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.
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.
Exhaust system uses a lightweight stainless exhaust header and repackable aluminum muffler.
Vertically split crankcases feature a built-in oil pump, reducing weight compared to a conventional design.
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®150R deliver ideal bump-absorption characteristics.
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.
Strong, lightweight wheels are durable and minimize unsprung weight.

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.
