Introducing the 2021 Honda CRF150R Expert Big Wheel…

Competition teaches lessons at every age. Determination. Discipline. Self confidence. Responsibility. But to learn about winning, you need a motorcycle you can win on. And that’s where the Honda CRF150R comes in. Competition ready, it’s tailor-made for younger champions. With a single-cylinder Unicam® engine that packs a punch, they’ll have every advantage, right out of the gate. And for taller riders there’s the CRF150R Expert, with bigger wheels, a longer swingarm and higher seat. These two bikes give them what they need on the track—it’s your job to coach them on their podium speech.



2021 Honda CRF150R Expert Big Wheel Totalmotorcycle.com Key Features

Bigger wheels and higher seat

Standard Features

  • 149cc liquid-cooled single-cylinder four-stroke Unicam® engine
  • Track-designed chassis
  • Pro-Link® rear suspension
  • Front disc brake
  • Strong, lightweight wheels
  • “Direct push” accelerator pump
  • Designed for smaller racers


  • 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

  • Exhaust system uses a lightweight stainless-steel header and re-packable aluminum muffler
  • Durable close-ratio five-speed transmission\


  • 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
  • Stout 15 mm front and 17 mm rear axles incorporate a surface-treatment for added strength and durability

2021 Honda CRF150R Expert Big Wheel Totalmotorcycle.com Features and Benefits

Excellent mass centralization
“Ultra-high RPM, 149 cc engine is one of the most advanced in the sport; its unique 4-valve, Unicam design gives it very compact dimensions and excellent mass centralization for effortless direction changes on the ground or altitude changes in the air. Rail it or whip it with confidence.”

Power when you want it
Short-skirted piston and light flywheel mean the CRF’s willing engine builds revs very quickly—no waiting for the power to “hit”.

Consistent engine operating temperature
“Liquid cooling and a Nikasil cylinder liner help to extend engine life. The cooling system’s lightweight aluminum radiator reduces weight to help ensure consistent engine operating temperature no matter how hard you push.”

More immediate throttle
Flat-slide, FCR 32 mm carburetor is fitted with an accelerator pump for more immediate throttle response. Go ahead, use the 4-stroke advantage to grab the holeshot.

Less shifting more enjoyment
Broad 4-stroke power characteristics allow the CRF150RB to use a five-speed gearbox for less shifting so you can concentrate on your riding.

Easy start from hot or cold
Although the 4-stroke engine is hard to stall, it’s nice to know that an automatic decompression system makes starting easy, hot or cold.

Maximum power output
Maintenance-free digital CD ignition system includes a throttle angle sensor so it can tailor the ignition curve to provide maximum power output whenever you grab that throttle.

Increased durability & maximum control
Heavy-duty clutch is fitted with tough friction plates for increased durability but retains a light pull at the lever giving you maximum control.

Excellent performance
Lightweight high-tensile steel frame with large-diameter tubing provides excellent turning performance and keeps you tracking straight through the whoops.

Riding comfort & traction
37 mm, inverted, Showa cartridge front fork features adjustable compression and rebound settings. The fork’s low-friction design will be especially appreciated when it’s helping the front wheel to follow small surface irregularities without breaking traction.

Improved turning precision
Wide-section aluminum top and bottom triple-clamps hold the inverted forks rigidly and position the fork tubes far apart giving you improved turning precision and control.

Comfort on any terrain
Pro-Link® rear suspension system features a fully adjustable Showa shock that effectively soaks up whatever the track or trail can throw at it.

Precise control over any terrain
“Lightweight wheels and hubs help to reduce un-sprung weight allowing the wheels to effectively follow uneven terrain. The strong and rigid, but lightweight, box-section aluminum swingarm further enhances rear wheel tracking offering precise control whether you’re braking over stutter bumps or root infested trails.”

Easy braking in any condition
“Lightweight front and rear disc brakes with high-performance pads offer powerful, easy to modulate braking even when you’re riding in some of the worst conditions.”

Consistent power
Large-capacity airbox and reusable two-stage foam air filter means power won’t drop off during long, dusty rides.

Stay comfortable & stay put
Slim, well-padded seat is comfortable and allows maximum movement. Non-slip seat cover gives you excellent control.

Personalized comfort
Fully adjustable, high-quality controls include comfortable grips, dogleg levers, side-pull throttle and a folding shift lever. Cleated, folding, self-cleaning footpegs offering excellent grip complete the impressive collection of thoughtful touches.
