Are you out there for a quick bike, however don’t actually know the place to begin? We’re going to go excessive speeds for 21 completely different fashions of grime bikes, so that you’re in the proper place!

The typical high velocity of the below-mentioned grownup grime bikes is 92.3 miles per hour. The typical high velocity of the below-mentioned kids’s bikes is 37.3 miles per hour. High velocity will fluctuate based mostly on terrain and the burden of the rider.

With so many fashions of grime bikes, the common velocity will actually rely on the particular mannequin of motorbike you’ve obtained, together with a few different components. Let’s discuss and evaluate a few of the completely different fashions!

Grownup Bikes

These examples had been chosen as a result of they’re considered being within the quickest vary of bikes. These bikes are large, loud, and might get going fairly quick on an open course.

Honda CRF 450 4 87
Yamaha WR 250 4 88.8
Suzuki DR-Z 400 4 114
Honda XR 650 4 110
Kawasaki KLR 650 4 98
Husqvarna FE 510 4 101.5
MuZ Baghira 660 4 102
Kawasaki KX 250 2 76
KTM SX 250 2 71
Suzuki RM 250 2 78
Kawasaki KX 450 4 89

Let’s discuss briefly concerning the grime bike mannequin, engine dimension, engine stroke, and naturally, high velocity. If the principle curiosity if simply high velocity, why embody all the opposite additional data? Whereas realizing the grime bike mannequin and high velocity will provide help to discover the bike itself, realizing how large the engine is and what KIND of engine the bike has offers you a a lot clearer thought of the capabilities of the bike, particularly the place velocity is worried.

For instance, extra highly effective engines typically aren’t made in a two-stroke possibility. Along with realizing the cc of the bike, you’re desirous about, realizing the stroke may give you a good suggestion of the kind of velocity you’re going to have the ability to coax out of your bike. Two strokes are extra sometimes extra fast at choosing up preliminary velocity, whereas four-strokes sometimes have the next basic high velocity, whereas not being fast as fast to hit their high velocity, typically talking.

Should you’re trying to purchase a motorcycle since you need one thing with a high-speed threshold, likelihood is you’ll in all probability be utilizing your bike on the street, or for racing, since excessive speeds aren’t typically tremendous helpful or vital for path using.

Grownup Filth Bike Dimension Breakdown

There are many grownup grime bikes on the market, however I’ve narrowed them down into a couple of completely different classes. Under are the sizes for every grime bike class and their respective speeds and dimension.

250cc Filth Bikes

Common Velocity

Within the chart of surveyed grime bikes, the common high velocity for 250cc grime bikes is 78.45 miles per hour. The largest hole in velocity between the 250cc grime bikes on the desk is 17.8 miles per hour, with the bottom velocity being 71 miles an hour from the KTM SX, and the very best velocity being 88.8 miles an hour, introduced by the Yamaha WR. In the event that they’re each 250cc grime bikes, why is there such a big discrepancy in velocity?


Put merely, the KTM SX has a two-stroke engine, and the Yamaha WR has a four-stroke engine. Since two-stroke engines are lighter and constructed to finish their engine cycle in simply two “strokes” of the engine, they often do have a faster “rise up and go” than the four-stroke engine does. Nevertheless, regardless that four-stroke engines are heavier, and constructed to finish an engine cycle in 4 strokes versus the 2, they do have a capability for greater “high velocity”.

This may make the KTM SX, or different two-stroke engine 250cc grime bikes extra ultimate for path using, and areas the place you’ll be needing extra boosts of preliminary velocity, and never worrying a lot about sustaining a excessive high velocity.

The Yamaha WR, alternatively, together with different comparable four-stroke 250cc grime bikes, will likely be higher if you happen to’re not as frightened about bursty velocity, and extra targeted on hitting and sustaining a excessive velocity for a extra prolonged time frame. The Yamaha WR is right for racing on extra open type tracks, using on the street (so long as you’re road authorized!), and is a superb bike to decide on nice if you happen to’re needing an possibility that may help a bigger rider.

