I am trying to find out what the best option is for buying a turn around vehicle for fishing on my own.

I see a lot of people buying/selling Honda Trail 90's and 110's...how fast will one of those go with a 200 lb adult on it?

I think I need something that will do at least 55mph, and is somewhat light so I can manipulate it into my truck bed or trailer without someone else.

Any suggestions from anyone on makes/models of motorcycles, mopeds, or scooters that could possibly fit the bill? Or anyone come across a sweet method for hauling them on your truck or SUV?

The help is much appreciated.
