Athena Engine

58 Produkte

Athena's Harley-Davidson engine catalogue extends past sealing into the cylinder kits, big-bore upgrades, and rebuild components that the Italian manufacturer has been engineering for V-twin platforms since 1973. The Alonte factory uses the same metallurgy and tolerance control that puts Athena into OEM supply to Ducati, KTM, Piaggio, and Triumph — meaning a top-end kit with Athena's name on it is built to the standards used by manufacturers building bikes from new, not just by aftermarket workshops piecing them back together. For Sportster XL owners, that includes drop-in cylinder and piston combinations that target reliable displacement increases without rebalancing the bottom end. For Twin Cam and Milwaukee-Eight builds, it covers complete top-end rebuild kits with cylinders, pistons, rings, and the gasket sets matched to the same tolerance stack. Older Evolution Big Twin and Shovelhead jobs get individual cylinders, pistons, and seals available as standalone components. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Athena across the engine catalogue for top-end refreshes and bore upgrades. Browse the full Athena Engine range below.
