Yes, I've got the RS model.
Reason I've bought it? I can drive it without a motorcycle license in Europe but can still enjoy the feeling of open air riding.
Reason of it having 2 wheels in the front vs. 2 in the back (trike) = more safety, better braking (most traction while braking is in the front of the vehicle).
It handles very well, different than a motorcycle though as you move differently through corners, once your used to it it's natural. I guess you can compare it more to a Snowmobile or a Jet-ski handling wise.
It has quite a few safety features such as: Vehicle Stability System (VSS) that includes ABS, Traction Control and Stability Control.
The built in front trunk (11.6 Gal) is nice for the quick shopping tour or to just carry stuff with you without saddle-bags or a backpack.
It has RWD powered by a belt that leads to a 998cc V-Twin engine made by Rotax that produces 106 hp.

P.S.: I'm not trying to be a biker or whatever, i just enjoy open air rides, but don't feel like taking the time to make a special motorcycle license in the country where I live, so since the Spyder gives me that feeling without the need of a MC license and I like the look / design etc. it was a perfect fit.
