Description
The KZ1000’s inline-four was a beast from the factory, but factory pistons hit their limit once you push boost or higher RPMs. The Wiseco Big Bore Kit 72mm opens the door to real power gains—increased displacement means more air and fuel per cycle, translating directly to measurable horsepower without sacrificing the reliability your engine needs. With aerospace-grade forged aluminum pistons and a complete gasket set included, this is a bolt-together solution for serious KZ1000 builds.
