S&S Cycle 07-17 BT 117in Big Bore Cylinder Kit - Stone Gray

This big bore cylinder and piston kit contains S&S 4-1/8" bore cylinders and forged pistons, rings, wrist pins, head and base gaskets. The cylinders are machined with the stock bolt pattern and are intended for use in stock crankcases of 2007-'16 big twin engines. The stock 4-3/8" stroke and 4-1/8" bore result in a 117' displacement. Cylinder finish is a durable Stone Gray powder coat that matches CVO engine finish. For best performance, appropriate camshafts, performance air cleaner, performance exhaust and fuel system tuning are required.

• Crankcases must be bored to accept the larger 4-1/8" bore cylinders
