These space the Fastest stock ATVs You have the right to Buy

Here space the fastest stock ATV optimal speeds for comparison. They are the faster 4 wheeler optimal speeds together reported through the world and/or establishments listed. If no company or person is noted I included the surname of the website who available plausible tape-recorded speeds with video clip evidence.

I execute not introduce speeding also if just to uncover out what your ATV’s peak speed is, that’s why we have the internet. Now onto the stock ATV height speed reports:


In 2001: BRP announced that their year old share DS650 ATV was qualified of reaching a height speed the 75-77MPHIn 2004: Dirtwheels magazine reported that during testing they clocked a stock Yamaha YFZ 450r at a height speed that 75MPHIn 2008: Polaris joined the rate fray through their share Outlaw 525S ATV at approximately 75MPHIn 2010: Arctic Cat carried their Behemoth 1000cc stock Thundercat ATV come a optimal stock speed of 79MPH which, considering it is a energy ATV and also not a sport ATV, is pretty impressive.In 2016: Yamaha’s YFZ 450 taped a stock height speed the 75MPH at a Texas raceway.A stock KFX 400 peak speed ideologies 69MPH according to several civilization who contacted me directly.

I was recently asked how rapid a Kawasaki KFX 400 ATV could go and also from memory ns answered somewhere in the 65MPH range. ATV age, altitude, after-market parts, terrain form and general problem play an essential role in determining top speed.

I asked on Twitter and also searched a couple of of my favourite hot-spots to uncover that others have actually topped out at roughly the 68-70MPH variety on their KFX 400’s. Ns don’t recommend trying it you yourself on a provided ATV, particularly if local laws prohibit girlfriend from riding on roads, but I did discover a video clip of what that could look like to reach optimal speed ~ above a KFX 400, take a look.

If you own one, and have already found out an initial hand, I’d love come hear your outcomes on twitter.


There have been various other notably fast stock ATVs end the years and I’d choose to track under the height speeds of part slower however not less popular ATV brands in the close to future.

UTVs and Side by side vehicles are now common in the marketplace and due to having actually larger engines deserve to go also faster 보다 the speeds provided above, if conditions are favorable.

My opinion: top speed isn’t as vital as acceleration in an ATV due to the fact that you’re most likely to it is in riding in unstable terrain. Friend will need to throttle up and down too frequently to reach peak speed anyway. Still, it’s fun to have a baseline of your quad’s height stock speed prior to you update it with performance parts. Ns hope the figures above helped.


The height speed of an ATV is minimal by the final gear ratio and wheel size. Horsepower and weight only determine just how long it will take to reach peak speed, the final gearing ratios absolutely collection maximum possible speed on an ATV. You can only go as fast as the equipment ratio will allow. A lighter ATV and more powerful engine will certainly accelerate an ext quickly but at max RPM the gear ratio dictates top possible speed.

You have the right to increase your quad’s acceleration rate by reducing weight and increasing horsepower. If you truly want to reach a higher top speed you have to install taller and also steeper gears. Tires through a much longer radius can also aid you reach greater speeds, presume the engine is capable of increasing enough to exploit the extra size. A larger tire circumference boosts top potential speed yet it also lowers acceleration prices slightly.

I frequently see concerns asking what is the optimal speed that a 125cc engine or a 90cc engine or a 450cc engine. Engine size doesn’t dictate top possible speed, the dictates the acceleration rate in getting to the max potential height speed the your current gear ratios will allow.

To acquire a an excellent ATV height speed comparison start with a share engine and increase tire size slightly. You will probably notification that the takes a bit longer to with the same top speed girlfriend did through the smaller sized tires. After you change the gearing ratios the will come to be even much more noticeable. Her ATV will NEED much more power to with the brand-new limits but it’s no the speech that makes the greater top rate possible.

You’ll also notification that gains room not linear, they room exponential. The first increase in tires size may need a little amount that horsepower increase to preserve the very same acceleration rate. A 2nd increase in tire size, by the exact same amount, will certainly need more of boost than the first one walk to keep the very same acceleration rate. One ATV dragster has gears so steep you would certainly probably find them exceptionally unrewarding come ride v a share engine. Ns hope that helps you recognize a bit better why much more horsepower does no equal a higher maximum top speed every by itself.

Fun Fact: The peak speed on an electric battery powered ATV is not limited by the same constraints. About theory the tires can spin as quick as the amount of present the motor transforming them is able come tolerate. Through batteries large enough come sustain a high output for long sufficient an electrical ATV has actually much higher potential, and the acceleration is equally lot stronger. Speed limitations on a battery powered quad are battery size, electric motor capacity, friction, heck also wind resistance will certainly come into play at some point. Future ATV speed records belong to electric quads, as soon as battery become much more affordable and also easier come recharge.
