* Note on Age: Razor’s recommended age for the MX350 is a highly conservative 13+ but an age range of 5-10 (real world guide from many buyers) with parental supervision may be more suitable. Because this dirt bike is very small – the seat height of 20″ is about 14″ lower than a regular, adult sized dirt bike.

* Note on Age: Razor’s recommended age for the MX650 is 16+ which is also very conservative. An age range of 10-16 (real world guide from many buyers) with parental supervision may be more suitable. Because the seat height of 24″, although higher than the MX350, is still about 10″ lower than an adult sized bike.

Main Differences

The biggest difference between both dirt bikes is the size and age of rider that each was designed for.

The Razor MX650 is the big brother of the MX350 – it has a 20% larger frame, 4″ higher seat, bigger wheels and weighs 36 lbs more. The MX650 supports a heavier rider (220 lbs vs 140 lbs) so is more suitable for teens whereas the MX350 is ideal for kids aged 5-10 years old.

Thanks to a more powerful motor (650W vs 350W) and extra battery (36V vs 24V), the Razor MX650 has a higher top speed (17 mph vs 14 mph) and gives a longer ride per full charge (40 minutes vs 30 minutes). The MX650 also has variable speed and dual suspension whereas the MX350 is single speed with no suspension.

Advantages of Razor MX350 Dirt Rocket

Razor MX350 Dirt Rocket
  • Better height for very young children – the 20″ seat height is 4″ lower than the MX650
  • 20% smaller frame = good size for small children and easier to store or transport
  • 37% lighter (62 lbs vs 98 lbs) = easier for small kids to ride and to lift back up off the ground if it falls over
  • MSRP (Manufacturer’s Suggested Retail Price) is about $250 cheaper than the MX650 – but check the actual prices below

Advantages of Razor MX650 Dirt Rocket

Razor MX650 Dirt Rocket
  • Better size for older kids and teens – the seat is 4″ higher than the MX350 and the frame is 20% larger
  • The Razor MX650 is the fastest Razor electric dirt bike. The more powerful 650W motor gives it a higher top speed (17 mph vs 14 mph for the MX350) and faster acceleration
  • Higher maximum load (220 lbs vs 140 lbs) means it can cope with the weight of teens and even small adults
  • Variable speed = smoother power delivery (MX350 is single speed i.e. on or off which makes the start quite jerky)
  • Dual suspension = better off-roading capability (MX350 has no suspension so the ride is stiff and not forgiving over bumps)
  • Dual disc brakes = better stopping (MX350 has only a single rear brake)
  • Larger wheels = better traction and ride comfort (16″ front / 14″ rear vs 12″ front and rear on the MX350)
  • Longer battery life (40 minutes continuous use vs 30 minutes) so you can have more fun before it runs out of juice

Pros of Both Bikes

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

  • User friendly controls
  • Adjustable angle handlebars can adapt to fast growing kids
  • Fast enough to give an adrenaline rush but slow enough (compared to gas dirt bikes) to minimize risk of a high speed crash
  • Knobby rubber pneumatic tires (unlike plastic tires of cheap bikes and ride on toys) can tackle many ground conditions including some light off-roading
  • Steel frame with authentic motocross frame geometry
  • No pollution (compared to a gas dirt bike)
  • Quieter than a gas dirt bike and requires 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 30 or 40 minutes is still enough to cover 7 or 11 miles respectively
  • Battery full recharge time is up to 12 hours so charging needs to be planned (or you could buy a spare set of batteries to switch over instantly)
  • No reverse gear – can be awkward to maneuver backwards
  • No headlights or rear lights – can only be driven in daylight
  • Not intended for use on public streets
  • Helmet and protective clothing (see our Electric Dirt Bike Buying Guide for recommended safety gear) may be uncomfortable in hot weather
  • Must be stored in a dry area, due to the electrical components
  • Batteries must not be stored in temperatures below freezing and should be recharged at least once a month


The smaller frame and lower seat of the MX350 make it the best choice for very young kids, especially those who are new to dirt bikes. Single speed (simple stop/go) is easier for them to handle and the lack of any suspension won’t make much difference if they rarely go off-road. It’s quick enough to have fun while minimizing the risk of high speed drama.

However, a larger frame, variable speed and bigger tires make the MX650 a better, grown up choice for older kids and teens, especially on rough terrain. With a top speed of 17 mph the MX650 is the fastest model in Razor’s range of electric dirt bikes but it also has better safety features, thanks to dual suspension and dual disc brakes.
