Welcome to another Motocross Advice ultimate guide. This guide will provide the background and history of two-stroke dirt bikes and answer some burning questions. You’ll also find a full product list with specifications of every two-stroke dirt bike available in 2023.
What is a two-stroke dirt bike?
What is a two-stoke engine?
Before getting into the history and specifics of two-stroke dirt bikes, let’s go over some basics of what exactly is a two-stoke engine?
I think the best way to explain is using the Wikipedia reference below.
From the explanation above, it’s obvious that two-stoke dirt bikes would become popular, low weight, high power, perfect match for the dirt!
Two-stroke dirt bike history/background
Traditionally, dirt bike engines were always two-stroke. The very first dirt bike brought to market by Yamaha in 1968 the DT-1 was a 250cc two-stroke.
Two-stroke dirt bikes were hugely popular during the 1980s and ’90s, but it was around ’96 when all that changed. The American Motorcycle Association (AMA) introduced new regulations, which allowed new four-stroke 450cc dirt bike engines to compete directly against the dominating two-stroke 250cc. The bigger capacity of the four-stroke class was to even out the power advantage as two-strokes deliver far more power per CC.
It was then that a four-stroke movement began. Yamaha introduced a four-stroke dirt bike engine to market, the YZM400F prototype in ’97. As a leader in the field, many manufacturers followed Yamaha, all but abandoning two-strokes. The turning point was when the YZM400F prototype four-stroke bike ridden by Doug Henry won the Supercross final in Las Vegas in ’97. Two-stroke dirt bikes began to lose traction with development and riders alike. The new four-stroke movement was kick-started.
The two-stroke dirt bike engine was claimed to be less environmentally friendly. With stricter emissions standards in force, the four-stroke engine became the norm from the late 90s. It seems that the powers that be failed to realize that the larger four-stroke engine also produced emissions. With the benefit of hindsight, we know that two-strokes can be developed to run more efficiently.
The debate about whether two-stroke or four-stroke is best still rages on. No doubt you will have encountered some discussion as an enthusiast. Historically, two-strokes received unnecessarily lousy press from many quarters. Environmental issues were often cited, but not substantiated. Thankfully for two-stroke lovers, certain manufacturers have stuck with the format. Leading the way are Austrian stalwarts KTM, but they are far from alone as we will see later in the article.
Two strokes are here to stay. Motocross die-hards never left. Regardless, two-stroke engines lived on, not least for use in offroad dirt bikes.
There is something very emotive and evocative about the smell, sound, and characteristics of a two-stroke engine. The way they launch from the start line, the more lightweight feel to the body and that distinctive high-pitched bark are all something you may have come to love.
Well, sit tight and hold on to your helmet because two-stroke is back with a vengeance. Read on as we compare two-stroke and four-stroke engines and then get into the product guide.
Two-Stroke Dirt Bike Product Guide 2023
Best Kids Two-Stroke Dirt Bikes 2023
50cc two-stroke dirt bikes are entry-level, lowest machines ideally suited to younger riders from aged four and up. From aged four, you can introduce your child safely to a 50cc two-stroke dirt bike. If your child can balance on a standard bicycle, then they should be good to go on a 50cc.
This is a great way to introduce new riders to the world of two-stroke dirt biking and can set them on a path that will mean they are accustomed to the power and thrust of a two-stroke. As with all dirt bikes, you should ensure all the proper protective gear is provided, including helmets, boots, and chest protectors.
You can also apply limiters to the throttle to prohibit excessive speed in preliminary rides. By ages five and six, your child can be having lots of fun around the tracks and trails, and this can make for great family outings.

Best Two strokes – Husqvarna
One of the oldest recognizable brands in motorcycling, Husqvarna began successfully producing two-stroke dirt bikes in the 1960s. These two-stroke bikes were part of a movement that meant the dominant four-stroke market became less prevalent.
