T111 1999-2006 Big Twins, except for the 2006 Dyna models.

A lot of riders have already invested in performance upgrades for their stock engine by the time they are ready to move up to a complete big inch engine. Wouldn’t it be nice to be able to save some money by using some of those items on your new engine? Well now you can!

Star Racing is now offering S&S Cycle T-Series engines for 1999-’06 big twins without fuel or ignition systems. So if you have already added a performance carburetor or an EFI throttle body and tuner to your stock engine, you can use it on your new engine. A carb or throttle body that fits a stock engine will fit the new S&S engine because the heads are specially machined to compensate for the increased cylinder length so a stock length manifold will fit. If you’ve installed a performance ignition or EFI tuner, you can use it.

The 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.


New S&S T-Series Long Block engines don't come with a fuel or ignition system. Perfect for riders who already have a high performance ignition and carb or EFI throttle body and tuner. Since the heads are specially machined to fit a stock length manifold and breathing system, an air cleaner, carb, or throttle body that fit a stock engine will fit your new S&S engine!

S&S Warranty 2 years


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.
