Dirt bikes are among the lightest types of bikes in the market. However, there can also be weight differences depending on a dirt bike’s CC or cubic capacity.

If you’re wondering how much does a 450 dirt bike weigh, it averages 260 pounds. However, there will be variations depending on the model, build, and modifications you applied to your vehicle.

In this article, we’ll look at the weight range of a 450 dirt bike and check the average weight of some well-known models.

Weight Range of 450 Dirt Bike


A 450cc dirt bike is considered the biggest type of dirt bike there is. However, it is still categorized into different groups, with each one having a different average weight.

There’s the motocross bike, which often weighs around 240 pounds on average. Meanwhile, a cross-country enduro bike will be a bit heavier at around 254 pounds.

Next is the off-road enduro bike which averages 262 pounds, and the last one will be the dual sport bike with an average heft of 290 pounds.

Factors Affecting a 450 Dirt Bike’s Weight

A dirt bike is relatively light compared to other types of motorcycles. Its average weight can be affected by the following factors:

1. Two-Stroke Vs Four-Stroke


One of the most common factors that affect the weight of a dirt bike is whether it uses a two-stroke or a four-stroke engine.

Dirt bikes that have a two-stroke setup are lighter compared to those with a four-stroke specification. Not only that, but they can also accelerate faster due to their lower weight.

The reason why dirt bikes with a two-stroke engine are less hefty is due to the absence of camshafts, chains, and valves.

2. Frame Material


Another factor that contributes to how heavy is a 450 dirt bike is the material used for its frame.

In most cases, dirt bikes tend to have aluminum for their bodies. However, there are those that use steel, which makes them a little bit heavier compared to models with aluminum frames.

3. Suspension System


A dirt bike’s suspension system can also add to its overall weight. The design gets heavier the more complex the suspension system gets.

For example, the inclusion of shocks and forks can add a lot of pounds to a dirt bike. Moreover, suspension systems that are specifically designed for off-road adventures can make a dirt bike bulkier than usual.

4. Addons

As mentioned earlier, any sort of modification you add to your dirt bike will increase its overall weight. These can come in the form of skid plates, handguards, as well as aftermarket exhaust systems.

Comparing the Weights of Popular 450 Dirt Bike Models

To better understand the differences in weight between dirt bike models, let’s look at this weight chart showing some of the most popular 450 bikes in the market:

Bike Model Weight (in lbs and in kg)
Honda CRF450R 245/111
Kawasaki KX450 233/106
Yamaha WR450F 262/119
Husqvarna FC 450 227/103
KTM 450 XC-F 228/104
Suzuki RMX450Z 272/123
Gasgas MC450F 218/99 (dry weight)

Frequently Asked Questions

Can I make my dirt bike lighter than it already is?

Yes. In fact, there are several ways to make this happen. The most common method would be to use lighter materials for its parts.

For example, if your dirt bike uses an exhaust that’s made of steel, you can replace it with a titanium exhaust instead.

You can also switch out plastic parts with lightweight “race plastics” that are sold on the market.

Does a dirt bike come with a weight limit?

You won’t necessarily find a weight limit specified on a dirt bike upon purchase.

However, the general rule of thumb is to have 1 cc for every pound of weight. Of course, a dirt bike with a 450cc engine will have a higher limit than a 50cc one.

What are some of the lightest dirt bikes on the market?

There are lots of lightweight bikes on the market with 450 dirt bike horsepower. But as far as the lightest goes, that would be the dirt bikes from KTM like the 450 SXF.

Of course, other brands have strived to manufacture low-weight vehicles as well without compromising their overall performance and durability.


As you can see, dirt bikes are fairly lightweight on average. This is partly due to the fact that they’re made of lighter materials, which allow them to maintain their speed on rough terrain.

Hopefully, this article answers the question of how much does a 450 dirt bike weigh on average. The estimate here should help you pick your next motorcycle while considering your truck’s load limit.
