Razor MX350 vs MX650: What’s the Difference?

The Razor MX350 and Razor MX650 may look like similar scaled-down electric dirt bikes, but they are built for very different riders.

The MX350 is the smaller and slower model, designed as an entry point into electric dirt-bike-style riding. The MX650 is substantially larger, more powerful, and better equipped, with bigger wheels, full suspension, dual disc brakes, and a higher rider-weight limit.

The biggest differences come down to:

• Motor power;
• Top speed;
• Battery size;
• Wheel size;
• Suspension;
• Braking;
• Rider size;
• Price.

If you're deciding between the Razor MX350 and MX650, this guide explains what those differences mean in real-world use.

Razor MX350 vs MX650: Quick Comparison

Razor's current U.S. MX350 page lists a 250W motor, 24V sealed lead-acid battery, 10 mph Low mode, 14 mph High mode, and a 140 lb maximum rider weight.

The MX650 uses a 650W motor with a 36V battery system, reaches up to 17 mph, supports up to 220 lb, and uses 16"/14" wheels with front and rear suspension and dual disc brakes.

*Prices can change. Razor's U.S. shop currently lists the MX350 at $349.99 and MX650 at $849.99.

Motor Power: 250W vs 650W

One detail worth clarifying is the MX350's name.

Despite being called the MX350, Razor's current documentation lists its motor as:

24V / 250W

The MX650 uses:

36V / 650W.

That means the MX650 has considerably more motor output available.

Razor MX350

The lower-powered motor suits:

• Learning basic throttle control;
• Flat private-property riding;
• Light dirt riding;
• Smaller riders.

Razor MX650

The 650W motor provides more capability for:

• Heavier riders;
• Hills;
• Dirt;
• Faster acceleration.

However, the MX650 is still very different from today's multi-kilowatt electric dirt bikes.

A 650W Razor and a 3000W–3500W electric dirt bike belong to very different performance categories.

Top Speed: 14 mph vs 17 mph

The MX350 reaches:

Up to 14 mph in High mode

and:

Up to 10 mph in Low mode.

Razor says its current MX350 includes a parent-controlled High/Low speed setting.

The MX650 reaches:

Up to 17 mph.

On paper, three miles per hour may not sound like a huge difference.

But rider size and bike size also change.

The MX650 has:

• More power;
• Larger wheels;
• More weight;
• More capable suspension.

So it feels like a significantly larger dirt bike rather than simply a slightly faster MX350.

MX350 Speed Modes

This is an important feature of the current MX350.

Razor lists:

Low Speed Mode

• Up to 10 mph;
• Up to 60 minutes continuous use.

High Speed Mode

• Up to 14 mph;
• Up to 30 minutes continuous use.

The speed-control switch is located behind a cover and requires a tool to access, allowing a parent or responsible adult to select the appropriate maximum speed.

This makes the current MX350 more adaptable for riders still learning basic controls.

Battery: 24V vs 36V

The MX350 uses two 12V 7Ah sealed lead-acid batteries wired as a 24V system.

That gives approximately:

24V × 7Ah = 168Wh

of nominal energy.

The MX650 manual lists three 12V 12Ah batteries, creating a 36V system.

That works out to approximately:

36V × 12Ah = 432Wh

So the MX650 has well over twice the nominal stored battery energy.

That larger battery is needed because it also has:

• More motor power;
• More bike weight;
• Larger wheels;
• Higher performance.

Both Use Sealed Lead-Acid Batteries

Neither model uses the type of lithium-ion battery common on many newer electric dirt bikes.

Both rely on sealed lead-acid batteries.

Lead-acid batteries are:

• Proven;
• Relatively simple;
• Widely available.

But compared with lithium-ion packs, they tend to be:

• Heavier for the same usable energy;
• Bulkier;
• Less energy-dense.

This partly explains why the MX650 weighs around 95 lb despite having only a 650W motor.

Runtime: Which One Lasts Longer?

