I started hearing some odd noise from the rear of my GTS this week, rather intermittent so hard to track down at first. It's a high pitched chirp, reproducible by rotating the wheel when on the center stand. There's just a bit of extra friction it seems at the time of the noise. Not sure what happens under power, but did notice it coasting in to park.

Just had the wheel off for a new tire this spring and brakes seemed good at 18k miles.

From what I can ascertain from searching around a bit, it's not altogether rare, and generally benign. So, have to decide what to do. It's liveable at this point, and if perchance it's a temporary thing I'm happy ignoring it until I pull the wheel for some other reason. OTOH, if I do pull the wheel, is applying something like COPASLIP useful? Replacing pads if there's some wear on the originals?

Guess my biggest concern is if there's something else that's more critical to check.....

With a recent rear tire change, perhaps the axle bearing in the shock mount plate (aka "swing arm" )took some abuse?

My guess is also the bearing in the swingarm. Fits all the symptoms. Can be a DIY fix if you're willing to invest in a "blind bearing puller" to get the old one out and some carefully-sized bolts, nuts, and washers to squeeze the new one in.

FWIW did a tire change about 1K or so ago. Wasn't easy getting it off.

Weird, though, I can feel resistance at the squeak when rotating the wheel....of course the bearing's moving too.

Guess it doesn't hurt to pop it off and have a feel. I assume just rotating the bearing by hand should be the tell, no?

I've got the exact same issue with my wife's 2021 GTS 300 Super. Bike only has 1400 miles on it. It's going into the shop next week for this issue.

Will be interesting to see what they come up with. That's pretty low mileage. With my 18K and a few tire changes, wear seems a more logical option.

Another possibility is the brakes

That was my thought, until the bearing came up a few times. Guessing at this point I'll just have to do some disassembly unless there's some differential diagnosis I can do without digging in.

Well, it got interesting. Had time and ambition and went after my noise. It was squeaking pushing it around the garage, put it on the lift and started disassembly. I got the swing arm off, stuck my finger in the bearing and rotated it and, well, it felt pretty good. Rotating the wheel no longer produced noise either. I started to pull the wheel, when I noticed some abrasion on the speed ring. Also noted the area abraded was slightly off the wheel surface. I tapped it lightly with a hammer and it seemed to sit better. Is it possible just hitting the sensor was creating the noise and resistance? I couldn't think of anything else to do at the moment, so decided to put it together again. No noise for now. Going to ride it for a bit and see if the noise shows up again. So either it's a simple fix, or things are going to get complicated.

One other thing I've noticed after a recent belt and roller replacement, is occasional high-pitched metallic clatter from the left side which sounds like rollers to me. I think that's supposed to be normal, but I'd never had it before.

Heard from the local Vespa shop yesterday, Moto Richmond, in Richmond, VA. Problem was diagnosed as a slightly warped rotor. Shop is waiting to hear back from Piaggio to see if they will cover the repair under warranty. Bike was purchased new in June 2021.

Fingers crossed they will. It's not exactly an expensive repair in either labour or parts, so even for the sake of good will they should do it FOC.

Well, Vespa covered the brake rotor replacement under warranty, so no cost to me. However, in the process of fixing my bike, they damaged the front end. Evidently, my bike somehow hit the corner of their lift. They are taking care of the damage, but I'll be out of a bike for a month or so. Unbelievable…

Thank you for the condolences…..lol. Fortunately, I've got my wife's white 300 Super and my Honda Navi as backups while mine is in the shop.

Ouch, sucks, glad they are stepping up and hope they fix it properly. Moto Richmond is my dealer as well.

It's not easy to keep a 2 wheeled egg unblemished.

When this happened at the auto repair shops I worked at, we would apologize profusely, give the customer a rental car and put their repair to the front of the line but I'd guess there is a lot more money (and competition) in late model auto collision repairs.

Also I'd ask for the light, side moulding, touch up paint and a service voucher in lieu of body and paint work.
I'd bet they will be tempted to short cut the R&I and continuous clear coat, we used to call them butch blends.
Fender and all trim in front really needs removal for a good job.
Check for dry paint and or paint line at fender indent on body.

I think I'm gonna let them do the repair. I hear what you're saying about shoddy work, but I'm still relatively new to RVA and don't have any idea what other shop in the area would be able/willing to do the work. Hopefully, they'll do a nice job on it. If not, I'll deal with it then.
