Whirring Sound at 3800 rpm in 6th

[rummy63]

I am not sure why but I have a whirring sound only when I am riding in 6th gear at about 3800 rpm on my 2007 K1200GT. I just had a new Michelin Road Pilot 3 installed on the front. I have kept the Michelin Road Pilot 2 on the rear until next Spring. It is not an engine or suspension issue. Oddly, the bike performs admirably at any other speed. The sound is annoying and unsettling. Any ideas?

I have the same year m/c as you and the same tire combination. I get a front tire howl at 80 - 100kph.

The Vancouver BMW Motorrad said it is the sypes (sp?) or rain slits that cause the whirring sound and it is normal. Had I known about the whirring sound of the Road Pilot 3's, I would have stayed with the Road Pilot 2's. Going for a ride, bring your best ear plugs.

Happened to replace RP2 on back so I had RP3 on front and back. Problem gone.

I have the pilot road 3's on a K1300S and don't notice any noise... got amazing life out of them, 12,500 miles on the last pair

Sounds like the clutch as mine does the same thing. It has a gear whine in sixth gear. From what I understand the clutch basket gets grooves wore in it and that causes the noise. I have PR3's front and rear and they have a little noise to them depending on the road surface I am on but not to the extent of a whining noise.
