My worst bike. A 50cc Di Blasi fold-up bike to use as a "paddock bike" when my old company did the British Saloon Car Championships in the late 80s and early 90s with "LISTERINE".
Flat out at 25mph and was always a pain to start (nothing new there then). I sold it for £750 before coming to Spain.
I always wanted a Honda Monkey bike, but by then they were over priced. I saw one advertised the other week for nearly five grand!
