"I don't see the market. Small displacement ruins the experience. They would have to lighten the vehicle considerably and make it extrememly nimble. They need to focus on making ours more nimble!! C'Mon fellas. I just don't see it. But we'll see. It would basically be a three-wheeled "scooter", not a Spyder worthy of its lineage. In fact they shouldn't even call it a Spyder. Call it something else and attract the demographic that would be interested in something like that."
Be careful, you are sounding a lot like a Harley snob.
The demographic for Spyder owners (at least according to the thread posted here a while back) is a good % of riders who are 55+ and there may also be a fair number who were "scooter" riders. I traded a Piaggio MP3 in for the Spyder and i can tell you that the MP3 out-performs the Spyder hands-down in every category except speed/power. I bought the Spyder because I wanted to be able to take longer trips. Oh, and the MP3 is also more reliable and over on the Vespa site you rarely see threads complaining about parts, service or having to wait weeks or even months to get your bike back.
I can't see any problem with BPR coming out with a few different size Spyders at different price points.
