Attachment for motorcycle is raced all over the place (7)
I believe the answer is:
sidecar
'attachment' is the definition.
(vehicle attached to the side of another)
'is raced all over the place' is the wordplay.
'all over the place' indicates an anagram.
'is'+'raced'='israced'
'israced' with letters rearranged gives 'SIDECAR'.
'for motorcycle' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for sidecar that I've seen before include "that's suitable for a non-driver" , "Passenger carrier attached to a motorcycle" , "Motorcycle addition" , "Cocktail - cedar is (anag)" , "Attachment to motor cycle" .)
