Catrina motosurf’s Honda CB750
From a Mexican builder who was inspired to build his first bike by doing exactly what you’re doing right now—i.e., looking at a bunch of bikes on the Internet—this Honda scrambler-slash-tracker is a hodgepodge of parts...but it works. The engine was rebuilt and converted to modern electronics, then the frame was stripped down and re-fitted with parts from Honda, Kawasaki, and Yamaha. Basically, he took what he could get, and made it work beautifully. After that, it was a matter of extreme attention to detail, like matching the stitching on the seat to the paint on the tank, and replacing every bolt on the engine with stainless steel bits.
