Win a motorbike (7)
I believe the answer is:
triumph
I believe this is a double definition.
'win' is the first definition.
(I know that win can be written as triumph)
'a motorbike' is the second definition.
(I've seen this before)
(Other definitions for triumph that I've seen before include "Great victory or achievement" , "Crow" , "Prove superior" , "Victory, win" , "Successful ending of a struggle or contest" .)
