KB Hypereutectic alloy pistons are cast with a 16% high silicon content that has very high thermal barrier properties along with a low thermal expansion rate, allowing tight piston to cylinder wall clearances. This makes them ideal for air-cooled engines, offering optimal ring seal, quieter engine running and reduced wear. Hypereutectics are best suited for stock or mild compression ratios up to 10.5:1 running on pump fuel.

This is the 2nd set of these pistons used in this Harley. They ran great for more than ten years before the front piston burned a hole in it. Don't have any idea why that happened but it must have been spark knock.

These are Keith Black pistons and rings. All are first class products and good manufacturer instructions. I will definitely buy again.
