yup tire tread, you probably dont notice it on right hand sweepers just because IDK about you but I tend to lean a little farther on the left side.

 

Yep. I have it as well. I was just as worried as you, but alas, Dunlops.

 

==================

Tire cupping and or bad wheel bearing would be most likely cause.

BTW,many things can go bad at low miles,compsensator was completely shot on my 09 at only 9,700 miles .

If it turns out to be a tire cupping issue remove the wheel wts and install proper max amount of of ride-on rec for your front tire size into the front tire which will properly balance it.

But the reason i rec here is mostloy because even thought its not mentioned by mfg installing ride on in a bike tire that noisy/humming/moaning when cornering because the material the ride-on is made of dampens the tire noise .

I found this out 1st hand on my last bike that did the same thing your was doing that when i installed the ride-on to better balance the front tire & protect it from punctures it actually stopped all the moaning/howling when cornering.

So if your tire has a lot of life left in it then it would be worth doing if you find wheel bearing to be ok

My 888's have a harder compound down the center for longevity and a softer compound on the sides for better handling. I wonder if that's the reason that the cornering hum is the loudest of any tire I've ever run since the day I installed it?

 

Just the tires, kick it up a notch and let the Big Dog eat!

 

I always thought it was the teeth on the belt connecting with the rear pulley. Figured it was more apparent on left hand sweeps because the rear pulley is closer to the ground.

 

Not just tread pattern but also a symptom of cupping. Tires seem to cup earlier if run the least bit low on air. How often do you check your pressure?

 

just your dunlops growling...all mine do it.

 

Me too! I know it is not the wheel bearing, easy to check. I know it is not the tires as I scrape my Jackpots and that is about as far as the kick stand allows on the left side. I always figured it was the rear hub and belt sound reflected back to me.

 

Interesting thought, but would you not hear that hum all the time if that was the case.

I check my tire pressure about every 2nd time out or if the bike has sat for a couple of days.
