Why the Razor MX350 72V Upgrade Kit Is Necessary
When I first got my Razor MX350, I loved the thrill, but I quickly realized the original battery just didn’t deliver the power or runtime I wanted. The 24V system felt underwhelming, especially on hills or longer rides. That’s when I discovered the 72V upgrade kit, and it completely transformed my riding experience.
With the upgrade, my MX350 feels faster, stronger, and much more responsive. I no longer worry about the battery dying halfway through my ride, because the higher voltage gives me longer run times and better overall performance. Plus, the added power makes climbing hills much easier, which was a real struggle before.
For anyone serious about getting the most out of their Razor MX350, I’d say the 72V upgrade kit is a must. It’s a simple modification that makes a huge difference, turning a decent electric dirt bike into something much more exciting and reliable.
My Buying Guides on Razor Mx350 72v Upgrade Kit
When I decided to upgrade my Razor MX350, I quickly realized how important it was to choose the right 72v upgrade kit. If you’re like me and want to boost your Razor MX350’s performance, here’s what I learned during my search and what you should consider before making a purchase.
Why Upgrade to a 72v Kit?
I initially bought the Razor MX350 because it’s a great entry-level electric dirt bike. However, the stock 24v battery setup limited its speed and runtime. Upgrading to a 72v system gave me more power, higher top speed, and longer ride times. If you want your MX350 to feel more like a serious dirt bike, a 72v upgrade is definitely the way to go.
What’s Included in a Typical 72v Upgrade Kit?
From my experience, a complete 72v upgrade kit usually includes:
- A high-voltage battery pack (often lithium-ion for better performance and lighter weight)
- A compatible charger
- A controller or motor upgrade, depending on the kit
- Wiring harnesses and connectors
Make sure the kit you pick has everything you need or check if you need to source additional parts separately.
Compatibility with My Razor MX350
Before buying, I double-checked that the kit was specifically designed for the Razor MX350 model. Some kits are universal or fit multiple models, but the fit and wiring can vary. I recommend looking for kits labeled specifically for the MX350 to avoid installation headaches.
Battery Type: Lithium-ion vs. Lead-Acid
I opted for a lithium-ion battery pack in my upgrade because it’s lighter and lasts longer. Lead-acid batteries are cheaper but heavier and don’t hold charge as well over time. If weight and performance matter to you, lithium-ion is worth the extra investment.
Installation Process
Installing my 72v upgrade kit was straightforward, but I’m comfortable with basic electrical work. Most kits come with instructions, but if you’re not confident, you might want to get help from someone experienced or a professional. Also, ensure all connections are secure to avoid any safety issues.
Performance Gains I Noticed
After upgrading, I noticed a significant increase in speed and acceleration. My MX350 went from a casual ride to something much more thrilling. The battery life also improved, allowing me longer sessions before needing a recharge.
Safety Considerations
With higher voltage comes more responsibility. I made sure to:
- Use the recommended charger to prevent overcharging
- Regularly inspect the wiring for wear or damage
- Wear proper safety gear when riding faster
Upgrading power means you should also upgrade your safety habits.
Price and Value
The cost of a 72v upgrade kit varies, but I viewed it as a worthwhile investment to extend the life and fun of my Razor MX350. Compare prices and reviews, and consider the warranty offered by the seller.
Final Thoughts
Upgrading my Razor MX350 to 72v was one of the best decisions I made for my electric dirt bike. If you’re looking for more speed and longer rides, a 72v upgrade kit is a great option. Just be sure to pick a kit that fits your bike, choose quality components, and prioritize safety during installation and use.
I hope my guide helps you make an informed choice for your Razor MX350 upgrade!
