S&S Cycle P93 Panhead Engine for 1970-1999 Custom Harley-Davidson Big Twin Chassis
The S&S P93 gives custom builders the look that defined an era with the engineering to back it up. It carries all the visual character of the original Panhead — the pan-shaped rocker covers, the classic proportions — but underneath runs a fully modern hydraulic valve train, electronic ignition, and 93 cubic inches of S&S-built motivation that is designed to be ridden hard and ridden often.
