Why the Razor MX350 72V Upgrade Kit is Necessary

When I first got my Razor MX350, I loved the thrill of riding it, but I quickly realized its original power just wasn’t enough for the adventures I wanted.

That’s when I decided to invest in the 72V upgrade kit, and it completely transformed my experience.

With the 72V upgrade, my MX350 gained a noticeable boost in speed and acceleration. I could tackle hills and rougher terrain with much more confidence, something the original setup struggled with. Plus, the improved battery capacity meant longer rides without worrying about running out of power halfway through.

In short, if you want your Razor MX350 to perform at its best and keep up with your riding ambitions, the 72V upgrade kit is absolutely necessary. It’s the difference between a fun ride and an unforgettable one.

My Buying Guides on Razor Mx350 72V Upgrade Kit

When I decided to upgrade my Razor MX350, I quickly realized that choosing the right 72V upgrade kit was crucial to getting the best performance and reliability. If you’re considering the same, here’s what I learned and what helped me make an informed decision.

Why Upgrade to a 72V Kit?

I wanted more speed, longer run time, and better torque from my MX350. The stock 24V system is fun but limited. Upgrading to 72V significantly boosts power, allowing for a more thrilling ride and better handling on hills.

Compatibility with My Razor MX350

First, I made sure the upgrade kit was designed specifically for the Razor MX350 model. Not all 72V kits fit perfectly or work well with the stock components. Look for kits that include instructions or confirmation that they work with the MX350’s motor and frame.

Components Included in the Upgrade Kit

A complete 72V upgrade kit typically includes:

  • Three 24V batteries (to total 72V)
  • A compatible charger
  • Wiring harnesses and connectors
  • Sometimes an upgraded controller

I checked that everything I needed was included or available as add-ons. This saved me from sourcing parts separately and worrying about compatibility.

Battery Type and Quality

The batteries are the heart of the upgrade. I preferred sealed lead-acid batteries for affordability, but some go for lithium-ion for lighter weight and longer life. Make sure the batteries are reliable, have good capacity (Ah rating), and fit securely on your MX350.

Installation Difficulty and Instructions

I’m not a professional mechanic, so clear installation instructions were a must-have. Some kits come with detailed manuals or video tutorials. If you’re like me, look for kits that don’t require complex modifications or specialized tools.

Performance Gains and Real-World Use

Before buying, I read reviews and watched videos to understand what performance gains to expect. A good 72V upgrade kit will noticeably improve speed (often doubling it) and climbing ability. However, keep in mind that increased power may reduce battery run time per charge.

Safety Considerations

Upgrading voltage means extra caution. Make sure the kit includes proper fuses and wiring rated for 72V. I also invested in a good helmet and protective gear since the bike was now much faster.

Price and Value

Prices vary widely. I balanced cost with quality and reliability. Cheaper kits might save money upfront but could lead to problems or extra costs later. I found that spending a bit more for a reputable kit with good customer support was worth it.

Customer Support and Warranty

Having access to customer support helped me troubleshoot during installation. I chose a kit that offered a warranty on batteries and components, which gave me peace of mind.

Final Thoughts

Upgrading my Razor MX350 to 72V transformed my riding experience. By focusing on compatibility, quality components, clear instructions, and safety, I made a purchase I’m happy with. If you’re ready for more speed and power, a 72V upgrade kit is definitely worth considering!
