A brand new aftermarket two-position ignition key switch, supplied as a direct replacement for the original unit fitted to the Yamaha YFB 250 Timberwolf and YFM 200 Moto-4. It is plug-and-play and fits directly in place of the factory switch, so the standard harness connects straight up with no cutting, splicing or drilling. Our part number for this unit is RM05007.
The switch body stands 50 mm tall and is 35 mm long, and it carries four wires through two plugs. There are two positions, off and on. Two keys and the matching connector are supplied in the box, so the switch can be fitted and the machine started without sourcing anything else. Every unit is tested before it is shipped, and all of our item photographs show the actual part - if you are in any doubt, compare them against your original switch before ordering.

Frequently Asked Questions
Will it fit without modification?
Yes. It is a direct replacement for the original unit and is plug-and-play, using the same four-wire, two-plug arrangement as the factory switch. No cutting, splicing or drilling is required on the Timberwolf and Moto-4 models listed above.
What is supplied?
The ignition key switch, two keys and the matching connector.
How do I tell whether the old switch is at fault?
Look for a machine that is dead with the key turned on, power that drops out when the key or the harness is disturbed, a barrel that turns without a positive click between off and on, or corroded terminals in the switch plugs. A continuity check across the terminals in each position will show whether the switch is still making the circuit or has gone open.
Which OEM numbers does this cover?
Yamaha 2FH-82510-00-00, 2FH-82510-01-00, 2FH-82510-02-00, 2FH-82510-09-00, 1NU-82510-00-00 and 1NU-82510-01-00. Check the number on your original unit against this list before ordering.
