I have owned a second-hand TU for about a year. It's a fine, simple bike, and very forgiving of new rider errors such as releasing the clutch too quickly. With classic styling plus modern electronics and fuel injection, it's a head-turner that's very reliable. My daughter is learning to ride on the TU. When she's not using the TU, I'll use it to commute every now and then. Air cooled -- no problem. Although a bit on the small side, the TU would be a superb daily commuter on roads up to about 60 MPH.
