Front tire wear
FWIW, pretty much every motorcycle front tire I look at is cupped. Not just Rockets, I mean when I go to a meet, and look at peoples bikes, the ones ridden a lot are always cupped up front. Crazy, it holds true for all types of bikes, and my own Pilot Road 2, a "sport touring" tire, was cupped badly on my 'Tona at 13,000 miles with at least 1/2 the tread depth left.

I think it's just a combination of factors, the mains one being; under inflation, aggressive cornering, aggressive braking, and very soft compounds on most front tires.
 
I've had several Avon Cobras on the front and don't recall any cupping on any of them and they've always held a nice curve right across with no flat spots.
@Wrecka it would be worth checking your steering head bearing doesn't need to be tightened as that can also cause shaking. New tyre should make a world of difference but it would hurt to check anyway.
 
I think i over exagerated shake mate, more highspeed vib through the bars , has gotten worse over time , there is also a good amount of vibe through the bike when reving the engine stationary , my guess is that throttle bodies are way out of sync , causing vibration , is that feasable ?

Thought I'd confirm what 'cupping' on a tire meant so did a google search.




I don't know what you guys are smokin, I've NEVER seen this happen to anyone's tire.

I think cupping is a badly thought up term for this type of wear , scalloping is more appropriate
