(Press Release) Raced by Amsoil Honda hotshot Hunter Yoder on the amateur national circuit, Honda's smallest motocross machine is powered by a Unicam® four-stroke engine that offers a spread of ample, useable power and torque across the rev range. Suspension duties are handled by Showa®, with a 37mm inverted fork and Pro-Link® rear link system. In addition to the standard version, Honda offers the CRF150RB, which features larger wheels, a taller seat, a longer swingarm, and more rear-suspension travel.
Engine/Drivetrain
| High-performance Unicam cylinder-head design |
| Compact, lightweight engine assembly weighs only 43.6 pounds |
| Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a supply of cool 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 |
| Cylinder head, piston, camshaft, and carburetor provide power, torque, and rideability throughout the powerband |
| Lightweight, compact, internal auto decompression and handlebar-mounted hot-start system provide easy starting, hot or cold |
| 32mm Keihin FCR carburetor with an accelerator-pump circuit provides accurate fuel metering, resulting in crisp throttle response and good rideability throughout the powerband |
| Suspension settings provide good action through even the toughest of track conditions |
| Exhaust system uses a lightweight stainless-steel header and re-packable aluminum muffler |
| Durable close-ratio five-speed transmission |
Chassis/Suspension
| Front and rear suspension settings unique to the CRF150R deliver ideal bump-absorption characteristics |
| Lightweight, high-tensile steel frame with large-diameter frame tubing and cross-member provides excellent turning performance and straight-line tracking |
| 37mm leading-axle inverted Showa cartridge fork features friction-reducing design to improve compression and rebound control |
| Pro-Link rear suspension |
| 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 |
| Large-capacity airbox and reusable two-stage foam air filter |
| Lightweight plastic body components (radiator shroud, side covers, rear fender, seat base, fuel tank, front fender, and front number plate) offer a slim, aggressive style |
| 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 |
