Why I Believe the Razor Mx350 72V Upgrade Kit is a Necessity

As someone who has been an avid rider of the Razor Mx350 electric dirt bike for years, I can confidently say that the 72V upgrade kit is an absolute necessity. Let me explain why.

First and foremost, the stock 24V battery on the Razor Mx350 just doesn’t cut it for those who are serious about riding. It’s great for beginners or younger riders, but as you become more experienced and want to push the limits of your bike, you’ll quickly realize that more power is needed. That’s where the 72V upgrade comes in.

With this kit, you’ll get a significant boost in power and speed. The stock 15mph top speed will be increased to a whopping 35mph, making it much more suitable for off-road adventures and adrenaline-fueled rides. Not only that, but you’ll also experience improved acceleration and torque, allowing you to tackle steeper inclines and rougher terrain with ease.

Another reason why this upgrade is necessary is the extended ride time it provides. With a larger battery capacity, you’ll be able to ride for longer periods without having to stop and recharge.
