ENGINE KITS

APE is well known for its performance engine kits. Specially matched and selected componets that take the guess work out of selecting the right parts. APE Engine kits are offered in 2 styles; "Super Street and Road Race" kits for hot rod street use as well as road race competition. "Super Drag Racer" kits designed for all out drag race performance.

The street kits were designed by the APE engineers to provide the properly matched components for maximum street performance at the best possible price. We have chosen the most popular combinations of pistons and cams in designing these kits.

With the installation of these kits, the motor will respond dramatically to a performance cylinder head and carburation.

All kits are priced lower than if the components were purchased separately.

Listed on this page are examples of the most popular kits. Engine kit packages are
available for all models. Contact our tech department for kit info on your bike.
