This is a brand new starter relay solenoid switch, built as a direct replacement for the original unit fitted to Yamaha FZR 600 to FZR 1000 and Virago 250 machines. The starter relay is the heavy-duty switch that sits between the battery and the starter motor. When you press the start button, a small current energises the relay coil, which closes a set of high-current contacts and allows the full battery current to reach the starter. Because it handles that entire load, the relay is one of the most heavily stressed electrical parts on the bike, and the internal contacts eventually pit, corrode or weld from repeated arcing.
The quality of this unit exceeds the OEM equipment it replaces, and every product shipped is tested before it leaves us. It carries the same body dimensions, the same two-wire trigger lead and the same twin heavy terminal arrangement as the factory part, so it drops straight into the original mounting position and reconnects to the existing loom and battery cables without cutting, splicing or modification. If you are unsure whether this is the correct unit for your machine, compare the terminal layout and overall size against your original relay, or check the OEM part number stamped on the old unit against the cross reference table below.

Frequently Asked Questions
Do I need to modify anything to fit this relay?
No. This is a direct replacement for the original unit. It uses the same two-wire trigger lead, the same two heavy terminals and the same two plugs as the factory relay, so it fits the original mounting point and reconnects to the existing wiring without cutting or splicing.
What is included?
One brand new starter relay solenoid switch, tested before dispatch. Reuse your existing battery cables, starter cable and mounting rubber.
How do I know my old starter relay has failed?
The classic symptoms are a single loud click with no engine rotation, repeated rapid clicking, or a start button that works intermittently and then not at all - typically worse when the engine is hot. If the battery is fully charged and the headlights stay bright when you press the button, the fault is usually in the relay contacts rather than the battery. A relay that is silent when triggered but shows battery voltage at its trigger wire has an open coil.
How do I confirm this is the right relay for my machine?
Check the OEM number moulded or printed on your original relay against the cross reference table above, and compare the physical size - this unit measures 53 mm high, 52 mm long and 48 mm wide. Yamaha used several relay bodies across this period, so the OEM number is the most reliable check.
