TWIN CAM HARLEY REPLACEMENT ENGINE 143"

If Bigger is Better, the S&S Cycle 143 is the Best…
The BIGGEST, BADDEST, BOLT-IN for a Stock Frame.

All joking about size aside, it does matter. The S&S 143 Long Block engine for 2008-later Harley Davison touring models is the largest S&S engine that will fit in a stock Harley Davidson chassis. It’s big, 143 cubic inches. Nuff said.

At double the HP of a stock motor the power of the 143 requires technical expertise for the installation and tuning along with an experienced rider. This is an ultra performance/race engine.  Longevity, engine noise, vibration and throttle sensitivity have all been compromised to reach this level of performance while fitting in a stock chassis and as such is not suitable for every situation. It is the purchaser’s responsibility to consider the suitability for their application. Engine noise and damage from abuse is not covered under warranty.