400cc-450cc Filth Bikes

Common Velocity

Within the chart of surveyed grime bikes, the common high velocity for 400cc-450cc grime bikes is 96.67 miles per hour. The most important hole in velocity exists between the Honda CRF and the Suzuki DR-Z, at 17 miles an hour. The highest reported velocity of a Honda CRF is 87 miles an hour, whereas the highest reported velocity of the Suzuki DR-Z is 114 miles per hour.


Every of the 400cc – 450cc bikes within the chart have 4 stroke engine. Why aren’t there any 250cc engine grime bikes included within the comparability? When you begin moving into the upper “ccs”, or bigger engine sizes, bikes start to be made extra typically in 4 stroke engines. As soon as two stroke engines get to a sure dimension, they attain some extent the place they turn into extra harmful and unstable, at which level the dirk bike turns into accessible virtually completely with 4 stroke engines, that are in a position to deal with the pressure and work which comes from having a extra highly effective engine.

510-660cc Filth Bikes

Common Velocity

Within the chart of surveyed grime bikes, the common high velocity for 510cc-660cc grime bikes is 102.88 miles per hour. With a high velocity hole of 12 miles an hour within the noticed bikes, the Kawasaki KLR offers us our lowest high reported velocity at 98 miles an hour, with the very best reported high velocity being 110 miles per hour from the Honda XR.


Every of those bikes come completely with a 4 stroke engine. With engine sizes starting from 510ccs to 660 ccs, these are some extraordinarily highly effective engines, which aren’t feasable to make in a two stroke mannequin.

There’s much more that goes into a extremely spectacular motorbike than simply high velocity, like horsepower and torque! See which inventory bikes are probably the most highly effective right here!

Child’s Bikes

If grime biking is one thing you’re wanting your youngsters to get into, or one thing they need to get into themselves, velocity might be one thing you’ll be fascinated by as a involved mum or dad.

As a basic rule of thumb, bikes that run on electrical motors are going to be slower than combustion engines, so concentrate on the variations in velocity and upkeep that include the various kinds of bikes, in addition to any variations of inherent dangers that include having a toddler on a mud bike.

Yamaha TTR 50 4 30
Honda CRF125F 125 4 45
KTM 50 SX 50 2 45
KTM 65 SX 65 2 62
Coolster QG50 49cc 50 2 30
DR-X Holeshot 50cc 50 2 25
Apollo DB25 70 4 37
RPS Xmotos 70 4 50
Kuberg 2016 Freerider 48 Volt
N/A 34
Razor SX500 McGrath 36 Volt
N/A 15

On the subject of kids’s bikes, the slowest bike is a Razor SX500 McGrath. Made with an electrical motor, it hits a high velocity of 15 miles an hour. The quickest kids’s bike on the chart is a KTM 65 SX. With a 2 stroke 65cc engine, this bike offers us all the way in which as much as 62 miles an hour, which ought to in all probability be reserved for the youngsters who’ve expertise with grime bikes, and know what they’re doing.

This offers us a distinction of 47 miles an hour between the quickest and the slowest of the youngsters’s bikes talked about above, which offers you a lot of leeway to find a motorcycle with a high velocity that’s simply best for you and your loved ones.

Children Bike Breakdown

The time period “Children bikes” matches a extremely extensive spectrum of bikes. There may be a lot room for selection when deciding on a youngsters bike, however by way of high velocity, there’s loads of selection.

Under are a number of sizes and lessons of grime bikes that might be thought-about the proper dimension for kids. Their speeds are a lot decrease than the adults clearly, however they’re nonetheless fairly quick.

Electrical Filth Bikes

Electrical grime bikes are a little bit of a joke when put subsequent to the actual factor. They will transfer, however you aren’t going to get going very quick.

