Derived from a race generation piston , the new Pro Series Pistons are braced internally and externally for strength , Performance , and stability. Purpose built for maximum reliable performance.
Love this thing! The higher compression (12.8:1) added so much bottom end power in my KFX450. Definitely worth the increase in HP across the rev.
