However, the rider can adjust the height as per the rider’s need. With a few simple adjustments to the seat, suspension, or handlebars, the rider can adjust the bike’s height in accordance with his/her height.
Tips to lower the dirt bike height
The bike’s height can be easily altered with adjustments in the bike’s seat height. So, to lower the bike’s height, lowering the bike’s seat can benefit the rider. Here are some simple ways to reduce the bike’s height:
- Removing some foam from the seat is the simplest way to reduce the bike’s height. Cutting some extra foam from the seat pad will not add discomfort to your riding.
- Replace the seat foam with some softer foam, so when you are on the seat, the foam will compress, giving you the required height adjustments.
- Making holes in the seat can also aid in reducing the height, as the seat will shrink whenever you sit.
- Setting the sag on the bike’s rear suspension can also reduce the bike’s height. So, adjusting the spring at the rear suspension could help you find the appropriate height. But this method can lead to compromise in the steering performance.
Tips for raising the dirt bike height
If you are taller and the dirt bike’s height cannot meet your riding needs, you can add a few more inches to have a better riding experience. Here are some tips for raising the bike’s height:
- Getting taller seat foam can help you raise your height by spending a few dollars. It will let you increase the height of your bike by 2 inches without compromising on steering dynamics.
- Adding a bit of the sag setting on the bike’s rear suspension can aid in raising the bike’s height. But this method can affect the bike’s steering performance.
- Using taller handlebars also helps in the bike’s height raise. This method does not increase the seat height but provides more space to scoot forward on the seat to have a comfortable ride. This method can affect your handling of the bike.

Many riders prefer trail bikes. These bikes are good for covering medium to long-distance rough terrain. The bikes provide better ride quality with smoother power output, low seat height, and softer suspension.
The trail bikes are cheaper and good for beginners who don’t need the latest tech and features.
- Enduro bike:
Enduro bikes are preferred for racing on enduros and scramble-type events. Though the enduro bikes are a bit costlier but entail ample technology that motocross bikes have. In simple words, it can be said that the enduro bikes are a blend of motocross bikes and trail bikes.
- Dual-sport bike:
As the name implies, dual means double, so dual-sport bikes are good to go on rough trails and street legal. The dual-sport tires let the rider ride the bike on the rugged trails and the roads.
There are knobby tires on the bike, but they are less aggressive than those specially designed for dirt riding.
- Trial dirt bike:
The trial bikes are different from those mentioned in the list. These bikes are specially used for rides to test the riders’ technical ability and skill, not speed.
The rider, while riding, pays attention to clutch and throttle to tackle obstacles (impossible on a regular dirt bike). Sp, these bikes are specially for obstacle climbing only. The trial bikes have a different set-up form other dirt bike.
- Supermoto bike:
The supermoto bikes, originating from an off-road bike, the bike is modified and designed to make them street legal. The full street wheels of the bike make it street-legal to ride.
The supermoto bikes, when compared to the street bikes, are lightweight and agile and are suitable for tracks having dirt and tar.
- Hill climb dirt bike:
These bikes are designed to meet hill riding conditions, thus making hill riding easier. As good to go on hills, such bikes are perfect for hill climb competitions where the setup contains steep hills with negligible to no run-up.
The hill climb bikes entail more power than the typical dirt bike, so they are dangerous for average riders to handle.
- Flat track dirt bike:
This type of dirt bike is meant for flat surfaces—offering high speed and maximum grip. The lowered suspension and the flat-track tires enable the rider to offer a hassle-free ride around an oval track.
Choosing the right size
Now comes choosing the right size, which is very crucial. It’s essential to consider your age, height, and weight before considering any dirt bike. Opting for any random bike can lead to choosing the wrong bike, which may not be comfortable to ride and maybe unsafe.
It is always advisable to visit the dealer shop and sit on the bike; if your toe and feet balls touch the ground, you are good to go. But if your footrest is flat on the surface, it is not a good sign. It means the bike is short for you, which will exert pressure on the suspension, thus hindering the ride quality.
The same goes with the weight. If you are tall and heavily built, you will need a better suspension for better handling on rough surfaces.
Choosing between 2-stroke and 4-stroke
Strokes also play a significant role in choosing the dirt bike. The two-stroke bikes can deliver more torque and engine capacity than four-strokes, and the two-strokes are lighter than the same-sized four-stroke bike.
A 2-stroke bike has a steep but narrow torque curve, and 4-stroke has a more linear torque curve. So, many beginners prefer a 4-stroke bike as it is easier to learn and does not involve much clutch slipping to get into the powerband.
The four-stroke bikes offer more engine braking, making them better for very steep downhills.
