Spooks Wheels

[JHyde]

I am curious as to what sort of motorbikes spooks use. They're used twice on the show that I can think of: once in 1.2, with the bike's rider taking out Kevin McNally's character and once fictionally

Spoiler: show

in 4.10, as Zaf explains how Diana might have been killed.

I don't know how common bikes are in London though, so I'm not sure what the balance would be in blending in/upmarket motorbikes. You wouldn't want anything too lightweight though, not in a windy, wet city.

On a related subject: when Penry Jones and Peter Firth were on Top Gear, was there any discussion about what cars might be used by the Security Services?
