Hemi Dome Piston Kit (KB297.STD) by KB Performance Motorcycle®. Hypereutectic Alloy is a cast 16% high silicon content material that has very high thermal barrier properties along with a low thermal expansion rate. This alloy is perfectly suited for an air-cooled engine. Tight piston-tocylinder clearances are used to achieve better ring seal and a quiet running engine. Hypereutectics are best suited for Street Bikes using stock or mild compression ratios to 10.5:1 running on pump fuel. With the high silicon content, these pistons will resist skirt wear the best. Models that end in a "C" come with Anti-Friction skirt coating.
