Description

If you want to create the baddest bike on the block, you will need a T143! The S&S T143 Long Block engine is the biggest S&S engine that can fit into a standard Harley-Davidson chassis. With double the horsepower of a standard motor, the T143 demands technical competence for installation and tune, as well as an experienced rider. This is a race/ultra-performance engine. Longevity, engine noise, vibration, and throttle sensitivity have all been sacrificed to achieve this degree of performance while fitting in a stock chassis, thus it is not ideal for many situations.
