I'd really consider one, if they would consider putting one on a 1500 Valkyrie. According to the website, only 1800 'Wing right now.
I've been following them for a couple of years. A Valk 1500 was one of their developmental bikes. They offered ot for sale about the time I began following them.
As to Old Too Soon & $$$$, I've read in this forum of 1800 GW variants selling new in the range of +/- 11K, add 12K for kit, 2K installation, and you have a 25K reverse leaning trike as opposed to +/- 38K for a new California Sidecar/Roadsmith/Motortrike etc. trike. Plus, you still have the original bike by only reinstalling the front forks.
I inquired about a year ago and was told "no immediate plans" for a 1500 Valk. Personally, I think they can be persuaded after they get settled in with a network of authorized installers.
I now ride a trike and many trike people say a Valk trike is the best and I completely agree.