Two-stroke Husqvarna bikes went on to win many motocross and enduro championships. Many readers will know that the Husqvarna brand was born in Sweden. Still, the company switched hands several times, even being owned by BMW. Now owned and manufactured at KTM AG in Austria, the two brands share a good deal of technologies, especially when it comes to a two-stroke.
Wherever you see a T in the model lettering on a Husqvarna bike, it will be a two-stroke. If you’re interested, C denotes a motocross dirt bike, and E is for an enduro dirt bike. You won’t see an ‘F’ in the products within this guide, as that means the bike is four-stroke.

That trademark orange color could be seen in motocross from around 1996. A very wide range of two-stroke models is available from KTM. As we mentioned earlier, the manufacturer kept on producing and improving great two-stroke bikes and technology when other manufacturers halted production.
KTM is responsible for the TPI (Transfer Port Fuel Injection) system in their enduro range, which electronically injects fuel into the cylinder. This technology has eliminated the need for premix oil and gas. It has made two-stroke engines much cleaner as well as more fuel-efficient than carburettor two-stroke engines.
Manufactured in Austria, they continue to be a quality, world leader as well as competition winner when it comes to best motocross dirt bikes.

Best Two strokes – Yamaha
Although founded in 1887, Yamaha Corporation only started producing motorized vehicles in the 1950s. In 1954 the YA-1 Yamaha was born – a 125cc two-stroke road bike to rival German and British designs. Following the success of that bike, the Yamaha Motor Co. was born.
Yamaha won its first competition in 1964 with a 250cc two-stroke at the Belgium GP and sales were a huge success. They went global and in 1965 released an early version of KTM’s TPI, where oil was injected directly into the fuel chamber. Nowadays the Yamaha motorbike is a tour de force in the motocross world and repeatedly excels at competition level.
Although instrumental in helping the industry towards four-stroke with the YZ400F circa 1997, the company has strong roots with two-stroke and is now producing viable options.

Best 65cc to 100cc Two Strokes 2023 Mini and Junior Motocross
The next category for consideration is the mini and junior 65cc to 100cc, generally two-stroke dirt bikes for 10 year old riders and over. But, you should remember that when making a cc selection, it comes down to height and weight, as well as riding experience.
If you are a new rider under 5 feet tall, or under 10 years old but have some experience, any dirt bike under 110cc could be for you. The differences between 65cc to 100cc and the peewee or 50cc class are that some bikes offer proper gears, clutch systems, and race-ready suspension.
The bikes in this category can be a mini version of 125cc plus professional bikes. If you need a super light dirt bike or a bike with low ground clearance, then you could comfortably ride one of the following at any age. These bikes are ideal at competition level, or just for fun.

Although owned by premier brand KTM, GasGas values have always set out to offer reasonably priced dirt bikes. The EC 300 is no different, with an electric starter, affordable components (great news if you need to repair or rebuild) and a bottom end torque rather than crazy top-end this could be the ideal step-up for some. Watch a video of the EC Range here.

Two-Stroke Dirt Bikes Vs Four-Stroke Dirt Bikes Q&A
How does technology differ between two-stroke and four-stroke?
At a basic level, the secret is in the name of these engines. A two-stroke engine completes three stages of the combustion cycle (intake, compression, and exhaust) in two strokes of the piston to create propulsion. A four-stroke takes four strokes to complete the same job.
Inside a two-stroke engine, the first stroke will intake, compress and combust a mix of fuel and lubricating oil. This mix of gas and oil can be mixed manually, known as a premix, or mixed automatically internally using TPI or transfer port fuel injector technology.
The next stroke then occurs in the chamber – expand, refill, and exhaust. The system in a two-stroke engine eliminates the need for valves, whereas a four-stroke relies on valves. Due to two strokes instead of four, it means two-stroke engines can be more efficient.
