High Speed Wobble

[edrawba]

I am experiencing a wobble when I get up over 100 mph. I feel it in my seat, not my handlebars. I recently installed a new rear tire, but it was balanced. I checked the old wheel bearings and they were in good shape. It didn't wobble before I put the new tire on. If I am going around a turn it is worse. It feels like the seat is moving side to side. How can I fix this problem?

sounds like your rear wheel isn't 'square'....as in, the adjustment is off from side to side. the axle adjusters and hasch marks on the swingarm arent always the gretest things to measure off of, I would suggest measuring from the center of the axle to the swingarm pivot center on both sides. If they are different, adjust as necessary and take a test ride. If they are the same, I'd check for a bent wheel or axle.

or just ride slower.

Teddy... Can you explain alittle more on how to measure to insure the axle is straight? I'm thinking what your saying is to measure from the swingarm mounting area bolt to the tire axle? I assume you mean with a yard stick or long ruler? That just doesn't seem like a accurate way to measure or atleast very easy to get precise. Or am I missing something here?

Ummmmm....YOU shouldn't have to fix the problem..... take the bike back to who installed the tire and tell them you think THEY fugged up.

This is the thing to do. Dont touch anything till you take it back.

you could also lay a straightedge against the side of the rear sprocket, and see if it looks like the chain runs in a straight inline with the rear sprocket.
