Loud humming/whine from rear?

[bajakirch]

I picked up a 2019 F750GS a couple of weeks ago, mileage around 600.

While riding, I notice a whining sound that seems to be coming from the rear area of the bike. I've noticed it comes on right around 40 mph, then fades as I accelerate. It tends to come back at around highway speeds.

I experienced a similar noise when I would put a new 70/30 Shinko front on my V-Strom in the past -- the front would whine like that for the first couple thousand miles. But the F750 came with the stock Michelin Anakees, with a much less aggressive tread pattern. Granted, the tires are 5+ years old but, as mentioned above, have less than 1k on them.

The bike's still new to me, so I don't know if this is just a thing with this model/tire, or if it's something I should dig further into.

I suppose you could check your chain alignment and wheel bearings, but I'd vote that it's tire noise with that low of mileage.

It is the tires. I’ve owned several 750/850GS models and they all made noise when new. Takes a couple thousand miles to have it fade away. Mine would quiet down above 4,000 RPM.

You may want to verify the chain is not dry or too tight.

Chain and wheel bearings are good -- I'll chalk it up to the low miles on the tires and wait it out.

Already nearly doubled the mileage on the bike...such an upgrade from my Strom!

My 2022 750 GS had the rear whine until ~ 2000 miles

I would bet on the tires as well. I had Anakees on an R1200GS that were noticeably louder than the tires they replaced.
