and comfort.

– Lightweight, high-tensile steel frame with large-diameter frame tubing and cross-member provides excellent turning performance and straight-line tracking.

– Box-section aluminum swingarm is lightweight and rigid.

– Removable subframe is strong and durable.

– 37mm leading-axle inverted Showa cartridge front fork features friction-reducing design to improve compression and rebound control.

– The fork offers adjustable compression and rebound settings.

– Wide-section aluminum top and bottom triple-clamps position fork tubes far apart for good turning and control.

– Tapered-roller steering-head bearings for durability.

– Pro-Link® rear-suspension system features a fully adjustable Showa shock for superb compliance and wheel control.

– Strong, lightweight wheels are durable and minimize unsprung weight.

– Lightweight front and rear disc brakes with high-performance pads offer powerful, precise braking.

– Stout 15mm front and 17mm rear axles incorporate a surface-treatment for added strength and durability.


Additional Features

– Large-capacity airbox and reusable two-stage foam air filter.

– Lightweight plastic body components (radiator shroud, sidecovers, rear fender, seat base, fuel tank, front fender and front number plate) offer a slim, aggressive style.

– Seat-cushion foam 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.

– High-quality Dunlop tires.

– HRC works-type rear-brake system integrates the rear master cylinder and fluid reservoir, eliminating the separate rear master-cylinder reservoir and hose.

– Adjustable front-brake lever and master-cylinder assembly are the same as CR®125R/CR250R components.

– Stainless-steel clutch cable for long life and improved feel and action.

– Works-type handlebar grips add to rider comfort.

– 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 and 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.
