ENGINE DIMENSIONS
Some S&S engines are taller than stock engines. These diagrams show the dimensions of various S&S engines. This information will be most
useful to customers building custom motorcycles with after market frames. Note that KN-Series engines may be used in 1948-99 style frames if
the provided spacer is installed under the front motor mount.
