Younger racers may be smaller in stature, but that doesn’t mean they can’t have a giant-sized heart for racing—and winning. So for these younger racers, Honda designed the CRF150RB as an integral part of the CRF® racing lineup.
 
ENGINE/DRIVETRAIN
	
Liquid-cooled 149cc,4-stroke engine offers unrivalled performance and ease of use.
	
Lightweight, compact, internal auto decompression and handlebar-mounted hot-start system provide easy starting, hot or cold
	
Crankshaft is made of high-strength, low-carbon steel with carburised 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-carburised connecting rod utilizes a big-end needle bearing for maximum high-rpm performance and durability
	
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
	
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®150RB 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
	
Swingarm is lightweight and rigid, re-designed for 2018 for added durability
	
Removable subframe is strong and durable
	
37mm leading-axle inverted Showa cartridge front fork features friction-reducing design to improve compression and rebound control
 
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
	
HRC works-type rear-brake system integrates the rear master cylinder and fluid reservoir, eliminating the separate rear master-cylinder reservoir and hose
