Strange Vibration Under Braking

Hi Guys
Im a little concerned with my bike at the moment. She is a 600RR 05 Model and when coming to a stop sometimes, just before I come to a dead stop I get a strange vibration coming up thru the clip on's as if the wheel is shuddering. This only happens from time to time but latley it happens more often now. I have checked for free play in the head bearing's by doing the push and pull test on the front of the bike but it's all good. Brake pads are still good with alot of pad still left. Front Tyre is correctly inflated and in good nick too.

Any ideas on this ? Im too scared to ride her now cause it might be something serious and I could end up kissing the tar

i have the same thing that i was worried about...but i think the vibration you feel is from the rubber lines giving in a little under heavy breaking and thus making the pads chatter (they work on friction). I hope someone else can give me some input as well...

I get this too. I even took mine in to the shop for it. they couldnt find anything wrong. I also notice a small looseness when I am walking the bike and tap the front brake. I think it is related.

I have a feeling its is due to the floating type brake pads.

The weird thing is sometimes it's happened under normal braking conditions too. It has me very worried now, Im worried that the previous owner might have been wheelie MAD, could something like this be caused by excesive wheelies maybe ?

on a brand new 06 model too...... dam now im really confused.
Could it be the "type" or "make" of brake pads we are using that could be causing the shuddering ???

it happens on bikes with all stock parts. brakes work on vibrations, they are really small vibrations that cause the breaks to not lock up. I will switch to steel braided line soon and let you know if it helps any. i wouldnt worry too much about it, it seems pretty common among riders.

that is one idea, let me know once you have upgraded ur lines if it made a diffrence.
The good news derived from this post is.... that I can ride her again. Was too scared to ride her incase it caused more damage later on but this seems to be a common issue amongst the honda owners and riders.

So as they say only time will tell I guess

well enjoy the ride!!!

if anyone has any opinions on the problem lying in the pads let me know, ill change them with the lines. I heard sometimes the rotors and pads get glazed and problems can arise. just a thought, do not know about bike.

i had this issue before on my new 06 when i got it. only reason i can find is that your brake rotors and pads are still cold when this vibration happens. to solve the problem, when you first start riding (first 2 minutes or so) always warm up your front and rear brakes by applying the both brakes slowly and continuously (when you're breaking at a stop or intersection). this warms up the rotors and pads and seems to remedy that problem.

I say its the brake pads themselves, gripping the disc then slipping. I had this happen when I changed brands on my old bike.

Its prolly your suspension, even tires can cause vibrations that feel like a warped rotor.

No more mod listing, shits is STILL too long

Mine does this too, but only under heavy braking at like 60-70. Is this normal?

My 06 does this too...cold and hot. It happened the other day going down steep hill, kinda worried me a bit, but seemed to be ok the rest of the day.
I am switching the lines and pads this weekend, hopefully it fixes the issue...will let you know!

Has anyone try hard braking with the clutch disengage?
I only notice this under hard braking with the clutch engage.
where the RPM doesn't match the wheel speed causing wheel hoop.

I don't get this front end chatter anymore After tweaking the suspension and
down shafting correctly to match wheel speed with engine RPM Under hard braking.

The clutch on these things is a little rattley and much of the bike's weight and stress is prone to the front, particularly under brakes. You are feeling the engine vibrations through the bars. Pull the clutch in and you should notice it a little less.

This happens with the bike in neutral, it usually happens after a hard breaking right before i come to a complete stop. I think it mught be the line/pads/and just plain friction. i am not too worried but i hope the braided lines and pads help...

Braided lines will make it more noticeable if anything. The idea of braided lines is to provide a more direct transfer of force.

but the funny thing is that it has only happened half a dozen times to me. Its kinda rare and nothing i worry about. I am not going to install the lines for this purpose but I will see if it makes it stop, if it increases the frequency ill let you guys know. thanks for the input...
