S&S Cycle T111 Twin Cam Engine for 1999-2017 Harley-Davidson Dyna and Touring

S&S Cycle T111 Twin Cam Engine for 1999-2017 Harley-Davidson Dyna and Touring

The S&S T111 turns a Twin Cam Dyna or Touring into a different machine — one that pulls harder out of corners, settles into a confident cruise at any highway speed, and reminds you on every ride why you chose a V-twin in the first place. A shorter-than-stock profile and easy-start gear drive cams mean the installation is clean and the first kickover is anything but dramatic.
