this is something that needs fixing RIGHT AWAY! So many possibles, tire out of balance, out of round, warped wheel, bad fork seals, one bad fork seal, wheel bearings,just for starters. And as blurplebuzz says...have a qualified mechanic check it out.

I would like to add one more concern to look at. Rear shocks may not be adjusted to any added weight or you may have exceed the weight limit for the shock setting. My wife rides a C90T and she experiences a high speed wobble when the bike is loaded with luggage and fails to adjust the rear shocks. Something to consider, but like Rex the RoadDog and Blurplebuzz says Have a qualified mechanic check it out.

Any results on cause yet?
I agree with Bailout, Tire wear and balance. Bearings will usually not give you a bounce they scream when damaged.
I agree with a Mechanic to look at it.
So now it's been over a week and we still don't know if Grubb found the problem. Come on Grubb!!!!! What's the verdict dude? Inquiring minds want to know.

went to shop they took for a ride said it was low tire pressure they aired them up but to me still does it might think about new tire thanks everyone for the input
I hope it is fixed but Me is doubtful of the tire pressure fix. I once had a new tire installed that reallt should never have been put on a bike. 5 ounces out of balance before any corrections. It was a BAD and WARPED tire that the dealer never should have installed. It was so warped it actually distorted the laced wheel to make it look like the wheel was the problem.
