TWIN CAM HARLEY ENGINE
Twin-Cam 111-124 HD Replacement Engine

S&S Cycle has a Harley replacement engine for bagger owners wanting more performance. This is great news for those of you wanting to go faster too. S&S Cycle is offering the T- Series Harley replacement engines for 2007-Up Twin Cam bikes. The S&S Cycle T111, T124 and T124LC Long Block Engines will bolt directly into your stock touring chassis with no modifications.

These Harley replacement engines are sold without the fuel system, so you can use what you have and save some money, or use any performance system you like. S&S Cycle recommends an S&S Cycle throttle body and the TTS VFI tuner!

The T111 Harley replacement engine is the ultimate sport touring engine, while the T124 Harley replacement engine is just what you need for a hot rod bagger. The T111 Harley replacement engine has a 4.125 bore and a 4.125 stroke for a true square engine making it the smoothest Harley replacement engine available. The T124LC Harley replacement engine is a slightly lower compression version of the T124 with S&S Cycle 640 Easy Start gear drive cams that is ideally suited for heavier bikes and trikes, plus it’s more tolerant of variations in fuel quality.

These Haley replacement engines have the same performance as S&S Cycle T-Series Harley replacement engines for 1999-’06 Harley-Davidson® big twins, but are built with the new S&S Cycle Super Stock T2 Crankcases for 2007-later Harley bikes (except Twin-Cooled™ models). These Harley replacement engines require an S&S Cycle oil line kit for installation. Not available for Dyna® models or Late model Softail®

Call DC V-Twin today to learn more about making your bike the best it can be with one of the new S&S Cycle Harley replacement engines. Whether you go with the T111 for cruising cross country and around town or you choose the T124 for ripping up the asphalt with maximum power S&S Cycle and DC V-Twin has you covered.
