What is a Honda Monkey?

The Honda Monkey is a small, iconic motorcycle that has been in production by Honda in various forms since 1961, the first year made.

These small 125 motorcycles have a unique look and style, making them popular for a wide range of enthusiests. With their chunky tires, upright seating position, and simple design, these are also a good little street-legal motorcycle for learning how to ride on.

Over the years, the design has evolved, but it has always retained its distinctive retro and playful look.

The Honda Monkey motorcycle is powered by a 124cc air-cooled single-cylinder 4-stroke engine.

Overview:

Type: Street-legal mini-moto, 4-stroke
Stree-legal: Yes
Rider’s age: Adult
Rider’s height: 5’4-6′
Engiene size: 125cc

Popular features:

• Fuel injection
• Five-speed transmission
• High-rise handlebars
• Disc brakes with front-wheel ABS
• Low 30.6-inch seat height
• Electric starter

Who Should Buy

The Honda Monkey, given its unique size, design, and characteristics, is best suited for certain types of riders and specific use cases. Obviously, this isn’t going to be your go-to motocross or cross-country dirt bike. However, if you’re looking for a short distance commuter, this thing is pretty cool.

Here are scenarios for those who might want to buy one:

• Beginner Riders
  Due to its small size and manageable power, the Honda Monkey is a good choice for those new to motorcycling. Its approachable nature allows beginners to gain confidence before moving on to larger motorcycles.
• Urban Commuters
  In congested cities, the Monkey’s compact size and nimbleness make it an excellent tool for short-distance commuting. Its ability to weave through traffic and park in tight spots is a significant advantage.
• Enthusiasts and Collectors
  Given its iconic status and history, many motorcycle enthusiasts purchase the Monkey for its nostalgia factor. Some might even buy it as a collector’s item, especially the older, vintage models.
• Weekend Fun
  Some seasoned riders purchase the Monkey as a secondary bike for leisurely weekend rides, especially if they’re looking for something light and fun.
• RV Travelers and Campers
  Due to its lightweight and compact size, the Monkey is popular among those with recreational vehicles (RVs) or campers. It can be easily transported and provides a convenient mode of transportation when the RV is parked.
• Younger Riders
  While not exclusively a kids’ bike, its small stature can make it suitable for responsible teenagers.
• Off-Path Adventures
  Although it’s not a dedicated off-road bike, the Monkey’s chunky tires and low weight make it somewhat capable of light trail riding or beach cruising at the dunes.
• Those with Physical Limitations
  Riders who might have difficulty handling larger or heavier bikes due to age, physical constraints, or other reasons might find the Monkey more comfortable and manageable.

Who Should Not Buy

However, there are also some situations where the Monkey might not be the best choice. Here are some reasons NOT to buy a Monkey:

1. Long-Distance Touring
   Given its small engine and size, the Monkey isn’t designed for extended highway journeys or touring.
2. High-Speed Highways
   The Monkey’s top speed and stability aren’t suitable for high-speed highway travel, especially alongside much larger vehicles.
3. Carrying Cargo or a Passenger
   Its small frame and engine mean it’s not ideal for carrying heavy loads or a passenger for extended periods.

Overall, the Honda Monkey is a versatile and fun little bike. It caters to a wide range of riders, but again, it isn’t going to be the best small motorcycle for everyone.

KTM 125cc Engine & Transmission

Being a Honda motorcycle that’s been around for so long, these are very reliable and durable machines. They aren’t extremely fast or peppy, but they still deliver a fun and exciting riding experience.

With the same engine as a Honda Grom, these bikes have a reputation for reliability as well as performance. Now, of course they arn’t going to rip like a 125 motocross bike, but that’s okay.

Paired with a 5-speed transmission, these bikes produce plenty of urban-worthy power.

Horsepower

The stock Honda Monkey makes 9.25 horsepower. I have seen some modded Monkes that produce a little more horsepower, but having more HP isn’t necessarily the most important factor to consider.

Instead of producing maximum horsepower, Honda has designed this engine to produce a very useable power and delivery. While 9.25 HP doesn’t look impressive, it is still a very usable and capable motorcycle.

Top Speed

Topping off at 65 mph, the Honda Monkey top speed is neither slow nor fast.

