It sounds like you need to check your preload settings. You repeatedly encounter wobbles. You have one preload on front and one on rear. Rule of thumb is sag from rider and bike deadload should be 1/3 of the travel, which I think is 6.9” on the V85.

Manufacturers have test riders whose work is to tune the chassis design and suspension settings to avoid what you’re experiencing.

Something is wrong.

I've done several passes in the mid 90' on my 2021 85tt with Dunlop trailsmart max tires, loaded side cases and large duffel on top. Bike has been rock solid in some pretty harsh side winds. Never any cause for concern.

I forgot, check the spokes as well as the swingarm bearings.

After I lost the front end on my V85 in strong side winds and a wet road, I decided that the Michelin Anakee Adventure tyres were not for me.  Coupled with the fact that I don't ride off-road, and try to avoid gravel roads where possible.

They were replaced with Michelin Road 5 Trail, and the difference was chalk and cheese.

Incidentally, I found the same issue when I purchased and Indian FTR1200S.  It too had off road tyres, I obviously hadn't learnt my lesson.  These were replaced with Battlax Sport Touring T32, again a move I haven't regretted.

Finally to add my $0.02¢ to setting preload.  I agree with Huzo, adjusting preload settings alters the ride height only (for non-progressive springs).  Nothing more.

Would checking the steering head bearings be of any value?

Ride height is an important issue, is related to chassis stability and is affected by preload regardless of if the spring is progressive. The OP could weigh alot and have the max setting on front preload and the min (which he already indicated because he had trouble reaching) on rear. Start in the middle on all the settings or as recommended in the manual….

Then get the front off the ground and shake the fork legs from front to back to check for steering head play. Then check that the front GLIDES smoothly through the steering range. It should require almost no force and no notchy feel. Then  grab the rear tire when off the ground and check for swingarm play. Chassis pivot points should be okay an a bike so new…..

Something is wrong with the setup. It sounds like he may be heavy and has trouble reaching. The bike doesn’t  care. Use the right spring  and preload for the weight

I’ll do it now.

His thread is just muddying the water for him, unless a poster can actually look at his bike and eliminate the conjecture. He needs to figure it out  or have someone do it before he gets killed.

That’s why I started the one about pre load, it was rapidly submerging the intended topic.
However, whatever the root cause ends up to be, extraneous information cannot be a bad thing, as long as you don’t necessarily expect it to contain a solution.

I'm wondering if removing the windshield would have an effect.

I don’t think it would Sarah. From my experience most of the issues being discussed in this thread are rear shock related.

I experienced much the same thing on a V7II while riding to California and back earlier this year.  Pelican-style cases on HB racks and a Dart Marlin shield.  I posted about it along the way and got lots of suggestions, tried everything to some benefit but nothing resolved the issue completely.  If I had it to do over I'd remove that screen just to see.

Reading and writing are having a limited effect. A simple adjustment and/or ruling out steering stem misadjustment would likely resolve…..

Extraneous information is a hindrance to getting a point across, maybe even to reading in the first place.

If there is “a point to get across”, could you share it with us..?

There may be a place for science projects/lessons but this didn't look like it, when the original poster had problems articulating. The diffuse, possibly erroneous nature of ensuing posts, and your separate thread made me feel the need to reply.

Reply by all means, your input is as good as anyone’s.
But that’s why I took the conversation about pre load to another thread, it’s been going on for a few years. Rudy does not have to concern himself with it if he does not want to, indeed I can’t see why he would. But there are people who are interested, have you seen the number of views ?
Now maybe we can get out of Rudy’s thread.

I adjusted the rear mono shock was on lowest setting.  On front fork judgment, is screw & lock nut just for rebound?  My windshield I’m going to adjust the angel. Rudy

The 14MM nut on the fork is preload and the screw is for rebound. I'd start with 1 turn from no preload and the rebound mid way.

I don’t know the cause but I read a tip that made sense as to what to do if this happens.The late Oak,bmw expert,suggests To loosen your grip on the left and centrifugal force will stop the wobble.Apparently the impulse to hang on tight is counterproductive and aggravates the problem.I think you do not abruptly release the throttle but gradually slow until the shaking stops.A very terrifying experience and a professional Guzzi test rider was killed in LA in the 60s trying to solve the problem on police bikes .This happened to him on a race track,I don’t know if they ever figured out th the cause or the fix.I had it happen to me on my Eldo back in 79 and solved it by removing the handlebar Wixom fairing.

I had check the tire pressure the next day after I had the wable.  But not since then.  I have had a wable at the speed I was going, but it was not bad as I had this( test riding a KLR at sturgis)time.  And had bad wable at lower speed but not like the one I had on the V85.  I’m going to run slower on freeways.  And stay on more gravel mt. roads exploring and camping,and mt. fishing.  No camping next week taking my wife on a cruise ( going to the front line’s so to speak on the --19 war).Rudy

Start by slowing down.  Go from there.

I’m forced to ride the slab living in the northeast. NEVER have I had to do 90+ to pass anything.

Oh, man- I-55 south out of Chicago is just crazy fast.  I was doing 90 on my Ducati and was passed like I was standing still.  Now, to be honest, there is no reason to drive slow in that landscape (no offense to anyone living there).
