Cylinder head work at APE is done on the latest state-of-the-art equipment. We have facilities to completely rebuild all motorcycle heads. As a manufacturer of high-performance cylinder head components, we have all of the parts in stock: bronze valve guides, stainless steel valves, valve springs, titanium retainers and more. Everything we need to complete your job without waiting on the parts - which slows down most shops.

APE's super state-of-the-art Serdi cylinder head machine, with triple-float head for the most accurate valve seats possible. The Serdi uses a multi-angle carbide cutter that has the seat shape ground into it. This ensures that all angles are exactly the same - all seat widths are exactly the same. A perfect valve job.

APE also offers cylinder head packages for offroad bikes/ATVs
