Great looking fun and creativity. These customs likely can roar, burn rubber, and run like a rocket, but suspect they'd be a "WTFOT adventurer " when stuffing one into a turn. Noticed blue one not plated - TIT so maybe some "exemption" to vehicle road rules for when transporting show bikes to and from a viewing or show. Builder in Pattaya never could get his custom a book or plated, even with numerous brown envelopes passed around, but could drive it to/from custom show.
Acquaintance "Nicky," owner of Nicky's Handlebar (bar, restaurant, hotel) on Phuket Island (Patong Beach) has the black custom trike in the photo below at the entrance to his bar/restaurant/hotel. It doesn't get much road time. He said it's more for "show" than "go." :-)
