Most Important & Common Want-to-Know Information about the CRF150R

CRF150R Horsepower

As dirt bike riders, we have to know how fast our bikes go and how much power they have. Race bikes and motocross bikes, like the Honda CRF150R, make us want to know even more.

The CRF150R horsepower is about 24 hp. (this is about 10 horsepower less than the YZ 125).

Check out how this horsepower translates into CRF150R top speed.

Honda CRF150R Carburetor or Fuel Injection

Truthfully, I’m a bit surprised, but Honda still uses a carburetor on the CRF150R instead of fuel injection.

Why does this surprise me?

Because Honda released its pit bike, the CRF110, with fuel injection before this motocross bike.

Seems odd to me.

I guess Honda tries to justify it by saying that the bike uses a “‘direct push’ accelerator pump which gives you better, more immediate throttle response.”

Having a carburetor isn’t necessarily bad, it’s just surprising that Honda would include it in a pit bike before a race bike.

If you are having trouble with your bike running properly due to carburetor issues, be sure to read our lean bog vs rich bog guide.

Electric Start or Kick

Again, kind of surprising, like the carburetor, the Honda CRF150R does not have electric start.

Honda has added electric start to many F model bikes, including the CRF150F, but not the R model.

CRF150R Oil

Honda recommends the CRF150R engine oil to be 10W-30. The CRF150R engine oil capacity is 0.59 quarts for just changing the oil. If you also change the oil filter, the oil capacity is 0.62 quarts. If you disassemble the engine, the oil capacity is then 0.74 quarts.

The CRF150R transmission oil is recommended to also be 10W-30. The transmission oil capacity is 0.60 after draining and 0.69 quarts after disassembling the engine.

Wheels and Tires

The Honda CRF150R comes stock with a 17-inch front wheel and a 14-inch rear wheel. The front tire dimensions are 70/100-17 and the rear tire dimensions are 90/100-14. The bike comes stock with Dunlop MX51 tires front and rear.

It’s important to note that the above information is for the R model NOT the Expert model. The Expert model’s information is below.

The CRF150R Expert model comes stock with a 19-inch front wheel and a 16-inch rear wheel. The front tire dimensions are 70/100-19 and the rear tire dimensions are 90/100-16 This model also comes stock with Dunlop MX51 tires front and rear.

The CRF150R and the CRF150R Expert are essentially the same bike, the only major difference is the wheel size mentioned above.

CRF150R Weight

A CRF150R weighs about 185 pounds wet (which means including all fuel and fluids).


In the front, the bike comes stock with 37mm leading-axle inverted Show cartridge forks that have 10.8 inches of travel and allow you to adjust rebound and compression.

The rear shock is a Pro-Link Showa shock that has 10.7 inches of travel and allows you to adjust rebound and compression as well.

Honda CRF150R Overview

The Honda CRF150R isn’t all that popular of a race bike at major dirt bike races, but it is still Honda’s sickest mini dirt bike and can be competitive in the right class with the right rider.

Although it is sometimes underpowered at motocross races, it still has enough power to make it not the best bike for beginners. The manual clutch and overall motocross feel to the bike can make it difficult for young, or beginner, riders.

That said, it is a Honda, meaning it’s a very reliable, high-quality machine. Honda says they’ve taken a lot of the technology advancements from the CRF450R motor and used that in the R&D of the CRF150R motor.
