Handelbar Shaking

First let me state for the recorder, I am a woman who was use to a man doing all the repairs. That is not the case any longer so now it is time for me to learn. I am ready and willing so any advice will help my ignorance.

Today while riding I was in 1st gear going about 45mph. I was approaching a red light. So I took my hands off the handle bars to slow down and adjust my backpack. I looked down and noticed my handle bars where shacking. I checked the tires pressures and they are good. What next should I check?

could be anything... road surface... neck bearing.... yada yada yada...


technically you shouldn't take your hands off the bars... adjust your backpack at the light when you stop....

yeah try to keep at least your right hand on the handle bars at all times, because if someone were to pull in front of you or cut off, could be very bad news in reaction times.... I'm guilty of going no hands sometimes, but i try my hardest not to!

but sounds like a bad road surface, try it again somewhere else like a parking lot (where its safe) and see if the same thing happens

My '02 gixxer 750 did this from about 650 miles on. Depending on the age of the bike and the quality of the road surface, it might just do that.

I'd venture to guess that your front tire is cupped. Even though it may look fine visibly, ie still have tread on the tire...the front end will shake if this is the problem. You need to take the bike up to Motorcycles Unlimited or some other reputable shop and get their opinion.

That's what I'm guessing, too. With that said, it's just a guess. I doubt it's the head bearings, though, but you never know until we can look at it.

X2, my bike was doing this when my front was wearing out.

pressure, age of the tire, condition of the tire and the alignment of jupiter and mars all are factors.
buy a new tire and you'll probably find zen.

Lots of bikes do that right off the showroom floor. Goldwing riders (not sure about the 1800 series) try it and report back. My wing was bad. The FZR-1000 and V-max were also bad. Leave 1 hand on the handlebar and it will go away. It is a fairly common problem reported to a service writer in the '80s and early '90s.

I agree with a couple others, prolly a chopped tire, run your hand, palm wrapped around the tread of the tire run it back and fourth and feel for hi/lo spots, if U can feel or see any than its gonna shake slightly sepecially at speed and especially with your hands off the bars, If U wanna come by my shop in Tomball I will check it for U for free, lmk,gl, prolly no big deal if its chopped unless its real bad usually U would feel that with hands on also

yeah as others said...

1. front tire issues:
- some stock tires have incredibly long milage, and look "good" but can be out of whack. (but for reference ANY TIRE can look "good"

- check air pressure

- tire may be cupped, or have uneven wear

- could be balance issue..less likely but it could be.


2. steering head bearings:

- need to be tighted up (not properly set since last removal/check)

- worn out bearings

- possible an accident may have tweaked the steering head dimensions. (if in an accident)


more than likely its just the tire getting worn...typically, if everything else checks out.

i had an older taurus that for a while had a crazy shaking steering wheel. all my was straight and there was nothing that should make the shake like it did. oh yeah, and there was a ****ing football sized lump in the left front tire that i somehow missed the first 5 times i gave my of a car a looking over.

check out your tires and check to see that your own weight is consistant and you dont have sudden shakes all all over
