We designed our ST4 off road vehicle to be simple for you to build at home using your own welder, tube bender and fabrication tools. ST4 fabrication plans are laid out in a logical step-by-step format.

We explain all the necessary fabrication steps that you need to do to successfully construct this premium off road vehicle. Our fabrication plans include both metric and imperial measurements in millimeters and inches. We show you how to cut and bend individual tubes, how to prepare the ends of tubes to accurately fit together, then how to weld individual tubes into an overall chassis frame. Our fabrication plans also include measured fabrication and machining drawings for constructing the entire front and rear suspension systems including detailed parts lists for all the parts you need to purchase. We also show you how to build the robust rack and pinion steering system. You can purchase and install a variety of motorcycle engines. We do not show you how to install the engine, as every engine has different mounting points, however, we have designed the engine compartment of ST4 to accept just about any size of motorcycle engine.

We have included files so you can have some parts precision laser cut. DXF files are two dimensional CAD (computer aided design) patterns that all laser cutting shops use worldwide to create precision laser cut steel plates.

This saves you time and money. Your local laser cutting shop does not have to redraw any parts. You simply give them the DXF files supplied with your fabrication package and they can reproduce exact parts for you. All our flat steel plates are designed to be self-jigging. We have designed slots with mating tabs in our steel plates so they fit precisely together. There is no guessing how parts fit together, as we have done all the hard work for you.

We also provide you with information on where you can purchase all of the bolt-on parts you will need. ST4 Fabrication Plans Package includes: 100 page Instruction Manual with measured drawings in PDF format, 40 DXF files (generic CAD) for all flat steel laser cut plates, 32 CAD renderings in JPEG format, 4 CAD models (uneditable) in DWF format (link to free CAD viewer) including 3D CAD model of entire vehicle, chassis weldment, front suspension, rear suspension & drive system, Parts Lists including Steel Order List, Nuts & Bolts List, Purchased Parts List in PDF & XLS formats c/w parts suppliers, part numbers, quantities, contact info.
