I just ordered my RS HTS conversion kit for my 2010 Goldwing a couple weeks ago, should be in in a couple weeks. I was trying to keep the conversion under $15,000 and opted not to get the wind wings, but did order the adjustable suspension that uses the OEM suspension controls and ram, I also ordered the Performance Sway Bar. I'm anxious to get the conversion done so I can put the trike through it's paces, I'll report back my experience and opinion for what it's worth, I know I have a learning curve to go through.
The folks who installed my conversion used one of the Performance Sway Bars and after trying a kit with one said they were a huge handling and ride upgrade. Have it done when the conversion is done as it has to be done with body off...
