Leave Stark injured in small racing vehicles? (2-5)
I believe the answer is:
go-karts
'small racing vehicles?' is the definition.
(I've seen this in another clue)
'leave stark injured in' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'injured' is an anagram indicator.
'in' indicates putting letters inside.
'stark' is an anagram of 'karts'.
'go' going within 'karts' is 'GO-KARTS'.
(Other definitions for go-karts that I've seen before include "Small motor vehicles" , "Light vehicles for racing" .)
