My Buying Guides on Mx350 Razor Upgrade Kit
When I decided to upgrade my MX350 Razor, I realized there are several important factors to consider to get the best performance and value. Here’s what I learned and what I recommend keeping in mind if you’re looking for an upgrade kit.
Understanding What the MX350 Razor Upgrade Kit Includes
Before buying, I made sure to check exactly what parts are included in the upgrade kit. Some kits come with essential components like new wheels, suspension parts, or motor upgrades, while others might be more basic. Knowing what’s included helps avoid buying extra parts separately.
Compatibility with My MX350 Model
I double-checked that the upgrade kit was fully compatible with my MX350 Razor model. Since there are different versions and years of the MX350, compatibility can vary. Trying to fit parts that aren’t meant for your specific model can cause issues or even damage.
Performance Improvements I Was Looking For
For me, the main goal was to improve speed, handling, and battery life. So I looked for upgrade kits that included a higher torque motor, better battery options, or enhanced suspension components. Consider what performance aspects matter most to you—speed, durability, or ride comfort.
Quality and Brand Reputation
I researched brands and read reviews to find upgrade kits made from quality materials. A poorly made kit can wear out fast or not fit properly. Choosing a reputable brand gave me confidence that the upgrades would last and perform well.
Ease of Installation
Since I’m not a professional mechanic, I wanted a kit that was straightforward to install with clear instructions. Some kits require advanced tools or technical know-how, while others are designed for easy DIY upgrades. Decide how much work you’re willing to do yourself.
Price vs. Value
Upgrading my MX350 was an investment, so I compared prices of different kits and what they offered. Sometimes spending a bit more upfront can save money later by avoiding frequent replacements or additional purchases.
Customer Support and Warranty
It helped to check if the seller or manufacturer offered good customer support and a warranty. This way, if anything went wrong during installation or if a part was defective, I could get help or a replacement without hassle.
Additional Accessories and Future Upgrades
Finally, I considered whether the upgrade kit allowed for further modifications down the line. Some kits are modular and can be combined with other accessories, giving me room to customize my MX350 Razor even more in the future.

I hope my experience and these points help you choose the right MX350 Razor upgrade kit for your needs. Happy riding!
