Selfmade racecar from Germany

A completely self build singleseater racecar. Weldet steel Tubeframe with a Honda cbr 600 (pc19) engine (about 90hp). Rear differential from a Mercedes 210d modified for chain drive. Sequential gearbox and a seat from a go-cart. Self build steering transmition for super direct steering inputs. Overall weight of 285 kg! A lot of fun to drive, amazing handling and hunderets of hours of building. But not allowed to be driven on German roads (really sad about that).
