Inside, of course. Back in 2006 I rebuilt the Ducati engine here, so this office desk should suit.
According to the manual, I need to measure all of the plain bearing surfaces to see what size bearing I need to buy. Somehow I need to beg or borrow a vernier caliper that measures in mm, down to 3 decimal places. Not a common tool from the local hardware store!
I also fabricated some steering stops from some swingarm sliders.
