250-500cc Can someone tell me what this is?

Went to load bike and noticed this hanging down. Can someone tell me what it is and where I can find another one? (the broken ceramic piece that looks like the butt of a cigarette, with wire all pulled out)

that according to your picture and description looks like an old school ballast resistor

Thanks 2premo. Do you know if I can replace with any type of resistor? or? I have never been good with electronics. I took off the tank and the other half is still tucked under a zip tie along with the rest of wiring running along frame.

not sure it came with the bike
what model CC and year is yours?

2009 wr300. I did see anything like it on the wiring diagram, but admittedly I electrical issues are not my strong suit

that's not a thermostat is it? Not sure if the newer ones have any but my bike came with one standard, bolted from a wire like that into the cylinder head on a small clip

YOUR THINKIN OF A TEMP PROBE FOR A FAN AREN'T YOU? THE THERMOSTAT WOULD BE IN A COOLANT HOSE

It is electrical protection for the speedometer instrument.

Thanks! I am going to cut it off an cap it. I don't have the speedo anymore. Cheers everyone. Great help!!
