16464-58 Cylinders for Ironhead Sportsters

These V-Twin replacement cylinders are a solid choice for any Ironhead Sportster rebuild where you want to maintain that classic stock displacement. Cast from a high-quality iron alloy, these standard replacement cylinders are designed to stand up to the heat and stress of an air-cooled engine. They come bored and honed to very close tolerances, but as any seasoned mechanic will tell you, it is always best practice to check your specific piston-to-cylinder clearances before final assembly due to slight variations in piston manufacturing. This specific cylinder replaces OEM 16464-58 and fits Sportster models. It is a reliable way to restore compression and performance to your vintage Ironhead without moving away from the original factory specifications.
