The Cylinder Works +3mm Big Bore Complete Kit is a ready-to-install upgrade for the 2006-2014 Yamaha Raptor 700 (YFM 700R), increasing displacement to 727cc with a 105mm bore and 9.2:1 compression ratio. This kit includes a cylinder, matched Vertex piston, rings, pin, clips, and gaskets. The cylinder features a nickel silicon carbide-plated sleeve for durability and reduced friction, ensuring long life and improved performance. It is designed to look like an OEM cylinder and does not require additional machine work (unless otherwise noted). This kit provides a direct bolt-on solution for riders looking for increased power and reliability while maintaining OEM-like appearance and fitment. Replacement pistons, gaskets, and ring sets are available separately.
