I recently noticed my rear wheel gets pretty hot.

As in: when I've gone for a ride, I can put my finger on the rim easily, but if push it on the rim for a couple of seconds, it starts to feel hot. Not skin burning hot, but definitely hotter than what I would call 'warm'.

(I noticed because I painted my exhaust with BBQ paint (as per Scooterwest's idea) and I smelled it (logical: it needs to burn in), but that's why I got close to that area straight after riding, which I previously never did.)


Could anyone tell me from the above description if this is normal for a GTS, or if I should analyse further?

Thanks!

Put it on the center stand and turn the rear wheel by hand.
That should go easily. If that is the case there is no problem.

If it is the wheel bearing you don't need to buy it from the vespa dealer, Your local Dixie Bearing or derivative thereof has them for half the price. Be sure to bring in the old one for an accurate measurement. [/i]

fairly warm is typical, especially after spirited riding or long pulls.

a bearing going bad would more than likely be noisy, but would also be localized more or less to the swing arm.

if you do need a bearing, it's a 6303 (size is 17x47x14)

you'll want a 6303 2RS C3-- the 2RS is double sealed, and the C3 is the clearance spec. they generally run about $15

a _long_ ride will warm it up. it's sandwiched between hot things - engine + exhaust + transmission - with minimal airflow over it.

Thank you all!

When on the center stand it's not noisy and the wheel turns freely.

The brake disc is relatively cool (when only using the front brake). I tried this to make sure it was not a dragging brake caliper.


Since you don't all jump out of your chairs and shouting my tire is going to explode, I feel a bit more at ease now .

Seriously, you should be able to relax. On the bearing issue, I have a hard time seeing how heat from a bad bearing would significantly heat all the way to the rim, but guess it's possible to a degree. Have to inspect my own when I remember, but there's a bunch of friction with the tire that has to warm things up.... Nerd emoticon

No need to worry, indeed.
