Vibration between 70 and 80 MPH?

Ask your mechanic to show you this document: "ROADSTER Belt Vibration_000030176_TST61Y014S05_en"

Sometimes; you can play with the belt tension a bit to tune it to where you normally don't spend much time riding...:thumbup:

ours was vibrating at 80 mph up.. just turned 4000 on 2015 RT
.. Had it down to install trailer hitch. I left the rear wheel off the ground and set belt to 3/4 twist. sat it on the ground and it was closer to 5/8 twist. Took it out and ran it up to 90 mph.. no vibration at any time.. under load or even under power in to high a gear.. I checked the belt travel is about 1 1/4 at mid point.. It is definately a lot looser than when it came from the dealer.. We have not had it 2up yet.. but will and if any noticable difference, I will report..A comment like it is what it is, is not an answer..

Mine vibrates at 74 but not at 73. I'll speed up next time and see if it goes away.

looser tension no vibration

Well all went well. No vibration at all. Not sure if any damage will occur with lack of tension. but if the vibration goes away I'm in with both feet.. Good luck out there getting your dealers to get it right at some point in your ownership..

Vibes...

Yep, it still could be. I never put a tentioner on the 11. I just dealt with it. I just making sure its not something specific on my bike. Of course any time you bring it in for vibs, your gonna get "that's normal". Of course it could be weight related as well, im a big boy. Not saying that it is causing the issue, but it could make it more pronounced.

Mine was driving me nuts from about 65 to 72. Smooth SPYDER belt tensioner stopped it.

Smooth SPYDER belt tensioner stopped it.

The word on the street is that his new model Smooth Spyder tensioner is now available.

I rode some Saturday in the 72-77 range, and experienced some vibration that kind of rolled on/off, kind of like it was resonating if that makes sense.

I noticed my rear wheel has 12 lead balancing weights, which really seems like a lot to me. The wheel or the Kenda must be really out of balance.

Vibration at 70 + MPH

I use to feel a vibration at 70 or higher MPH but I don't feel it anymore. I was told that the belt was new and once it wears down by the grear that the vibration would cease and they must be correct, because I don't feel any vibration and I have ridden it up to 95 MPH.

I don't usually drive that fast but I wanted to check to see if the vibration was truly gone.

vibrations at high speeds

I have the same vibration on mine. It happens at 70MPH and up. I notice it most at cruse and just a bit under power.

I will probably try a belt tensioner. :yes:Farkle

Hi I have had 3 RTs. 12 13 14. They all had vibrations starting around 74 mph. I have a belt tensioner on the 14. It helps but don't cure. I still get the vibs in the 80s. I think there are two issues with the vibrations. When under power, the bottom of the belt vibrates. For that, the tensioner will help. At the higher speeds and the engine "floating" the top of the belt vibrates. It's rather pronounced and annoying riding 2 up pulling a trailer. I'm afraid it's just the nature of the beast. Ron

Picked up my new 2015 rt limited Friday and Sunday had 250 km on it, brought speed up to over 70 mph vibrates a lot under acceleration and letting of throttle brought it up to 100 mph no vibes, went to the dealer this moring tried another one with 10000km almost no vibes, they checked the belt tension and said it was inconsistant in different spots they ordered a new sprocket they think it maybe oval a bit causing different tension as it rolls, they already changed a previous one and said it was fine after, hope it helps

Late to the conversation

2014 RTL,I bought it in July 2015,and felt same vibration. Discussed with two different dealerships and told that the vibration is nature of the beast, part of the 1330 design characteristics.

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

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 have a F3s and I had that problem, then I bought a Smooth Spider and it does not do it any more.

I had the same vibration, I put a smooth spyder on my f3 and no more vibration.