There are 30-50% less moving parts in a two-stroke engine compared to a four-stroke, which can save you money. Fewer parts mean fewer repairs and less overall waste. A four-stroke engine can weigh up to 50% more in the engine alone than a comparable cubic centimetre two-stroke engine. Things are changing in this regard as four-stroke engines are developed to become lighter.
While a two-stroke engine produces less overall waste, the faster moving parts can mean more fuel consumption. This process can result in increased emissions, depending on how hard you ride. But, direct injection and catalytic converters can mean reduced unburned hydrocarbons in emissions, and two-stroke engines are being improved each year.
How do two-strokes ride vs Four Strokes?
A two-stroke engine is lighter. This can make it faster than it’s four-stroke equivalent, giving you a substantial kick off the mark. Two-stroke dirt bikes are not just quicker at accelerating, but being lighter overall means two-stroke dirt bikes are far easier to slow down.
One thing to note is that there can be less engine-braking with a two-stroke bike. Be wary if you are jumping from a four-stroke onto a two-stroke as you barrel into turn one! Transversely, a four-stroke dirt bike is heavier so it can be slower when accelerating away and harder to stop all that extra weight when braking.
On a four-stroke, you do get more engine-braking simply because there are more moving parts and the bikes are heavier. When riding a four-stroke bike, you experience a more gradual acceleration and therefore a far less snatchy experience as there is a more linear distribution of power. This can be great for firmer courses or where more control is required, as you experience less wheelspin on a four-stroke dirt bike.
Two-stroke engines excel on the sand and loose courses or where out-and-out speed and agility are required. Riders moving from four-stroke to two-stroke for the first time are often invited to the ‘dark side’, and many never look back.
When considering bikes, it can be a case of finding a model that suits you. One example is a KTM two-stroke dirt bike, as some report, they are easier to control at lower speeds. Transversely, Yamaha bikes, for example, are well known for being more challenging to use at lower speeds and beg to be ridden fast. Users report Yamaha can feel ‘on or off’ with a lag between the top and low end, making it harder to control on more technical trails. But it has excellent torque even at the top end of first gear and can be more fun.
More gear shifting is required with a 2 stroke dirt bike compared to four-stroke with closer ratios, meaning you can’t linger in each gear for the durations like you may be able to with a four-stroke.
I want to buy a 2 stroke dirt bike. What do I need to know?
Firstly you should consider your own riding experience and the kinds of riding you intend to do with your new two-stroke dirt bike. Your choice will depend on your riding style and ability.
There pros and cons when choosing from a two-stroke dirt bike manufacturer. Similarly, you need to think about which cc class you should purchase.
If you are an experienced rider, for example, having ridden a 250cc four-stroke, a 250cc two-stroke may be a shock to the system although manageable within a few rides.
If you’ve decided two-stroke is for you, next, consider the terrain you ride most. Most 2 stroke dirt bike manufacturers offer motocross and offroad versions of the same dirt bike. With a whole host of models and manufacturers available, you should aim to try before you buy. Many showrooms and second-hand sellers should offer you this option before making a purchase.
Are 2 stroke dirt bikes good for beginners?
Yes and no. The benefits are that if you start with a two-stroke dirt bike, you’ll be immediately accustomed to the acceleration and handling style and able to control the throttle from the outset.
But, with the more snatchy nature and potential whiskey throttle of a two-stroke dirt bike, this could cause looping or tip-overs for less confident riders. This could mean two-stroke dirt bikes are harder for newer or youth riders. The solution here is to buy a lower cc bike than your ego is telling you you need. If you are looking at a 250cc, maybe try a 125cc/150cc instead. Trust us when we say, you will have more fun riding harder on a smaller engine, then you will battling to stay on a bigger two-stroke.
Similarly, there is a limited range of dirt bikes available in the beginner two-stroke category, but this is changing all the time. Newer models are available each year with the resurgence of two-stroke dirt biking. You’ll find the best beginner two-stroke bikes available in our buying guide, later in this article.
With four-stroke dirt bikes, for more linear throttle response, there are more market options for beginner four-stroke dirt bikes than a two-stroke, but that’s not why you’re here.
