Starter Relay Solenoid for KTM and Suzuki

KTM 950 and 990 Adventure, 690 Duke and Supermoto - Suzuki Marauder, Katana, Burgman and Boulevard - 1994-2026

This is a brand new starter relay solenoid switch, supplied as a direct replacement for the original unit fitted to a broad range of KTM and Suzuki machines. RMSTATOR states that the quality of this relay exceeds the OEM equipment, and that all products shipped are tested before they leave the factory. Part number RMS090-102093 covers KTM 950 and 990 Adventure, 690 Duke and 690 Supermoto models, along with the Suzuki Marauder, Katana, Burgman and Boulevard, across a 1994 to 2026 coverage span.

The starter relay solenoid is the heavy duty switch that sits between the battery and the starter motor. When you press the starter button, a small current energises the coil inside the relay, which in turn closes a set of high current contacts and allows the full battery current through to the starter. Because it handles that current on every single start, the contacts and the coil are among the more common electrical wear items on a motorcycle or scooter. This unit measures 50 mm in height, 40 mm in length and 34 mm in width, and carries four terminals and one plug, matching the original layout so that the existing loom and mounting can be re-used without modification. RMSTATOR notes that all item pictures are accurate, so if you are in any doubt you should compare the unit shown against your original part before ordering.

Frequently Asked Questions

Will this relay fit without modification?

Yes. It is a direct replacement for the original unit, with the same four terminals and single plug, so the existing loom and mounting are re-used as they are. Before ordering, compare the part number stamped on your old relay against the cross reference table above.

What is included?

The starter relay solenoid switch itself. RMSTATOR does not list any additional hardware with this part number, so re-use the original mounting rubber, cables and fasteners from the unit you are replacing.

How can I tell the old starter relay has failed?

With a battery that is known to be good and fully charged, a failed relay typically gives a single loud click, repeated clicking, or no sound at all when the starter button is pressed, and the starter motor does not turn. Burnt, discoloured or corroded terminals on the relay are another common sign.

What safety precautions apply when fitting it?

RMSTATOR warns that there is a risk of electric shock. Disconnect the battery before servicing, and ensure the unit is properly installed by a qualified technician to avoid malfunction.
