Perhaps we should also consider this:

I can't see where Can Am is in the forefront of reverse trikes, particulary when this one (Ok it's a scooter) has been on the market for several years. Piaggio is a very large builder of scooters and motorcycles, and the MP3 line, simply by it's ability to lean, is way ahead of the Spyder. The engineering is done, they already have access to some engines with much more power, and I'm not so sure they don't have nearly as many dealers in the US as Can Am. When Piaggio builds something with about 1000cc's and a good touring ability, I will be there (but not a first year model again!!). Something to think about!