After I was youthful, I truly obtained certainly one of these bikes as a present. I attribute a number of my preliminary intrigue with grime biking to that little razor. It was simply sufficient for me to get a style, however not sufficient for me to have any actual enjoyable. Mainly it was like having a motorcycle that you just didn’t must pedal in flat areas however nonetheless wanted assist getting up steep hills. Truthfully I feel it’s a higher thought to only get an precise grime bike, however these are typically fairly low-cost so if you find yourself regretting the acquisition you aren’t out an excessive amount of.

These bikes hardly ever recover from 35 miles per hour, and even that’s fairly the stretch. They solely final for about an hour earlier than they must be recharged, which means they’ve a spread of 5-10 miles.

They’re enjoyable for using across the culdesac, however they’re horrible for off-road. I’ve seen little youngsters attempt to use their electrical grime bikes on all types of little grime hills and tracks, however I’ve by no means seen any certainly one of them efficiently do something on them. They at all times attempt to get their little bike to take them up the smallest of hills, solely to be dissatisfied that they’ll’t rise up to the highest with out getting off of their bike and pushing. These bikes appear nice on paper, however in actuality, they only don’t have the ability to get going quick sufficient to do something actually enjoyable.

50-70cc Filth Bikes

These bikes are actually small. That is what you get your 5-year-old child that desires to have an actual grime bike over an electrical one, this can be a nice possibility. You should definitely get them an awesome helmet although, as a result of a bit child on a mud bike this dimension can actually get going.

You may count on these grime bikes to rise up to round 40 miles per hour, which is nice contemplating how little they’re.

In case your youngster is new to grime bikes, and I’d assume they’re, I counsel getting a mud bike that has gears, after which simply don’t train them easy methods to change gears till they’re prepared.

70-140cc Filth Bikes

This dimension of grime bike is the place you might be beginning to get into {the teenager} vary and even some very small adults. This dimension of grime bike is designed to get going at a lot quicker speeds, and you’ll count on them to hit anyplace between 40 and 60 miles per hour as a high velocity.

These bikes are a transition bike, and I’d advocate erring on the aspect of bigger. Youngsters get larger quick, and they’re going to outgrow their grime bike in a 12 months if you’re not cautious.

In case your youngster began out on a 50cc and is prepared for a giant improve, get them a 110 or 125cc as a substitute of creating the small bounce to a 70. They’ll get pleasure from themselves far more, and so they have the chance to develop into their bike. It might be a bit too quick for them at first, however they are going to be superb and might regulate to the added velocity.

These bikes are nice for starting youngsters as properly, but when your teen has an honest quantity of expertise on an everyday bike, then they may be happier on one thing a bit larger as properly.

150-250cc Filth Bikes

Though I didn’t checklist any examples of those grime bikes, I feel they’re price mentioning. That is the scale of a mud bike that you just get if you’re a newbie. They’ll get going round 70-80 miles per hour as a high velocity, however since they’re a newbie grownup bike I didn’t assume they need to be in both class.

Nice for newbies, however if you’re trying to be the quickest man on the market then you definitely want one thing a bit larger.

What’s the Massive Deal With Velocity?

High velocity is enjoyable to know and may give you a good suggestion of your bike’s capabilities, however there are solely a pair eventualities or locations the place you’ll truly strategy or hit your bike’s high velocity.

Races, open desert, and roads (in case your bike is road authorized), are the one locations the place you’d fairly come near hitting your high velocity.

Filth bikes are designed to speed up quick, and never have a extremely excessive maintained high velocity. Those that grime bike usually are on trails or a observe that has a number of twists, turns, hills, and different obstacles. These obstacles require a number of slowing down in addition to rushing again up. Filth bikes deal with this by having nice acceleration at the price of not having a excessive maintainable high velocity. The gear system is designed for a really quick restoration from a short decelerate as a substitute of utilizing the engines full energy to get the bike at actually excessive high speeds.

There’s a enormous distinction between grime bikes and road bikes, and this web site is certainly an advocate for grime bikes. I’ll say nonetheless that if you’re trying to get going actually quick, then a road bike may be a significantly better possibility for you. Their transmissions are typically constructed for greater speeds as a substitute of acceleration within the brief time period. If all you might be in search of is wind in your face, grime bikes will not be the one reply to your downside.

