Small upgrades gave me a big difference for a low cost, which made the bike feel more worth keeping and riding.
I also realized that cheap upgrades helped me fix the things I was not happy with. My MX350 felt a little limited in stock form, especially when it came to speed, comfort, and battery life.

For me, cheap upgrades were not just about saving money—they were about getting better value, improving the riding experience, and making the bike feel more personal.
My Buying Guides on Razor Mx350 Cheap Upgrades
Why I Look for Cheap Upgrades First
When I think about improving a Razor MX350, I always start with the low-cost upgrades. I’ve found that small changes can make a big difference without forcing me to spend a lot of money.

What I Focus on Before Buying Anything
Before I order any upgrade, I check a few things first:
- Compatibility: I make sure the part fits the MX350.
- Budget: I compare prices so I don’t overspend.
- Purpose: I decide whether I want more speed, better handling, or longer riding time.
- Ease of installation: I prefer upgrades I can install myself.
Cheap Upgrades I Think Are Worth It
1. Better Tires
One of the first upgrades I consider is better tires. I’ve noticed that improved tires can give me better grip and a smoother ride, especially on dirt or uneven ground. If I ride often, this is one of the smartest low-cost improvements I can make.
2. Throttle Upgrade
A throttle upgrade can make the bike feel more responsive. I like this upgrade because it can improve control without being too expensive. It’s a practical choice if I want a better riding experience.
3. Chain and Sprocket Adjustments
When I want a little more performance, I look at the chain and sprocket setup. I’ve found that changing sprocket sizes can help with acceleration or top speed, depending on what I want. This is one of the most budget-friendly ways to tweak the MX350.
4. Battery Upgrade Options
If I want longer ride time, I look into battery upgrades. I know this can cost more than some other upgrades, but I still consider it a cheap upgrade if I choose carefully. A better battery can make the bike much more enjoyable, especially for longer rides.

- Will this upgrade improve safety?
- Is the price worth the result?
- Can I install it myself?
For me, the best cheap upgrade is the one that solves the biggest problem first.
What I Avoid When Shopping
