I had a pair of IMS Pro Series footpegs meant for Kawasaki '99-01 KX125 250 (#293112-4) laying around which I had purchased for a previous project of mine but never ended up using them. After getting rid of that bike I stored them for later use. At one point I had them for sale too but after time went by and I still had them I decided to utilize them in this build.
I designed a pair of brackets to be able to fit them to frame of my GT250K with help of four weldable inserts and M8 bolts. Inserts were turned in lathe out of 18 mm round steel bar and parts of brackets cut out of 6 mm steel sheet using water jet cutter and welded together.

Since water jet cutter tends to leave chamfers to holes I decided to make them bit smaller and drill them to right size after cutting. I did that in two stages. First time to 8 mm and after mocking up and welding M8 inserts to frame to 9 mm. 8 mm holes allowed me to center inserts perfectly to brackets. They would have been too tight for M8 bolts after painting so I decided to drill them afterwards to 1 mm oversize. I will powder coat both footpegs and brackets later once I have all the other parts such as side stand etc. ready for that as well.
