A Look Inside Harleys 120R Engine Oe Vs Se Cams
18 On the left is an SE 266E cam and on the right is an OE cam. The SE 266E cams have a modern lobe design that allows for higher valve lift for a given duration. The cams provide 0.658-inch valve lift for the intake and exhaust. The cams offer good part throttle ridability while also providing excellent wide-open power due its enhanced overlap design. The lower lobe also has a smaller diameter profile to allow for clearance.
