Kids 50cc Dirt Bikes

I want to start by saying, there are a ton of “copies” out there. Sure, you might be looking at a brand new dirt bike for your child at say $500, and be thinking that’s a good deal. That’s not going to cut it.

Motocross bikes aren’t cheap. Even a quality minibike for kids is going to be $1500+ from a leading brand like Honda.

But, these types of bikes WILL stand the test of time if maintained properly. A cheap Chinese copy, won’t…

I’ve suggested the two bikes I think are the best for beginners below. Looking at another brand? No problem, just make sure it’s on this list, and you won’t go far wrong…

The Best Beginner Pit Bike for Kids

Honda CRF50

So, they just hit their first jump on a bicycle?

The next step for your kid is to couple those skills with something that doesn’t require pedals…and the Honda CRF50 gets my vote.

View in gallery

Why? It’s small, agile, has a smooth power delivery, and is semi-automatic (no need to learn how to use a clutch at this stage).

The popularity of the Honda CRF50 knows no bounds. There are literally race series (for kids and adults), dedicated to the bike across the world. It’s also one of the most popular pit bikes for adults. And, that’s because it’s a top bike, from a leading brand.

But what makes it suitable as a first time dirt bike?

Price

Let’s just hit you straight with the price; the M.S.R.P is a little shy of $1,600. You’ll be able to pick up a used example for under $1,000 on eBay, on occasion.

And, I know you can buy a “pit bike” off Amazon for like $500 or less.

PLEASE don’t do that. And, PLEASE read carefully before you make your decision.

Bike Setup

As we’ve already mentioned, the CRF50 pit bike is perfect for beginners. It’s light as anything (110lbs), and has a lower seat height than most other 50 minis; 21.6 inches.

Better still, being a 3 speed semi automatic, it’s just like riding a bike, your kid isn’t going to have any problems getting used to it.

Jump over to this page on the Honda website for the full specification list.

Suspension

I’ll admit, the bike’s suspension is limited in terms of performance (this is a starter bike after all).

You’ll get a basic telescopic front fork, with a single shock at the rear. But it’s fit for purpose , ideal for 4 year olds and up to 6 year olds to begin with.

However, within 6-12 months (especially for bigger and heavier riders, so 5 year olds and 6 years olds), you might want to think about upgrading the fork and rear shock springs. A Honda dealer will be able to advise on the correct weighted springs.

Power Delivery

The smaller 50cc bikes tend to have a smoother power delivery than bigger bikes. When they progress to a 65cc or 85cc motocross bike, they’re going to have a shock; the powerband on those bikes can kick in aggressively.

Your kid won’t have a problem with that here…

Honda integrates a 49cc four stroke engine (known for excellent torque), with ultra-smooth power delivery. And, for the first few rides, you can even limit power by adjusting the throttle limit screw; no need for an accident.

Reliability

Over the years, I’ve had plenty of Honda’s, and not just bikes. I’ve had a CR80 (my first bike), CRF250 (motocross racing), CR250 (enduro racing), and even a petrol lawnmower (well, for cutting grass)!

Compared to other motors I’ve used, Honda’s are just bullet proof, and I have no problem recommending them to anyone.

The CRF50 isn’t highly tuned (but can be). With minimal stress on the engine, it’s going to stand the test of time, and not cost a fortune to maintain.

Availability (and price) of Parts

It doesn’t matter how reliable or well maintained a dirt bike is, at some point you’re going to need parts.

Buying a $500 poor quality “no-name” bike of Amazon?

Guess what? It’s going to break (A LOT) and when it does, you won’t be able to find parts.

What you will find though, is the manufacturer will happily take another $500 for a new bike (because that’s what you’re gonna’ need)!

You won’t have that problem with Honda.

Check Amazon, eBay, or leading minibike shops such as Fast 50s and BBR Motorsports for parts.

Review Verdict: Who Needs The Honda CRF50?

View in gallery

If you want to get your kid into dirt bikes, but want something ultra-smooth and easy to ride to begin with, the Honda CRF50 is the bike for them. It’s one of the best dirt bikes for kids that money can buy.

And, it acts as the perfect stepping stone towards bigger bikes such as the KX65, CRF150 and then the full size dirt bikes such as the RMZ50 and YZF450.

