This is an original vintage OEM factory cylinder head made for Yamaha small-displacement two-stroke motorcycle engines. Cast from durable aluminum alloy, it uses an air-cooled design with deep symmetric cross-pattern fins to help move heat away from the combustion chamber. The head includes four mounting stud holes positioned around a central threaded spark plug port. It is suitable for restorers and mechanics maintaining classic lightweight Yamaha engines from the late 1960s and early 1970s.
