I should say RE-Drilled holes in handlebars from M6 to M10x1.5. Handlebars are a great tie down location. I just had a problem with having my grips/throttle tugged at for hours at a time, so I decided to put M10 eyebolts there while in transit.
I chose M10x1.5 because of strength, the eyebolt will NOT be in the ideal load orientation (in regard to tie-down of the truck), but still underloaded (unless I put the truck in a ditch). Handlebars are aluminum and easy to drill from M6 to M10, then hand tap.
The M10 button head bolts I got from McMaster were a little shorter, so I had to create a shoulder, (with my hobby lathe), I have black end caps on order from McMaster to make this a more professional looking job.
