1. Yamaha PW50: Best Overall for Beginners
The Yamaha PW50 is the gold standard for entry-level kids’ dirt bikes. Its automatic transmission and shaft drive mean no clutch or chain adjustments, letting young riders focus on balance and steering. The adjustable throttle limiter is a standout safety feature, allowing parents to gradually increase power. Owner feedback consistently praises its durability and ease of maintenance, with many bikes lasting through multiple children.
However, the suspension is basic and the bike is best suited for flat, groomed trails or backyards. Riders over 70 pounds or those seeking aggressive off-road performance will quickly outgrow it. If your child is already comfortable on a bicycle and you plan to tackle rougher terrain, consider a model with more suspension and a larger engine.
- Automatic clutch and shaft drive eliminate stalling and chain maintenance
- Adjustable throttle limiter allows parents to control top speed as skills grow
- Low 21.7-inch seat height suits riders as young as 4 years old
Pros: Extremely reliable and easy to start; Parts and support widely available
Cons: Limited suspension travel may feel rough on bumpy trails
2. Honda CRF50F: Best for Reliability
The Honda CRF50F is a close rival to the PW50, offering a four-stroke engine that delivers smooth, tractable power. It features an automatic clutch and a low seat height, making it approachable for beginners. The electric start is a convenience many parents appreciate, and the sealed drum brakes are low-maintenance. Owner surveys highlight its near-bulletproof reliability, with many reporting years of trouble-free riding.
That said, the CRF50F is noticeably heavier than the PW50, which can make it harder for very small children to maneuver. The suspension is also basic, and the bike lacks the adjustable throttle limiter found on the Yamaha. If your child is lightweight or you prioritize the lightest possible bike, the PW50 may be a better fit. But for long-term reliability and resale, the Honda is hard to beat.
- Four-stroke engine provides smooth, predictable power delivery
- Electric start with backup kick starter ensures easy starts every time
- Sealed drum brakes require less maintenance than disc brakes
Pros: Legendary Honda build quality and resale value; Quiet exhaust is neighbor-friendly
Cons: Heavier than some competitors at 110 pounds
3. Kawasaki KX65: Best for Competitive Racing
The Kawasaki KX65 is a full-on motocross machine for young racers. Its liquid-cooled, 65cc two-stroke engine delivers serious power, and the manual clutch and six-speed transmission require skill to manage. The suspension is fully adjustable, allowing fine-tuning for track conditions. Owner feedback from racing families is overwhelmingly positive, praising its handling and power delivery.
However, this bike is not for casual trail riding or beginners. The seat height is 30.3 inches, and the powerband is aggressive. It also requires frequent maintenance (top-end rebuilds, chain adjustments) and premium fuel. If your child is not competing or is under 10 years old, a smaller, more forgiving bike is a safer choice. The KX65 is a specialized tool for the young racer.
- Race-ready 65cc engine with power valve for broad powerband
- Fully adjustable suspension (inverted forks, remote reservoir shock)
- Lightweight chassis at 126 pounds aids aggressive riding
Pros: Competitive-level performance for motocross; High-quality suspension components
Cons: Tall seat height and manual clutch not for beginners
4. KTM 50 SX Mini: Best for Young Racers
The KTM 50 SX Mini is engineered for young motocross enthusiasts. Its liquid-cooled two-stroke engine and adjustable power valve provide a broad powerband, while the WP suspension offers impressive travel and damping for small bumps and jumps. The automatic clutch simplifies operation, allowing kids to focus on the track. Owner feedback highlights its race-ready performance out of the box.
That said, the 50 SX Mini demands more maintenance than simpler air-cooled bikes, including coolant checks and frequent oil changes. The price is also higher, and parts can be more expensive. If your child is just learning to ride or primarily rides trails, a more forgiving and lower-maintenance model like the PW50 or CRF50F is a better investment. The KTM shines on the track but is overkill for casual use.
- Liquid cooling keeps engine temps consistent during hard riding
- Adjustable power valve and throttle limiter for progressive power delivery
- High-end WP suspension with 9.8 inches of front travel
Pros: Excellent suspension for a mini bike; Lightweight at 98 pounds
Cons: Requires more maintenance than air-cooled competitors
5. SSR Motorsports SR70C: Best Budget Option
The SSR SR70C is a budget-friendly option for families who want a gas bike without the premium price tag. Its 70cc four-stroke engine offers a bit more grunt than 50cc bikes, and the semi-automatic transmission means no clutch work. Disc brakes are a plus, and the 26-inch seat height fits kids aged 7-10. Owner reviews often mention good value for the money, with adequate performance for trail riding.
