Fork stem bolt-What metric socket size?

[djsb]

Hi,
What metric socket must be used to remove the large fork stem bolt (26 in this diagram part number 90304-mcf-000)

I think it is around 31mm but if someone could confirm this for me I would be very grateful. I don't want to go out into the freezing UK weather (bike parked outside) just to check it myself.

I need this so I can grease the bearings on the steering stem. Thanks.

I don't know the size but why do you want to grease those bearings?

On my last three Honda road motorcycles, I never greased those bearings but I've also done my best to keep water away from that area when washing the bike and never use a power washer!

Those bearings could get 'sticky' or wear out and making turning to left/right sticky/jerky/squiggly. BMW is notorious for not putting enough grease on those bearings and when my bmw g650gs hit 30,000 miles, I had to remove the steering head and grease those bearings-it was very notchy to turn full left or full right.
