Tips for 'SUB 1K' singles??

Still looking for a bike for my wife to use in conjunction with the Campervan. If I spent a grand or less, I wanted a bike capable of 50mph over a reasonable distance and RELATIVE reliability. what would be my best bet?I like the Zigolo, Ive seen a few go around the grand mark, my knowledge of singles is pretty poor really. Id consider a two stroke twin perhaps?PICS to accompany any reply would be ACE.

Go with the Honda Innova you will not regret it.modern technology and great mileage per liter, a good top speed as well. Parts are easy to get if you need them.
