tank slap

[Daz]

hi is there anyone who might know why from about 70mph if i change lanes or get a bit of side wind the front of the bike Z9A4 starts to wobble and feel light . i have had the head bearings checked and there ok , i've got 2 odd types of tyre , or would a steering damper be a good idea .would like some advise PLS. DAZ.

Zeds were fitted with ribbed (directional) front tyres, this helped stability

The steering angle is quite sharp but helped with the 19" wheel. This trait is just one of the charming charateristics of the Zed
It may be worth checking wheel bearings, spokes & pressures. The wheel alignment & maybe even frame trueness Then fork oil levels.

A steering damper may help, but is only going to disguise the real problem.

Daz, what tyres do you have on? These can make a huge difference.
Check out what Pigford says, also the "trueness" of the wheel.

also check the swingarm bearings/bushes. many years ago i had a suzuki gt750j that weaved more than they normaly do. One time i almost decided to head for the grass verge on the motorway and jump off. swingarm bushes were knackered. What happens at rear can affect what happens at your other end.

Cheers Pigford and the guys for the advise. I am going to embark on getting 2 new matching tyres and at the same time I will ask them to check the things that you's have mentioned. I'll let you know how I get on.
Thanks Again
