Razor Electric Dirt Bike Comparisons

Razor Electric Dirt Bike MX125, MX/SX350, MX400 Comparison

Technically, the SX350 and MX400 are both variations of the MX350. The SX50 is the  “McGrath” version, and the MX400 comes in different colors.

The MX/SX350, MX400 can reach a top speed of 12 miles per hour, which is much faster than the MX125.

While, the MX125 model gives a top speed of 8 miles per hour, which is pretty slow.

To be honest, the MX125 may be suitable for a 3 or 4-year-old child, but kids in this age range will outgrow the MX125 quickly. In that case, the MX/SX 350 or the MX400 may be a better gift.

As the MX/SX350 and the MX400 are almost identical in features, we need to take the price into consideration before purchasing one.

Razor Electric Dirt Bike MX/SX500, MX650 Comparison

The MX500 and the SX500 are pretty much the identical bike.

The MX/SX500, MX650 Razor electric dirt bikes are slightly heavy. Even though Razor’s suggested age group is 13+, they actually can be for 10-year-old and up.

But before riding these dirt bikes, your kids need to understand the throttle concept and balance really well on a bike.

Next, let’s make a comparison among MX/SX500, MX650 electric dirt bikes.

1. 500 Vs 650

The MX/SX500, MX650 Razor electric dirt bikes are similar in weight and size, but the determining factor was the bigger motor on the MX650.

The speed-wise difference is noticeable, that is, the MX/SX500 goes 15 miles per hour and the MX650 goes 17 miles per hour.

The MX/SX500 can hold a rider of up to 175 pounds, while the MX650 goes up to 220 pounds.

2. MX Vs SX Frame

The SX500 is the Jeremy McGrath Edition.

The MX seat cover attaches better than the SX. The seat on the MX is much softer than that on the SX.

The MX500 & MX650 rear fork is lower angle making the seat about 1” lower compared to the SX500.

The SX500 has more room in the battery box if you plan to modify or upgrade the battery & controller.

Razor Electric Dirt Bike MX350 and MX650 Comparison

Difference in Top Speed

According to Razor, the MX350 is going to be 14 miles per hour and the MX650 is going to be 17 miles per hour.

Obviously, there is not a huge difference in speed.

The reason for that is even though the MX650 is much bigger and has a bigger motor, more voltage, the fact is this is a much heavier bike and it can also carry a much heavier person.

So when we talk about how fast it can go, it also depends on how heavy the person that’s riding the bike.

How Much Weight They Can Carry

The MX350 can carry a maximum weight rider of 140 pounds, whereas the MX650 goes all the way up to 220 pounds.

So again that speed might depend on if the MX650 carries a 220-pound person compared to 140-pound person on the MX350, which is going to play a big role in how fast these Razor electric dirt bikes go.

Difference in Run-Time

According to Razor, the MX350 has a run-time of 30 minutes, while the run-time on the MX650 is 40 minutes.

We can see that there is not a huge difference in run-time. Again that’s going to depend on how heavy the rider is, how fast you ride it, how you’re riding, where you’re riding: grass, concrete.

Ultimately, the MX650 does have a little bit longer ride-time than an MX350.

Difference in Voltage

The MX650 has a 36V (three 12V) battery, while the MX350 comes with a 24V (two 12V) battery.

This feature should be important, especially when it comes time to change the batteries because if you buy them from Razor, they can get fairly expensive.

A battery pack for the MX 650 will run you somewhere between $120 and $150. In comparison, a pack for the MX350 will be cheaper for somewhere between $80 and $100.

In terms of motor, there is a 350W motor on the MX350 and a 650W on the MX650.

Difference in Tire Size

The MX350 has 12” front and rear tires so they’re pretty small, whereas the MX650 is set up more like a traditional gasoline-powered dirt bike where it has the larger 16”front tire and the smaller 14-inch rear tire.

Difference in Suspension

The MX650 does have front and rear suspension, which can definitely make a big difference on rougher terrain, whereas the MX350 has a rigid frame with no suspension.

It may be a little safer to have the suspension because it does keep that ground contact of the tire to ground better when it has a suspension, but the MX350 does not have any suspension on it. However, maybe younger kids don’t care about it and will be fine with the MX350.

Difference in Brakes

The MX350 has a single rear brake and works great. Riders will have no problem stopping the bike.

While the MX650 has front and rear disc brakes, which are much better. The front and rear brakes are more like those on a traditional motorcycle.
