A number of us filth bike riders have an intense want for velocity and we’re at all times searching for a machine that may actually rise up and transfer. Engine output is likely one of the largest figuring out elements, so if velocity is your prime precedence, you’ll wish to know the way quick 500cc filth bikes can go. 

The typical 500cc filth bike has a prime velocity of about 100 mph. Sure fashions can attain speeds as excessive as 120 mph, whereas others are restricted to the low 90s.

In most circumstances, riders gained’t be capable to safely attain the utmost velocity if they’re utilizing bikes for off-road driving. 

500cc bikes are bigger, heavier, and extra highly effective than 125cc, 150cc, 250cc, or different bikes with much less displacement. However energy and engine measurement aren’t all the pieces and a few folks might even discover that these bikes are too quick for his or her wants. Try the desk under for some comparisons between a couple of 500cc fashions. 

Make and Mannequin High Velocity Acceleration (0-60 mph) Engine Measurement Horsepower Torque
Kawasaki KX500 120 mph Unknown 499cc 63.5 hp 48.4 lb-ft
SWM RS500 109 mph Unknown 501cc 26.8 hp 18.44 lb-ft
Husqvarna FE 501S 101 mph 4.4 seconds 510.9cc 44.5 hp 31.6 lb-ft
Honda CR500R 92 mph 3.8 seconds 491cc 67.5 hp 55.7 lb-ft
KTM 500 EXC-F 90 mph 3.9 seconds 510.9cc 58 hp 27.7 lb-ft
Beta 500 RR-S 90 mph Unknown 477.5cc 47 hp 32.6 lb-ft

500cc bikes are much less frequent than many different sorts, so it’s good to be taught a bit extra about them earlier than making a dedication. Under, we’ll cowl how these filth bikes evaluate to different fashions with much less displacement, by way of velocity.

How the Velocity of 500cc Grime Bikes Evaluate

You most likely have discovered that 500cc filth bikes are quick, However with no level of comparability, it’s laborious to place this all into context. Clearly, there’s a variety of specs and measurements to have a look at when evaluating filth bikes, so we’re simply going to have a look at total averages. 

Engine Measurement Common High Velocity Horsepower
125cc 45 mph 8 hp
150cc 50 mph 12 hp
250cc 70 mph 30 hp
450cc 90 mph 55 hp
500cc 100 mph 51 hp

As you possibly can see, there’s a reasonably linear development from one engine measurement to the following. Because the engine measurement will increase, so does the highest velocity and horsepower. Curiously, you’ll discover that 450cc bikes have barely increased horsepower than 500cc fashions do. 

There are some 500cc fashions which have horsepower measurements which are increased than 55, however typically talking, the following smallest engine measurement has the next horsepower ranking. As talked about above, horsepower isn’t the one figuring out issue although. Total, 500cc filth bikes are nonetheless sooner than the smaller fashions on account of engine torque and different elements.

If you need a motorcycle that balances velocity and agility although, you might wish to discover a smaller mannequin. 250cc bikes are very fashionable these days they usually nonetheless have an honest quantity of horsepower. They will additionally attain common prime speeds of about 70 mph, which is often greater than sufficient for many riders. 

Two Quickest Inventory 500cc Grime Bike Fashions

For those who actually simply need the quickest 500cc filth bike you will get your arms on, there are a couple of nice choices on the market. We’ve explored a few of these above, however let’s dive into deeper element on a few the quickest bikes ever made. 

#1 – Kawasaki KX500

To begin with, there’s the Kawasaki KX500. went so far as to name this bike “The one bike to trip earlier than you die”. That’s excessive reward and it speaks to the facility and high quality of this machine. 

With a prime velocity of 120 mph and 48.4 pound-feet of torque, this bike was insanely quick and highly effective. To a point, this energy was its personal undoing although! Most individuals simply couldn’t deal with a Kawasaki KX500 as a result of it was too troublesome to manage. For individuals who wished to push their limits although, this was an incredible and formidable bike.

#2 – Husqvarna FE 501S

The Husqvarna FE 501S is one other high-speed bike that’s value a glance. This one ranks a little bit bit above the typical with a prime velocity of 101.5 mph. It is a dual-sport bike that’s nonetheless in manufacturing right this moment! The 2022 mannequin has one of many largest and strongest engines that Husqvarna has ever created.

Though its acceleration is a tiny bit slower than a few of its rivals, this bike will often take the win relating to prime velocity! It has an excellent suspension that retains the rider steady and comfy. This high quality makes it good for a path bike.

