This bike is probably the third or fourth P55B ("F1 Sports" in Engand, "TT" in Germany) out of 67 P55Bs built that I had, the others being demonstrators/press bikes.
After I sold the last press bike I wanted a P55B again, and the opportunity arose when Lydia's female owner rang me, claiming she was pregnant and had no further use for the bike.
I grabbed the opportunity, knowing this was one of the nicest P55Bs I had ever ridden, and bought the bike for myself.
The reason why I knew the bike well was that the Lady owner had had constant problems with the bike overheating- a problem we never found with it.
We really tried as hard as we could, but whenever I or my then mechanic Tobi rode it, "Lydia" was well-behaved and really nice.
As soon as we gave it back we could bet the owner would ring within 24 hours about the bike overheating.
No doubt this constant problem was a major factor in her decision to sell the bike.