However, 60-70 miles per hour seems pretty quick when you’re sitting so close to the road. Here’s a video of someone getting Monkey up to 113 km/h (71 mph).

Ultimately, the top speed of a stock 125 Honda Monkey is typically ~65 mph. However, it isn’t too difficult to get these little bikes to go faster with taller gearing, an aftermarket exhaust, or some other high-performance mods.

Just like having a large horsepower number, a fast top speed isn’t usually the most important spec to worry about. When it comes to being usable, this 125cc engine makes very useable power.

Maintenance

In line with most Honda motorcycles, dirt bikes, and ATVs, the Monkey is extremely dependable and should last you a long time. With that, it does require some regular maintenance to keep it running smoothly.

However, the amount of maintenance (both intervals and checklist items) pales in comparison to a motocross bike or cross-country bike.

Here’s what the maintenance looks like for the Honda Monkey.

Honda Monkey Maintenance Schedule

Here’s a screenshot image of the service and maintenance schedule for the Honda Monkey 125. According to the owner’s manual, the majority of the maintenance needs to be done every 4,000 miles.

It breaks down into the following:

• After the first 600 miles (1,000 km)
• 4,000 miles (6,400 km)
• 8,000 miles (12,800 km)
• 12,000 miles (19,200 km)
• 16,000 miles (25,600 km)
• 20,000 miles (32,000 km)
• 24,000 miles (38,400 km)

In addition to the mileage intervals, you’ll also see a few different gray squares with a letter in them, as well as a black circle with the letter “R” inside of it.

Here’s what those items stand for:

I – Inspect (clean, adjust, lubricate, or replace, if necessary)
L – Lubricate
R – Replace
C – Clean

NOTE: I realize that the image above is a little pixelated and hard to read. Below are the items typed out for easy reference.

After draining – 1.0 US qt (0.9 L)
After draining & engine oil filter change – 1.0 US qt (0.9 L)
After disassembly – 1.11 US qt (1.05 L)

Honda Monkey Handling

The 125 Honda Monkey is easy to ride and handles great, however, that hasn’t always been the case.

Granted, the older bikes weren’t terrible, but they are much better now. The newer Honda Monkeys feature an inverted hydraulic fork suspension up front and twin rear shocks in the rear.

The updated suspension, combined with the chunky tires and cushy low seat height, makes for an enjoyable and smooth ride even over some rough pavement.

Here are all of the different handling specifications to know:

Weight

As mentioned, the curb weight of a stock Honda Monkey is 230.6 pounds.

While I wouldn’t call that “light” for such a small 125 motorcycle, it isn’t “heavy” for a street bike. Overall, 230 pounds is on the lighter side of a motorcycle and the bike is light enough to control and maneuver.

As a comparison, the TTR 125 weight is 198 pounds and the CRF125F weight is 194 pounds. Of course, those are dirt bikes and not street-legal motorcycles, so that does make a difference. Street bikes weigh more because they have a lot more requirements to operate on the road.

Honda Monkey Weight Limit

Does the Honda Monkey 125 have a weight limit? Yes, it does.

The owner’s manual states that the maximum weight limit is 231 pounds (105 kg) for this motorcycle. Also, this includes your weight plus any gear and anything else like a tool kit, etc.

NOTE: The manual also states that this motorcycle is not designed to carry passengers. It says that the passenger capacity is for the rider only.

Seat Height

Along with its unique, retro look, the Honda Monkey seat height is 30.6 inches. Also, the motorcycle will squat down slightly when you get on it.

Depending on your specific inseam measurement, a seat height of 30.6 inches is typically the ideal height for someone who is around 5’1″ tall.

Surprisingly, there are a handful of other street-legal motorcycles with an even shorter seat height. So, while this isn’t technically the smallest or shortest option out there, it’s still my favorite for many reasons.

Suspension

One of the best upgrades that the Monkey has seen over the recent years is the suspension.

Inverted fork and twin rear shocks – Now that these motorcycles have a sportbike-like suspension, they are awesome. The Monkey’s inverted front forks and chunky tires are the perfect marriage for gripping the road.

Is the Honda Monkey Bike Any Good?

Monkeys are awesome. And I’m not just talking about animals or bands. When it comes to the overall view of these motorcycles, there’s not much bad you can say about them.

Are they fast or powerful? No.

Are they super high-performance machines? Nope.

