Usually the "driven" tire that cups...number of variables that cause this, mostly on OEM Dunlops...

Spirited mountain riding for me cups both tires. Ride it like you stole it. But yes the OEM Dunlops are known to make noise in turns. I went with Commander 2s and never heard it again, different tread profile.

I am likely all wet on this one (usually am) but a tech told me that the whine heard in a Milwaukee 8 is the gearing that drives the counter-balance shaft. He said they are straight cut rather than helical so they will sing. In my M-8 the sing is most noticeable at about 2200 rpms in 3rd gear and no acceleration (30-35 mph around town).

I actually like the whine. With the heavy lope of my RS468, and the loud exhaust, I think it all sounds cool.

Same here. My 2018 RGU makes a lot of noises, and I love all of them.

Completely stock. 33k miles. Mostly two-up riding. All weather. This bike has no weaknesses that I can find. Yet.

Then never take your bike to the dealership because (forgive me) "it's normal" for dealerships to respond that way, "they all do that."

Harleys don't exactly have the tolerances of a Rolex - expect and embrace the noises.

This ^^^ I run synthetic GEAR oil in my GEAR box. I don't run Syn3 in anything but I have never heard of a problem with anyone running synthetic gear oil (or even dino gear oil for that matter) in a H-D transmission.

I guess, come to think of it, that's not a good answer.. Overall it has to do with manufacturing tolerances. HDs can be noisey mechanically.

Again, the H-D MoCo has what you could say is a big tolerance for big tolerances; if you're running a H-D motorcycle, you should as well.

The factory rep will say, "That's normal; they all do that."

Their warranty ratios matter but they also don not make much money on warranty work because the shop rate is nowhere near what we pay.

Like I said, these things ain't no Honda - but I don't own a Honda motorcycle; I own a Harley!
