autoevolution 3 Mar 2021, 2:16 UTC · by 7 photos A little while back, Ickenham’s moto architects introduced us to a custom showstopper based on Kawasaki’s vicious GPZ550, a solid pick for workshops seeking to craft a breathtaking masterpiece to soothe just about any self-respecting rider’s soul. The stock bike is brought to life by an air-cooled DOHC inline-four powerplant, with two valves per cylinder and a displacement of 553cc. At a whopping 10,500 rpm, this bad boy will be more than happy to generate as much as 65 hp. At the same time, a generous torque output of up to 36 pound-feet (48 Nm) will be achieved at optimal revs.