The MX350 is rated for:

Up to 60 minutes in Low mode

or:

Up to 30 minutes in High mode.

The MX650 is rated for:

Up to 40 minutes of continuous use.

These figures are runtime rather than mileage.

Actual ride time will vary with:

• Rider weight;
• Hills;
• Throttle use;
• Terrain;
• Battery condition;
• Tire pressure.

Because neither model is designed around long-distance riding, they make more sense for relatively short recreational sessions than long trail rides.

Wheel Size: 12"/12" vs 16"/14"

This is one of the biggest physical differences.

Razor MX350

The MX350 uses:

12-inch front and rear wheels.

This creates a very compact bike.

Razor MX650

The MX650 uses:

16-inch front / 14-inch rear wheels.

Larger wheels generally make it easier to roll over:

• Small rocks;
• Ruts;
• Roots;
• Rough dirt.

The MX650 therefore provides a much more dirt-bike-like platform for larger riders.

Suspension: Major Advantage for the MX650

The MX350 has a double-crown steel front fork, but Razor does not list a conventional front-and-rear suspension system for it.

The MX650 includes:

Front and rear suspension.

That matters as terrain gets rougher.

Suspension helps:

• Maintain tire contact;
• Absorb bumps;
• Improve comfort;
• Improve control.

For casual flat-ground riding, the MX350's simpler chassis may be sufficient.

For actual uneven dirt terrain, the MX650 provides a much more capable foundation.

Brakes: Rear Brake vs Dual Disc Brakes

The MX350 uses:

A hand-operated rear brake.

The MX650 uses:

Hand-operated front and rear disc brakes.

This is another substantial upgrade.

Because the MX650 is:

• Faster;
• Heavier;
• Designed for larger riders;

having braking force available at both wheels becomes much more important.

Rider Weight: 140 lb vs 220 lb

The MX350 supports riders up to:

140 lb.

The MX650 supports riders up to:

220 lb.

This difference alone can determine which bike is appropriate.

A rider may technically be old enough for an MX350 but too heavy or physically too large for its compact chassis.

Age is therefore only one part of the decision.

MX350 vs MX650 Age Recommendations

Razor currently lists the MX350 for:

8+ in Low Speed Mode and 13+ in High Speed Mode.

The MX650 is listed for:

Age 16+.

These are manufacturer's age recommendations rather than guarantees that every rider of that age will fit the bike.

Rider suitability also depends on:

• Height;
• Weight;
• Strength;
• Riding experience;
• Ability to control the bike.

For broader guidance, see our Best Electric Dirt Bikes for Teens Guide.

Size and Weight

The MX350 weighs approximately:

48 lb

while the MX650 is around:

94–95 lb.

So the MX650 is almost twice as heavy.

That makes the MX350 easier to:

• Move around manually;
• Load into a vehicle;
• Handle at low speed.

But the MX650's additional weight comes with a much larger:

• Frame;
• Battery;
• Motor;
• Wheel setup;
• Suspension system.

A lighter bike is not automatically the better choice if the rider has already outgrown it.

Price Difference

Razor's current U.S. store listings show approximately:

MX350: $349.99

and:

MX650: $849.99.

So moving to the MX650 requires a substantial increase in budget.

For that additional cost, buyers receive:

• 650W vs 250W motor;
• 36V vs 24V battery;
• Larger wheels;
• Front and rear suspension;
• Dual disc brakes;
• Higher load capacity;
• Larger frame.

For a rider who physically fits the MX350 and only needs low-speed riding, the additional hardware may not be necessary.

For larger riders, the MX650 is a very different machine rather than simply a premium version of the same small bike.

Which Is Better for a Beginner?

For a smaller new rider, the MX350's:

• Lower top speed;
• Low-speed mode;
• Lower bike weight;
• Smaller wheels;

can make it easier to approach.

The MX650 provides substantially more size and weight.

But an older or larger beginner may physically fit the MX650 better even if they have less riding experience.

