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..

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!

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.

@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...

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.

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.

Greetings from Chelmsford (no Essex boy jokes please!). I've just upgraded my 50cc scooter to a YBR125 and wish I'd done it years ago! So far the YBR125 seems like a great bike, the only problem I can see is that it's developed a squeak at the back while I'm riding but I'll post a question in a more appropriate forum on that!