Let’s go over some methods you may minimize down on the burden of your bike that doesn’t have the potential to compromise its structural integrity. Race day child, let’s go!

What To Think about

When making an attempt to resolve which bike or bikes you must experience, or when choosing a motorcycle for another person, you’re going to wish to bear in mind the expertise of the rider. With the variations in high velocity, engine cc, and torque, the ability and method the rider possesses needs to be considered.

High velocity just isn’t one of the best indicator for grime bikes. There are such a lot of different components that must be thought-about a couple of grime bike than simply that.


Whereas your bike could have a base high velocity, there are a number of methods you may improve the velocity of your bike, to an extent. The obvious of those methods is to both cut back the burden of your bike, or discover a option to cut back your individual weight.

Methods to scale back the burden:

  • Hit the lavatory? – Yeah, this doesn’t actually have something to do with the burden of your bike, however it does have loads to do with the burden on your bike. Should you’re changing nuts and bolts in your bike to save lots of minuscule ounces, taking a visit to the lavatory earlier than you race will make a a lot larger distinction than changing these screws will. You may solely take a lot weight off your bike with out compromising structural stability, so be sure you do your half!
  • Nuts and Bolts – As I discussed beforehand, you may substitute nuts, bolts, screws, and the like, with titanium. The draw back, as is so frequent with any type of improve, is the value. Coming at (hopefully) no shock to anybody, titanium components are a tad bit spendy, so that you’re going to must weight the price of…properly… price to profit and resolve if that’s an improve you’re prepared to make.
  • Gasoline tank! – Should you’re racing, examine to see if you happen to really want a full tank of gasoline to complete the race. Are you truly going to expire earlier than the end line if you happen to don’t high off? Determine how lengthy the race is, work out what sort of mileage you get on the observe, and fill your bike up accordingly. Leaving out anyplace from a half gallon to a gallon of gasoline will take off a number of weight out of your grime bike, so if you happen to don’t want that full tank, don’t deliver it to the observe.
  • Half Replacements – The obvious and possibly frequent substitute or alteration individuals make to their grime bikes to make them lighter is to exchange the exhaust. Typically made out of aluminum or stainless-steel, they add fairly a little bit of weight to your bike that may be lessened by changing it with, yep, you guessed it, titanium.
    You may be considering to your self “isn’t titanium heavier than aluminum”? Sure, it’s. In case you have two exhausts constructed to the very same measurements, one out of titanium, and one out of aluminum, the aluminum one will likely be lighter.
    Titanium exhausts are lighter as a result of they aren’t constructed precisely like aluminum exhausts. Titanium is stronger, which suggests titanium exhausts might be constructed to completely different, lighter and thinner specs.
  • Plastics – There’s a great probability that your bike both has the plastics that it got here with nonetheless on it, otherwise you have changed them however for aesthetic functions. There are particular racing plastics which you can purchase which can be lighter, minimalist in order to not add additional weight you don’t want, but additionally aerodynamically formed. Not solely do they give the impression of being unbelievable and weigh much less, however they assist the form of your bike to scale back the air resistance that happens once you hit excessive speeds. Are they type of spendy? Yep. Sadly, there actually is a “value” hooked up to success.


Gearing is a change that may be made to your bike that doesn’t actually change the burden of the bike, however reasonably the acceleration and high velocity of the bike. That is achieved by serving to your bike maximize grip, and altering tire rotation ratios to realize one of the best velocity.

That is completely going to make a distinction in how your bike shifts, so ensure that and watch out. Do your analysis, or have somebody provide help to who has earlier expertise altering out the gears on a mud bike. You don’t need to do one thing mistaken and burn out your engine, break a sequence, or strip certainly one of your components.

Should you’re altering out your gears, you’re going to be altering what’s known as your “gearing ratio”. For instance, in case your rear sprocket has 300 “enamel”, and your entrance sprocket has 10 enamel, you’re going to have a gearing ratio of three. Three rotations within the entrance for each singular rotation within the again.
