Why Upgrade Razor Dirt Bikes

Why Upgrade Razor Dirt Bikes

The Razor Dirt Bikes are already one of the best electric dirt bikes for kids, due to their performance. Right out of the box, the Razor MX650 offers a 36v battery and a 650w motor that allows for speeds up to 17 MPH with around 40 minutes of ride time. For an absolute beginner, this may get the job done. If you’re like me, upgrading a Razor dirt bike is going to be one of the first things I do after purchasing one. The battery, motor, suspension, and brakes are all things that will see great benefits from being upgraded.

“I personally owned a Razor MX350 as a child and it was the perfect toy for when I had that itch to ride, but getting my dirt bike out of the garage wasn’t a possibility.” States Ryan Dragunas, who also tested the Razor MX650. “However, one problem I always had with the razor was that it was a bit too slow for my likings and there was no way to upgrade razor dirt bikes back then.”

Safety Precautions Before Upgrading

Before upgrading the Razor dirt bike, ensure safety by having the proper safety gear. Verify that any issues with the dirt bike have been resolved prior to upgrading. If you are installing the upgrades yourself, make sure that you have the proper tools and a well-lit working area.

How to Upgrade Razor Dirt Bikes: Step-by-Step Guide

Step 1: Upgrading the Battery & Motor

Upgrading the Battery & Motor

When upgrading Razor dirt bikes, there are a few battery & motor kits on the market for the Razor, but I highly recommend the Electro & Co. 5,000w kit or 11,000w kit. Electro & Co. is a leader in the market, making drop-in kits for various dirt bikes, big and small.

The 11,000w kit includes an upgraded battery, motor, controller, and MX throttle with a 3-mode switch. A handlebar mounted power switch, volt meter, and included MX grips increase the ease of use and control.

With the 5,000w kit, you’ll get a slightly less powerful battery, motor, and controller. Just like the other kit, a new MX throttle is used, as well as included MX grips and a handlebar-mounted power switch.

You can expect speeds of 50MPH or 60+MPH with different gearing on the 11,000w kit and 2-4 hours of ride time. Speeds of 45+MPH are possible with different gearing on the 5,000w kit with ride times at 2-4 hours.

Step 2: Enhancing Suspension System

Enhancing Suspension System

If you want more than speed, upgrading the suspension is another great enhancement that is now possible on the Razor electric dirt bikes.

For the front forks, I recommend going with the ETM Hydraulic Fork upgrade. These beefy motocross forks come in a kit that allow for direct bolt-on fitment. The kit replaces the stock handlebars, bar mounts, triple trees, forks, front wheel, wheel hardware, front fender, and other bits and pieces.

For the rear shock, you’ll want to upgrade to match the new performance of the front forks. I recommend the DNM rear shock upgrade. This shock pairs with the ETM Front Fork upgrade and also provides adjustable rebound and dampening. The ETM Front Fork kit update for Razor and the DNM rear shock.

Step 3: Improving Braking Performance

Improving Braking Performance

While the MX650 already features disc brakes, I highly recommend upgrading to hydraulic disc brakes.

With a dirt bike that is capable of going 50 MPH or faster, it is absolutely crucial that you can stop on time to avoid injury. There are multiple options for upgrading to hydraulic set ups on the Razor. Just like the other upgrades, Electro and Co. has an option for this.

If you’re looking for a lower-cost setup, there are options that can be found on Amazon such as the Zoom Hydraulic Disc Brake Set. Just keep in mind that kits like these are more of a universal type of kit, so be sure to research any modifications or special tools needed before purchasing.

Step 4: Upgrading Tires and Wheels

Upgrading Tires and Wheels

For wheels, you can usually get away with running the stock wheels to save some money.

If you upgrade to one of the higher power kits, it may be a good idea to install wheels that are slightly bigger. This will make the dirt bike easier to control, and the rear wheel will spin less which means better traction.

For tires, this will depend on the type of riding you do.

  • If you strictly ride off-road, I recommend an aggressive knobby tire from reputable brands such as Dunlop, Pirelli, Maxxis, Michelin, Etc.
  • If you ride supermoto or mainly on paved surfaces, I’d recommend a street tire such as the Kenda KM1 or the Continental Conti Tour.
  • Consider “Dual Sport” tires, which give decent traction on paved surfaces and off-road. A good example of these tires are the Kenda K760 Trakmaster Dual Sport or the Dunlop D605 Dual Sport tires.

Must-Have Accessories for Razor Dirt Bike Enthusiasts

Protective Gear

As with any dirt bike, safety should be the top priority. Before upgrading your Razor dirt bike, ensure that you have the proper riding equipment to keep you safe in the event of a crash or fall. Things like a DOT-approved helmet, goggles, gloves, knee-pads, elbow-pads, durable pants/jerseys, and chest protectors are all pieces of gear that you should be using at minimum.

Additional Add-ons

Aside from the upgrades mentioned above, there are other ways to upgrade your Razor dirt bike to elevate your riding experience or add a bit of flair to your electric dirt bike. Things like pivot levers, handlebars, seats, and grips can all be changed out for a unique feel. Plastics, graphics, and rim colors can all be modified to add a personal touch.


By upgrading your Razor dirt bike, you can not only save money but also take your rides to a thrilling new level all while staying silent and looking out for the environment. Consider the different points made above and choose the right upgrades to build a dirt bike that truly compliments your style!