However, build quality and reliability are not on par with Honda or Yamaha. Some owners report issues with carburetion and loose bolts out of the box. Parts availability can also be spotty. If you are handy with tools and on a tight budget, the SR70C can work, but expect to spend time on setup and maintenance. For those who prioritize reliability and resale, spending more on a Japanese brand is advisable.
- 70cc engine offers a bit more power than 50cc models for growing riders
- Semi-automatic transmission (no clutch lever) eases learning
- Disc brakes front and rear provide good stopping power
Pros: Very affordable compared to Japanese brands; Larger wheels and taller seat suit older kids
Cons: Fit and finish not as refined as major brands
6. Razor MX650: Best Electric Alternative (Not Gas)
The Razor MX650 is included as an alternative for families who want the dirt bike experience without the noise and maintenance of a gas engine. It is powered by a 650-watt electric motor and a 24V battery system, offering a top speed of 17 mph. The twist-grip throttle is intuitive, and the bike is virtually silent. Owner feedback often highlights how easy it is to use and how much kids enjoy it.
However, the MX650 is not a gas bike, so it does not fit the strict gas criteria. Its runtime is limited to about 40 minutes, and the battery takes hours to recharge. The suspension and tires are less capable than gas-powered dirt bikes. If your child wants to ride for extended periods or on rough terrain, a gas model is more practical. The MX650 is best for short, neighborhood rides or as a stepping stone before a gas bike.
- Quiet, no fumes, and low maintenance compared to gas engines
- Variable speed throttle with max 17 mph for controlled riding
- Rechargeable battery provides up to 40 minutes of ride time
Pros: No gas, oil, or spark plugs to deal with; Very easy for kids to operate
Cons: Limited range and runtime per charge
7. Coleman Powersports CT200U: Best for Older Kids (Mini Bike)
The Coleman CT200U is a mini bike rather than a traditional dirt bike, but it is often considered by families with older kids (12+). Its 196cc engine and torque converter offer strong, automatic power. The steel frame is durable, and the large tires provide decent traction. Owner reviews appreciate the low price and the fun factor, especially for teenagers who have outgrown smaller bikes.
However, the CT200U lacks proper suspension, making it uncomfortable on bumpy trails. It also has no safety features like a throttle limiter, and the brakes are basic. This bike is not suitable for young children or for serious off-road riding. If your teen wants a real dirt bike for trails or motocross, a purpose-built model like the Kawasaki KX65 or a larger Honda is a better choice. The Coleman is a budget-friendly play bike for flat, open areas.
- Large 196cc engine provides ample power for teens and adults
- Torque converter automatic transmission eliminates shifting
- Steel frame and 19-inch tires handle rough terrain
Pros: Great value for the engine size; Fun for older kids and adults to ride together
Cons: No suspension on rear, limited front fork travel
Frequently Asked Questions
What size gas dirt bike should I get for my child?
Size depends on age, height, and experience. For ages 4-7, a 50cc bike with a seat height around 21-24 inches (e.g., Yamaha PW50) is ideal. Ages 7-10 often fit 50-70cc bikes with 24-27 inch seats. For ages 10-14, 65-85cc bikes with 28-32 inch seats suit more experienced riders. Always measure your child’s inseam and ensure they can touch the ground with both feet flat.
Is a 2-stroke or 4-stroke better for a beginner?
Four-stroke engines deliver smoother, more predictable power and are generally easier to ride for beginners. They also require less frequent maintenance and have a quieter exhaust. Two-strokes are lighter and have more power for their size, but they demand more skill and maintenance. For a first bike, a 4-stroke like the Honda CRF50F is often recommended.
What safety gear do I need for my child?
At minimum, a DOT-approved helmet, goggles, long pants, long sleeves, over-the-ankle boots, and gloves are essential. For off-road riding, a chest protector, knee pads, and elbow pads provide added protection. Never let a child ride without a helmet, and ensure the bike is equipped with a kill switch and throttle limiter.
Are gas dirt bikes safe for kids?
Gas dirt bikes can be safe when matched to the child’s size and skill, and when proper safety gear and supervision are used. Key safety features include adjustable throttle limiters, automatic clutches, and low seat heights. Always teach your child basic riding safety and start in a flat, open area away from traffic.
How much maintenance does a kids gas dirt bike require?
Maintenance varies by model. Air-cooled 4-strokes like the Honda CRF50F need oil changes every 10-20 hours, chain lubrication, and air filter cleaning. Two-strokes require more frequent top-end rebuilds and mixing oil with fuel. Always follow the owner’s manual. Budget bikes may need more frequent adjustments.
Our Verdict
After comparing specs and owner feedback, the Yamaha PW50 stands out as the top pick for most beginners due to its automatic transmission, adjustable throttle limiter, and proven reliability. For families who prioritize long-term durability and resale value, the Honda CRF50F is an excellent runner-up. Both are safe, easy to ride, and will give years of enjoyment.
