Vibration at 67-75 MPH on F3-S

[vondalyn]

it's the long belt. it's totally in your control to speed up or slow down so that you're not driving in the vibration zone.

We should not have to drive out of the vibration. BRP needs to fix this, our bikes aren't some cheap China made bikes, we all payed over 20k for our bikes so there is no excuse for this.:banghead:

Dealer responseee

Hi,

Has anyone taken their F3 in to the dealer and had them address this issue, if so what was their reply. I am due to take delivery on my F3S in a couple weeks and this has me concerned.

Any chance you are purchasing bike in Mineola?

No chance.. The dealers on LI suck ! I went to CT

Has anyone noticed a vibration when you roll on the throttle at 67-75..worst mostly at 69ish-71? It is a pretty strong grinding feeling.

Definitely feel the vibration when accelerating from 67 mph to 72 mph. Have a little over 1,200 miles on the bike and it's had this vibration from the beginning. Almost feels like running over small speed bumps?

Dropping the F3s at the dealers next Friday to install heated grips and some driving lights, I'll have them check it out while it's there.

If they have anything to fix this minor problem, I'll post a report.

Seems to me like this machine could benefit from a belt tension/idler roller of some sort?

Lets count, how many people having a vibration problem,

Vibes

Has anyone noticed a vibration when you roll on the throttle at 67-75..worst mostly at 69ish-71? It is a pretty strong grinding feeling.

I have a tensioner in the works for the F3, along with a backrest.
I took the demo from my dealer for a 35 mile ride and the vibration was quite pronounced, my wife even noticed.
My demo was set in Kilometers and it was around 123-125 which converted to 76-77 MPH.
My magnesium SM should be here any day, I can hardly wait!
My LG headset that I had worn around my neck for a year blew off and got ran over in the first mile, I haven't even taken delivery and it's already costing me. It was worth it though.

I have pronounced vibrations in 6th gear at 3000 RPM AND ABOVE, makes freeway riding unpleasant. I am on the waiting list for Capt. Jim's belt tensioner Also BRP says they are looking for a fix. BRP Says belt tension should be set at 750N,+\~150N

yep exact speed only on acceleration, im with ya

Hi,
i have an f3 that his is as slick, powerful and smooth,as you'd expect from that kcaliber of machine, right up to 67-75,af which point it becomes as a machine with worn out ball bearings and square wheels !

On my first ride(s) with the F3 this weekend, 160m & 170m days, I did notice a vibration at just about
3800-3900 RPM. I'll have to check it again this coming weekend and compare the RPMs, sound, and play
in 5th and 6th. (It sounds more like engine harmonics to me and not in the driveline/belt...etc)

Drove my new F3 home from Spyderfest. Now have about 800 miles on the bike. Belt has loosened a bit with break in and the vibration point has come down the scale. When new it was at about 73 or 74. Now its in the 71, 72 range. But it is significantly more belt vibration that what my 13 RT had before the smoothspyder tensioner. I also note that my belt is riding right against the flange on the rear sprocket but its not enough to leave black marks or wear the belt edge, my RT did the same for 8500 miles.

I look forward to a solution for this. A small annoyance on an otherwise fabulous bike.

Harmonic

It's not a problem with manufacturing... It's just a harmonic vibration from the belt. Pretty much inevitable with any belt drive setup.

Still not acceptable and degrading the enjoyment of a beautiful machine,

100% agree. Especially being in the sweet-spot for highway cruising. (We need someone with a dyno
rack to run it on and observe for some better analysis)

Same here...

Has anyone noticed a vibration when you roll on the throttle at 67-75..worst mostly at 69ish-71? It is a pretty strong grinding feeling.

Yup....I have had my since April 4th and noticed the vibration beyond 65+. Left side and it seems to be getting worse. But I have noticed that it does not grind when using the cruise control. I have 600 miles on her now and I'm taking her in for her first service this weekend and to get all the accessories I ordered put on her. I will be sure and inform them of this vibration. Feed back coming....

First service is not until 3000 miles. Still a good time to install accessories and get the vibration on record.

Most Triples have a vibration problem

Talked to a knowledgeable biker who stated that most Triples vibrate around 4000 rpm, and that the vibration magnifies along the belt.

Did a quick google on "vibration and triples" and noted issues with Triumph, BMW, Yamaha, and the Harley-Davidson XL 1200"s.

My solution is to increase or decrease speed or change gears (SM6) - 4000 rpm - 68 mph in 6th gear; downshift into 5th gear - 5000 rpm. The same applies at lower speeds and gears.

Hopefully a better solution in belt adjustments will be found.

I also, get that vibration at 65+. Since I have the Garmin tire pressure sensors installed, I have been able to "watch" speed to pressure. Keeping the pressure as close to recommended "during the ride" has removed some of that. I do know for a fact that at 104mph, no vibration with front tires at 15.2psi.

 

[kaamacat]

With the belt tension unit offered... thought here... you figure that the unit will stop
some of the vibration/movement but not all, and, you do not want to over-tension the
belt. What-if the unit was mounted similar to an engine or transmission mount (isolator)
so the remaining vibrations travel through rubber vs steel/aluminum?

No different than if you took engine mounts in a car and went urethane or solids. There
is a huge difference just going rubber to urethane in what is transmitted. And with this
somewhere along the line you still have metal-on-metal. (THOUGHTS?)

:agree: This is spot on with my experience as well - yesterday I just happened to downshift into 5th gear when vibration started (67-68 mph in 6th gear ) and vibration was significantly reduced.
