Nick Sanders has a good claim on being the fastest man in the world on a motorbike
He has ridden round the world 8 times, twice on a pushbike and six times on a motorbike.
Somebody stole his round the world on a motorbike record in 2003 or 2004 and Guiness Book of Records then closed the record out of concern for public safety
Nick went back round the planet anyway (19,650) in just over 19 days.
