Most of us know S&S Cycle for its big bore Harley-Davidson clone engines, but many people don’t realize that the Wisconsin-based company also makes its own Knucklehead, Panhead and Shovelhead engines, with engines available to fit stock, era-correct Harley-Davidson frames and units that can be bolted into a late-model chassis, as well. All engines use upgraded S&S internals and electronic ignition, and Panhead engines (shown) use S&S’ new design cylinder heads. Comes with a 2-year warranty. Price: $7,995 (as shown). MC
