990 Adv R wheel vibes

[hhansum]

I've put on around 1100 miles on my '12 990 Adv R. Since new, the front wheel goes through a speed stage where it seems to be out of balance or out of round. It's the 30-45mph ish range. Wether accelerating or decel, it just shakes at those speeds regardless of road surface. The thing is that it smooths itself outside of that range. Fine at highway speeds. At the initial dealer service appointment they re-balanced the front wheel yielding no improvement. The dealer is far away so it's a haul to get down there. Anyone else experience this sort of thing?

Sometimes it is the tire itself, this happened to me and we surmised at certain speeds the belts within the tire were expanding just enough the cause the shimmy. This happened with two different Scorpians. If you have a different front tire throw it on and see what happens, if not you can put a few ounces of Slime or Ride on in the front wheel. I have done that to balance a stubborn wheel worse case.

Just a thought.

i made them replace my front tire, no more wobbles. this has been a well documented problem with the pirelli scorp front tire.

Sometimes you can break the bead and rotate 25 degrees . . . And it helps . . . But not in all cases. Worth a try if you can't get it replaced on warranty.

I prefer TKC80's on the front due to this issue. MT90 rear has been great . . . Even with the TKC80 front.

If you stiffen the rear suspension . . . And drop the front a bit in the triple clamps . . . It may help. Also, try scooting closer to the front to get more weight on the front wheel . . . Since your seat is flat.

I like scooting back myself . . . Which may cause a 30-40 mph no-hands wobble.

Thanks for the good advice all. I've got a sneaking suspicion that its a faulty front tire too. Time to put a little more pressure on the dealer. See if I can get the tire replaced.

I have a 2012 990R and does the same thing @ no hands shake. I figure its the tire and they will soon be gone so good riddence.

I also have a 2012 990, and had the same issue. The dealer did re-true the front wheel and that did help quite a bit. I still think the stock tire is slightly off, not bad, and like others have said, will replace it with something else once it is worn out.
