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 2020.

What is a two-stroke dirt bike? 

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.

Best Kids Two-Stroke Dirt Bikes 2020 

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.

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.

The next category for consideration is the mini and junior 65cc to 100cc two-stroke dirt bikes, generally for riders aged 10 or over. But, you should remember that when making a cc selection, it comes down to height and weight, as well as riding experience.

Best Two-Strokes-GasGas 

GasGas is now a subsidiary of KTM, having been acquired by the Austrian giant in 2019.

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 comlete 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 devel
