Right fuss after outrageous speed: it's criminal (9)
I believe the answer is:
desperado
'criminal' is the definition.
(desperado is a kind of criminal)
'right fuss after outrageous speed' is the wordplay.
'right' becomes 'r' (common abbreviation).
'fuss' becomes 'ado' ('ado' can be a synonym of 'fuss'**).
'after' is a charade indicator (letters next to each other).
'outrageous' indicates an anagram (I've seen this in other clues).
'speed' with letters rearranged gives 'despe'.
'r'+'ado'='rado'
'rado' after 'despe' is 'DESPERADO'.
'it's' acts as a link.
(Other definitions for desperado that I've seen before include "Wild ruffian" , "Bold outlaw on the American frontier" , "Gangster" , "Bandit, outlaw" , "Road speed (anag.)" .)
