SPI . SM-109728

Manufactured by SPI Includes piston, ring set, wrist pin, & circlips SPI pistons are engineered to provide the best possible path for combustion chamber heat transfer to the cylinder walls All SPI pistons, rings, pins, & circlips are manufactured to OEM specifications All individual components are interchangeable with original parts Piston weight is compatible with original piston Hyperdryve series pistons Hyperdryve pistons use an aluminum alloy which maintains it's high tensile strength up to 700 degrees F, which is 50% higher than a conventional cast piston. This high temperature resistance significantly improves fatigue strength and impact toughness, which means it will keep you riding longer and harder than the competition. Made in Taiwan A stock photo is used Piston is for standard bore size 77.25mm Fits models that use OEM# 2201559 2000 600 Touring 2005-2006 600 Touring 2003 600 XC Edge 2000-2005 600 XC SP 2002-2006 600 Classic 2001-2004 600 Classic Touring 2001-2004 600 Pro X 2004 600 Pro X2 2002-2007 600 RMK 2004-2007 600 Switchback 2006 600 HO Fusion 2007 600 HO IQ
