Handlebar shake

Post by Jameshambleton on Sun 13 Mar 2016, 8:05 am

I had my front wheel balanced and it's balanced as when I have put the bike on the main stand, removed my front caliper and I can place the wheel in any direction and it will stay still. 

When I'm riding along if I let go of my handlebars they shake to the point of almost tank slapping, does anyone have any suggestions on what could be causing it?

uneven fork oil/leak, caliper dragging/disc warped, tyre pressure, tyre condition, head bearings, triple clamps tight. issues with the rear can also affect the front, tyre pressure, shocks tight, swingarm bolt.

Top boxes can also exaggerate these problems.

Could it be  front wheel bearings  or  headrace bearings(loose or warn)

This may be a bit radical, but can I suggest not letting go of the handlebars?

Mine do the same, and I've not yet been able to find out why.

If you have a top box fitted this will happen regardless of everything else being spot on.
I just keep hold of the bars Very Happy

Little update, if I let go of the bars when I'm doing 70 and 80 and even 90 (km of course) then there is no handlebar shake, anything under these speeds and it shakes really violently

This came up ages ago. From experience worn tyres (esp rear) don't help and as said, topboxes aren't great for stability either.
Most bikes have a little shake at 30 odd as the gyroscopic effect of the wheels kicks in, at faster speeds then tyres/topbox, assuming tyre pressures are ok.
