55CI OHV Twin

Our Harley-Davidson 55CI OHV Twin Parts & Accessories range covers the 883cc overhead-valve four-cycle twin engine that powered early Sportster models from 1957 onward. As an Iron City authorised Harley-Davidson dealer in Leeds, we stock genuine and aftermarket parts for the Ironhead-era 55-cubic-inch OHV engine and the bikes it powered. You will find pistons, gaskets, valve train components, primary drive parts, exhaust pipes, carburettor kits and engine dress-up hardware for these classic air-cooled twins. Whether you are rebuilding a numbers-matching Ironhead or sourcing service parts to keep one running, our team can help you find the correct components for your year and model.
