Vibration in handles

[Bigmo]

Yesterday, I did about 400 miles with some friends of mine. I noticed a feint vibration on the handles when I reach about 71 MPH. It stays there until 76 MPH than goes away. It was not the road condition. Did that on any road even perfectly paved highway. The vehicle did not pull either way, just straight. Checked the tire pressure and all have the correct pressure. The bike is about 2 weeks old. So basically, it does that at a specific speed. Should I be concerned? I m due for the first service next week.

That is a harmonic vibration coming from the drive-belt...
Contact Doc Humphreys, and he can cure it for you!

That is a typical symptom of a belt vibrating. We have a pretty neat fix for that and it happens to be on sale. Here is a link for the RT:

You probably should not be too concerned......unless it bothers you enough that you "can't live with it".....because it probably is caused by drive belt vibration, which is pretty common.

You definitely should mention it at your service appointment because it could be something else or the tension on the belt might not be right.

If it persists after that, there are idler/tensioner kits available from a couple of sources to "fix" the problem.
Several threads about that exist on here.
I would think that a search for "belt" or "vibration" would find them.

I will bring it up to the dealer but it's a shame that we have to spend more money for an after market kit to correct something that BRP should have done before putting those bikes out.

There's nothing to 'correct'. It's normal for a belt drive and doesn't affect the performance any.

You should be aware that the dealer will want to install the OEM vibration damper, which is not as good as the aftermarket ones.

Doc's dual-bearing setup is vastly superior!

I don't remember where I got them but I bought weights that go on the handle bar tips that is supposed to help with the vibration.

That is a perfectly normal and harmless harmonic vibration from the drive belt. Nothing to be concerned about.

I had a similar problem with my F3LTD. I then found that my front tyres each had a "flat spot" of up to 3mm, which made the not evenly "round". I replaced the Kendas with car tyres, and problem solved. Running as smooth as.
