Hi all, What size allen wrench is used to remove allen bolt in bottom of fork legs?

Thanks,

I think its a 7mm but pick up a set of metric Allen wrenches.. You'll need them.

my 1990 used a 8mm...

you might be right about that 8MM.. I have the full set, so I just pulled out what fit. :biglaugh:

Pretty sure that 8 mm is correct.

I went to Lowes and bought another long set for under $30 for the 3/8" drive. I have like 3 sets, always looking for one that I didn't put away...

My 95 used a 10mm which is basically the same as 3/8"

It varies depending on the year. 8mm or 10mm. I use a apex socket bit.

OK, thanks everyone for the replies.

Now a new question, what length of 3/8 drive allen wrenches do I need to reach the fork tube bolts with an impact wrench. Shorter is better with an impact so I don't want to buy longer length than I need.

Regards,
Wayne

I don't remember. Can't you just use a pencil or small screw driver and put it up in there and measure it? I cut down an allen key.

I bought the longer one at Lowes. the single key was like $8, the set was under $30.. I think the longer ones are around 6", but you need maybe 4".

I was wrong. They bolts in the bottom of the forks are 10mm, and don't use one of the allen keys that is the swivel head they will strip out the allen head easy if you are using a air impact gun... I noticed this doing the 2nd set of forks this summer. My shorter key still fit fine going in the bottom of the fork.
