Serious Front End Judder

I am posting this thread on behalf of a friend although I did suffer from a similar problem myself.

After approx 4500 miles my GSX-R 600 K5 started to suffer from front end judder under braking (beit heavy or moderate braking) speed was irrelevant as it happened at high speed and moderate speed. You could feel it through the handlebars and through the brake lever. I never got to the bottom of what the cause was (although I did report it to my dealer) as I decided to upgrade to a 750 K7.

Unfortunately a friend of mine with a GSXR 750 K5 has also now got the same problem.

We have checked the discs for warping (using a DTI and not just visual), wheel bearings and have changed the front pads but with no improvement. In fact it appears to be getting slowly worse.

I have researched forums on the net and have found reports of front suspension issues with the K5's.

An email has been sent to Suzuki and we are waiting for a reply. In the meantime can anybody throw any light on this issue.

Many Thanks

this eems to be a common problem on a lot of k5 model suzi's

it seems the little jap bloke in the factory only had 1 can of grease for the entire production run of bikes,so grease every thing all bearings especially the head and wheel bearings,as they seem to seize at the mere mention of moisture

OK. my mate just had this problem on his K4 thou.  After buying second hand discs, whcih were warped, he tried my mates 750 discs on the bike and the fault was cured.  After phoning Crescent he was told quite abruptly that all K3-K4 discs are absolute sh*te.  So whether that runs onto the k5 models aswell I don't know.

Just a tip to you all.  If you do ride hard and really heat the discs up.  If you come to a sudden stop, don't hold the front brake on in one spot on the disc.  The heat will build between pads and disc whilst the rest of the disc is cooling down   =   warped discs.   I had two sets on my rr, and after changing my riding never had a problem since.

Just a thought

What is the rear tyre condition?

Have you got the suspension set to rider, or is it just roughly set up?

Judder from front brakes

I have had this on a new 2004 fireblade and my current GSXR750Y which I have just put new EBC pads and discs on.  It only happens when nearly stopped.  Horrible judder and grinding sounds.  Brakes superb for feel and power other than that.  No idea what it could be.
