50cc dirt bikes are quite popular, especially among the newest dirt bike enthusiasts. And one of the reasons for this popularity is the presumed healthy balance of speed in these dirt bikes.
But how fast does a 50cc dirt bike go when pitted against others? Well, most of the well-known 50cc dirt bikes average between 25 and 40 mph.
One of the reasons for this relatively high speed, at least for young riders, is the proliferation of lighter and faster models that have a really powerful kick.
Of course, the other logical explanation is that by now, engineers have perfected the art of building dirt bikes for kids and are doing a much better job than in older models.
How Safe Is a 50cc Dirt Bike at this Speed?
One of my biggest fears when I first bought a 50cc dirt bike for my 6-year-old son, a couple of years ago was that it would be dangerous of him to ride at the max 40mph.
And I felt that I would never allow him to accelerate beyond what I felt was a reasonable average at that time: 10 mph.
You likely know about those heart-wrenching crashes that you watch on TV when some adrenaline-charged bikers fall flat after attempting to pull some stunts.
Well, those pictures were never far from my mind every time we went out. But my worries were later to prove to be unfounded as my young champion naturally hardly hit those speeds in his kids 50cc dirt bike.
So in normal circumstances, the 50cc bike is perfectly safe- even without considering that these dirt bikes for kids come with some speed control mechanisms for the extremely concerned parent, as we will see next.
How Can I Control the Speed in My 50cc Bike?
Parents can actually limit a mini dirt bike 50cc top speed for the boy/girl by using some built-in safety mechanisms:
- The Throttle Limiter:
A parent can cap the speed their kid will be doing the wheelies at using the throttle limiter incorporated in most of these dirt bikes.
This helps until they are experienced and brave enough to ride it like their hero, the legendary Jeremy McGrath.
- Safety Kill Switch:
Kill switches are another godsend for worried parents. As the name suggests, they kill the 50cc dirt bike engine if the kid is separated from his machine for some reason.
This not only saves the motor but also protects him/her as well as fellow riders from injury.
Kills switches succeed by grounding out the bike’s ignition to the frame ground or by interrupting the natural ignition supply voltage to ensure there will be no sparks.
- The Presence of Indomitable Brakes:
Another reason why you may never need to worry about how your kid will fair with a 50cc bike is the brakes.
Most, including the DR-X Kid’s Dirt Bike have super-strong disk brakes (front and rear) allowing maximum control over the dirt bikes whenever needed.

How Else Can I Take Charge of My Kids safety with These Dirt Bikes?
Of course, you still need to factor in the usual recommendations and safety precautions before letting your young man/woman soar through the dirt roads with these types of bikes:
- Training And Full-Time Supervision:
The responsibility for adequately training a child to ride lies squarely on the parents. Again, the upcoming rider should be supervised come rain or sunshine so long as they are riding an off-road machine.
Also never allow your boy/girl to ride in places teeming with traffic (It’s illegal anyway in most states!).
- Wear Protective Gear:
He/she should always wear protective helmets, over-the-ankle boots, long sleeves, goggles, long pants, gloves, and every other safety gear before heading out with a 50cc dirt bike speed

And since it has all the necessary control, this bike is sufficient to keep your dirt-crazy boy/girl at an acceptable speed at all times and good enough for stretching the boundaries when the time comes.
Honda dirt bikes are also considered gems and they have excellent types for the beginner class. Led by the Honda CRF50 (This Honda 50cc Dirt Bike Top Speed goes to about 25 mph), Honda dirt bikes are known for their superior design, powerful performance, innovation, and legendary durability.
I bought one bike from the Japanese multinational’s local dealer some years back and it’s still in tip-top shape.
In addition to the excellent riding dynamics, Honda’s simple maintenance and readily available service parts maximize your kid’s time on the roads.
KTM’s dirt bikes and motorcycles are very noticeable because of the huge fan base the Austrian company has among the global riding population…
And so it is likely that you will see your kid’s friend riding KTM’s 50 cc rated dirt bikes such as the KTM 50 SX (topping out at around 37 mph in perfect conditions).

The combination of little user-friendly features includes a built-in throttle limiter, easy automatic transmissions, and low seat heights.
They thus provide an ideal learn-to-ride environment not to mention years of fun because of their tendency to grow with the kids.

My favorite is the Suzuki DRZ50 (maxes out at 33 mph with standard experience).
Their bikes are well-tested and easily outlast generations of youngsters riding through the ranks of dirt biking.
Like in all their four-stroke kid’s bikes, Suzuki prefers a hassle-free approach by adopting a simple yet efficient design in the 50 cc 4-stroke dirt bikes such as the DRZ50.
Automatic clutches are the other common feature in Suzuki 50 cc models and is again very beneficial to learning riders because of the ease of application.
