ST4 916 ST3 1000 ST4S 996 ST2 944 748 800 996 998 Hypermotard 796 1100 Material: This motorcycle voltage regulator is made of a special material that combines wear resistance and reliability, ensuring a stable power output during daily use. Function: The voltage regulator rectifier maintains stable voltage, minimizes noise interference, accelerates throttle response, and shortens engine start-up time. Purpose: It helps dissipate excess voltage, improves charging efficiency, prevents battery overcharging, provides high reliability, and allows for quick rectifier replacement. The function of the motorcycle rectifier is to convert the vehicle's alternating current into direct current for use by electrical devices. The current required by the motorcycle's electrical device is generated by the magnet. If it does not go through the rectifier, the voltage will fluctuate with the engine speed and is proportional to the engine speed. The electrical appliance cannot withstand this current and can easily be damaged. Easy to use: Installation can be successful with simple operation. Repairs can be completed in a short time and require little or no mechanical expertise.
