I was looking for a way to relocated the foot controls on a motorcycle that I was building.  After researching what was currently available and not being happy with what I found, I decided to design my own.  After taking all the necessary measurements and creating the needed specs, I designed the parts using a CAD program on my Mac.  I fashioned a prototype out of some spare plastic sheet I had laying around to ensure the accuracy of the design, then used my contacts to find a local company willing to produce the parts.
