Jonesy is right about the stiffer ride. Had a Tri-Wing kit on my 05. I rode that bike for almost 5 years putting 30,000 miles on it before getting "T" boned by a cage.
Handling is OK but after having my current Hannigan I would never go back to a solid axle trike. Unless Tri-Wing has upgraded their kits you'll still be dealing with drum brakes. I converted the drum brakes to discs within a couple years just to get more even, better stopping brakes. It also made a world of difference for stopping.
Hannigan has a lower profile, longer and wide wheel base to enhance handling. B2Dad called it a Vette on 3 wheels. LOL
