We had a fully automatic pit bike and as soon as my kid grew out of it, we decided to use the engine for this trike. Most of the stuff on this drift trike was custom made or modified. Here are some measurements of the frame;
Two main pipes that go from front fork are 60 inches long(152.5cm). They run parallel to each other and the distance between them is 8 inches(20.32cm). From the head tube (front fork) at 7 inch mark (17.78cm) made a 45 degree bend on both sides. From that point go down 22 inches(55.88cm) and make a 65 degree bend on both sides. Two other pipes that are on opposite side of each other are made for reinforcing the frame and to stand on them. each pipe is 26 inches long (66.04cm) and bent 45 degrees at around 9 inch(22.86cm) mark.
All these measurements are approximate and can be altered to your size and preference. This trike was made without any plans so if i could do it than you should be able to make one as well. Good luck.
