Razor MX500 vs SX500 Comparison

In this article, we compare the Razor MX500 vs SX500 electric dirt bikes.

Both can be a brilliant choice if you want to treat the young racer in your family to a well specified electric dirt bike. But, although they share almost all the same components, there are some differences between both models.

Our guide below will show you which is the most suitable for your child, or for you! First we’ve got a quick comparison table of the main features of the Razor MX500 vs SX500.

Then we look at the main differences between them and the advantages of each dirt bike, in turn. Finally, we’ll summarize the pros and cons of both rides, to help you make the right choice.

Razor MX500 vs SX500 – Quick Comparison

Both these bikes were our top choice for Overall Best Value when we reviewed the best electric dirt bikes for kids and teens recently. In the table below we’ve summarized the main features of each bike in a side by side comparison.

Note: the only difference in these main features is the type of tires and the design/color – but there are some other differences which we will review in more detail below the table.

* Age: Razor’s recommended age for both these bikes is 14+ but this is extremely conservative. An age range of 8-14 (real world guide from many buyers) with parental supervision may be more suitable. Because these bikes aren’t an adult size – the seat height is about 24″, compared to 34″ or more on a regular adult dirt bike.

Main Differences

As the table above shows, both models are mechanically and electrically the same bike with the same size frame.

The biggest difference between both models is that the Razor SX500 has authentic Jeremy McGrath (the ‘King of Supercross’) graphics and fairings. It also has “motorcycle-spec” tires which appear to be a little harder compound than those on the regular MX500, so they may last longer.

The SX500 is also a current model whereas the venerable MX500 is no longer in production, according to Razor’s website (although it is still available from online sellers). The SX500 is also green with gray detail whereas the MX500 is orange with black detail.

The video below shows the Razor SX500 Dirt Rocket McGrath in action:

Advantages of Razor MX500 Dirt Rocket

Both these bikes are so similar in specification that there aren’t many advantages compared to the SX500:

  • MSRP (Manufacturer’s Suggested Retail Price) was about $10 cheaper than the SX500 – but check the actual prices below
  • Some people may prefer the orange and black color scheme

Likewise, the SX500 doesn’t have too many advantages over the regular MX500:

  • Motorcycle-spec tires may last slightly longer than those on the MX500
  • The SX500 is a current model
  • It’s a personal preference but we think the McGrath branding and decals look better than the orange and black style of the MX500

Pros of Both Bikes

Here is a summary of what we love about both models:

  • Specifically designed for older kids or teens
  • User friendly controls
  • Adjustable angle handlebars can adapt to fast growing kids (longer legs)
  • Quick enough to give an adrenaline rush
  • Slow enough (compared to gas dirt bikes) to minimize risk of a high speed crash
  • Large knobby rubber pneumatic tires can tackle many ground conditions, including off-road
  • Dual suspension and dual brakes provide better safety and comfort when off-roading
  • Steel frame with authentic motocross frame geometry
  • No pollution (compared to a gas dirt bike)
  • Quieter and cheaper than a gas dirt bike
  • Requires much less servicing than a gas dirt bike
  • Razor is a long established US manufacturer – spare or replacement parts are readily available from their website

Cons of Both Bikes

Here is a summary of what we don’t like so much about both models. But most of these issues are common to all electric dirt bikes in this price range:

  • Relatively short battery life. But 40 minutes is still enough to cover 10 miles
  • Battery full recharge time is up to 12 hours so charging needs to be planned
  • The seat height of 24″ may be too low for tall teens (and many adults)
  • No headlights or rear lights – can only be driven in daylight
  • Helmet and protective clothing (see our Electric Dirt Bike Guide for recommended safety gear) may be uncomfortable in hot weather
  • Not as high top speed as many gas dirt bikes
  • Must be stored in a dry area, due to the electrical components
  • Batteries must not be stored in temperatures below freezing and must be recharged at least once a month


Both these dirt bikes are a great choice for older kids and early teens. But they are so similar that it is tough to pick a winner between them.

So which model is best? Unless you prefer a particular color then the ideal choice depends mostly on price and availability.

The MX500 is still available to buy online but appears to have ceased production – it no longer appears on Razor’s website, although they still sell replacement parts for it.

Therefore we’d choose the SX500 as it is the newer (and current) model with slightly better tires and we think it has a cooler, more grown up, look.

Owner’s Manual

As the Razor MX500 Dirt Rocket and SX500 Dirt Rocket McGrath are so similar they share the same owner’s manual – it is available in PDF format from Razor here.

NOTE: A parent’s decision to allow their child to ride either the Razor MX500 or the Razor SX500 should depend on the child’s individual maturity, skill and ability to follow rules.
