I have a 2010 SG and I just put a new Ride wright 21 fat spoke wheel, tire and rotors on the bike and it is hopping at 75mph took the bike to my local dealer and the told me the wheel is balanced. My question is can the problem be in the front suspension?

 

Let's stand back a moment! You changed your wheels. Did the bike hop with the previous wheels? If not, then your new wheels need balancing! You can confirm that yourself by jacking the front wheel just off the ground. Lever the brake pads off the discs, so the wheel runs freely. Turn the wheel and let it rotate slowly until it stops. Use a marker pen to mark the low spot after it stops turning and repeat a few times. My money is on the low points being similar every time!

Get that done first. You can balance it yourself by using balancing beads or conventional wheel weights.

 

Don't overthink this. Vibration started after new wheels..... It's the wheels!

 

i had this problem before and the wheel was balanced. turned out the wheel was not perfectly round (laced wheel also). like grbrown said, jack the front wheel off the ground. and after your done with his test, do this: set something up so that it is right at the edge of the wheel. it can be something as simple as a stick with a nail through it. just get it set where it is at the edge of the wheel, somewhere. then slowly rotate the wheel. see if the edge of the wheel is always where the nail points, or did it rotate off of it? if it rotated off, the wheel is not round.

 

If your front fork oil is low, your wheel will hop more than usual from bumps on the road.
Is the hop a steady hop or just excessive hop after bumps?

 

I'd also thing the tire is out of balance.
Other possibilities in this order; bad tire, wheel not trued.

 

I would of thought it was the wheel or tire also but this is the second wheel and tire combo Ive tried the first was a 21 DNA fat spoke with a metzeler tire and it also hopped only it did it at 65mph

 

It could also be the tire. Might want to check pressure and see if there is a warranty on whatever brand tire you have. I'd rebakance with Dyna beads.
