Spark plug wrench?

Bumping an old thread, but here’s some useful into.

Bought a 2012 KTM250EXC-F recently, which needs a thin walled socket to access the spark plug. I asked a KTM mechanic what he uses, and he showed me the socket that he has.

It’s a Bikeservice BS9133 Extra Thin Walled Spark Plug Socket. I bought it from a car accessories chain here in Australia called Supercheap Auto. Cost me $14.99. It’s a 3/8” drive, so I bought a 1/4” to 3/8” adaptor from a hardware shop and will use it with a small 1/4” ratchet.

After not even starting my 2006 Gas Gas FSE450 since 2008 I’m going to give up and sell it. Great bike… I bought it new and didn’t really use it. I’ve gone to a 250cc four stroke, hence the KTM.

I’ve got no idea if and where this socket is available in other countries. The Bikeservice web site is www.bikeservice.com.tw

This is what works. I bought two of them - one for the toolbox and one for my bumbag.

I bought some 1/4” extension bars and a 1/4” to 3/8” adaptor at the same time.

Yep, that’s thin walled.

Fits in the KTM perfectly.

The rubber collar inside the socket is just the right size - enough to grip the spark plug, but you don’t have to wrestle with it afterward to get the plug out of the socket.

I’ll be using a 1/4” ratchet and 1/4” to 3/8” adaptor with it.

For anyone in Australia, this is what you’ll be looking for in Supercheap Auto. It’s only a small section, so ask one of the staff if you can’t find it. In this photo the sockets are at the top right of the photo. Once you’ve got a socket then stop off at a hardware or tool shop and get a 1/4” to 3/8” adaptor or 1/2” to 3/8” adaptor if you don’t use a 3/8” ratchet (ie I don’t).
