Dirt bikes are used for off-road racing. They are equipped with knobby tires and some type of suspension. A dirt bike must be able to handle extreme bumps, jumps, and drops. They have a very high power-to-weight ratio compared to most other motorcycles because they typically weigh about 100 pounds (45 kg) or less and produce 15–30 horsepower (11–22 kW). Modern Suzuki Hayabusa motorcycle has an output of 197 horsepower.

Most dirt bikes fall into the “class” category of off-road motorcycles according to the Fédération Internationale de Motocyclisme (FIM), a federation that governs international competitive motorcycle racing events such as the World Superbike Championship, which consists of classes: 125cc (the smallest displacement, which is this article’s focus), 250cc, 350cc, 450cc, and the top class 1,000cc.
125CC Dirt Bike:
The displacement of a dirt bike engine is its piston bore measurement multiplied by the stroke length. A 125cc dirt bike has a piston bore of about 54 millimeters (mm) and a stroke length of 50 mm. This gives a total displacement of 2,700 cubic centimeters (cc). Dirt bikes with engines in the 125–250 cc range are considered “small-bore” and are typically used by younger riders. They offer good performance on tight, twisty trails while still being manageable enough to not require too much experience or skill to operate. They also tend to be less expensive than larger displacement dirt bikes, which can cost anywhere from $6,000 to $10,000.
The Honda CRF125F is a popular small-bore dirt bike that has been around for many years. It’s a great starter bike for riders who are just getting into the sport and want to learn the basics of off-road riding. The CRF125F is a reliable bike that is easy to maintain, and it can be ridden by riders as young as six years old.
250CC Dirt Bike:
If you’re looking for something with a bit more power than a 125cc dirt bike, there are plenty of options available in the 250cc range. The Yamaha WR250F is a good choice for riders who want a versatile bike that is also lightweight. It has a very good suspension and includes a skid plate to protect it from crashes.
The KTM XC250 is an excellent choice for serious off-road riders as well as those looking for a durable bike that can be used for just about any type of riding. It’s at home on trails, in water, and even has enough power to pull wheelies.
Most riders want a dirt bike that will provide them with plenty of speed and excitement on the trail. Fortunately, there are classes available that offer not only more power than 125cc bikes but also larger displacements.
450CC Dirt Bike:
The 450cc class is fast becoming one of the most popular in off-road motorcycle racing because they do not require much maintenance or attention when compared to the 1,000cc bikes. The Suzuki DR-Z400SM is a great choice for riders who want a bike that is capable of doing it all. It’s perfect for tight trails and can handle jumps and drops with ease. The Yamaha WR450F is another excellent option in the 450cc class. It’s been updated for the 2017 model year and offers more power and better handling than ever before.
If you’re looking for something really exciting, the KTM 450 SX-F is worth a look. This bike was designed for pure racing performance and has won numerous championships around the world. It’s not for the faint of heart.
1000CC Dirt Bike:
Of course, if you have the money, you can’t go wrong with a top-of-the-line 1,000cc dirt bike. The Honda CRF1000L Africa Twin is a perfect example. This bike was designed for long-distance off-road travel and can handle just about any terrain you might encounter. It’s also comfortable enough to be ridden on the street.
