I am in the process of getting my first trike. I was considering putting a Hannigan conversion kit on a Triumph Rocket III. I talked myself out of doing that and am now going the HD route.
I tried out a couple of trikes at a local store at noon today:
1. 2006 (21xxx miles) with Lehman kit. Trike ran, sounded, and looked good; but in second gear wobbled pretty bad.
2. 2013 (2500 miles) Tri Glide. Everything was sound and no wobble on this one.
Store also has a 2002 (16xxx miles) with MotorTrike kit.
I did not ride that one yet. It looks good and has been well maintained. If it checks out, I will be inclined to get that one based on cost. If not, I'll probably do the TG.
