A motorcycle starter relay is an electrical control unit that acts as a switch in circuits to connect the battery and the starter motor. Relays can have AC or DC coils depending on the required control voltage, and this unit operates at 12 V. Key benefits - Protects circuits by isolating high current loads from the ignition switch and other control switches, improving reliability and control accuracy. - Enables reliable operation of multiple motorcycle systems by switching power to start, lighting, ignition, fuel pumps, and other components as needed. - Simple to install, providing an easy upgrade to improve starting performance and overall electrical stability. Compatible model and applications - Fits Ducati M400 M 400 2002 with part numbers 27010-1075 and 27010-1314. - Ideal for use as a starter relay, ensuring stable operation of the bike’s electrical systems during starting and routine use. Specifications and materials - Weight: 120 g - Easy to install - Material: metal, plastic, aluminium - Voltage: 12 V - Package: 1 pc starter relay Usage scenarios - Replacing a worn or failing starter relay on a Ducati M400 2002 to restore reliable engine startup. - Installing to manage multiple systems (start, lights, ignition, fuel pump) for improved switching reliability and circuit protection. - Upgrading older motorcycles to ensure stable operation of high-current components through a dedicated relay.
