Good To Know

Q: Does this kit include rings and pin? A: Wiseco Std Piston Kits are typically supplied as a full assembly with piston, rings, pin, and clips, though contents can vary, so verify the listing contents before ordering.

Q: Will this fit my modified engine? A: This is a standard 79 mm bore, 12.5:1 compression ratio piston, so it fits factory-spec RS Venture cylinders; overbores or custom builds need a different sizing.
