It’s for the spark plug socket.

The sump are torx bolts, but an allen key will work.

I thought that Allen key was for the front axle.

Not quite...front axle hex a way bigger...I got that one.

I think Triumph put the keys in the took kit as a joke to bewilder, confound and confuse Triumph riders.

Pretty useless tool kit. But the case works good for keeping my registration and insurance card in it.

Front axel is 19mm, just bought one :/. Amazing the tool kit doesn’t include one.