So beginner suitability should be judged by both:

Experience + physical fit

rather than experience alone.

Which Is Better for Dirt Trails?

For rougher terrain, the MX650 has several clear hardware advantages:

• 16"/14" wheels;
• Front and rear suspension;
• Dual disc brakes;
• Larger chassis;
• More motor power.

The MX350 makes more sense for:

• Flatter dirt;
• Grass;
• Smooth private property;
• Introductory riding.

Neither should be confused with a full-size motocross bike.

Which Is Better for Hills?

The MX650 is specifically positioned by Razor as having more power for uphill and off-road conditions.

Its advantages include:

• 650W motor;
• 36V battery;
• Larger chassis.

The MX350's 250W motor is much more modest.

For steep hills or heavier riders, expectations should therefore remain limited.

Is the Razor MX650 Fast?

Compared with the MX350, yes.

Compared with modern higher-powered electric dirt bikes, no.

The MX650 reaches around:

17 mph

while many newer compact electric dirt bikes can reach:

• 25 mph;
• 30 mph;
• 35 mph;
• Or higher.

This is important because someone searching for an MX650 may actually be looking for one of two things:

1. A moderate-speed Razor recreational bike; or
2. A stepping stone toward a more powerful electric dirt bike.

Those are different buying needs.

When Might a Rider Outgrow the MX350?

A rider may be ready to move beyond the MX350 when:

• They exceed or approach the 140 lb limit;
• The 12" wheels feel too small;
• 14 mph feels limiting;
• They want suspension;
• They need stronger brakes;
• They ride rougher terrain.

The MX650 solves many of those issues.

But some riders may quickly find that even 17 mph and 650W are still below what they want.

When Might a Rider Outgrow the MX650?

The MX650 can be a useful recreational step up, but riders looking for significantly more performance may eventually want:

• Lithium-ion batteries;
• Multi-kilowatt motors;
• Longer range;
• Higher top speed;
• More ground clearance.

That is where a bike such as the BUFFSEEK R01 enters a different category.

For a direct comparison, see our BUFFSEEK R01 vs Razor MX650 Guide.

Razor MX650 vs BUFFSEEK R01: The Next Step Up

The difference is substantial:

Check 3500W Electric Dirt Bike Guide to learn more.

This is not a small upgrade.

Moving from the MX650 to an R01-class bike means moving from a moderate-speed recreational Razor into a substantially higher-power electric dirt bike.

For that reason, rider experience becomes increasingly important.

Which One Should You Choose?

Consider the Razor MX350 if:

• The rider is smaller;
• Low-speed riding is the priority;
• You want a lighter bike;
• 10–14 mph is enough;
• You want the lower-cost option;
• The rider is learning basic throttle control.

Consider the Razor MX650 if:

• The rider needs a larger chassis;
• The rider weighs more than the MX350 limit;
• You want front and rear suspension;
• You want dual disc brakes;
• You want larger 16"/14" wheels;
• 17 mph is sufficient.

Consider Moving Beyond the MX650 if:

• You want 30+ mph performance;
• You want a lithium battery;
• You want substantially more range;
• You need multi-kilowatt power;
• You are looking for a more capable compact electric dirt bike.

In that case, compare the MX650 with bikes such as the BUFFSEEK R01 rather than assuming the next Razor size is the only option.

Final Comparison

The Razor MX350 and MX650 are designed for different stages of riding.

The MX350 focuses on:

Smaller size + lower speed + lighter weight + lower price

while the MX650 moves toward:

Larger wheels + more power + suspension + stronger brakes + higher rider capacity

For riders just getting started, the MX350 provides a much gentler introduction.

For larger riders who still want moderate recreational performance, the MX650 offers a substantial hardware upgrade.

And once a rider begins looking beyond the MX650's 650W motor and 17 mph top speed, it may make more sense to compare higher-powered lithium electric dirt bikes rather than simply looking for another small step up.
