S&S Cycle Crank Position Sensor 55-1051 for Enhanced Engine Performance

The S&S Cycle Crank Position Sensor part number 55-1051 is a critical component designed to optimize engine performance and reliability. This sensor works in conjunction with the engine's Electronic Control Unit (ECU) by providing precise crankshaft position data, which is essential for accurate ignition timing and fuel delivery. Its integration ensures smoother engine operation, improved power output, and better fuel efficiency, making it a valuable upgrade for performance-oriented motorcycles. The sensor is compatible with models that utilize crankshaft position sensors and is made in the USA, reflecting high manufacturing standards and quality assurance.
The system incorporates multiple sensors, including a cam position sensor if present, MAP sensor, cylinder head temperature sensor, and an exclusive knock sensor that detects engine detonation or knocking during operation. The knock sensor allows the ECU to automatically adjust ignition timing on the fly, eliminating knocking and maximizing engine efficiency. The inclusion of the Knock Sensor and its automatic adjustments enhances engine longevity by preventing damage caused by pre-ignition or knocking. This sensor is particularly suitable for models equipped with S&S Variable Fuel Injection Systems, offering seamless integration and enhanced engine tuning.
Please note that the S&S IST ignition modules manufactured after October 1, 2003, already include software for the Guardian Diagnostic System, supporting all applications except certain 2004-2005 models. An optional high-output single-fire coil, which features two separate coils in one package with a 3-ohm impedance per coil, is sold separately and designed for use with this system. Installation of this sensor requires an installation kit, which must be purchased separately. It is not recommended for kick-start applications unless a cam position sensor is used, as engines with crankshaft sensors can be difficult to kick-start. Overall, the S&S Cycle Crank Position Sensor 55-1051 offers a reliable, high-quality solution for enhancing your motorcycle's performance and diagnostic capabilities, making it an excellent choice for enthusiasts seeking precision and durability.
