An S&S V124 engine typically produces around 128 horsepower right out of the box. This powerful output is a hallmark of S&S Cycle's performance-oriented V-Twin engines, which are engineered to deliver substantial power and torque.
Understanding the S&S V124's Performance
The 128 horsepower figure represents the baseline performance for a new S&S V124 engine. These engines are designed for enthusiasts seeking a significant upgrade in power and performance for their motorcycles, especially Harley-Davidson models. Beyond horsepower, the S&S V124 is also known for its robust torque, often exceeding 130 foot-pounds, which translates to strong acceleration and pulling power across the RPM range. For instance, reputable sources indicate the S&S 124ci engine can achieve approximately 128 horsepower and 139 foot-pounds of torque.
Key Specifications of the S&S V124 Engine
To provide a clearer picture of its capabilities, here's a summary of common specifications for the S&S V124:
| Specification | Value |
|---|---|
| Horsepower (Out-of-Box) | 128 hp |
| Torque | Approximately 139 ft-lbs |
| Displacement | 124 cubic inches (2,032 cc) |
| Engine Type | V-Twin |
Factors Influencing Actual Horsepower Output
While 128 horsepower is the general specification for an S&S V124, the actual power delivered to the wheel can vary. Several key factors contribute to these differences:
- Engine Tuning: Proper calibration of the engine's fuel delivery and ignition timing (often through an aftermarket tuner) is critical for optimizing performance. A well-tuned engine can maximize its power potential.
- Exhaust System: The design and back pressure of the exhaust system play a significant role. High-performance aftermarket exhaust pipes are often paired with these engines to improve exhaust flow and enhance horsepower.
- Air Cleaner: An efficient, high-flow air cleaner allows the engine to ingest more air, which is essential for combustion and power production.
- Dyno Conditions: Horsepower figures are measured on a dynamometer, and results can fluctuate based on ambient temperature, humidity, atmospheric pressure, and even the specific dyno used.
- Maintenance and Wear: Over time, engine wear and lack of maintenance can lead to a decrease in peak performance.
By optimizing these elements, motorcycle owners can ensure their S&S V124 engine performs at its peak, providing an exhilarating riding experience.
