I was in my local Triumph dealer yesterday. They had one '11 Speedy on the floor that had just been purchased, oddly enough by a guy I had pegged as a harley rider but I guess that's what I get for going by appearance only. Anyway so I sat on his new bike to test the seat and I wasn't too impressed. It supposedly sits an inch lower but I couldn't tell much difference and didn't think it was all that comfortable, but then I only sat in it very briefly. I asked the sales guys if it would fit an older model, but they didn't know for sure. Said they didn't know why it wouldn't fit but they hadn't tried it yet. Sorry, don't have any more info than that.
