Piston set has a compression ratio of 9.3:1 and includes rings.\n\u003cp\u003eThe Keith Black KB348.010 95-inch Twin Cam piston set features a hypereutectic alloy cast in a permanent steel mold. This construction supports a lightweight piston design intended to help produce more power, improve fuel economy, and provide long service life. The pistons are .010 oversize for a 3.875-inch bore and provide a 9.3:1 compression ratio.\u003c\/p\u003e\u003cp\u003eThe alloy's low heat transfer helps keep the skirts cooler, minimizing piston expansion. Combined with high compression ring placement, the design is intended to support power and economy while reducing detonation and increasing top ring temperature. The Keith Black KB348.010 fits 2007–2016 Harley-Davidson FXST models, including 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, and 2016 applications.\u003c\/p\u003e\u003cp\u003eFor proper break-in of new pistons and rings, run the engine at moderate speeds for at least 500 miles and avoid excessive operation in lower gears.
