Vibration between 70 and 80 MPH?

[Bobfour]

vibration

Anyone else feeling a vibe around 70 to 80? Sometimes its lower 70s, sometime upper 70s to 80. It goes away with a little more speed. Feels different from the vibration I had on the 2011. Feels more like its coming from the engine. I will try to see what RPM it is when its doing it. Hopefully I can ride it this afternoon and tomorrow. Just seeing if anyone else is noticing it.

I had the same vibration, then I installed a smooth spider on my 15 and it is gone.

Try riding at 69 MPH or 81 MPH
problem solved and, it's free

I like your solution! :thumbup:

LOOSE SETTING

Hi,
sounds like you changed the wave length of the belt. And in doing so might have canceled out the initial vibration. Like you added an extra wave. Something like the DOLBY noise canceling headphones. You might have found the answer that folks have been putting up with for years.ray: The boys back at CAN AM might be interested in your findings. I know I am. Good Luck,
Ron

:agree:....With Schnauzer, I also run a loose belt and don't notice any vibes from belt.......I also don't worry about the Shaft bearings seizing either :roflblack::roflblack::roflblack:........Mike :thumbup:

I can't explain the possible reasons why, but my 2015 F3-S has a vibration at certain RPM, not MPH...between 3700-4000 RPM. Above 4000, it suddenly disappears. So far, the ride enjoyment overshadows the vibration!

vibration

I was getting a vibration above 70 mph and adjusting the belt fixed that... BUT I have another vibration that is worse, and is RPM related.... does it in 4th , 5th and 6th gears between 3450 and 3900 RPM... I would not think this is belt related because it happens at 3 different belt speeds....
The bike feels and sounds like it is running over rumble strips at those RPM....

I never felt vibrations on my 2008 GS SM5 or my 2011 RT-S SE5 with the 990 Rotax, but yesterday when out riding my 2015 F3-S SM6 with the 1330, I noticed a vibration between about 68 and 72 mph in 6th gear, and at a slightly slower speed in 5th gear, but not quite as noticeable. Once I got it up over 73 to 75 mph, it went away. Kind of annoying. I think it's more RPM related, not MPH related. Just seemed worse in 6th gear.

Should I be getting my belt tension checked? I have just over 1,200 miles on it.

rock the throttle and move past the vibration. Not rocket science.

Tricky to do when riding with a group and the speed limit is 70 mph. I was running sweep yesterday on the freeway and kept hitting the vibration zone. To roll through it meant I was going too fast to match pace with the group. A bit annoying.

Humm not sure, takes less then 1/2 second for me.

I got it to go away, but it kept coming back.

I had the same vibration in the 65+ to the 75ish range. I installed the SmoothSyder belt tensioner and I have very little vibration now. It worked for me. Why, I don't know, but it did! :thumbup: (2015 F3-S SE6)

 

[MOSESS]

Do it

Put a smooth tensioner on it and problem solved .I had to do it because it was driving me crazy .Its upsetting that BRP would sell a product that had an issue of this magnitude .

vibration

I find it interesting that the vibration is blamed on the belt--especially since I can get same vibration while parked by just revving the engine in the mid 3K to 4K rpm range. I will admit that the belt tension roller does reduce part of the vibration but I believe the tension rollers just remove part of the vibration caused by the engine. A looser belt also provides a lower conduction path to the rider.

Never have experienced vibrations on my 2014 RT sm6. But I never go over 65 mph, most of the time 55-58. I've always been that way. I just like to Cruise. A great day for me is all back roads and 35-45 mph all day. And because I'm so lite on the throttle, my last 5 tanks netted me 41.2 mpg on 91 octane, ethonol free.

I have the exact same thing. Was told it was harmonic but feels like the Spyker is vibrating apart. Have to get out of that rpm range.
Going into the shop and asking to look into it again.

Did you ever get it fixed.

I had the same vibration, put on a smooth spider and the vibration is gone on my 2016 F3T.

 

[Msmoto]

Thanks, I have it as well

My new (two days ago) 2016 F3 Limited SS has this about 70 - 75 mph, seems more when backed off. Nice to know that it is apparently a normal phenomenon, but will check out an anti vibration device as it is annoying.

BRP is coming out with a belt tensioner for the f3s... :thumbup:

But we need one for the RT also.
