Similar to the 650 posts [and I think I posted on this on the 400 section, too] I crudely bent a 3/16" x 2" iron bar from Lowe's, drilled holes in between the plastic grids of the support for the footboards and used 1/4" bolts secured by fender washers to lock this bar onto the foot board - at first I just attached 3/8" bolts, covered by a 3-1/2" length of galvanized 1/2" pipe - very crude

, but also effective.. - VOILA! :thumbup: and my 400 has fully functional if not completely elegant highway pegs! The plastic footboard material doesn't offer the most secure purchase, so I would not stand on the pegs, but they hold the feet very well. :wink: Then I bought some $10 basic foot pegs from CycleGear and they definitely look better. $10 pegs is ok, but I just could not spring for some of the far more beautiful but spendy Kuryakins or other high end brands.
I think I posted a pic or too, but that was before I found the inexpensive Cycle Gear pegs
There is probably a frame member somewhere very deep under the plastic which would be a far more secure attachment, but you'd have to drill visible parts of the tupperware and the pegs would then be at the end of a pretty long lever arm, which might lead to flexing and tupperware damage.
** sighhhh ** It sure would be nice if it were possible to attach real crash bars to the front [and maybe the rear] of the 400 to facilitate mounting a whole lot of accessory lights, highway pegs and other REALLY necessary after market products to trick out the bikes, wouldn't it? :roll:
Just some of my thoughts,
