I've searched on this forum and others and it is either

* Loose suspension components
* Warped Discs
* Unbalanced Tyres

The tyres were new (and I presume properly balanced) when I bought it and the shimmy was there so I can semi rule that out so I'm down to warped discs or loose front suspension (except the front control arms)
