Honda XR100 Review: Is It The Right Bike For You?

Looking to get a Honda XR100? Whether you’re looking to buy one or you just want to know as much about it as possible, you’re in the right place!

I’ve had a few of them over the years, so I’m going to show you what this 100cc Honda dirt bike is, how to know if it’s good for you, and then what to expect buying and owning a used one so that you save time and money.

What is the Honda XR100 & who’s it for?

It’s a 100cc air-cooled 4 stroke trail bike with a 5 speed manual transmission and clutch. It’s designed for teens, young adults, women, or any shorter rider that wants to learn how to ride a dirt bike with a clutch.

It is big enough for adults to use as a pit bike, yet has a short enough seat height for a kid (just over 30″).

Its smooth power makes it easy to ride, and has enough torque to do most anything the bike should handle. These are key factors as to why it’s so popular.

XR100R vs XR100 Differences

The difference between the Honda XR100R and the Honda XR100 is Nothing, besides the added letter.

After 1985 XR100R is the actual name designation that Honda gave this dirt bike. Many people just use XR100 to shorten it up and save time when typing it in or saying it out loud.

With that said, the 1984 and earlier XR100 has an older design, which includes the lower performance dual rear shocks. In 1985, Honda officially renamed it the XR100R and went to a single rear spring shock.

When Did Honda Stop Making The XR100?

Technically, the last year of the XR100 was in 2003. However, the CRF100F, which is virtually the same dirt bike, was built until 2016, when Honda transitioned to the CRF125.

The Do-It-All Starter Bike

Why is it one of the best dirt bike to start out on? It’s extremely easy to ride, and has every control you’ll ever use!

Easy kick-start, throttle, brakes, clutch, suspension….What more do you need from a “First-bike”?

The XR100 is easy enough for a kid to kick-start it, so you don’t need the added weight of a battery and starter; although one could come in handy when stalled on a hill.

The engine is very forgiving with its clutch and buttery-smooth power. It’s a lot more difficult to stall this on the trails than a motocross bike.

Even though the newest CRF100F only puts out a measly 6 horsepower, it’s still enough to chug around the property with an adult on the saddle.

Suspension – what to expect

For what it is, suspension on the XR/CRF 100 is pretty versatile. While I don’t recommend racing one in its stock form, it sure can take a beating.

Many adults and bigger kids (me) like to rip around on these bikes; hence why finding a roached XR100 for sale is common.

Why do we do it? Because it’s so fun on a smaller bike that you can just whip around.

All in all, the stock springs are meant for some under 130lbs that trail rides. It will last longer than it should if you jump it, but you risk breaking the frame, handlebars, and possibly more.

Stiffer springs and an aftermarket frame cradle are a must if you’re going to race/jump this bike.

A modified XR100 is a “hoot” to ride for us adults!


The 100cc four-stroke air-cooled engine that powers the Honda XR 100 and CRF 100 has virtually stayed the same over the past few decades (other than the CDI ignition upgrade in ’92).

It may not be up to date with today’s four-stroke motocross bike technology, but why change something that already works, and works well!

The power is very smooth and manageable, and can still get you out of a lot of messes. Due to a heavy flywheel and low gearing, stalling is not an issue on the XR 100.

It has just enough power to give you loads of fun, yet won’t get you or a beginning rider into too much trouble.

This 100cc dirt bike engine is commonly used for sheer pleasure by many adults. It is an excellent starting point because it’s cheap, easy to work on, and has the potential to be a fast little machine.

XR100’s are used to make pit bikes, supermoto, flat-track, and mini motocross for these reasons.


This is where Honda gets its name. The reliability of the Honda XR machines are at the top step. If you keep up on maintenance (which isn’t much), the XR100 will last for years, if not decades, on the stock engine.

Keep oil in it by changing it after about 10-15 hours of use (depending on the riding conditions), keep the air filter clean, and don’t let the gas go bad.

It’s pretty common to see well used XR 100’s from the early-mid 90s with as little as a piston re-ringing or valve adjusting. It’s amazing how long these things will last, especially for how high they rev (no rev-limiter).

Reliability is one of the main reasons adults use this engine for their pit bikes. Even after modifying the engine it can still last a long time.

XR100 vs TTR125

While the TTR125 has slightly more power, the XR100 can still hold its own. I like the ergonomics and handling of the 2001 and newer models. However, none of them have electric start.

So, which is better? The biggest difference is electric start option on the Yamaha.

Both the XR100 and TTR125 have plenty of aftermarket mods available. I’d go with the one that you can find the best deal on in good condition.

You Should Buy An XR/CRF100 If You:

  1. Want cheap fun
  2. Enjoy riding more than maintaining
  3. Want to learn how to ride a motorcycle
  4. Like pit bikes
  5. Trail ride
  6. Like the 4-stroke power curve
  7. Want an easy to ride bike
  8. Want a back-up bike

You Shouldn’t Buy An XR100 If You:

  1. Expect a race bike in stock form
  2. Don’t like having fun

Add a gallon of gas and you’re in for some serious fun…

What’s an XR100 Worth?

You can check bluebook prices, but they generally not be accurate. The best way to determine the value or worth of an XR100 is to check the local market. This goes for any dirt bike, as it’s all about supply and demand.

An XR100 in good shape is generally worth around 900-1200 in the U.S., but it may be hard to find one that cheap if there’s very few of them available. The opposite goes for a surplus of XR100’s.

The second most important factor to its worth is the actual condition of the dirt bike. If you’re going to look at one to potentially buy, make sure you know what to look for so that you don’t get screwed over.

XR100 Mods?

While a stock XR100 is fairly restricted to more skilled riders and weekend warriors, there are endless mods and upgrades you can do to beef up this bike to make it more potent. A pipe and heavy duty suspension upgrade may be all it takes to provide hours and hours of fun.

However, some of us that are more on the edge like to go a step or four further… This can turn into an all-out pit bike build that starts with an XR 100 engine as the power-plant, but uses a modified chassis/suspension from an 85cc 2-stroke motocross bike.

If you want to add even more fun, modifying an XR100 is a great hobby if you enjoying wrenching on things, plus it’ll be faster if you add the right engine and suspension upgrades. Click Here to learn what the top 5 five mods are for the XR100.

5 simple tips for buying a good used XR100

Since you can’t buy one new, you’re going to have to buy one used, and that can be scary. You don’t know what the previous owner has done to the bike, so it may be a piece of junk, but that’s where I can help.

I’m 16 years old and looking for a first bike to learn riding and wondering if this is a good bike to start on?

This is a great bike to start on and learn how to use the clutch! However, if you're taller than 5'6", it might feel a little bit cramped for you. If so, then a CRF150F or XR200 trail bike might fit you better. Thanks for reading, Evan! I'm excited that you want to start out on the right beginner bike!

Is it possible to street modify these bikes? If so how much would that cost?

Kelley Fager

It depends on where you live and what the laws on registering an off-road bike are. In some states, you can get a title and street legalize just about any bike if you meet the requirements. The cost mainly depends on how much you want to spend on each modification. You could probably do it for a few hundred dollars if you're thrifty. Check out this guide on how to convert a dirt bike to a street legal supermoto.
