Starter Relay Solenoid for Honda and Kawasaki
Honda CB, GL, VF and VFR 650 / 750 / 1100 1979-1991 · Kawasaki Ninja 250 / 500 / ZX-6 and VN 800 / 1500 1990-2012
This is a brand new aftermarket starter relay solenoid switch, supplied under RMSTATOR part number RMS090-104066. It is a direct replacement for the original starter solenoid fitted to a wide range of Honda CB, GL, VF and VFR road bikes built between 1979 and 1991, and to Kawasaki Ninja 250, Ninja 500, ZX-6, VN 800 and VN 1500 models built between 1990 and 2012. RMSTATOR builds this unit to exceed the original equipment specification, and every unit is tested before it is shipped.
The starter relay solenoid 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 coil inside the solenoid, which closes a large internal contact and lets the full battery current reach the starter. Because that contact carries the entire starting load, it is one of the first components to burn or pit as a machine ages. Once the contact surface is damaged the starter will crank slowly, crank intermittently, or not crank at all. Replacing the solenoid is far quicker and cheaper than stripping the starter motor itself.

Frequently Asked Questions
Does this solenoid fit without modification?
Yes. On the applications listed above it is a direct replacement for the original unit, using the same terminal layout and the same mounting position, so no cutting, drilling or rewiring is required. Check the OEM number stamped on your original solenoid against the cross reference table before ordering.
What is supplied in the box?
The starter relay solenoid itself. RMSTATOR does not list any additional cables, brackets or mounting rubbers with this part, so keep the mounting rubber and the battery lead from your original unit and transfer them across.
How do I tell whether my starter solenoid has failed?
The usual signs are a single loud click with no crank, a starter that works only intermittently or only when the machine is cold, or nothing at all when you press the button while the lights and horn still work normally. Because the solenoid carries the full starting current, its internal contact wears out long before the rest of the starting circuit does.
What does the 150A 30S rating mean?
It is the current the internal contact is designed to carry - 150 amps for a 30 second duty period. Starting an engine draws a very large current for a very short time, and this rating is what allows the unit to handle repeated starts without the contact overheating.
