A couple of vintage race bikes from down under. John Trease Engineering built some pretty wild stuff until mr. Trease passed away in 2017. These are based on Ironhead Sportsters, but with some significant changes. The cases are homemade cast magnesium, the cylinders are homemade as well, cast in aluminum, and the heads are from a Panhead, with the front one turned around backwards. They have Yamaha transmissions, ignition is twin plug fired by a pair of magnetos, and they run on methanol. At 88 cubic inches, they reportedly made over 140 hp on a chassis dyno. His son has drug them out of storage and has been racing them again. Pretty cool stuff.
