* Note on 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 both bikes are quite small – the Razor SX500 seat height is only 24″ – that’s at least 10″ lower than a regular adult size dirt bike.

Main Differences

The Razor MX500 and SX500 are mechanically and electrically the same dirt bike with the same size frame. The biggest difference is that the SX500 has Jeremy McGrath (the ‘King of Supercross’) graphics and fairings. It also has motorcycle-spec tires which are a harder compound than those on the MX500.

The SX500 is green with gray detail whereas the MX500 is orange with black detail. The SX500 is a current model whereas the MX500 is discontinued, according to Razor’s website (although it is still available from online sellers).

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) is $10 cheaper than the SX500 – but check the actual prices below
  • Some people may prefer the orange and black color scheme

Advantages of Razor SX500 Dirt Rocket McGrath

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

  • Motorcycle-spec tires may last longer than the standard tires on the MX500
  • The SX500 is a current model whereas the MX500 is discontinued
  • It’s a personal preference but we think the green color with McGrath branding and decals looks more grown up and modern 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 with user friendly controls
  • Adjustable angle handlebars can adapt to fast growing kids (longer legs)
  • Quick enough to give an adrenaline rush but 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-road
  • Steel frame with authentic motocross frame geometry
  • No pollution (compared to a gas dirt bike)
  • Quieter and cheaper than a gas dirt bike and require much less servicing
  • 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, or you could buy a spare set of batteries for an instant change over
  • The seat height of 24″ may be too low for tall teens and adults
  • No headlights or rear lights – can only be driven in daylight
  • Helmet and protective clothing may be uncomfortable in hot weather (see our Electric Dirt Bike Guide for recommended safety gear)
  • 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 no longer appears on Razor’s website, although they (and many other shops) still sell spares and replacement parts for it.

Therefore, if the prices were the same, we’d choose the SX500 as it is the newer, 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 dirt bike should depend on the child’s individual maturity, skill and ability to follow rules.