It’s also worth considering that two-stroke dirt bikes for beginners are lighter and can be more suited to people of a smaller build. A lighter bike is more comfortable to transport, to lift and to wheel and therefore to control. Plus a higher power to weight ratio means it will be quicker and, let’s face it that means more fun.
Are two-stroke dirt bikes more powerful than four-stroke dirt bikes?
To answer the question, yes, the two-stroke dirt bike engine effectively produces twice the power of an equivalent displacement four-stroke dirt bike. Plus a lighter engine means a higher power to weight ratio. You also feel that power more quickly and responsively. A four-stroke dirt bike has more torque at lower RPM, which is excellent for trundling along through trails and the technical terrain. A two-stroke dirt bike has more torque at higher RPM, which is suited for speedier terrain, woods, jumps, and boulders where instant power is required.
There is added power from that iconic fat, bulging pipe on the two-stroke dirt bike. This pipe is designed to reverberate sound waves, sending them back to the engine.
For a brief moment, this pipe forces exhaust back inside the cylinder, creating a supercharger effect. It is here that the ‘on pipe’ power band can be felt. For inexperienced riders, being ‘on the pipe’ delivers an insane amount of raw power instantaneously, which can be off-putting (or great fun).
Which is best for me – a two-stroke dirt bike or four-stroke dirt bike?
This depends on several things. You may wish to consider your overall budget to purchase and maintain your dirt bike. Next consider your riding style, your intentions, and your attitude.
If you like the idea of less initial outlay and less money on parts, a two-stroke is for you. If you want to ride fast, loose, rough terrain, or motocross style, a two-stroke dirt bike will be for you.
If you prefer something more modest with more control and are happy with the potential for expensive parts and more service costs in the long run, then a four-stroke could be for you.
You should consider your preference for noise levels too. Some two-stroke dirt bikes can be twice as loud as a similar four-stroke dirt bike, but some may prefer that trademark ying-ying. And let’s be honest. The smell of two-stroke is heaven.
Meanwhile, motocross four-stroke engines have a louder and deeper grunt than a motocross two-stroke engine. Still, cross-country four-stroke dirt bike engines can be much quieter than two-stroke equivalents. This may be handy if you are dealing with local authorities, residents committees and anti-dirt bike campaigners!
When it comes to attitude, if you know your riding style will match a two-stroke and prefer something more fun and zesty, the two-stroke bike could be the one. Two-stroke dirt bikes are also great for those of you who like to tinker and take things apart, which leads us nicely to our next point.
Are two-stroke dirt bikes easy to maintain?
Yes. That would be the shorter answer. The longer answer is that cleaning a two-stroke engine is far more manageable. However, the heat and faster-moving parts in a two-stroke dirt bike engine can cause more frequent repairs than a four-stroke engine.
The trade-off here is that parts are cheaper for two-stroke dirt bikes.
The mix of fuel and oil and fewer parts doing all the work also contribute to more maintenance and repairs in a two-stroke engine. In contrast, a four-stroke engine has more moving parts and a dedicated lubricant, meaning far less everyday wear and tear.
Four-stroke engines can, therefore, last much longer than two-stroke, depending on riding style. When a four-stroke does need a big service, things can add up though. There are far more complex parts and more of them.
If you have a garage or shop and are into stripping bikes back, cleaning and reassembly, two-stroke bikes are considered child’s play compared to a four-stroke dirt bike engine.
You also need to think about extra oil and spark plug expenses with two-stroke dirt bikes. Overall, the less initial outlay in first place for the purchase of a two-stroke dirt bike is a consideration here when crunching the numbers.
So if you’ve decided that a two-stroke dirt bike is the one, you may be wondering what market options are out there. Read on for our handy guide that lists the best two-stroke dirt bike market options available in 2023. You’ll find a range of reputed brands with an engine displacement to suit every riding style and experience level.
