So, for 6 x 1, I need 5 mm drill bit? As 5T said? Good.
Before I drill, just been thinking. The obvious place to put the grease nipple is on the weld, in the middle, under the swing-arm.

That's the underside.
But as I said, been thinking and that's always dangerous.
When the bike is back together, the chain and the centre-stand and the exhausts are going to get in the way of applying a grease gun. Is
under the best place to put the nipple, or would it be more accessible in a similar position but
on top of the swing-arm?
