Motorcycle attachment (7)

Ross

I believe the answer is:

sidecar

'motorcycle attachment' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for sidecar that I've seen before include "In which a passenger may be taken" , "One-wheeled compartment attached to a motorcycle" , "Attachment to motorcycle to accommodate passenger" , "that's suitable for a non-driver" , "Low-slung two-wheeler" .)

I've seen this clue in The Independent, the Evening Standard, the Universal, The Times, The Mirror and the Sydney Morning Herald.
