S&S V111 engines are perfect for applications that require great horsepower and torque, but not at the expense of dependability and engine life. They are similar to the V124 engines, but the shorter stroke results in lower piston speed for longer engine life, and less vibration. The lower compression ratio makes fuel requirements less critical, and the automatic electric compression releases make starting even easier.