If desired, the Husqvarna FE510S can be used as a street-legal bike. This makes it handy for individuals who wish to use them for transportation as a substitute of simply recreation. As a dual-sport bike, you get the perfect of each worlds.

Engine Measurement

For those who’re new to the filth bike world, you’ll have seen this time period earlier than however don’t know what “cc” truly refers to. This metric is used to explain an engine’s measurement. Primarily, it’s what number of cubic centimeters (cc’s) the engine’s piston displaces because it rotates. The larger the piston or longer the stroke, the extra CC’s of quantity the engine displaces.

So an engine that’s 125cc is way smaller than an engine that’s 500cc. The larger the quantity, the larger (and usually the extra highly effective) the engine is.

So far as engine sizes go, 500cc is fairly huge. Most filth bike engines are nearer to the vary of 250cc-450cc and never lots of them transcend these limits these days. Bikes which are designed for youngsters or inexperienced riders will probably be on the decrease finish of the spectrum and can often be between 50cc-125cc.

Most bikes gained’t have precisely the identical cc measurement that seems on their label. For those who take a look at the listing of instance bikes above, you’ll discover that the majority of their engine sizes are between 470-510cc’s. The “cc” classifications are principally used as a strategy to separate the bikes into completely different measurement courses. It’s not a inflexible separation technique, so that you’ll often discover teams which are separated by variations of 50-100cc’s. 

Not many common filth bikes can attain speeds of 100 mph, however that is par for the course for many 500cc bikes. Nevertheless, it’s not a 1-1 comparability. Take a look at the KTM 500 EXC-F for instance. It has a 510cc engine, however its prime velocity is just 90 mph. That is slower than some bikes with smaller engines. Typically talking although, relating to velocity, bigger engines often imply sooner bikes. 

Due to the extra weight that comes together with it although, these bikes are typically much less agile on the course. If a motorcycle is just too quick to deal with or management, it’s not often a best choice for aggressive filth biking. 250cc fashions overtook 500cc fashions in efficiency a number of years in the past and these have develop into extra commonplace in competitions.

For this reason 500cc bikes are much less frequent now. Many individuals are searching for one thing lighter and extra maneuverable, even when they lose a little bit of velocity within the course of. These bikes are nonetheless nice choices for path driving or avenue bikes although as a result of they’ll simply sustain with freeway speeds. 

High Velocity 

One of many largest appeals of 500cc filth bikes is their spectacular prime speeds. For those who seek the advice of the chart above, you’ll discover that the entire examples can hit no less than 90 mph. Normal highways velocity limits are often between 65-80 mph, so even the slowest 500cc bike can simply sustain with site visitors. 

Because of this, 500cc bikes are perfect for people who find themselves searching for a pleasant dual-sport bike or avenue bike. Many riders will take a 500cc filth bike and cheaply convert it to a street-legal filth bike.

These fashions aren’t at all times the perfect for off-roading although as a result of hitting a pothole or tree department at these speeds could possibly be lethal. If riders use them for path driving, they most likely gained’t be capable to hit most velocity, however the choice remains to be obtainable to them. 

On the higher finish of the spectrum, there are a couple of 500cc bikes that may journey as much as 120 mph! The Kawasaki KX500 is an efficient instance of a motorcycle that may attain these speeds. It’s troublesome to think about going that quick in a automotive, not to mention on a dust bike. 

500cc bikes are sooner than nearly all of filth bike fashions, however there are nonetheless bikes that may go even sooner, imagine it or not. There are a couple of bikes available on the market which are outfitted with 600 or 700cc engines and these will be capable to hit even increased prime speeds.

Once more, there are fewer of those available on the market as a result of many of the filth bike neighborhood is searching for energy and agility above all else. Velocity is actually good, however sure, there could be an excessive amount of of a great factor.


In the case of acceleration, filth bikes are often fairly related no matter their engine measurement. That’s a part of the enchantment of those autos in any case! They’re punchy, highly effective, and may rise up to hurry shortly. 

By averaging the measurements from our instance bikes, most 500cc filth bikes can speed up from 0-60 mph in about 6.5 seconds. A number of fashions can speed up even sooner although! For instance, the Honda CR500R can go from 0-60 in 3.8 seconds. That’s numerous velocity, so that you’d higher maintain on tight!

Though these acceleration speeds are appreciable, they don’t change a lot as engine measurement will increase or decreases. Many riders who’ve bikes within the 125cc to 250cc vary have reported related acceleration instances (supply). It’s because these bikes have lighter frames and completely different gearing ratios that may make up for the dearth of energy. 

