Cylinders for X-Wedge®. The S&S X-Wedge engine is different from anything we have offered before. Developing a new design allowed us to incorporate a number of useful new features, and one of our priorities early on in the design process was to make this engine easy to service. The front and rear cylinders and pistons are interchangeable, which means that we don’t have to sell cylinders or pistons in sets. In addition, the diameter of the X-Wedge pistons is held to such a tight tolerance that it is not necessary to measure each pistons and fit a cylinder to it. Cylinders can be honed to the specified size and any pistons of the correct oversize will fit with the correct clearance.
