The above table gives you the weight of some popular 250 cc dirt bikes that you can compare to find your preference. Bikes of some manufacturers are lighter than others. All 250 cc dirt bikes in the list have their curb weight listed.
If you don’t know what curb weight is, then keep reading to find out.
A bike needs multiple fluids to run, which are typically not included when you buy it. And the curb weight refers to the bike’s weight with all the fluid in it. So, the curb weight is calculated when the bike has a full gas tank, water, coolant, oil, and anything else required for it to run. The fluid requirement may vary depending on the engine of the bike and its model and make.
Typically, most manufacturers list the dry weight of the dirt bike, but many brands are realizing that the dry weight doesn’t really offer useful information for the riders because they won’t be riding the bike dry.
Because of this, many manufacturers are listing the wet or curb weight of dirt bikes.
Dry weight, on the other hand, offers much more useful insight for the racer community. A bike’s dry weight means it’s the weight of only the bike, and this weight does not include any oil, gas, or any other fluids that are required for the bike to run.
Manufacturers typically list the dry weight of a new bike on their website. However, some brands have begun to list the curb or wet weight. And since the amount of fuel varies in the fuel tank, most of them list the wet weight without the fuel weight.
Weight of different dirt bikes
All types of dirt bikes weigh less than other types of bikes or motorcycles, but, since there are differences in dirt bikes, there are differences in their weight.
Trail (Cross Country) vs Motocross (Race) Bikes
A trail bike and a race or motocross bike of the same brand will seem identical to the inexperienced eye. This is because both of their parts are mostly the same but they are designed with different riding styles in mind.
The design of the trail bike offers more comfort on longer rides on forest single tracks or mountains. That’s why they are equipped with a softer suspension. Also, possibly with a wide-ratio gearbox.
On the other hand, speed is demanded from the motocross bike on the race track. It also needs to be able to quickly accelerate out of turns and endure massive jumps and not bottom out. Motocross bikes also come with lower gearing with a closer ratio.
As you can understand, demands are different for a trail bike and a motocross bike. And compared to trail bikes, motocross bikes are likely to be lighter. The trail bike tends to be heavier due to the addition of a headlight, and a kickstand and might be an electric starter.
2-stroke engine vs 4-stroke engine
Generally, a dirt bike with a 2-stroke engine weighs slightly less compared to a 4-stroke dirt bike of the same size. This is because a 2-stroke engine has fewer moving parts that can add weight. A 2-stroke engine doesn’t have any rockers, valves, cam chains, and camshafts.
There are no dissimilarities between a 2-stroke dirt bike and a 4-stroke dirt bike besides the engine. To help you better understand the difference in the weight; the Yamaha YZ 250 comes with a 2-stroke engine and weighs 103 kg or 227 lbs and the Yamaha YZ 250 F is equipped with a 4-stroke engine and weighs 106 kg or 234 lbs. See the difference? Both of them are 250cc motocross bikes, yet they differ in weight because of the engine.

Why the weight is so important on a dirt bike?
The performance of a dirt bike is greatly impacted by its weight. If you pick a dirt bike that’s weight is not suitable for your weight, you won’t be able to enjoy the full experience. Also, the performance of the bike won’t be optimal for you.
A dirt bike that doesn’t match your weight class is likely to move slowly. This is because the bike won’t have adequate power according to the rider.
A 250cc dirt bike is an ideal choice for someone whose weight is less than 150 pounds. And for someone whose weight is greater than 150 pounds, he would be better off with a dirt bike with 250cc to 450cc engine. One thing to keep in mind is that the dirt bike is not a good choice for inexperienced riders.
How to make your dirt bike lighter
Less fuel in the tank
When you are racing, you don’t need a full tank of gas. Because it is highly unlikely that you will run out of gas before you cross the finish line.
You can still figure out the length of the race and what sort of mileage you can achieve on the track. Then, fill up your dirt bike accordingly. The amount of tank you leave out unfilled will make the bike that much lighter. So, if the track won’t require a full tank, just fill your gas tank with the required gas and your bike will be much lighter.
Use Titanium parts
Replace the replaceable parts of your dirt bike such as screws, bolts, and nuts with titanium parts. The downside to these upgraded parts is the cost. It is no surprise that titanium parts are going to cost a good amount of money. So, you should consider and compare your cost and benefits and then whether the upgrade is suitable for you.
Use lighter plastic
Dirt bikes have plastic parts. So, your bike might have the plastic it came with or you have replaced them for aesthetic reasons. Whichever it is, you can change them with lighter versions of plastic. You can find specific plastic that is made for racing. They are much lighter and add minimal weight and they are aerodynamically shaped.
Apart from weighing less, they also look amazing and shape your bike in a way that it resists the air less when you are going at a high speed. However, these perks will cost you some good money. So, it’s up to you whether you are ready to spend some bucks to make your dirt bike lighter.
Replace the exhaust
Replacing the exhaust is one of the most common and obvious choices when it comes to making your dirt bike lighter. The exhaust is typically made of stainless steel or aluminum, which adds a good amount of weight to the bike. The good news is you can replace it with titanium to lessen the weight.
Now, you might be wondering “isn’t aluminum lighter than titanium”? Yes, it is. So, wouldn’t the exhaust made out of titanium be heavier? No.
See, if the exhaust made out of aluminum and the one made of titanium have the same exact measurement, then the lighter one will be the one made of aluminum.
But the titanium exhaust will be lighter because it isn’t built like the aluminum one. Titanium is much stronger, meaning the built of titanium exhaust can be different, thinner, and lighter in specifications. Therefore, making the titanium exhaust lighter than the aluminum one.
