2020 Honda CRF150R Features and Benefits

Posted on May 7, 2019 by The Dirt Bike Guy.

Today Honda announced information and specs regarding the 2020 CRF150R and CRF150R Big Wheel. Honda's smallest motocrosser delivers smooth, ample torque across the rev range thanks to its Unicam four-stroke engine—unique in the mini MX world. Showa suspension components include a rear shock working through a Pro-Link rear suspension system, and a 37mm inverted fork. The CRF150R is offered in both standard and Big Wheel versions, the latter featuring larger wheels, a taller seat height, and more rear suspension travel to better suit larger riders.

Engine/Drivetrain

2020 Honda CRF150R Big Wheel
  • 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
