:eek: Went for a little ride today on my 06 4700 and I heard a high pitched whine that was coming from the rear end of the bike. I noticed that when I turned or leaned slowed down it got louder I check the final drive oil when I got home and it was OK. Right now I am thinking that it is going to require a trip to the stealer for warranty work. Any ideas what's up and is it some thing that I should be worried about in the first place.

Thanks

Sounds like it could be a bearing gone bad. Now it's just a matter of it making the noise when you take it to the dealer.

Prolly all the extra horsepower from the :eek: 4700cc :eek: motor over the lil ol' 1300. Puts extra stress on the bearings. :cool:

You don't have them crummy DUNFLOP Tires do you. Mine does the same thing and it is the tires. I've had the wheels off twice and the bearings are fine. I could not believe that tires could make that much noise. But they can!!!!!!!!!!!!!!!!! You can even feel the roughness. Feels just like bearings, but it ain't.

Well I do have the dunlop tires but I would of thought that the sound would have been more of a hum. I have called the dealer and they said bring it in and they would check it out. I will let you know what they have to say.

My OEM tires were the Dunlops and I never noticed any whine.

I can't remember who it was but at the last TechSTOC at Turbo Tom's when they pulled it 2 of us heard a loud whine from his bike. He rode it back and forth in the parking lot but the whine was gone. A short time later I learned that he had it in to the dealer and had a bad bearing in the rear wheel.

My 03 with Dunlops started hauling around 5000 miles. First I was convinced it was a bearing but it was in fact the tire. Noise disappeared with new tires. However, it was the front that was hauling, not the rear. And only while leaning or on slanted pavement. Still sounded like a bearing though and wouldn't have been suprised if it had been one!

on my factory dunlops with 6000 miles they are relatively quiet on dead center..go around a little turn and the whine starts. I would go with tire whine before bearings.Geoff

+1, the Dunlops that came on mine just howled when you leaned her over even the slightest bit. For a while I was sure I had some final drive issues. Went away with a change in rubber.

I have just gotten my 05. It has 4100 miles and stock Dunlops.
I was just out and was able to log nearly 200 miles. (first ride of the season and on a new ride. Its so GOOOOOOD) But I have a noticable whine even on small curves. I think sure it's the tire but I think my sound is coming from the front tire.
I hope it's something as easy to fix as tires!!!!!!

:06biker: Well the dealer looked at it and they said that it wasn't any thing wrong and that it was just the tires. After riding today I didn't hear it as bad but I did hear it but yesterday I was riding two up with my sun on the back. So I think that I will have to agree with the tires too. I would have never thought that tires could make that much difference.

And it's still to cool out to be a "whine" about the heat.

I still think a huge part of the reason is because of the overall quietness of the MC. It is so quiet that we hear things we don't on other bikes...

Same here: whine from the Dunlops was much more annoying when riding two up.

It's hard to believe that TIRES can make that much noise, isn't it? I've got a new set of Metzler Z-6's hanging in the rafters in the shop. I really need to stop procrastinating and put them on.

My riding buddy, Ray, bought an '03 in spring '04. He rode it home from Flagstaff, and stopped a couple of times thinking he had a problem. Says it was the first time he ever heard the tires on a MC...and he's been riding 60 years, now:)

When researching ST1300's (before buying recently), I ran into the following website that discusses "issues" including a whine that some ST1300's exhibit:

Hope this helps.

I also have noticed a whine on my 2005 ST, but my conclusion was that the front fender resonates when excited at its natural frequency. If the speed and pavement roughness are just right it can really howl.

Now -- how to cure this? Has anyone added damping material to the fender, or has anyone added rubber biscuits between the fender and the fork legs?

UPDATE: Now running Avon Storms with no whine! Pretty sure the Dunlop 220 OEM tread pattern excites the front fender vibration at certain speeds. This has gone away with the Avons.
