I assume they can be installed on Harleys.

 

I'd go Trike before training wheels.

 

I have a voyager unit in my garage that is set to go on my softail
have ridden it with the unit attached and it is not bad at all
comes off very easy and goes back on just as easy takes about 3/4 hours to set it up

 

It must have been a older Voyager kit I saw on this Wing.
It was made outta 2-1/2" box steel, in a sorta "U" shape, with looked like trailer spoke wheels with fenders.
It was a manfactured kit, not a home made.
I had looked on Ebay for one, there were a lot of sale, (thinking I make a rat bike into a 4 wheel bike for winter riding), but never got @ to doing it.
The voyager kits I saw on this tread may be the "updated version of this kit.
He doesn't want a trike or trike kit??????
(That's my next new purchase, I test rode one, LIKE it)!
