S&S® T111 Motorcycle Engine

S&S T111 engine for twin cam motorcycles

Those used to looking at dyno charts of high performance engines may wonder why the T111 does not make more horsepower on the top end. That’s because it is a bona fide touring engine. Thanks to the S&S® Super E carb, moderate compression ratio, and mild cams, it has a lot of torque and a broad power curve making passing vehicles, climbing hills, and accelerating up to highway speed as simple as twisting the throttle. We recommend the S&S T124 engine for customers who are looking for big horsepower numbers.

The new T111 is a powerful yet quiet motorcycle engine perfect for touring riders. A practical stroke, less aggressive touring cam, and nearly silent valve train create a torquey, smooth power band – making your bike a pleasure to ride for long distances. Lower cost and superior engine life.

Fitment

The T111 will only fit in place of 1999-’05 fuel injected engines and 1999-’06 carbureted engines

S&S does not offer full replacement engines for 2006 Dyna® models, any 2007-up models, or any counterbalanced engines, such as Twin Cam 88B™. However, see our Power Kits starting on page 1-22 for power-enhancing modifications to these models.
