The spyder is NOT a roadster. From Wikipedia, the free encyclopedia, A roadster, also known as a spyder or spider, is a two-seat car, traditionally without a roof, side or rear windows....

BRP made this bike,trike,quad,roadster to attract NON motorcyle enthusiasts,.. but naturally, snowmobilers, atv'rs, and bikers have decided to hop on this bike,trike,quad,roadster too.
People ask me is it like a snowmobile?? Nope I tell them, it's like an atv with lots of balls. I personally can't wait for another manufacturer to hop on the r-tike bandwagon and start building these too. The only other options out are Vertika, and custom r-trike builders. Iv'e ridden with a Vertika r-trike and it's the best r-trike out IMO.
