I could be wrong, but I'm sure I remember Top Gear testing bikes, albeit a very very long time ago. Probably in the days of William Woollard (ask yer mam) Noel Edmonds and Tiff Needell.
Seem to remember Steve berry testing a couple of bikes when he did a stint on it.
Clarkson gets pissed off when he spills his Pimms on a Sunday afternoon, whilst sat in the garden of his Chipping Norton home, when something with loud pipes goes past.
