Razor MX400 vs MX350: Detailed Comparison

Design and Frame

When it comes to dirt bikes for kids, we all know that the first impression matters for them the most! A robust design with attractive colors will surely attract the attention of any kid or teenager.

Luckily, both the dirt bikes have an exceptional design with a steel frame.

The Razor MX400 gives a bulky look, which tends more towards the heavy bike kind of look. So, if your kid is a fan of a heavy bike, we recommend buying the Razor MX400.

On the other hand, the Razor MX350 comes with a slim and sleek look, which gives the exact impression of a motorbike. As we always like slimmer bikes, we are highly impressed by the design of the Razor MX350.

Luckily, this dirt bike has also won several toy awards. Thus, the Razor MX350 is an excellent choice for fashion and adventure-loving kids.

As both the dirt bikes have a steel frame, it gives a robust look on the shiny frame sparkling with the sunlight.

Range and Using Time

If you have an excited or hyper kid, we’re sure he would never want to stop riding his dirt bike. Thus, the using time and range of the dirt bike matter a lot for fun-loving kids.

Luckily, both the dirt bikes have a using time of up to 30 minutes. In some conditions, like a smooth surface, less weight, and a fully charged battery, we can expect a longer using time of almost 40 minutes.

Both the Razor M400 and MX350 also have a range of 7 miles.

For kids, we think the range and using time are ideal. As dirt bikes are often for vacations and fun purposes, they don’t have a much longer range. Still, you can go to your school and come back with these dirt bikes, or enjoy a short-distance ride.

For fun purposes like racing with your friends, the range and using time of the Razor MX400 and MX350 are more than enough.

Only a few dirt bikes in the market have a using time of 30 minutes or more. So, the Razor MX400 and MX350 are also better than many others in the market.


As both the dirt bikes have the same range and using time, it’s a tie!


Unlike many other electric scooters in the market, both the Razor MX350 and MX400 come with a lead-acid battery.

The 24V lead-acid batteries of these dirt bikes are the reason for their better performance and longer using time.

However, almost every other electric scooter or hoverboard uses a lithium-ion battery. Although the lead-acid battery is less expensive than the lithium-ion battery, you might need to maintain it more often.

The 24V lead-acid batteries of the Razor MX400 and MX350 are also an excellent choice as other Razor dirt bikes also have the same battery.


As both the dirt bikes have the same battery, it’s a tie!

Motor Power

We already know that motor power tells us about the performance and durability of the dirt bike. As dirt bikes face frequent wear and tear and ride on rough terrains, a robust motor is essential to keep them working in the optimum condition.

Luckily, both the Razor MX400 and MX350 come with a 350W motor. These chain-driven motors are quiet, and won’t make a noise like the other gas-powered dirt bikes.

Thus, the high-torque motors of the Razor MX350 and MX400 will help you enjoy a smooth and comfortable ride, without getting into the hassle of repairing it again and again.

Many other electric scooters in the market also have nearly the same motor power, which does not make them lag in case of performance.

The quiet and powerful motor will always make your off-road adventures a lot more comfortable and fun!


As both the dirt bikes have the same motor power, it’s a tie!


Adventure-loving kids are always looking for the fastest dirt bikes in town that could help them conquer their off-road adventures with ease!

If your child wants the same dirt bike, the Razor MX400 and MX350 will be a perfect choice.

Both the dirt bikes can reach top speeds up to 14 mph. This speed is much higher for children and teenagers.

As only a few dirt bikes in the market would have such a high speed, the Razor MX400 and MX350 are much better than other dirt bikes too.

However, here’s the thing.

Both these dirt bikes have a single-speed mode. It means that you can only ride at a fixed speed of 14 mph. Not more, not less!

We think that the single-speed mode is a bit dangerous because children cannot ride at higher speeds all the time. While taking turns or riding on rough terrains, you need to keep the speed slow.

So, we highly recommend keeping a check on your child while he’s riding the Razor MX400 and MX350. Also, make sure to provide the necessary safety equipment like a helmet and knee and elbow pads.


As both the dirt bikes have the same top speed, it’s a tie!


The weight of the dirt bikes does not matter much if you don’t want to take them on adventures.

If you want to regularly carry and store the dirt bike, the weight will be your top consideration.

The Razor MX350 weighs 48.7 lbs. (22.1 kg). This weight is ideal for kids. However, kids cannot carry this weight. So, you might need to carry and store the bikes for your kid.

On the other hand, the Razor MX400 weighs 62.6 lbs. (28.4 kg). Although heavier than the Razor MX350, the Razor MX400 is still lightweight.

When we compare these dirt bikes to other electric scooters and hoverboards, we don’t find many scooters weighing less than the Razor MX400 and MX350.

So, if you consider the weight, the Razor MX350 will be the right choice. However, if the weight isn’t much important for you, the Razor MX400 will also be a good choice. It all depends on your preference.


Razor MX350.

Weight Capacity

If you have a healthy child, you would probably be looking for a dirt bike with more weight accommodating property.

Both the Razor MX400 and MX350 can accommodate the same user weight, which is 140 lbs. (64 kg).

This weight-bearing capacity is ok. However, when we compare this capacity with other electric scooters in the market, it is a bit less.

