Why Should You Convert Dirt Bike to Supermoto?

Many people choose to convert their dirt bike into a supermoto because it allows them to enjoy the best of both worlds. Supermotos are designed to be ridden on both paved and unpaved surfaces, which means that you can take your bike off-road without any worries.

In addition, supermotos typically have larger wheels than dirt bikes. This provides more stability and makes them easier to handle on the road. Therefore, converting a dirt bike to a supermoto is not a difficult task. However, it is important to follow the instructions carefully to avoid damaging your bike.

10 Effective Methods on How to Convert Dirt Bike to Supermoto:

1. Choose the Right Bike:

The first step in converting your dirt bike to a supermoto is to choose the right bike. Not all dirt bikes are created equal, and some are better suited for conversion than others. When choosing a bike, you should consider the engine size, weight, suspension, and tires.

2. Modify the Suspension:

One of the most important aspects of converting a dirt bike to a supermoto is modifying the suspension. This is because a supermoto’s increased weight and speed will put more stress on the suspension than on a dirt bike. If the suspension of a dirtbike is not properly modified, it can lead to a dangerous situation.

3. Change the Tires:

Another important aspect of converting a dirt bike to a supermoto is changing the tires. The increased weight of a supermoto (due to the larger engine) means that it needs different tires than a dirt bike. Supermoto tires are designed for both on and off-road use to handle the increased weight and speed of a supermoto. You’ll need to purchase both front and rear supermoto tires before making the switch.

4. Install Supermoto Wheels:

Installing supermoto wheels is relatively simple, but it’s important to ensure they’re installed correctly. First, remove the front and rear wheels from your dirt bike. Next, install the supermoto front wheel, ensuring that the axle is aligned correctly. Finally, install the supermoto rear wheel, making sure that the axle is aligned correctly.

5. Install Supermoto Brakes:

Installing supermoto brakes is another important aspect of converting a dirt bike to a supermoto. A supermoto bike’s increased weight and speed mean that more powerful brakes are necessary to maintain control and safety. There are many different brake kits available on the market, so it is important to research to find the kit that best suits your needs.

6. Modify the Wheelbase:

Modifying the wheelbase is one of the most important aspects of converting your dirt bike to a supermoto. Changing the wheelbase will increase stability and traction while cornering and make your bike more flickable overall. The ideal wheelbase for a supermoto is between 1250mm and 1350mm. You will need to either shorten or lengthen your bike’s swing arm to achieve this.

7. Rejet or Reprogram the Carburetor:

A Supermoto bike’s increased weight and speed mean that the carburetor needs to be rejetted or reprogrammed to provide the correct amount of fuel. This is an important step in the conversion process, as it will ensure that your bike runs correctly and doesn’t experience any issues due to the increased stress on the engine.

8. Lower the Bike:

Lowering the bike is another important aspect of converting a dirt bike to a supermoto. By lowering the bike, you will increase stability and traction while cornering. The ideal height for a supermoto is somewhere between 10mm and 20mm lower than stock. You will need to adjust the front and rear suspension to lower your bike.

9. Exhaust Modification:

A Supermoto needs a quiet exhaust so it can be ridden on the street without getting noise complaints. The best way to do this is to replace the stock exhaust with a USFS-approved spark arrestor. These are available from many aftermarket companies, and they will usually come with all the necessary hardware for installation.

10. Clutching and Gearing Changes:

The increased speed and weight of a supermoto bike mean that the clutch and gears need to be changed to withstand the extra strain. As a result, heavier duty clutches and stronger gear sets are a must, and it is also recommended to change the final drive ratio to something shorter (higher numerically) to make use of the extra power.

2. Increased Stability and Traction:

A converted dirt bike’s increased stability and traction will make it easier to corner and handle at high speeds. This is thanks to the changes in wheelbase and suspension.

3. More Flickable and Agile:

A converted dirt bike will be more flick-able and agile thanks to the changes in suspension and wheelbase. This makes it easier to change direction and avoid obstacles while riding.

4. More Ground Clearance:

The increased ground clearance of a converted dirt bike will make it easier to ride over obstacles and rough terrain. This is thanks to the changes in suspension and tires. In addition, it will help the bike to avoid getting caught on rocks or roots.

5. Better Braking Performance:

The upgraded brakes of a converted dirt bike will provide the stopping power that is necessary for a street motorcycle. As a result, when you are riding your dirt bike on the road, you will be able to brake later and harder than you could before, which can help you avoid accidents.

6. More Power and Torque:

A converted dirt bike’s increased power and torque will make it easier to accelerate and climb hills. This is thanks to the larger and heavier tires, which provide more grip.

7. Better Handling:
