Torrance, Calif. 09/06/2006 --
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.
* Powerful four-stroke 149cc liquid-cooled four-valve Unicam(R) 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
operation.
* 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.
Chassis/Suspension
* Front and rear suspension settings unique to the CRF(R)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(R) 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(R)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(R) (HRCA(R)). Benefits include online access to the Honda Common Service Manual, six issues of the bimonthly Honda Red Rider(TM); 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.
