How to Build a Motorcycle Jig

Motorcycle jigs are used as a support system for motorcycle frames. It keeps the parts of the motorcycle frame in place when it is time for fitting and tack welding. They are normally sold in motorcycle shops but if you decide to build one on your own successfully it will require the proper tools and materials. The steps below will give you information as to how to go about creating a motorcycle jig on your own.

Tools required

  • Welder (Welding torch)

Materials required

  • Steel
  • Set screws
  • 5-inch steel mill channel
  • 1/8 inch wall steel tubing


  1. Find a source that can provide motorcycle jig designs/ templates that you can be used as a guideline for making your own.
  2. Take the 1/8-inch steel tubing to start assembling the neck jig. This is normally 2*3 inches depending on the motorcycle jig design you choose. Clamp two plates to the 5-inch steel post to allow vertical adjustment of the neck.
  3. Use the ¼ inch steel tubing (which is usually 2*4 inches) to build an axle post. Connect the axle to the plates using axle adjustment slots. Secure the axle with spaces and shaft collars. The axle posts should be made to move in any direction as required.
  4. Take a ½ inch of steel plate and a piece of square tube and use the welding torch to weld them together. This will allow the plate to move or to jack up vertically whatever part is necessary. Work on the engine fixture. Start with the lower rails by setting it up with steel stubbing that is 1¼ inches. Measure your engine area correctly to allow room for seating bolts and other attachments. The engine bar should be made of a 1*4 inch steel bar. Make two lower rails that have spacers (1¼) between them.
  5. Carefully weld the rear axle to the bike frame and re-measure and dry-fit the rear wheel before completing the weld.
  6. Let a threaded rod pass through the channels and use an angle and nut to secure the bolt then screw the engine plate to the fixture using four setscrew jacks. Use a drill to make these set screws. This should be placed at each corner of the engine plate.
  7. When everything is assembled you should test the structure to see if there are any stress points, and then paint it with high-temperature, rust-proof primer putting on a couple of coats to give it a final finish.

Tips and Warning

  • When making your motorcycle jig take into consideration that some bikes may require a specific type of jig. Find out what size frame you will be using before you build the motorcycle jig so it will fit correctly.
  • Properly test the welds before building the motorcycle frame. Do a test on parts that you have welded to test the strength. You should probably consider taking a welding course before attempting to make a motorcycle jig or get a professional to do the job.
