Upgrade your motorcycle engine with the Hastings Piston Rings designed specifically for 1200 cc Big Twin models. These rings include top compression rings, second compression rings, and oil control rings, providing a comprehensive set for optimal engine performance. The top compression rings feature a barrel face and are cast coated, enhancing heat transfer between the piston and cylinder wall to prevent overheating and maintain consistent performance. They also help control combustion chamber gases, ensuring efficient energy transfer to the crankshaft. The second compression rings are reverse torsional taper face rings, promoting side sealing to prevent oil from passing under or behind the ring, which improves oil economy and reduces emissions. Their reverse twist and taper-machined face replicate the scraping edge of torsional rings, offering effective sealing and durability. The oil control rings are a three-piece flex vent design, allowing for better conformability to the bore with a small cross-sectional area. This design ensures uniform pressure through four steel rails and two expanders, providing excellent oil control while reducing oil consumption. Manufactured in the USA, these rings are supplied in enough quantity for two pistons, with two rings per groove—except for the rails which include two rail rings per one expander ring. Proper installation of these rings will enhance your engine’s compression, reduce oil consumption, and improve overall reliability. Whether you're rebuilding or maintaining your motorcycle, these Hastings piston rings provide the quality and performance needed for reliable, long-lasting operation. Trust Hastings for durable engine components that meet or exceed OEM specifications, ensuring your bike runs smoothly and efficiently for miles to come.
