Brychan Posted February 25, 2011 Posted February 25, 2011 Hi everyone, I'm a noob so please treat me gently! I've recently bought a YBR125 ex-demo from my local Yamaha dealer (50 miles on the clock!) and it's a great bike except that it's developed a squeak while I'm riding that sounds like it's coming from the back wheel. It seems to appear over about 10mph. If I spin the back wheel with the bike on the stand there's no squeak there. Has anyone else experienced this / know what it could be please? I guess I'll have to take it back to the dealer but that's such a pain..! Any advice gratefully received.
Moderator Airhead Posted February 25, 2011 Moderator Posted February 25, 2011 Try oiling the disk brake Only joking of course Does it even have a disc at the back?
Brychan Posted February 26, 2011 Author Posted February 26, 2011 Yeah, tried that but the bike wouldn't stop..! It has a drum at the back, not a disc. I don't think it's being caused by the brake as if I apply the back brake while it's squeaking it doesn't make any difference.
Moderator mervin Posted February 26, 2011 Moderator Posted February 26, 2011 Maybe a stupid question but have you oiled the chain lately check there is nothing rubbing I:E tyre in mudguard last of all is there a mouse hiding under the seat
Brychan Posted February 26, 2011 Author Posted February 26, 2011 @mervin: Thanks for your suggestion mate, I'm going to try oiling the chain when it stops raining to see if that does it. I only picked the bike up from the dealer on Wednesday but I guess I shouldn't assume that they had PDI'd it properly!. If it's still noisy I think I've got a mouse trap around somewhere...
Ddraig Posted March 1, 2011 Posted March 1, 2011 Hi. Another newbie here. Also have a ybr125. And it has an intermittent squeak/squeal, a rotating sound kind. I have ruled out the chain, as when it finally stopped raining not so long after I picked it up, I gave it a thorough treading, and even with that every now and then it comes back. Tried the wheel spin / wiggle to test the bearings and they seem fine, and checked out the disc, no scoring so nothing trapped and its not the rear drum as it still makes the noise with the brakes applied. Not sure what it is as it only occurs every now and then. If I come across what it is, ill let you all know.

Mine is going into the dealer tomorrow for them to have a look as I also tried the stuff you did with no luck. I'll post what they find.
Ddraig Posted March 1, 2011 Posted March 1, 2011 Hope its not a big n pricy . Fingers crossed its a. Simple thing
Brychan Posted March 2, 2011 Author Posted March 2, 2011 Hope its not a big n pricy . Fingers crossed its a. Simple thing Dealer couldn't find anything wrong!! The squeak is really quiet now so I've re-oiled the chain after a 4 mile ride so it would be warm this evening in case it still needs some lube. Lets see what happens on my way to the station tomorrow morning!
KirriePete Posted March 3, 2011 Posted March 3, 2011 Logical thoughts: Squeaks come from moving parts rubbing together What moves in the rear wheel and could rub? Chain/sprocket Bearings Brake back plate Axle/spindle Wheel vs bodywork/swingarm So get lubing! Or clean the dust out of the brake drum (good housekeeping anyway). End of logical thought, possible start of drunken rambling .... or not.
Georgiev Posted March 14, 2011 Posted March 14, 2011 Hi, Sometimes I have the same noise on mine. I have ruled out the wheel bearings , break and chain, because I have disassembeled them recently and applied enough grease. I believe that noise come from swingarm bushes or/and shock absorber bushes. It is like rubbing wet rubber on metal. Some non-agresive grease may help. Hope this helps.

Hi Georgiev Thanks very much for your reply. The squeak on my bike seems to have quietened down on its own over the last few days. Maybe it was just a new bike thing.! With my luck it'll probably start up again tomorrow and bring friends though..
Mark K Posted March 14, 2011 Posted March 14, 2011 It's not a new bike thing, mine's an early 09 model, and started squeaking about a month ago - and I can't find it either
Badgerofmight Posted June 3, 2011 Posted June 3, 2011 I have a less than perfect 07 YBR, but on occaision I heard a squeaky sound from the back. Turned out that the (once shiny) metal fairing bit on the exhaust was creaking if I gave it a wiggle, or indeed if the thumping engine gave it a wiggle. You never know, it might just be that!
