2021 Honda CRF150R Totalmotorcycle.com Key Features
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
- 32 mm 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
- 37 mm 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
