      Fabrication Parts

      Are you going to build a custom Chopper or custom Bobber Motorcycle? We have Motorcycle Parts and Fabrication Parts so you can build that Custom Chopper or Bobber. With these custom motorcycle parts you can build your own motorcycle to your liking.

      How to build a custom motorcycle?

      Actually, you can turn almost any motorcycle into a custom motorcycle. Only some bikes will require more modification than others. But where do you start? What does it cost? How do you want it? What do you like? Which motorcycle are you going to use? Just a few questions that probably shoot through your head.

      What is your budget? Are you going to use a Harley Davidson motorcycle as a base? That is very nice but certainly not the cheapest way to rebuild a motorcycle. Before you start, make sure you have a clear idea of what style of motorcycle you like. 

      If you don't know what a Bobber or Chopper is you can read this blogpost about What's a Bobber and what's a Chopper?

      Make a clear plan for your motorcycle. Make sure you collect images of custom bikes that you like. Make a drawing or a collage of the images you have collected. This will give you a good idea of what your custom bike will look like. You can now make a list of all the things you want to change on your Chopper or Bobber. Maybe you want a different fuel tank, higher or wider handlebars, a custom exhaust, different footrests or forward controls. Or even a different oil tank, wider tires with wider fenders, better brakes, a smaller saddle or just a larger sprung motorcycle saddle. You may even want to modify the frame. You can widen or lengthen the swingarm or even remove the swingarm and modify the frame to an unsprung frame (Hardtail).

      Then start filtering by things you can do yourself, things you need to buy, and things you need to have done. This will give you a pretty good approximation of what the total cost will be for your project bike.

      Do you have a lot of experience rebuilding motorcycles? Then you know the tricks of the trade and don't have to shy away from anything.

      My advice, if you don't have much experience yet: Start small!

      Divide your big plans into smaller parts so it stays manageable for you. Many projects end up in a shed under a sheet because the owner started too enthusiastically and had no overview anymore. Start with a different fuel tank, for example. That gives your bike immediately a completely different look. If the tank does not look good, make sure you can go back to the original. So do not just grind all kinds of brackets and mounting points off your frame. Start bit by bit is my advice to the novice custom motorcycle builder. A big advantage is that you can just keep on riding your bike as opposed to a project that sits in the shed gathering dust for years.

      If the fuel tank is a successful project, you can continue with for example a custom exhaust. Do you need help with this? Let us know. 

      So: Make a plan!

      • What style of custom bikes do you like?
      • What base engine are you going to use for your custom Chopper or custom Bobber motorcycle?
      • Collect images and visualize what you want your bike to look like.
      • Make an overview of what you want to change on the bike:

        • What can you do yourself?
        • What can you buy?
        • What do you have to have done?
        • Divide the rebuilding of the engine into small parts!

      Success guaranteed with these Fabrication Parts!
