Important Fitment Information
Check the engine code before ordering. A pit-bike model may have been supplied with different engines during its production life or may have had an engine conversion.
This listing is for the YX150 / YX160 CRF-angle cylinder-head family. It should not be treated as a direct replacement for a Lifan 150 engine, KLX-angle head or Z155 head.
A YX-style head can be adapted to some Z155 applications only with additional compatibility work such as the correct inlet manifold arrangement and original Z155 cam sprocket. That is a conversion, not direct fitment, and Z155 models are therefore not advertised as direct-fit applications here.
Compare the casting, port angle, mounting points, cam arrangement and engine code with the existing cylinder head before installation.
