CYLINDER HEADS


APE CYLINDER HEADS

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.


BRONZE VALVE SEATS

APE is the source for bronze valve seats for motorcycles. We supply them to many of the leading cylinder head shops and aftermarket manufactures. For more seat info, click here.

Bronze dissipates heat much quicker than steel which allows the valves to run cooler. Another benefit is that bronze does not beat the valve faces up like steel seats do. This is especially beneficial with titanium valves.
Available for stock size and oversize.

See HW-48 below for pricing
