Pitch of tire noise changes in a turn

[motozeke]

Hi all, wonder if anyone else has experienced this: started a trip along Highway 1 north of San Francisco. Shortly into the trip I began to notice a change in pitch of the sound coming from the front tire noise when the bike was leaned over into a turn (a nice feature of a bike with great wind protection and a quiet motor--you notice more!). Even though handling was normal, I pulled over to check the inflation pressure. Came up 43, which sounds about right since I inflate to 40 cold and air temp was about 60. Not that this is science, but it definitely wasn't under inflated which is what I was worried about.

I just installed the Madstad which cut a lot of noise and may be in fact channelling more front end noises up to me through the screen versus my old Cee Bailey.

Bike had 6000 miles and stock tires, running about 50% freeway miles vs. backroad miles.

Anyways, just wanted to see if anybody else had a similar observation.

I have heard this with other makes of tires...not with the stones...the lower the thread the more noise???

Welcome to Chassis Whine caused by tire ware. You did nothing wrong. It has occured on all GL1800 with motorcycle tires. I do not have whine as I am not using a MC tire on the rear.

Mine sounds like that when in turns, I never gave it much thought.
It Never felt weird so I just chalked it to normal sounds

Common on GWs with tire wear. I could hear the tire whine on my '12 GL1800 with the stock windshield. With the MadStad being so quite, you may heard more noises.

That's normal. Some (worn/cupped) tires make more noise than others when leaned over. (I've heard the most complaints about E-3's)

A CT on a MC?!?! That's just plain Abby-Normal!!!

the tire recommends 38 lbs in the front
i followed the recommended pressures and got 19 k out of the front
ran the same stretch of hiway,and yes there is some difference but not enough you should worry,btw if you rode a harley before welcome to the quiet life of f6b ownership!!

Thanks man, guys here report getting better than that by running 40 lbs. And I rode a Ducati Multistrada before this bike... between the wind noise and the exhaust rattle my ears would ring even with a full face helmet and earplugs. Life is so much better now...

Well you learn something new every day! That gives me some peace of mind, as long as I know what it is it won't bother me.

I have a bit of tone difference when I turn. Same as on my VT1100t with E3's so i am not worried. I do 41 psi front and back per dealer recommendation. I ran the same psi on the E3's and got decent mileage.