Horse Energy 

Horsepower (additionally known as hp or energy) merely refers back to the quantity of energy that an engine can produce. This measurement is calculated by measuring how a lot energy it takes to maneuver 550 kilos one foot in a single second (supply). This measured charge is then referred to as the horsepower of the particular engine. 

Mainly, horsepower is a time period that refers back to the quantity of pressure that’s required for motion in addition to the speed of time that it takes to attain the purpose. It’s a multi-faceted measurement, however it’s necessary to remember whenever you’re evaluating the specs of various filth bikes. 

Bikes with excessive horsepower measurements are likely to speed up sooner, however they could not really feel very highly effective relying on how a lot torque they’ve. Horsepower tends to have peak ranges of efficiency as effectively at sure engine speeds or RPMs (engine revolutions per minute).

Because the bike hurries up, the nearer you get to the utmost horsepower. Most 500cc bikes will hit their most horsepower someplace between 6,000-8,000 RPM. As soon as the bike passes a sure RPM or goes over it, some horsepower will probably be misplaced. Inertia and gravity do a part of the job as a result of a motorcycle can proceed to hurry up even as soon as the height engine efficiency has been reached.

So a dust bike’s horsepower may help you speed up and attain excessive speeds, however upon getting reached them, its total efficiency might dip.

There’s a fairly first rate vary of horsepower for 500cc filth bikes. Within the examples above, the bottom measurement is 33.5 hp whereas the best is 63.5 hp. Once more, it isn’t an ideal 1-1 comparability, however bikes with the upper horsepower measurements tended to have increased prime speeds as effectively. 

Take a look at the Kawasaki KX500 for instance. This bike has 63.5 horsepower and its prime velocity is 120 mph (one of many highest on the listing). It’s thought-about to be a beast and is likely one of the quickest and strongest 500cc bikes on this planet. So although horsepower will not be the one figuring out issue relating to velocity, a motorcycle with very excessive horsepower ranking is prone to be fairly quick. 


Torque and horsepower are sometimes confused, however these two play completely different roles relating to filth bike velocity. Torque is a rotational pressure that’s typically measured in pound-feet. It merely refers to pressure and doesn’t consider time as a part of the equation. 

In sensible phrases, this measurement refers to how simply the bike can overcome obstacles and deal with steep inclines. In case your bike has excessive torque meaning it’s able to producing numerous rotational pressure, even when it doesn’t transfer very quick. 

Image your self driving a bicycle for instance. While you’re struggling to go up steep hills, you progress extra slowly, however you place extra energy into every rotation of the wheel. That’s torque in motion! Besides whenever you’re on a dust bike, the engine is what offers the torque, not your leg muscular tissues. 

Torque and horsepower are each methods to measure a motorcycle’s energy, however they function in several methods. Horsepower is highest and strongest when a motorcycle is touring at a excessive RPM. Alternatively, torque is the strongest and best to really feel when a motorcycle is working at a low RPM.

Grime bikes with excessive torque capabilities will probably be higher outfitted to deal with off-road situations and inclines, however they gained’t essentially be sooner or slower consequently. 

For example, the Honda CR500R has a torque of 55.7 pound-feet. While you evaluate it to a motorcycle just like the Kawasaki KX500 which has a torque of 48.4, you’ll word that they’re fairly shut of their torque capabilities. Nevertheless, the Kawasaki has a prime velocity of 120 mph whereas the Honda can solely attain 92 mph. 

Although each of their torque measurements are pretty excessive, their most speeds have a large hole. Torque is nice for a mud bike, however it doesn’t play an enormous function relating to growing the highest velocity. 


For those who have been unfamiliar with 500cc filth bikes, hopefully, you perceive their capabilities a bit higher now! These are pretty massive and highly effective bikes that may often attain prime speeds of 100 mph or increased.

This degree of velocity isn’t for everybody although, and 500cc bikes are much less frequent to see within the filth biking world these days. A better name for agility reasonably than velocity has led to this decline. Nevertheless, some manufacturers are nonetheless releasing fashions to today and there are each previous and new 500cc bikes obtainable for individuals who have an interest. 

If velocity is your primary purpose, then a 500cc bike is perhaps the proper match for you! Open up the throttle on the take a look at monitor or take a street-legal mannequin out for a spin on the highway and also you’ll don’t have any hassle maintaining with site visitors.
