What Bike?

I would recommend a 250 over a 150 because if you ever have to ride on the highway a 150 will not be able keep up with the traffic and will put your life in danger. Here in PA they offer free motorcycle safety course and provide motorcycles for the course, They are 250's and most of them are Honda Shadows. These are good training cycles and are not very expensive. However, if this will be your first bike buy used and pay cash, get the experience of riding before moving up to bigger and more expensive bikes. I have had friends who bought big bikes like Goldwings and rode only a few times then selling them at a loss because they weren't ready for a big bike. Nothing wrong with starting small and working up to bigger later on. In fact the smaller bike will normally sell quicker when you are ready to move up, then use the money for your next bike.
