:welcome:, you have found the best site for anything to do with spyders. You already have some great information above, I would like to off my 2 cents for what it worth.
As you are properly aware most owner forums we will tend to be bias to our choice of vehicle. I'm still new to the Spyder (honeymoon phase), purchased mine in late May 2012 and only have just under 5,000 miles, if it wasn't for work and family commitments I would have a lot more miles.
I've been riding for over 35 years and have had many different bikes in that time, my last was a Goldwing which I traded for the current RT Limited that I ride. I have posted before that I was getting board with riding and my bike sat most of last year in the garage. I've ridden all over Europe and most of the East Coast here in the USA and was getting tainted with been there done that. The Goldwing although a great touring bike was becoming a pain in the rear after a long days ride, two up with trailer in tow, its a heavy bike to move around when you're tired and trust me I'm not a small guy. My wife was riding less and less with me as well, she has hip issues (just had a first hip replaced last week) and was finding it extremely hard to get on and off the wing. Don't get me wrong the wing is a great bike for touring, proven, reliable comfortable but in my very humble opinion just a bit boring. When I was looking to replace my wing I looked at all sorts of bikes, the new Goldwing(2012), BMW K series and the Visions to name a few.
I started looking at this forum when my interest peeked in the Spyder, I posted here with question and thoughts on trading my Goldwing, to cut a very long story short its the best move I've made in years. This bike is so different and fun, the fun factor is hard to describe because its so different. I've had many bikes of all different types from scooters, dirt bikes, racers, cruisers etc but this as been the best. I know that this is my current bike and by definition your current bike is normally your favorite but its hard to explain this is my ultimate bike. Its so different, comfortable easy to ride legal fun you can have on three/two wheels. My wife prefers the spyder as well, more relaxing easer to get on and off. Once she as both hips replaced we will be out riding next year all over the place. Its comfortable stock, but just like Goldwings you can add better seats, suspension and goodies to meet your needs and budget.
Like all things in life, because we are all different there are things that I would like to see changed/added but these are few and far between as it just works. It would be great to have a 1800cc inline 6 engine, but thats not going to happen. The current engine is more than capable, its a race proven Rotax engine that been used in Aprilla motorcycles for years and as been proven for longevity and reliability. The Spyder is a relatively new design heavily reliant on electronics with all the safety features and sensors it as it normally those that fail before the engine.
You will find post here of issues with limp modes and issues ranging from minor to major, but this will be the same with any forum be it Goldwing, BMW, Ford, GMC etc. By nature people will post when they have issue more then the will when they don't. Would be a boring thread if all everyone posted "went for a ride and nothing happened". There are thousands of owners here who have not had any issues, many have issue with I wish it had this, or I wish it didn't do this, its too hot too cold so on and so fourth but not that many that have had compete failures.
There are a many here that will go on rides of 10,000 miles or more :bowdown:, I wish I had the time to do the same. My bucket list is to do a tour of the USA over a month or so, once my last child is either sold or off to collage (which ever I can swing first) I will take a month off work and tour (dreaming here). But I would trust my Spyder on any long run, I have faith it will get me there and back.
Cost are relative with any big bike, I'm paying in line with what I paid for my Goldwing services (Goldwing tax is about equal to Spyder Tax), I think BMW still holds the record as the most costly to maintain. I would recommend finding a good dealer in your area, get the BEST extended warranty and if your dealer offers it get a service contract. It will take a good 400-500 mile run to get uses to how it handles, I once saw a post over in the GL1800 rider forum where a goldwing rider traded to a Spyder and hated it and traded back within 3 days. Then there are those like me that traded and love it. I ride the Spyder out of choice not because I need three wheels.
Good luck with your choice, take a long demo ride, go to a few dealers find a local spyder rider and get as much info as you can.