They are fairly inexpensive, fun little neighborhood motorcycles. And that’s exactly what makes them so popular and fun to ride.

Of course, not everyone is going to like this type of motorcycle, and that’s okay. For anyone else who is in the market for a little mino-moto like this, the Monkey is great.

Here are some of the positives and negatives of a Honda Monkey:

Positive Reviews

• It’s easy to maneuver
• Short and lightweight encourages confidence
• Looks awesome!
• Reliable (it is a Honda, after all)
• Very fuel efficient (over 100 miles per gallon)
• Easy/infrequent maintenance
• Affordable
• Electric start
• Great working headlight

Negative Reviews

• Not good on high-speed highways or for long distances
• Doesn’t hold a lot for a street bike
• A small fuel tank (but does get good miles per gallon)
• Not the best off-road
• Too short for taller riders
• Harder to see the small motorcycles in traffic

Overall, these are solid little motorcycles for what they’re designed to do.

If you’re looking for a motorcycle to have fun on, and not to travel, race, etc., this is definitely a good bike for that. With that, it really isn’t the best option for traveling long distances or for serious trail riding.

Buyers Guide (Best Year, Pricing, etc.)

If, after all of that, you’re still interested in this enduro, here are a few things to know about buying one:

• The best year Honda Monkey to buy
• What they are worth used
• Best place to buy one

Best Year

Picking the best year of a Honda Monkey isn’t as straightforward as one might think.

Technically, the newer the bike, the better the performance. However, some prefer an actual vintage Monkey.

The older models are still “good” motorcycles, but if you can find a 2019 or newer, that would be ideal. The 2019 models are inspired by the Honda Grom and do have much better suspension and handling.

How much does a Honda Monkey cost?

BASE MSRP: $4,299
Destination Charge: $200
Freight Surcharge: $100

How much is a used Honda 125 Monkey worth?

Admittedly, buying a new bike can sometimes be easier than hassling with “Craigslist People,” you can usually save quite a lot of money buying a used bike instead.

Since these motorcycles have been since the 1960s, the price range varies a bit. However, a used Honda Monkey motorcycle will cost around $4,000 if you buy a used one.

Surprisingly, I was able to find quite a few on Facebook Marketplace. They weren’t all located as close to me as I would like, but they were all within a “reasonable” drive from my house. Here are the ones that were close enough to me that I would consider driving to.

For the record, I don’t encourage you to look these up if you don’t plan on buying one. After putting this list together, I’m seriously chompin’ at the bit to go buy one. Soon!

Anyway, here are the best Honda Monkey motorcycles that I found:

2019 Honda Monkey (blue) – $4,000
2019 Honda Monkey (yellow) – $4,000
2019 Honda Monkey (red) – $3,850
2021 Honda Monkey (blue) – $4,000
2021 Honda Monkey (blue) – $4,250
2022 Honda Monkey ABS (yellow) -$4,500
2022 Honda Monkey (black) – $4,500
2023 Honda Monkey ABS (yellow or red) – $4,249 (plus $300 in charges from Honda, new)
2024 Honda Monkey ABS (red or black) – $4,299 (plus $300 in charges from Honda, new)

Without adding them all up and dividing by 11, you can see that the average price is about $4,000. If you’re planning on buying a new one, you should expect to pay about $4,700.

Unfortunately, buying a used Monkey doesn’t save you a whole lot of money over buying a new one.

Is Kelley Blue Book Price Accurate?

After looking over FB I wanted to see what Kelley Blue Book listed the value at. Here’s a screenshot of a 2020 Honda Monkey’s value, according to KBB:

According to Kelley Blue Book, these motorcycles typically list for $4,470. That’s close enough to my local area’s average price of $4,000. Here are two prices from KBB:

Trade-In Value: $3,070
Typical Listing Price: $4,470

I also checked JD Power to compare. Again, the price range is right in line with what we’ve already found. JD Power lists the following prices:

Suggested List Price: $3,999
Low Retail: $2,530
Average Retail: $3,330

Where to Buy?

As you know, if you want a new 2023 or 2024 Honda Monkey 125 motorcycle, drive your truck over to your local Honda dealer and pick one up.

If you want an older model, I recommend checking your local Facebook Marketplace listings. As mentioned, there were quite a few options in my area.
