  • Authentic motocross frame geometry, the MX350 scales down the dirt bike to size for riders ages 13+ and up to 140 lb (64 kg)

  • Powers riders at speeds of up to 14 mph (22 km/h) with up to 30 minutes of continuous use

Your son will surely love how quiet this thing can get, perfect for a small and quiet neighborhood. This is in contrast with the noisy gas bike counterpart. With the hand smartly crafted throttle and the modest hand brakes, it will only take a little time for your young one to get the hang of this motocross e-bike.

The Razor MX350 has a metal frame and fork that are well-built and sturdy. While it does have actual rubber wheels, it lacks much suspension which makes it not the most ideal drift bike to ride over rough terrains.

Overall, this motocross bike is not just solid and sturdy but also has a great battery. It is relatively fast as well. Unfortunately, though, it offers no speed control so it’s highly recommended for the young ones to wear a complete set of protective gear while on the trip.

Razor MX Motocross Buying Guide

After laying off the features of each Razor MX Motocross bike, here’s a buying guide to help you arrive with the best dirt bike to have:

Specifications

Let’s start with the simplest thing to convey – the specs. While all four of the Razor MX bikes have quite a bit in common, each successive model adds at least a little bit more to the table, from the MX350 to the MX650.

We can see a trend throughout these Razor MX bikes. As Razor puts out a new model, various aspects start to improve, like faster top speeds, improved brakes, and battery life, etc. Does that mean that their newest model, the Razor MX650, is their best bike and therefore the only one worth purchasing?

Well, it’s a little more complicated than that. It is their best electric dirt bike on paper, but that doesn’t necessarily mean it’s the best bike for you or your kid. For one, Razor MX650 is suitable for older and advanced riders while the previous versions are good for starters.

Frame Size

While all four of the Razor MX dirt bikes look similar in size, they all have different dimensions. As you may have predicted, the MX350 is the smallest and the MX650 is the largest. The MX350, MX400, and MX500 are all roughly 45 inches long while the MX650 is 56 inches long and slightly taller as well.

What this comes down to is that while all four of the dirt bikes are designed for ages 13 or 14 and up, adults can still use them as well. However, the best choice to pick for adult usage is certainly going to be the MX650. It has a wide enough frame to more comfortably support a grown-up’s body and it has a much higher maximum weight capacity of 220 pounds.

While Razor’s official website states that their dirt bikes are designed for ages 13 and above, the fact is that many people have posted very positive reviews of their Razor bikes online being used by kids of younger ages.

The MX350 and MX400 have especially been well received by parents of smaller children around the age of eight years old. So don’t feel like you can’t purchase one of these bikes because your child isn’t old enough.

The MX350 and MX400 are arguably a much better size for 7-10-year-olds rather than for teenagers. It actually might be a little difficult getting a teen to fit comfortably on those dirt bikes if they are too tall.

In other words, the MX350 and MX400 are ideal choices for pre-teen ages while the MX500 and MX650 are better suited for teens and adults due to their larger frame and weight capacity.

The Razor MX Bikes in Use

Believe it or not, there are some interesting differences between how these four Razor MX dirt bikes feel when being used. While the gradually improved max speed and battery life seem like small changes, there is a difference when riding these bikes on a variety of terrain.

Let’s start with the MX350 and MX400. For all intents and purposes, these two bikes are extremely similar and their biggest differences are the extra 10 minutes of juice that you can squeeze out of the MX400 model.

Both bikes have rear brakes only and use two 12 inch tires. This is really where their similarities lie. The MX350 and MX400 work at their best on flat surfaces such as asphalt sidewalks but they also handle themselves very well on grass and some dirt.

Acceleration & Performance

I would say that the MX400 has slightly better acceleration, which is probably due to the improved motor wattage, though like the MX350 its acceleration suffers just a tiny bit when being used on dirt, sand, or in light puddles.

Despite these minor issues, both bikes live up to their name. The MX350 and MX400 both work well on off-road terrain. The 12-inch tires are a little thin which allows for some surprisingly reliable steering on bumpy trails and beaches, even when going at the max speed.

As an adult, I was worried my weight would be a problem for these small bikes as I’m right at the weight limit for the MX350 and MX400, but they handled me just fine. That means that a child who is half my weight will handle steering and maneuvering with even better results.

