High speed wobble - Ducati.ms

HATTMANX · Sep 29th, 2011, 10:47 pm

I read some older threads on suspension. Is the suspension being to soft causing the speed wobble over 100? That seems to be my "grasp"...? Guess I just won't drive over a 100mph ...

That wobble wouldn't likely be caused by suspension. It's worn front tire...or air pressure too low in the front....or most likely it's loose head bearings that need lubed and adjusted.

....or not following the proper sequence when tightening your front wheel after removing it.

I had the same thing. Above 100mph I would get a slow "wobble", sort of like a "weave", but not a "swagger" or a "wiggle", I guess you could call it a "zig" but you wouldn't quite call it a "zag".

....but I digress....

After realigning, my "sway" went away

You say that with some strut.

That might be the problem since I just had new tires put on....

As mentioned in another similar thread someone suggested letting up your grip a bit when it starts to wobble and wallah...mine goes away. It also helps or is less prominent when your mirrors are folded in.....

Cheap shitty front tires will do that. Get the expensive sticky stuff, give it some gas and you'll be fine

hi guys i found that my hyper would do just that i thought since i had come off it i had damaged the front end somehow ,, but i found if i sat different and put more weight on the front end it was more stable also its right about the mirrors ,,,, soppose its a wide set of bars acting like a sail ?? cheers

What is the proper sequence ?

also depends on the geometry of the bike. I've raised the rear of mine and it wobbles a bit at 180+ kmh. It is now at 5 threads showing, didn't wobble at 4 threads, but bottomed out earlier so until. Also, a shitty tire will do this, or differently calibrated front forks.
