'went over 100' is the wordplay.
'went' becomes 'biker' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'over' is an insertion indicator.
'b00' becomes 'c' ('C' can be a synonym of 'b00').
'biker' going around 'c' is 'BICKER'.

'motorcyclist' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