So while I was impressed with these two smaller MX dirt bikes despite a couple of minor hiccups, I was especially impressed with the MX500 and MX650.

Thicker, Larger Tires Make a Real Difference

Unlike the previous dirt bikes, the MX500 and MX650 have dual brakes and larger tires. As mentioned before, the front tire on both of these dirt bikes is 16 inches tall and the rear tire is 14 inches tall.

This makes quite a difference when it comes to off-road handling. Plus, these tires aren’t just taller but they’re thicker as well. This gives them an edge in handling bumpy hills, and because they have stronger motors they can still accelerate and turn at fast speeds in a stable fashion.

As far as I can tell, all of this supports my theory that the MX350 and MX400 are better suited for younger ages whereas the MX500 and MX650 are better suited for teens and up. It’s not that the smaller two dirt bikes can’t be used as all-terrain vehicles, but it’s that the two larger dirt bikes handle these situations much better.

Because the MX500 and MX650 have a dual brake system, they stop easier in the sand and muddy trails. That extra brake in the front wheel really makes the difference in these situations and may well have cut the stopping time by half.

Even though these two bikes are noticeably heavier than their smaller counterparts, they still managed to achieve high speeds and provide a stable and fun riding experience no problem.

Which Razor MX Bike Should You Buy?

If you’re still wondering which Razor MX dirt bike is the best choice for you, then you’re going to have to ask yourself a few questions. The most important one of which is probably this: who are you buying an electric motocross dirt bike for? A 10-year-old? A 16-year-old? Or yourself? Or maybe even all of the above?

You should also ask yourself exactly where you plan on having the dirt bike be used. Will it just be around your neighborhood and a couple of nearby parks? Will it be on the beach? The woods? Or maybe there’s a large valley you like to visit every now and then to unleash your inner motocross superstar?

Once you’ve answered these questions for yourself, then you’ll know for sure which Razor MX dirt bike will be the one you’re meant to buy.

The MX350 and MX400 work well as all-terrain bikes but I believe they work at their best as simple electric vehicles that young kids can really get a kick out of by cruising around the neighborhood.

The MX500 is great for older kids and teenagers thanks to its improved brakes, speed, and off-road capabilities. It works well in urban environments but definitely doesn’t fully shine until you take it off the road.

The MX650 is much like the MX500 but has the size necessary to not only give 13-year-olds a thrilling time but adults as well. It’s the most expensive dirt bike from Razor but it definitely has the most power.

My Recommendations

Even though I enjoyed my time with all four of these Razor motocross electric bikes, there are only two of them that I can whole-heartedly recommend: the MX350 and the MX650. Let me explain why.

All of these motocross bikes are appealing to a wide range of ages, but not all of them hit the mark on that. The MX350, however, is an excellent choice for younger ages due to its relatively small size, but still manages to have the realistic look and design that mirrors actual motocross motorcycles that professionals use.

While I enjoyed the MX400, the price difference between the MX350 and MX400 doesn’t really justify the extra 10 minutes of battery life. It’s still a well-made dirt bike but it doesn’t do enough to be distinctive.

MX650 is Best for All to Share

When it comes to the MX650, this is where Razor really hit the nail on the head. It took the dual brake system and the larger tires of the MX500 but then increased the load capacity so that a much larger range of adults could also enjoy riding this dirt bike. In other words, the MX650 is truly an all-ages dirt bike that could easily satisfy an entire household of riders.

I’m not trying to suggest that anyone would regret buying the MX400 or the MX500, but if you want a dirt bike for your son or daughter, the MX350 is easily the best value out of all four Razor bikes.

But if you want a dirt bike that can be used by many people, plus has the size and the power to really get you immersed in the world of motocross cycling, then the MX650 is easily the best choice in this department.

Concluding Thoughts

Thanks for checking out my rundown of Razor’s MX Dirt Rocket Electric Motocross bikes. While these four electric dirt bikes may seem fairly similar on paper, their differences in size and construction help with making the right purchase for you or a young one in your life.

Anyone of these dirt bikes should provide the exhilarating rush of adrenaline that you’re looking for. I hope you have learned a lot about Razor dirt bikes today, and more importantly, I hope you are satisfied with whichever dirt bike you end up going for.
