So, I tested a Spyder yesterday...my thoughts;
Looks fab, IMHO. The Dealer had a Pearl White model in stock. Sexier than my wife's best friend...but $21,000....OW!
Driving / Riding impressions...good points, comfy as heck. No need to put feet down when stopped. Bike accelerates OK (not a VTR, but not meant to be) and the semi auto shifter is VERY trick. Brake is good (just one footbrake).
Bad points; OMG...aproaching a turn...pucker up!! Flippin thing dances all over the road...like a whippet on crack...manic! Bizzare handling. Twitchy and nervous, and very unpredictable in the turn. Super sensitive to bar input...I guess best to just relax and enjoy...(heard that one before)..

Overall, not my bag, but I respect what they have done with this concept. Kudos to BRP. But I'll stick with my VTR, thanks...

 

I've heard basically the same thing you just said from everyone that I know who has test riden one. They sound kind of scary! I picture trying to lean into a turn and being stumped. I bet it's also strange (like on a quad) to stop and not want to put your feet down. When the first quads came out they didn't have a heel protector so if you tried to put your feet down during a stop, the rear wheel would grab your heel hard!

 

A guy I work with has one. They look kinda cool and kinda fast. That's about as far as it goes for me. Not really my cup of tea.
