@Torquex2 as a '14 Touring owner from new (3 miles on her when she became mine), I have only experienced this weave above 120mph and attributed it to either my bikes loading (I'm guilty of not evenly filling the panniers) and/or my tires... or a combination thereof. It's been a long time since I've had the ability to go above 100... and she's been rock solid.
This of course doesn't help or compare to the new R3's. I've probably missed several posts with your issue as I'm in the missed of a career change and we are temp living in several locations, but if the dealer is not helping I'd formerly reach out to Triumph Corporate...
