Never buy from ktm for bolts and screws, your just throwing money away. I remember someone once posting a pic of an Aprillia washer, the sort they would give you for free at a mom and dad hardware shop. The cost was $28!!! Wtf! And you paid for it! Idiot....
But anyways, euro bikes seem to be notorious for not be torqued up properly, so the rule is always, Run the Spanner Over the Bike straight away. And a bit of blue loctite or similar is a good idea, just not on plastic as it rots it very quickly.
