I think the term most commonly used for this condition is cupping. I'm not sure what causes it but it could be a frame alignment problem, a fork alignment problem or a rear wheel alignment problem.

Hi, i´m new in the forum, and i don´t speak english very well. I´m from Argentina and i haven´t this kind of foum here.

I have a ´96 zx6r.

When i touch the front tyre i feel a lot of waves in the rotation way.

I think that is a suspension problem... But i don´t know what i need to do..

Some help please...

Sorry for my english......[:I]

First of all don't apologise for your english, I cannot speak Argentinian at all so you are one up on me!

You do not say what tyres you are running, on my 98 when I used Dunlop 207's they would wave, cup, feather whatever you want to call it. When I changed to Michellin Pilot Sports the problem disapeared. Everybody has favorite tyres although I will never use Dunlop again because of the problem you are describing.

This of course may not be your problem although if the wave wear patterns are the same on both sides of the front tyre I do "NOT" believe an alignment problem is the cause.

Good Luck

Afterthought:

Incorrect tyre pressure (low) can also cause this!

mine did that too but it was from being worn out. maybe it's just time to get new tires.
