The Best 50cc Dirt Bikes Buying Guide

Before buying a 50cc dirt bike, it might be necessary to understand what some of the main specs mean for you. Let’s highlight the top things to consider before you buy a 50cc bike for your little biker.


The terrain your kid will be riding their bike on is a major factor when choosing the type of dirt bike to buy for them. Generally, there are four kinds of dirt bikes depending on the riding terrain. They include motocross, trails, enduro (dual-sport), and trials. However, when buying a 50cc dirt bike for your kid, the MX and trail bikes will be your primary consideration.

Trail bikes typically have lower specs than MX bikes and therefore cost less. They also have a softer suspension that makes them comfortable for long rides and is generally easy for beginners to ride.

On the other hand, motocross bikes are better suited for advanced riders as they are faster, more lightweight, and have a stiffer suspension. They also feature a higher seat height than trail bikes which makes them better for more experienced kids.

Motor: 2-Stroke Vs 4-Stroke

Most 50cc dirt bikes come with either a 2-stroke or 4-stroke engine, depending on the brand. Air-cooled 2-stroke engines are typically more lightweight and have more horsepower than 4-stroke engines. It makes them more ideal for motocross racing and 4-stroke bikes for trail riding.

While they might be more challenging to control due to the frequent gear shifting, 50cc dirt bikes for kids such as the KTM 50 SX Mini and the Yamaha PW50 come with fully automatic transmissions.

The 2-stroke dirt bikes also have a less complicated engine than the 4-stroke models and are more efficient and cheaper to replace. However, they also require more frequent maintenance and are louder than 4-stroke dirt bikes.

On the other hand, 4-stroke motorcycle engines are more complex as they have more moving parts than 2-stroke engines. Generally, a 4-stroke engine executes two crankshaft revolutions to achieve one engine cycle, unlike a 2-stroke engine that performs one.

While it might be less efficient than the 2-stroke, the 4-stroke type delivers a steadier power output for a smoother ride. It makes them more suitable for beginners and for navigating dirt trails as the bikes require less effort to control.


The best 50cc dirt bikes are generally made for young riders and typically feature a semi-automatic transmission or a fully automatic gearbox.

While mini dirt bikes such as the Yamaha TT-R50E and the Honda CRF50F feature a 3-speed semi-automatic transmission that makes it easier to navigate through uneven trails, the Yamaha PW50 comes with a fully automatic transmission.

On the other hand, the KTM 50 SX Mini features a single-speed gearbox that allows your young rider to concentrate on handling the bike at cruise speed and is easier for kids transitioning to motocross racing.

50cc dirt bikes for kids also come with either a Kickstarter or an electric start. The Yamaha TT-R50E features an e-start which allows your kid to start without the help of an adult. Additionally, it is more convenient for trail riding where you might need to start your bike in the middle of a hill. However, most 50cc dirt bikes come with Kickstarter, which is a manual process, and many kids will need adult assistance to use it.


Generally, trail 50cc dirt bikes use non-adjustable suspension systems and have low ground clearance, unlike MX bikes that feature adjustable upside-down forks. USD forks have better responsiveness to sudden changes in maneuvering the bike, unlike conventional forks.

Furthermore, the adjustability feature allows you to change the seat and handlebar height for customization. On the flip side, the adjustments may also alter handling performance and braking stability when riding at high speed.


The best 50cc dirt bikes are typically easy to maintain and only require regular check-ups to keep them in top condition. Additionally, it is essential to care for the bike after every ride by cleaning to prevent wear and oiling the parts to prevent corrosion. We also recommend removing the starter battery and hooking it up with a trickle charger to prevent it from degrading.


What is the best 50cc dirt bike for kids?

Factors such as budget, age, and skill level will determine the best 50cc dirt bike for your kid. The Yamaha PW50 is an excellent option for young 4-year olds, while the TT-R50E, Honda CRF50F, and Suzuki DR-Z50 are suitable for older riders. On the other hand, the KTM 50 SX Mini is ideal for advanced riders keen on motocross racing.

What is the fastest 50cc dirt bike?

The maximum speed you can expect from a trail mini dirt bike is between 25mph and 40mph and up to 45mph for motocross bikes. However, trail dirt bikes typically come with built-in throttle limiters, while speed kits are sold separately for motocross bikes.

How safe is a 50cc dirt bike?

While riding motorcycles does come with some risks, 50cc dirt bikes come with features that make them safe for young kids to handle. They include heat shields on the engine and exhaust, speed limiters to adjust the maximum speed, and training wheels to build confidence as they learn to ride.

How much does a 50cc dirt bike cost?

The cost of a 50cc dirt bike depends on the brand and its features. The trail dirt bikes on this list range between $1,600 – $1,800, while motocross bikes are typically more expensive, with the most affordable going for at least $3,800.

    My motorbike addiction began with 50cc at 5 years old. I rode motocross as a teenager & into my 20's when I worked as a mechanic. This helped me to see the light—sportbikes & cruisers became a passion. Now I'm building BikersRights to be the #1 resource for everything on 2 wheels!
