Bike Chatter...

I just put 700 Miles on my bike, still have yet to get my 600mile service yet. But i will get that done on Friday. Anyways, As i was pulling into my street going about 60mph, cuz i live next to a highway, I start to break front and rear, and then i start to feel this Chattering in the front breaks. :confused: So i thought i was going crazy, so i pull into my street, and there it is again... It feels like its coming from the rear, and happed when i used my breaks at about 10+mph. Anything under that it was fine. OH and also is it normal for the bike to have abnormal vibrations when i put it Neutral? Im guessing not, but Since all these problems with the R1 seems to be coming up, Who knows if its normal. :dundun:

Hello mate ive just had mine in to my local dealer and they have ordered me new disks and pads.Mine has been juddering at high speed mainly but not all the time.When the mechanic took it out he reckons he was feeling it at slow speed.Me bike started doing this just after me first service.:mad:

my bike has 600 miles on it and my front break makes like a sanding noise, I´m hopeing it will go away with more use.:riding

Best wishes to you all for the New Year ! My friend David had bad chatter on the front under hard braking into corners we swopped many parts and found the problem to be the forks, we have had k-tech internals installed with spring, and new oil all done by one of our suspension guru's. There was something with the hydraulic stops causing the problem, anyway it's now sorted and he is happy.

I too have some chatter under brakes... I had a Magura 190 Radial on and some Hel brakelines. Went back to just the stock radial and the chatter lessened but didn't go away, still there under hard braking. I am none too happy...

no chatter here, but I plan on going to steel lines soon

I have this same problem on mine 07. So is it the forks or the rotors?

i had the same problem in my 07 got my 08 same story is it just a matter of finding good suspension set up or is it tyres?

Chattering here too, on a stock '08 with 5000 miles on it. And it's been there almost since it was new, and it's getting worse. The dealer haven't been very interested the times I've mentioned it, but now that I've gotten used to the bike and riding again after more than a decade without a bike, it's starting to seriously affect my "inspired" riding - so I really need to get it sorted. I've been thinking about new linings and a resurfacing of the rotors with lots of acetone and a light sanding. Any thoughts on sanding the rotors? http://en.wikipedia.org/wiki/Brake_lining "The lining may also become contaminated by oil or leaked brake fluid. Typical symptoms will be brake chatter, where the pads vibrate as the lining grabs and releases the rotor's surface. The solution is to repair the source of the contamination and replace the damaged pads."

When you say the dealership is not "interested" What does that mean?? The bike is under warranty right? Did they address the problem at all?? Not likely to be from contaminated pads....Do you see any unusual residue on rotors or pads? Is the chatter from the rear or the front brakes?? You see any hot spots(bluish tint) on rotors?? Many questions....If dealership can't answer... I'd be thinking about upgrading brake system...IMHO...

It's from the front - I only use the rear brakes in the wet or on poor surfaces. It's a small dealership in a small town in Norway. They're mainly selling cars, but have dealership agreements for Yamaha an Suzuki aswell. Understaffed and busy in season, and obviously needs insistent customers before they take action... I mentioned it at the 5000km service with nothing but muttering in response, and didn't bother to argue because it still was infrequent, and as an inexperienced rider with more than a decade passed since I last rode a bike, I settled for it and contributed it to normal occurances. I need a new rear tire and will order it from the dealership this monday, and then there's no mercy. Lately as I'm driving harder and the problem increases - it's starting to scare the crap out of me sometimes...

Well I just sanded and cleaned my rotors and pads and put the axle, pinch bolts and calipers back to spec. Lets see what happens, I still havent tested it. One thing I did notice is that this started happening ever since I adjusted my suspension. I dont doubt that this has something to do with it but the bike feels/handles the way its suppose to handle. So all in all I dont see why we should compromise handling for braking or vice versa. Im really starting to be disappointed in yamaha. Heat, broke rearset, mirrors vibration, stalling issue, lag in 2nd due to ecu and now brake chattering!!!!! What else??????? I hope they read this stuff

I also read a couple of threads in the WERA forum talking about this issue. One guy said he changed his internals on his forks and the problem got solved

I also read a couple of threads in the WERA forum talking about this issue. One guy said he changed his internals on his forks and the problem got solved yeah i was thinking it was a suspension problem myself but un sure has anyone else soled this problem? are all 07 08 r1s this way under hard breaking?

yeah i was thinking it was a suspension problem myself but un sure has anyone else soled this problem? are all 07 08 r1s this way under hard breaking? My initial thoughts is that it is a pad and rotor problem, perhaps compounded by the bikes tendency to wobble and be a bit nervous when stressed? As a curiosity... On the original front tire, the bike only got nervous and wobbling in hard accelerations out of turns still leaning over. But after I got a new Michelin PP2 ct in the front, it wobbles noticeably on hard acceleration on the straights aswell... I dunno what's up, but it needs to be fixed. It affects my confidence and safety.

we swopped rims and brake pads and only the one bike had the problem once the forks were re done problem solved. I'm no expert but something was said about the hydraulic stops in the fork. Good luck

Well here is the outcome. I sanded my rotors and pads (really, really well) and the problem seems it has gone away, but there was moments that I slightly got it but very very minor. I sanded the rotors so well that I even took them off the rim to sand them

Yeah I got my bike about 2 months ago and I have put about 1500 miles on it. I just started noticing the chatter as well. It usually happens in lower speeds like coming to a stop sign. Its definitely in the front. Not sure what it is. My bike is under warranty so I was wondering what to say to the dealership when I go in, cause it dose not always happen and I don't want to look like a dumba**. :dunno:dunno

Just wanna ask you guys a little, am riding an 07 r1 with 20,700km on it, been around 15 months already. Yesterday when riding home about 120km/h i hear this loud abnormal noise from the speedometer, this goes on. When slow down the noise disappear when pick up speed to 115km/h and above it starts again. Anyone experience this befores?

Try cleaning your discs/rotors with a fine emery cloth/abrasive sheet and reface the brake pads on a flat surface.Also check your headstock bearings bearing for excessive slack.Are you into wheelies or stoppies? If you have been a bit over keen with some cleaning product around the bike you may have accidentally contaminated the disc/rotor surface. Ther is nothing wrong with Yamaha standard suspension for road /light trackday use and upgrading for road use is a bit excessive. There is a difference between chatter and brake vibration ,Chatter is something you will be able to dial out with suspension adjustments and does not happen in normal road use,where brake vibration can be a regular problem if you ride around town a lot and brake lightly and glaze the pads or are a bit careless with cleaning product around the disc / rotor surface area .Also clean around the rotor fixings where the disc attaches to the carrier,this is supposed to be a floating disc but they more often not floating on all rivets.spray around the fixing rivets with a quality brake cleaner and then blow out with an airline and they should loosen up a bitwhich may help.be careful when using the cleaner as some can damage paintwork . hope this helps

Wow. Never happened on mine all stock or now with aftermarket suspension front and back and steel braided lines with stock pads still. Mine is solid under braking just like my 04 was.
