I rode a V50 one weekend before I bought my Mille. It didn't have much low RPM punch, but once I got going the engine perked up considerably. In comparison, both my Mille & Eldorado have a "stump pulling" torque sensation practically right from idle. On the other hand, it was really fun on twisty back roads, but on the highway, not so much. It could keep up with traffic at 60-65 mph, but it wasn't happy and it didn't seem that it really had that much more potential speed in reserve. People have & still do tour on V50s, but it wouldn't be one of my bikes of choice for that kind of riding.
Your "new" V50 does look like it will clean up really nice without too much effort or $$$!
