This SSP-G 67mm four-valve cylinder head is a Cygnus-style performance head for GY6 B-case four-stroke engine builds with 57mm stud spacing. Give your off-road project a four-valve top end with the cam, roller rockers, timing sprocket, studs, and nuts included. The head pairs a finned body with blue anodized head and cam covers for a distinctive finish. Designed for the 67mm application described as a 232cc build, this is a cylinder head assembly, not a complete displacement kit.

This product is intended for off-road use only. This product is not intended for use on public roads or land.

Model Fitment

Engine application Required configuration
GY6 QMI/QMJ 152/157 engine families B-case build with 57mm stud spacing and compatible 67mm cylinder configuration
Other compatible makes and models Same B-case, stud-spacing, cylinder, and valvetrain requirements

 

Check the engine code and measure the cylinder-stud spacing before ordering. A QMI/QMJ or 152/157 engine designation alone does not confirm B-case fitment. Match the cylinder configuration, cam-chain length, and installation clearances to your build. Cygnus-style describes the head design and does not establish direct Yamaha Cygnus fitment.
