Thunderbird Oscillation

Hi All

I noticed in the summer that my trusty old Triumph Thunderbird was oscillating when doing under 30mph but as the bike was heavily laden and we were two up I thought that was the cause.

I've recently noticed that its still there and could be getting slightly worse. The old girl has a large screen and the head bearing and front tyre seem fine.

When moving over 30mph it disappears

Any ideas what this could be?

Thanks as always

Rushy

Have you checked the rear wheel,tyre fitment,swinging arms and suspension? Also are you talking spoked wheels?

My VFR has started doing the same thing - it hapens as my rear tyre squares off.  It happened with my BT-021's and I have just reached the same stage with the current 023's.

Well I never - yes the rear tyre is squaring off but a fair amount of tread left yet! What a bummer!

Many thanks for the answers guys!
