My question is---who wants to be a trailer biker?? Just ride them.
John, I doubt I would ever be a "trailer biker." As of now, I don't own a scooter, and if/when I get one, I assure I'm getting it to RIDE IT. That said, I also don't think a 150cc scoot is suitable for long-distance riding. You aren't going to get on an Interstate with one -- at least I'm not -- for more than a couple miles. It just wouldn't have the horsepower to be feasible for cross-country touring.
I live in a fairly rural area, and my interest in a scooter would be to use it locally, both for errands and just to enjoy riding the mountain roads/back roads in my local area. There would be tons of places to ride around here, as most of our local roads are back roads without tons of traffic. A scooter would be very practical, efficient transportation to say, go to the local grocery store or to my gym. To drive from my house to one of the local farms I hunt when checking trail cameras. I have no expecting of "off-roading" in a scoot, but one that could at least travel along a dirt farm lane would be nice.
So, when I talk about trailering the machine, I am merely acknowledging that I doubt I would get on a 150cc scoot and head to other states. Oh, I am sure there are those who have ridden cross country on one and documented it on YouTube. But I will not be among them. If that were my goal, I'd be considering a 400cc or higher machine. However, let's say I was going camping for a week at the beach. I would definitely be interested in trailering the scoot along. I wouldn't drive it from Pennsylvania to Ocean City, Md., for example. But if I put it in the back of the truck, I'll bet it would be a lot of fun to drive between a beach house and the beach, local restaurants, etc.
But hey, this is just me. Everyone ought to buy what they want, and use it the way they want. I have three cars/SUVs to use as a practical transportation. My interest in getting a scooter is really just to have FUN.
