Hello all,

Just did a 300+ mile trip and noticed while on the interstate that I'm getting a lot of front end vibration starting around 75+MPH in 6th gear @ roughly 3000RPM. No idea if it continues into the upper speeds because I'm too nervous to bring it that high in fear of it getting worse. It's not uncontrollable but the image in the rear views definitely gets blurry. I can feel it in the floor boards as well. Once I get below 70 MPH it stops and is as smooth as glass. It stays smooth from idle up to the before mentioned speed. I know it isn't RPM related due to the fact that at 3000RPM in 5th gear it remains very smooth. Any help would be greatly appreciated! I'm just trying to get a good starting point where to look to see what the issue could be. Thank you very much for yall's time!

Since it's a '17 model............

If it were my bike I'd take it back to the dealer and let them trouble shoot it. It really could be multiple things, a tire slightly out of balance, a defective tire that rears it's problem at higher rotational speeds, a bearing issue etc.

Really hard to tell. Has it always done it or is this a recent development?

Its a recent development, when i first bought it it was smooth as can be. This last trip was the first i noticed it, i'll be bringing it back to the dealer and see what they say. Thankfully its under warranty. Thanks for the response, i really do appreciate it

I have a 17 RGS and have the same issue. I only have 1600 miles on mine. I also feel it slightly in the floor boards. At first smooth all the way to 80 MPH. I just don't ride faster than that. Now vibrates at 70. Too much vibration to ride 70 MPH or above. Under 70 MPH still pretty smooth. Left it at the dealer yesterday (Sunday). Service will look at it tomorrow (Tuesday). I'll update when I get it back.

Cponline, turns out after many many miles of troubleshooting the front tire was bad. It must have been getting out of round above a certain speed. I ended up replacing both tires with Michelin commanders 2s and it made a worlds difference. Hopefully you have a simpler fix like just a good rebalance

Did you change the windshield? That can effect the aerodynamics & cause vibration.

I do have a 10" LRS, but noticed it with OEM windshield, too. Front end starts to get busy over 65 and scary at 70. Dealer can't get to it until Tuesday.

As others have mentioned - I would take it to the dealership. Also, what size windshield and were the vents opened or closed? It does make a difference.

Didn't check the vents. I always leave them open, but I could have closed one when wiping the dust off the fairing. I'd be OK if that's all it is. I have 3 windshields. OEM, 11" LRS and 10" LRS. Too much buffeting with OEM. Got 11" LRS. Like it, but not being able to touch the ground flat footed got annoying. Lowered the seat about 1 1/2. Needed shorter windshield so ordered the 10" LRS. While waiting for 10" put on OEM. After a couple of rides with OEM back on noticed front end shaking up and down at 70. For reference the vent/ fairing oscillates/ flutters up and down about 1/4 inch. Feel it in the bars and a bit in the floor boards. Put on new 10" LRS. Same symptoms.

I'm not a betting man, but if forced to I'd bet a broken belt in the tire. PS. Bike is stored on my J&S Jack Stand if it sits more than a week so doubt if its a flat spot from storage.

It's at the dealer. We're have some OK weather so I'm itching to get it back.

Got my RGS back from dealer today. They found the front end swing away out of tolerance. Adjusted and much better. Now 70 MPH is no problem, but 80 MPH is still a bit too busy. At 80 MPH the gauges become blurry. Dealer checked tire, balance, air pressure and all looked good. I'm still searching. If I can get it calmed down at 80 MPH I'll call it good. Dealer said it might be the bearing, if it gets bad at 70 MPH again he would suspect a bad steering head bearing and it would be covered under warranty.

Some good news about this experience. I took it to the dealer closest to me, Destination Harley in Tacoma, WA. I didn't buy the bike from them (I wanted Superior Blue and they didn't have one) nor did they do the 1000 mile. But listen to this, they did the check and adjustment for free. I have bought lots of parts from them for my previous bike so as a courtesy they waved the labor charge.

Been out of town for two weeks so haven't had time to fully explore the "fix". It's better, but not perfect. While on vacation I rented a RGU. It was smooth as silk to over 80 MPH. No vibration what so ever and the road I tested it on was chip sealed asphalt. All I felt was the poor condition of the road, but no real vibration in the fairing nor the handlebars. Wish mine was as stable. I think I need a second opinion.