Don’t take my word for it. Drop a message on the Planet Minis forum, and see what their users say about the CRF50.

The Best Beginner Race Dirt Bike For Kids

KTM SX50 Mini

Feel like your kid has a knack for riding? Want them to jump straight into racing? Have a bigger budget than the $1600 M.S.R.P, and want something that’s more technologically advanced?

View in gallery

The KTM SX50 Mini is where your money should be at, and here’s why…

There’s a HUGE difference between a 50cc beginner dirt bike like the Honda CRF50, and a bike designed for racing, such as the KTM SX50 Mini.

Long story short, the same level of rider on a Honda CRF50, will go MUCH faster on a race bike such as the SX50 because it has:

More aggressive power delivery and better acceleration
Higher quality suspension to absorb bumps, jumps and offers improved control
Superior brakes, for later braking

Price

I didn’t mean to shock you with the M.S.R.P of the CRF50. If you were shocked, look away now.

The M.S.R.P of the KTM50 is $3,899.

That’s what you need to pay to have a dirt bike for kids that’s going to win races; it’s as simple as that.

Bike Setup

So, what does nearly $4,000 get you in terms of minibike racing?

View in gallery

Well, KTM lists this as a bike suitable for 4 years old through to 10 year olds. Personally, I was already on a CR80 by 8 (nowadays, they are 85s, so something like the YZ85).

I’d suggest this bike for riders 4 years old through to around 6 years old. By 7-10 years old, your kid should be progressing towards a 65cc or 85cc machine.

The KTM is light, weighing under 90lbs (much lighter than the CRF50), and that means your kid can hit berms hard. And the low seat height of around 22 inches means there’s a low center of gravity for increased stability. Better still, you’ll get ridiculous stopping power thanks to top quality KTM disc brakes.

We’ll cover the most important features below.

Suspension

If you’ve been into motocross racing for a while, you’ll know many racers focus on exhaust and engine mods, not suspension.

FAIL!

Suspension is just as, if not more, important. There’s no point having a quick bike, if it can’t handle bumps, ruts, whoops and jumps.

The KTM SX50 dirt bike for kids includes top quality components, the equivalent of which, are used on adult race bikes like the SXF250 and SXF450.

From the box, you’ll get 35mm WP XACT upside down front forks. And, at the rear, you’re kid’s going to feel like they’re riding on water, with the WP XACT Monoshock.

Let’s put it like this, they’ll outgrow the bike, before the suspension needs upgrading; it’s top of the line stuff.

Power Delivery

The CRF50 has a smooth 4 stroke 49cc engine. That’s not going to cut it on the race track. Not only will top speed be slow, they’ll get destroyed on the exit of turns.

By who?

Kids on a KTM SX50 Mini. The SX50 uses a much more powerful 2 stroke 49cc; there’s literally no comparison between the two.

What’s worth bearing in mind, is this is designed for racing. The much more aggressive power delivery will take some getting used to, but will put a HUGE grin on your kids face!

Reliability

It wasn’t until around 2000 that KTMs became popular. Why? Before then, they simply fell apart. Luckily, the build quality has improved massively over the years.

View in gallery

I’ve had newer versions of the SX125 and EXC300, and I’ve been happy with both. They’re now classed as one of the best dirt bike brands for kids and adults alike.

However, this is a highly tuned race bike that will need maintenance (much more in comparison to the CRF50), so bear that in mind.

Availability (and price) of Parts

There are KTM stores globally stocking all manner of components…my nearest one is 10 minutes away. So, you’ll never struggle for parts.

As these are race parts, they’ll be more expensive than the CRF50, but that’s the cost of racing.

Find your nearest KTM dealer here, and they’ll be able to hook you up with whatever you need.

Kids Motocross Gear Guide

Got a bike? Now you need to look for quality dirt bike gear.

It makes me cringe when I see kids on dirt bikes with little, no, or cheap protection.

Don’t scrimp and save when it comes to safety. When motocross bites, it bites hard, so you should be taking a no expense spared approach to safety gear.

There’s a great resource covering reputable dirtbike gear brands here. I’ve used almost all the brands on that list, and you won’t go wrong with any of them.
