Heck, If you're only thinking another couple of years of riding a used wing would be the way to go. The older ones can be picked up pretty reasonably.
I was thinking that if I was going to go three wheels again it would be a Tilting Motorworks but it seems they have bellied up. I was considering one of their kits for my CVO softail but it was more cost-effective to buy an HD trike and then sell it or trade it in when I was healed.
This is my third knee infection and every time it happens it puts me down for a good 2-3 months. Takes even longer to be able to do two up. It's really starting to piss me off. We are getting ready to start a good riding season and I'm on the sidelines. I already had to cancel one moto adventure. I have 3 dayer schedule for August. I'm hoping to be healed enough by then.
There are some other options.
The Yamaha Niken looks interesting but doesn't look very two-up friendly for the long haul.
The Vanderhall would be another option but it's more car-like but very low to the ground.
An old Morgan 3 would be cool. I saw one in Sturgis and went totally gaga over it.
The Slingshot is another one but they are due for a body change. Again car like.
Other options an old MG Midget or Triumph TR3. Just have to remember to always carry a multi-meter, extra wire and electrical tape.
Without motorcycle riding in my life I just feel lost.
