After reading, I hope that you will have your first and best motorcycle ever. Let’s get started!

How To Build A Dirt Bike?

What you need to follow this tutorial:

  • A dirt bike frame
  • A small or medium-sized dirt bike engine ( it can be 125 to 750 cc, including cylinder seals, oil seals, and gasket)
  • Sandpaper and cleaning tools
  • Some replacing components (suspension, sprocket, rocker arm, wheels, or anything that you find it too old and want to replace)
  • Screwdrivers

If you already have an old dirt bike, which can be found in junkyards, old component stores, or auto auctions, you may not need to find an engine anymore. Unless it is too old and cannot be used, you should replace it. Otherwise, just disassemble it along with other parts, clean them, and put them back together. I will show you how to build a dirt bike from scratch:

Step 1: Disassemble the components from the frame

No matter what you find, an old dirt bike or a dirt bike frame and spare parts, they all need cleaning up before being attached with one another. Disassembling them is the easiest way to do that, and you can also check if anything should be replaced.

Step 2: Clean the components

As a result of the last step, cleaning your spare parts is an essential thing to do. You can use sandpaper to rub all the rusty spots and make the components look newer and shinier. Then, take a wet cloth and clean the surface of them. All of the oil and dirt will come out after this step. Remember to wear gloves and a mask while cleaning because the dirty parts may harm your skin.

Step 3: Start assembling the parts

  • The engine:

If you have an available driving force, doing this step is unnecessary. But if you have not any and want to replace some old parts, you need to know what they are and how to replace them. A cylinder is the central part of the engine and the primary motor that helps your bike start.

A gasket lies between the cylinder and engine block, which prevents the oil from spilling into the cylinder. A piston ring aims to block the combustion part and cool the engine. And there are so much more components that you need to discover. In case you don’t know where to find, this video will help you do that:

  • The tires:

These are the easiest components that you can install. Even an untrained person can do it. Take a tire out and roll it in place. Then, lift the tire up, which is to make it stay on the rim, by sliding your foot under it. Finally, put the hub through its center and stabilize it with a seal.

  • The brakes:

As you already know, there are two brakes, one in the front and another at the back. They are the most crucial parts to guarantee your safety so be careful when installing them. Make sure you choose the right cable by checking the nipples at the end of it. If it fits your handlebar, it is accepted. Just connect the right brake cable with the back wheel and the left one with the front, and you are done. If you are left-handed, you can do the opposite way.

Step 4: Test your dirt bike

I have just introduced you what you need to install in the frame of your bike. After you have done, it’s time to test the system. Because it’s a dirt bike, it’s best to do this step on earth. If you have dirt backyard, it will be fantastic. Otherwise, you can find a race track for motorcycles. There will be a wide area for you to test your bike.

When you do it in the backyard, remember to wet the area where you want to ride. You will see how well your brakes perform and how your engine works on dirt as well as faces with a slippery surface. To get more details, you can watch this video:

And those are the fundamental steps for you to build your dirt bike. If you have any difficulties, ask for help. Don’t do it all alone when it exceeds your capability. To keep following my writing, you should remember those steps because they are the necessary skills to build other types of bikes. I will show you some differences of among the kinds in the next parts.

How To Build A Mini Bike?

A mini bike won’t give you a hard time because it’s small and simpler than a dirt bike. These are what you will need:

  • A mini bike frame, which you can get from junkyards, Craigslist, or eBay.
  • A small-sized engine ( 125 to 350 cc)
  • Sandpaper and cleaning tools• Some replacing components (suspension, torque, rocker arm, wheels, chain, clutch, etc.)
  • Screwdrivers

You will repeat the steps of building a dirt bike to have a mini bike. Just remember there are plenty types of frames so you should choose one first and then pick an engine with an appropriate size. And due to the bike’s small size, the chain can be a little longer than you expect. Therefore, measuring the distance between the clutches before cutting the chain will be necessary. Just grasp a screwdriver and get to work.

How To Build A Bobber?

I would like to introduce how you can create one of the most classic motorcycles in this article today. It’s a bobber, which has a history of development from the 1930s to 1990s. It’s an idea of replacing some of the components, including fenders, signals for turning, and brakes, to make the motorbike lighter and can run faster on the racing track. To build a bobber, you are going to need:

  • A bobber frame, which you can find in junkyards, Craigslist, or Amazon.
  • A medium-sized engine ( 350 to 750 cc)
  • Sandpaper and cleaning tools
  • Some replacing components (fenders, signals, brakes, torque, rocker arm, wheels, and anything that makes the bike lighter, etc.)
  • Screwdrivers

There are not many differences between building a dirt bike and a bobber besides choosing the spare parts. Despite replacing several components to reduce the weight, a bobber still keeps the original frame of its manufacture. So you need to have proper measurements and understandings about your bike to choose the correct parts.

How To Build A Chopper?

And this last part is a chopper. Many people still mistake between a bobber and a chopper because they have numerous similarities. The simple distinction you can use to tell them apart is their frames. A bobber keeps the original frame from the factory but a chopper does not. It uses a modified frame and has more chrome than a bobber.

Therefore, to find out which motorcycle you like, you need to know which style you want. With a bobber, you are not allowed to be creative much due to its fixed frame. However, a chopper will let you develop your creativity and think out of the box.

The choice depends on you. Right now, just know that building a chopper will take the major steps similar to building a dirt bike. You can have some more creative ideas if you like. And these are what you will need:

  • A chopper frame, which you can find anywhere and even make one.
  • A medium-sized engine ( 350 to 750 cc)
  • Sandpaper and cleaning tools• Some replacing components (fenders, signals, brakes, torque, rocker arm, wheels, and so on)
  • Screwdrivers
