Anyone new to ATVs will, at some point, wonder how fast they have the right to actually go. It’s not likely that you will certainly be speak at this speeds very often, yet it’s simply one that these points we simply want to understand out that pure curiosity.

You are watching: How fast does a 125cc atv go

Or, possibly you are in the procedure of to buy a brand-new four-wheeler and just desire to make sure you won’t acquire disappointed by the performance of the bike size you space getting?

For most ATV models, girlfriend won’t acquire these numbers from the manufacturers themselves. So i did a tiny digging to discover as great of approximates as possible.

Today’s most powerful sports and utility ATVs have the right to reach top speeds of 80mph (128km/h). Moderate size bikes averages at around 65 mph (104km/h). Youth ATVs have actually speed limiters so the the parent have the right to decide precisely how fast it have the right to go.

Comparing stock height speeds of different ATV engine sizes

These space the height speeds of the fastest share ATVs I can find within each cc engine size. My research study included all of the major brands.

Why won’t manufacturers state your machine’s peak speed?

For all handy purposes, as long as the bike walk 50 MPH safely, friend really perform not need it to go any type of faster.

But if you decide to press it even further anyways, you will uncover that it’s no comfortable, practical, or very safe. It also makes a severe affect on the fuel economy.

When friend research different ATV models, you will an alert that many manufacturers won’t state their machines top rate in your spec sheets (except through speed minimal youth models to display how slow they deserve to go).

And lock have good reasons because that not concentrating on blazing height speeds.

ATVs space not designed an extremely well come be provided at high speeds. They are meant to be an effective at lower speeds and need large engines because that this reason. However they room not meant to collection any rate records.

The suspension is too soft, the tires room too aggressive, and the CVT transmission non-ideal for higher speeds. The fairly short wheelbase and also spacing compared to a vehicle do additionally negatively influence high-speed performance.

So the manufacturers perform not desire riders come be advertise to with potential peak speed on your machines, together it’s not what they space really designed for and also could end in disaster.

Most manufacturers clearly give disclaimers similar to the one you find on Can-Am spec sheets: “Avoid extreme speed. ” They do so because that a reason.

If you’re searching for speed, a motorcycle or a fast automobile is a much far better option.

But what about quad racing?

Racing quads space equipped v upgraded suspension, have a wide tire width, and are ridden by knowledgeable riders. This cannot be contrasted to your median stock utility or recreation bike.

Some sporting activities models have better suspension indigenous the factory, but it is still not a maker meant because that chasing high speeds.

Speed limiters and actual optimal speed

You will find different varieties of speed limiters installed on plenty of of the ATVs on the sector for assorted reasons. You’ll even uncover this ~ above “unrestricted” optimal performance bikes favor the Polaris Scrambler.

But the real function of why castle are set up varies somewhat depending upon what form of bike you room getting.

You’ll often uncover that it’s not actually the engine dimension (displacement) that’s the limiting factor of how fast the quad goes. Over there is commonly plenty of power easily accessible for even greater speeds.

But the speed needs to be limited at some suggest to protect those of us that don’t understand the extreme dangers associated with doing these speeds themselves. Therefore they download limiters.

The same is true in many cars, motorcycles, and also any various other high performing machine. Usually, castle are collection to a speed so high that it is no something one would certainly ever notice for the median user. Friend will never ever be walk this fast anyways.

But it help to describe why there are noticeable sport in top speed top top quads with identical engine size but from different manufacturers in part cases.

You will even find bikes with smaller sized engines the outrun the enlarge ones. Often this is likely as result of a limiter set at various maximum speeds.

I strongly advise versus messing with the height speed limiter on these bikes. The is there because that a an excellent reason!

A limiter have the right to be either mechanical or digital or both

A mechanic speed limiter uses a mechanical barrier to avoid you from applying full throttle.

This can be in the form of an adjustable screw top top the handlebar, plastic components inside the carburetor, or shims limiting air flow in various areas inside the engine. Other species exist as well.

Electronic limiters are common on bikes with digital fuel injection. The fuel injection system gets notified to cut back on fuel as shortly as the ATV will the set limit.

Speed limiters are set up on children’s and also youth ATVs together a critical safety feature to protect beginners and inexperienced riders.