Several electric scooters and dirt bikes can accommodate user weight up to 200 lbs. So, in the category of weight capacity, we think the Razor MX400 and MX350 lag from others.

If you put more weight on the dirt bike than recommended, it will decrease the speed and performance of the scooter.

So, make sure your child weighs less than the weight limit of the dirt bikes to ensure optimum performance.

We all agree to look at the price of the dirt bike before its features. When it comes to the price, we think the right choice is to buy the dirt bike that offers all the features at a competitive price.

Luckily, the Razor MX350 is cheaper than the Razor MX400 mini electric dirt bike.

The Razor MX350 also offers many features, although most of the features are common to both dirt bikes.

However, the price of the Razor MX400 isn’t too high.

Razor MX350.


We all know that dirt bikes need to have large and robust tires so that you can easily conquer your off-road adventures and get the most out of your ride.

Luckily, both the Razor MX400 and MX350 electric bike fulfill our expectations in this case.

These dirt bikes come with large and pneumatic 12-inch tires. These knobby tires are made of durable rubber, and ensure the perfect grip with the ground while you ride the dirt bike on dust or rough terrains.

As the tires are made of rubber, we can expect them to give the right bounce and responsiveness as you ride, while staying durable for several years.

Compared to other electric scooters and hoverboards, the tire size is much larger. Many electric scooters have tire sizes limited to 6 or 8 inches. So, the tire size of the Razor MX400 and MX350 is much larger, making it perfect for an off-road dirt bike.

So, you can always rely on these dirt bikes to provide the smoothest and most versatile riding experience with their extra-large and knobby tires.


As both the dirt bikes have the same tire size, it’s a tie!

Braking System

The braking system of both the Razor MX400 and MX350 is exceptional, and they come with a rear braking system.

The hand-operated brakes are super-easy to control and operate for kids and gives them the flexibility of focusing on their ride instead of getting into complicated functions.

Although the rear braking system is good enough for a safe ride, we believe the Razor MX400 and MX350 lag in safety when compared to other electric scooters.

Some electric scooters and dirt bikes have a dual braking system for extra safety while riding.

As the top speeds of both the Razor MX400 and MX350 are much high, the rear braking system might be better.

It would help the dirt bike slow down the speed and stop slowly instead of stopping with a jerk.


As both the dirt bikes have the same braking system, it’s a tie!


The suspension of the dirt bike helps in absorbing shocks while riding on rough terrains.

The Razor MX400 and MX350 do not have any suspension.

However, the robust and knobby tires are large enough to absorb the shock on rocks and bumps and ensure a smooth ride. Thus, we think both the dirt bikes don’t need any suspension when they have extra-large rubber tires.


As both the dirt bikes don’t have any suspension, it’s a tie!

Recommended Age

The recommended age of both the Razor M400 and MX350 dirt bikes is above 13 years.

When we read several customer reviews, we conclude that the company might have been mistaken with the age.

It is because the height and overall size of both the Razor MX400 and MX350 are much smaller for a teenager.

We have seen several customer reviews stating that they bought these dirt bikes for their children of 6 years or above.

So, make sure to consider the dimensions of the dirt bikes before you buy one for your child. Although many people bought them for younger kids, we don’t recommend violating the company’s rules.


As both the dirt bikes have the same recommended age, it’s a tie!


Water-resistance is an advanced feature found in only a few dirt bikes.

Unfortunately, both the Razor MX350 and MX400 do not have any water resistance.

When compared to other dirt bikes, we see that many of them do not have water-resistance technology too.

So, we can say that the robust steel frame and overall geometry of the Razor MX400 and MX350 are efficiently designed to protect them from dirt and dust.

However, we still recommend cleaning your electric scooter after every ride to keep it working in optimum condition. Also, don’t take it out while it’s raining.


As both the dirt bikes don’t have water resistance, it’s a tie!


The color of the dirt bike is essential for a better overall appearance. When it comes to buying a dirt bike for kids, most parents consider the color too.

The Razor MX400 mini electric bike comes in red, white, green and black, while the Razor MX350 is available in blue and black. It also comes in red and black.

As kids always like bright colors, we think the colors of the Razor MX350 are more captivating. They make the dirt bike shine from a distance and attract the eyes of every kid and teenager.

However, the colors you choose depend on your preference.

Retractable Kickstand

The kickstand helps in parking and storing the dirt bike easily.

Luckily, both the Razor MX400 and MX350 dirt bikes come with a retractable kickstand, which helps you to park the dirt bike without any support.

Thus, you can leave your bike outside without looking for a wall to support it.


As both the dirt bikes have a retractable kickstand, it’s a tie!

Razor MX350 vs MX400 Dirt Bike: Who’s the Winner?

After a detailed comparison, we think that the Razor MX350 is the winner!

Although both the dirt bikes have several common features, the Razor MX350 is a cheaper value with better specifications.

It is budget-friendly, lightweight, and comes in a nice overall design.

However, the price and other specifications don’t vary too much. Despite a bit higher price, the Razor MX400 is also a good value for the money.

Both have the same motor power, speed, weight capacity, and braking system. So, you can choose the best one depending on your preference.
