Honda CRF150R Review – Who This Bike Is Really For

Trying to figure out if the Honda CRF150R is the right dirt bike for you? I’ve owned 2 of them, so I’d like to share my personal review about this bike so that you can make a better buying decision, or simply get to know it better if you already have one. 

CRF150R vs CRF150RB Differences?

They are almost the same bike, except the wheel sizes, wheelbase and slight suspension difference. 

The CRF150R is the small wheel version with 17/14″ wheel and tire size, while the CRF150RB is the larger and longer big wheel (AKA “Expert”) with 19/16″ wheel size and slightly stiffer suspension valving. 

Who Is The CRF150R For?

The CRF150R is a motocross bike that’s not to be confused with the CRF150F trail bike. While the 150R is a kids bike, it’s a high performance race bike.

Age Range

The CRF 150R is built for racing in the 85cc/Supermini class, which is for kids age 12-16 years old. It’s currently the only kids motocross bike from Honda. The small wheel (standard model) is for a 12 year old, and the big wheel (expert model) is for ages 14-16 years old.

However, your kid’s age shouldn’t be the only factor. They may be too small or big for it.

Is a Honda CRF150R for adults?

With that said, there’s plenty of adults that ride the CRF150RB, including myself! Follow the mods at the end to make it more comfortable for you.

Can a CRF150R be trail ridden?

Yes, that’s why I bought a CRF150R in the past. However, it’s not a very good trail bike in stock form on single track trails. It stalls easily, has rather harsh suspension, and is just a little too snappy.

Below is a video of me riding my backyard trails. It takes a lot more energy to ride fast than my CRF230F because of the reasons I just gave. With that said, if you could tone it down, make it a little plusher and easier to ride, then the CRF150R could be a good trail bike for adults or teens.

Rider Size

The small wheel CRF150R has a seat height of 32.8”. It will fit you if you’re between 4’10 and 5’2” (147-157cm).

The big wheel CRF150RB has a seat height of 34.1” It will fit if you’re between 5’0” and 5’6” (152-168cm).

With that said, your inseam length plays a big role in how you fit it as well.

The Bottom Line For Deciding If The CRF150R/B Is Right For You

Whether you or your kid is the right size for the 150R or 150RB, skill level and the type of riding should be the biggest determining factor.

CRF150R Cons:

This is a motocross race dirt bike. This means its disadvantages are:

  • Harder to kick start
  • Doesn’t have much low-end power (bad for beginners)
  • The power is abrupt and less predictable than a trail bike
  • Suspension is for 80-100lb rider, but is harsh for trail riding
  • It’s easy to stall (bad for beginners)
  • Small gas tank (bad for long trail rides)

CRF150R Pros:

However, where the CRF150R is good is:

  • No mixing gas (It’s a 4 stroke engine)
  • It’s lightweight for a 4 stroke
  • It has more torque than an 85cc 2 stroke (YZ85/KX85/CR85)
  • It can be a fun trail bike for an adult with some mods

Is The CRF150R Reliable?

Reliability was originally seen as an issue, but in actuality, that’s not necessarily true. Yes, the CRF150R is not as reliable as its CRF150F cousin, but that’s because it’s a race bike that requires you to ride it harder. The more RPM, the quicker the engine will wear out; it’s simple science.

With that said, you’re not going to have to adjust the valves every 5 hours like some people may have said on forums. If you’re trail riding the CRF150R or are easy on the throttle and properly maintain it (oil and filter changes), it’s going to be pretty reliable. You might get 50 or 100+ hours on the engine before needing a rebuild.

Does It Have A Weight Limit?

There isn’t an actual weight limit, but the CRF150R/B is built for a rider that weighs about 80-120lb. 

Can you ride it if you weigh 150lbs or more? Yes, but the suspension is too soft for aggressive riding and will bottom out.

If you’re an adult and want to ride the CRF150R then I highly suggest getting stiffer springs and possibly re-valving the suspension. I cover that in the mods section at the bottom of this article.

Honda CRF150R Year Changes

There haven’t been too many big changes made to the CRF150R or CRF150RB since the year it was first made in 2007.

The noticeable changes made are:

  • 2008: Carburetor needle changed for easier jetting tuning
  • 2012: New cylinder head, piston, camshaft, and accelerator pump circuit updates

CRF150R Year Identification

So, how do you best identify which year model you have or if you’re going to look at a used one for sale? The graphics are specific to each year, but the best way is by reading the VIN. The VIN is on the right side of the steering stem frame. 

The year is determined by the 10th digit in the 17 digit VIN. A “7” would means it’s a 2007, and a “B” means it’s a 2011.

CRF150R Problems?

Valves and top-ends were thought to be a problem in the beginning, but that’s mainly due to mis-use or lack of knowledge. The CRF150R has stainless steel valves, which tend to last longer than titanium valves. This means they’re more reliable and will cause less issues long term.

The biggest problems that I read about from CRF150R owners is when they don’t ride it enough or do not properly maintain it.

When you leave your dirt bike sit, start going bad within months or weeks!

Your CRF150R may have these issues if you let it sit for a few months with pump gas:

  • Hanging idle
  • Hard to start
  • Idle adjustment/screw/problems

It may not even start when you take it out the next time to ride. You may need to do proper carburetor cleaning to fix it.

Maintenance Schedule

Oil changes and cleaning the air filter are the most important maintenance tasks. A schedule or every 10-15 hours for the oil and whenever the filter is dirty is a good starting point. Remember that the CRF150R/B has separate compartments for the engine oil and transmission oil. Meaning you have to drain and fill two different spots.

Valve adjustment

The more you race and ride at high RPM, the more often you should check the valve clearance. You might not have to adjust the valves on your CRF150R every 10-20 hours. It may go 50 or 100+ hours if you’re conservative and properly maintain it.

Used Price

It really depends on your local market. A CRF150R in poor condition may be as cheap as $1200, but a clean bike that’s only a year old might be $4500.

The most common factors for the value of a used CRF150R dirt bike are:

  • What the current market is
  • The overall condition
  • What’s been done to the bike

Best Mods & Upgrades

Whether you’re just looking for more power to race motocross or are an adult that wants to trail ride, there’s quite a few mods available for the Honda CRF150R.

Some of the best mods to upgrade your CRF150R are:

  • Jetting
  • Suspension

Jetting the carb will make it start easier, run smoother, and stall less often.