Some bikes come with flexible limiters so that the parent can increase speed gradually as the riders riding an abilities and experience increase.

Most the the smaller sized sized ATVs are qualified of speed in the range of 30 mph with some light tuning, removing rate limiters, etc.

I’m not telling you this since I advise you to perform so yet so the you’ll recognize why there room such far-ranging variations in the top speed that the presumably identically sized smaller bikes. That is, in most cases, no due to huge variations in yes, really engine performance.

For larger beginners, Can-Am includes a learning key that holds a password that electronically limits the bike’s speed. This is a good safety attribute I hope an ext manufacturers will sell in future models.

ATV top speed v tracks

When you install monitor on the quad, you provide up a the majority of the speed at the same time. As a general preeminence of thumb, you may expect the optimal speed to drop by about 50% as result of the sprockets’ various output ratio.

*
Installing tracks will impact your optimal speed.

Because the this, the internals of her bike demands to move twice as fast to preserve the same speed once running in the same gear and with the exact same RPMs.

It’s wise to save this in mind once you’re chasing peak speed through your new tracks. It placed a many strain on your gearbox, diffs, and CV-joints.

How to rise top speed

If you, in spite of the warnings, still wish to increase your bike’s height speed, there are several ways you can go about it. Disclaimer! All modifications are excellent at your own risk! I execute not recommend any type of of them.

Change tires dimensions

Bigger tires have a bigger circumstance, which way the tire travels farther pr. Revolution. This will successfully increase the peak speed of your bike.

Remember that you also need to download a clutch kit if you increase tire diameter by more than a couple of inches. If you don’t, friend will lose a many power and also may confront belt slipping issues and also burning belts.

Change gearbox gearing ratio

If her bike has a gearbox v sprockets and chains, girlfriend can readjust one that the sprockets to increase your height speed. However, this is actually most generally done to alleviate top speed and simultaneously enhance acceleration by installing a smaller sprocket.

Install a racing clutch

By installing a gyeongju clutch, girlfriend can select one that uses different dimensions that clutch sheaves, transforming the bike’s top speed follow to your needs.

Improve engine strength output

I won’t go into the details on how to rise the power output of her bike’s engine, as this topic deserves a article of that own. However doing for this reason will likewise give girlfriend an advancement of height speed.

Remove speed limiter

This one is rather obvious, but removing it will improve your top speed if your bike has any kind of speed limiter installed. Be mindful you might be voiding your warranty and also breaking a couple of laws if you decision to walk this route.

Mechanical speed limiters are the easiest to eliminate as lock usually need you to slightly disassemble and remove the part that is limiting your throttle.

However, if your bike has actually an digital speed limiter, you might need reprogramming that the bike to disable the limiter. Part dealers perform this because that you; rather don’t.

For mine Polaris Sportsman XP 1000, over there wasn’t any kind of software available to eliminate its peak speed limiter the 60km/h (37,3 mph). This certain bike is sold as a tractor forced by regulation (Norway) not to go any type of faster than this.

Change the gearing ratio

If your bike has an open sprocket and chain, transforming top speed is easy. Boosting the dimension of the former sprocket (clutch) and reducing the dimension of the rear sprocket (axle) will both give you a greater top speed.

People right into quad gyeongju tweak gearing proportion to discover the optimal setup for each monitor they space racing.

Tracks with long stretches require greater top speeds, while monitor with countless turns advantage from a much better acceleration at the cost of greater top speeds.

Reflash the ECU

As i mentioned, many bikes will actually have actually an electronic speed limiter to stop riders indigenous attempting speed much higher than the machine is really designed for.

The limiter top top Polaris Scrambler XP 1000 kicks in at about 80mph, but there have been reports of civilization reaching speeds in the selection of 100mph just by flashing brand-new software to their bikes ECU.

The Scrambler XP 850 even has a greater stock top speed, with the limiter reportedly collection at 83 mph.

Again, ns strongly advise versus doing this modifications. And also quite frankly, ns don’t really check out the allude of it uneven you are into some serious racing. And don’t gain me wrong, i love speed. Simply not these kinds of speeds on one ATV.
