Customer Review: “My favorite part is the electric start, it gets around trails perfectly and can handle some basic offroad ATV terrain. The bike sounds great and wasnt hard to put together especially if you follow along to a youtube video with a guy with a british accent. Ive owned it a week and been on it 3 times already.

Customer Reviews
Customer Review: “5 Stars! My son and I made a video of how the bike has worked out for him so far, we just posted it today on YouTube. The file is too big to upload here. If you search ‘Owen Westlund Mototec X2 110cc’ you should see it. I wanted to get my son a bike, normally i’d find something locally that needs work but we’ve got plenty of projects in the garage already and I didn’t need another. I also wanted a 4 stroke so he wouldn’t have to mix gas (or risk running straight gas through it!) and ideally wanted electric start. We ride ATVs together often, and now bikes. I didn’t want him to stall the bike or foul a plug on a hot day and have to kick it 20 times like the things i grew up on. It was packed very well, and arrived with zero damage or missing parts. That’s sometimes the hardest part about buying these types of things online: When the item weighs over 100 pounds it’s easy for it to get beat up in shipping. We put it together in no time, most of the components only go on one way. If you haven’t put a bike together before, just go slow and you’ll be fine. Throttle cable needed some adjustment, it was holding the bike at a higher RPM than it needed to be. Not a big deal, you’ll have that on most things like this. He’s got about 30 hours on it so far, we’ve driven bikes together quite a bit this summer and it always starts and hasn’t let us down at all! Check out the video we made if you’d like to see how it looks and how it runs, we’ve got some driving footage in there as well. This review may sound sponsored. It’s not. I paid for it entirely and received nothing from the company. I almost never post reviews on here. If you’re a parent trying to find something decent that isn’t a beat-up facebook marketplace bike like I was, i recommend it!” – OwenW
Customer Review: “We ordered and received the bike. After we put it together it ran for about an hour and then quit. Throttle cable and electric start was damaged during shipping. Called the seller and after several weeks of back and forth with no real support besides sending us a new cable. Seller sent me to the manufacturer who was HORRIBLE. They told us that because of the price of the bike, they would email us how to fix if possible but there was no way to have someone come look at the bike and repair. It was up to us to fix ourselves. They do not take phone calls so you have to email only! Do not buy this unless you want to fix it all on your own.” – FrustratedDad

Complete Buying Guide for Best Gas for Dirt Bike
Essential Factors We Consider
When recommending the best gas for your dirt bike, we look at several key factors. First and foremost is the octane rating, which is critical for preventing engine knock or pinging, especially in high-compression engines common in dirt bikes. We also consider the type of fuel – whether it’s standard unleaded, premium, or specialized racing fuel, ensuring it matches your bike’s specific requirements. Ethanol content is another crucial aspect; many dirt bike engines are not designed to handle high ethanol levels, which can degrade fuel lines and seals. Finally, we assess the availability and cost, aiming for options that offer good performance without breaking the bank.
Budget Planning
Fuel costs can add up, especially if you ride frequently. While high-performance racing fuels might offer marginal gains for professional riders, they come with a significantly higher price tag. For most recreational dirt bike riders, using a high-quality regular unleaded gasoline (if your bike is designed for it and contains minimal to no ethanol) or a premium unleaded gasoline with a lower ethanol content is usually the most cost-effective solution. Always consult your owner’s manual to determine the minimum octane requirement. Investing in a fuel stabilizer can also help preserve fuel during storage, saving you money on replacing old, degraded gas.
Final Thoughts
Ultimately, the best gas for your dirt bike is the one recommended by the manufacturer and suited to your riding conditions. Sticking to the recommended octane rating and minimizing ethanol content will help ensure your engine runs smoothly and lasts longer. Don’t overlook the simple steps like using a fuel stabilizer; they can save you headaches and money in the long run.
Frequently Asked Questions
Q: What is the best octane rating for dirt bikes?
A: Most dirt bikes recommend using regular unleaded gasoline with an octane rating of 87 or 89. However, high-performance or high-compression engines might require premium fuel with an octane rating of 91 or higher. Always check your owner’s manual for the specific recommendation for your bike model.
Q: Is ethanol bad for dirt bikes?
A: Yes, ethanol can be detrimental to dirt bike fuel systems. Many dirt bike components, especially older ones, are not designed to withstand the corrosive properties of ethanol. High ethanol content can degrade fuel lines, seals, and other parts, leading to leaks and engine damage. It’s best to use ethanol-free gasoline or fuels with the lowest possible ethanol content (typically E10 is the maximum acceptable for most bikes).
Q: Can I use racing fuel in my dirt bike?
A: While racing fuels offer higher octane ratings and specialized additives, they are usually unnecessary for recreational dirt bike riding. Using racing fuel in a bike not designed for it can sometimes lead to performance issues or even damage due to different burn characteristics. Stick to the manufacturer’s recommendations unless you are a professional racer with specific tuning needs.
Q: How important is fuel freshness for dirt bikes?
A: Fuel freshness is very important. Gasoline degrades over time, especially when exposed to air and heat. Stale fuel can lead to hard starting, poor performance, and engine issues. If your bike will be stored for more than a month, it’s highly recommended to use a fuel stabilizer or drain the fuel system.
Q: What is the difference between 2-stroke and 4-stroke gas requirements?
A: 2-stroke dirt bikes require a mixture of gasoline and specific 2-stroke oil. The gas itself is typically a standard unleaded type, but the oil ratio is critical. 4-stroke dirt bikes use straight gasoline, similar to cars, and the primary concern is the octane rating and ethanol content, not mixing oil with the fuel.
Choosing the right gas for your dirt bike is a fundamental aspect of maintenance that directly impacts performance and engine health. By understanding octane ratings, ethanol content, and your bike’s specific needs, you can ensure a smoother, more powerful, and reliable ride. Always refer to your owner’s manual for precise fuel recommendations. If you’re looking for a new dirt bike to hit the trails with, check out our top picks above!
