Description

A quality cylinder head is the foundation of engine performance—it controls airflow, combustion efficiency, and overall power delivery. The S&S Cycle 90-1499 arrives completely assembled and tested, eliminating the guesswork and machine shop costs typical with core rebuilds. This is a bolt-on solution for builders who demand precision engineering and want to spend their time tuning, not troubleshooting.

What you're getting here is a fully dressed head with premium components already installed and validated. No surprises, no missing pieces, no second guessing your valve spring rates or seat concentricity. Just bolt it on, use your existing manifolds, and get back to making power.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
