Brighton, TN | NOPE, normally just the hard wear bar in the center makes its appearance. Sometimes some cupping, but normally , just the raised bar in the middle. This just means you take corners with a grin on your face. That or ride some more HIGHWAY to wear the middle bar down. |

Has anyone got over 8000 miles on the front Dunlop tires without seeing a weird wear pattern?
08 Victory Vision Tour 16442 miles
I put 14,000 on mine with even wear. |

my wobble did not start until i put new tires on my vision, I had 21000 mile on my original tire and never had a problem until I replaced them i just got a call from my dealer and they have narrowed my wooble to the stearing tapered bearing! they told me it is a 8 hr job to change them and is not covered under warranty, makes me wonder why i paid for a 5 year warranty? |

| Anyone seen this Vision crash yet? I cannot see anything in the road to have caused this accident, so am wondering if the wobble was caused by a bad tire as discussed in this thread. Any other ideas??

Hard to tell 100%, but looking at the little bit of right hand you can see at 34-35 seconds, it appears that the rider got on the front brakes prior to that turn. Not sure if he locked it up or just a tad too much. I understand that wobble only occurs with too much weight on the front (i would assume general braking physics apply to this as well). |

Northeast Ohio | Watching the video about 20 times now, watch from 25-35 sec. The rider is HARD on the front brakes (you can even see it nose dive around 35 sec) as he sees the left curve ahead. |

Rockford, IL | I've watched it several times now....grabbing the front brake caused this. You can clearly see the fingertips go over the brake lever and then you can also clearly see the front dive down very hard and then start the slapping. Not a question in my mind. |

| Yep, definitely VERY HARD on the front brakes as if you watch the riders shadow on the left side of the video, you can see him pitch forward just as the handle bars start to wobble. Another indicator that the front brake was being grabbed hard is that when the tires hit the gravel on the side of the road the front end washed out from under the bike and something like that only happens if you are hard on the brakes. I have seen a similar thing happen when someone I was riding with went off the road near Deals Gap, the only difference was that they let off the brakes just before going off the asphalt and were able to maintain control and ride it out. |

+1 on that Chris. Oddly, I think he would have been fine with that curve at that speed. Not sure if there was something else he saw that I didn't on the video. |

What it a Tank Slapper and what cause it? I have been riding since I was a kid and heard this many times, but never known what it does while you are riding.

LaPorte,Tx. | I believe it is one of the guys that posts on here, so I'm sure when he is ready, he may tell what happened. I'm glad he is on the mend and will be ok.  |

Give him my best! I cringed when I saw that wobble and knew what was about to go down (no pun intended, seriously).
He didn't appear to be busted up too bad for a 70+ mph crash. And while his life is more important, the bike looked to hold up better than I expected. |

New Bohemia, VA | it would be good to hear what happened so we all can learn from it. seeing that he was moving right away made me feel better and I'm sure he's hobbling around, hopefully, and maybe even back to riding... |

| I see the consensus is a hard pull on the front brake as a problem. That makes me nervous.. I did not know that was a problem. What am I missing here? He's goin fast and hits that brake to slow... I assume he should have used the foot, but can you veteran riders explain that to me?
Thanks |

New Bohemia, VA | without knowing every detail, which may have been even forgotten or misinterpeted by the rider it is impossible to tell. The assumption from me is that he in deed did brake hard with the front, on uneven road and then got spooked on the turn and headed fro the side. Nothing has been said of a front blown tire, but that is possible if he picked up something in the road.
the bottom line is to know how to ride in all circumstance beyond a best guess, know who to brake your bike using both front and rear brakes.
I think the thing the interest me is that there was nothing in the road, and it was a slow sweeping turn easily to nagate at nearly any speed, so what did happen? |

LONDONDERRY NH | I really don't think it was a tank slapper-just bad reaction to a corner.
now this is a tank slapper

Bad Front End Wobble- Anyone ever?
