There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

vibration
It is vibration cause by the rear wheel drive belt. You will usually feel the belt vibrating in the 55-75 MPH range depending on your bike, how tight the belt is and various factors. For most people it happens within about a 5 or 10 MPH range somewhere between 55-75. People say they feel it when the bike is under a load as in going up hills and others say they feel it going down hills while others say all the time,SO, it can basically happen any time I suppose.
I have bought several vibration dampeners and none of them worked until I bought the vibration dampener from Roadster Renovations and it has work GREAT. It is a simple design that is easy to install and is cheaper than the others but the best part of it all is that it WORKS. They are a sponsor here on the home page. Give Doc and Kathy Humphreys a call and you will love the service you get.:clap:

Not sure if you know or not but there is a spyder riding club down there called "spyders on the gulf " they have a facebook page. I live in ellisville, just above hattiesburg
Another :2thumbs: for Doc's device. Even if you are new to Spyders you will recognize the issue if you have it. Sometimes a bit of adjustment in belt tension will cure it. I had my belt everywhere from way to tight to ready to fall off and couldn't get the vibration to a reasonable level. All it did was move it around to different speeds. Doc's vibration damper did the trick for me.

One test you might try is to downshift one gear while still maintaining that speed. If it still vibrates, it's the belt. If it doesn't it might be a tire balance issue. Lamonster sells some balancers for the front wheel that might help.

I don't know which trike you have but I'm guessing they are all different as far as where on the speed scale they vibrate (the worst). My vibration is the least and almost non existent when the belt tension is at or near the lowest recommend setting. That setting for me is 200/220 lbs. on the cricket belt adjustment gage, with the tire on the ground. Good luck. Go with Doc and install his dampener and it'll help a bunch. One would think that BRP would not turn their bikes loose on the public until the vibration issue had been resolved. What a bunch of turkeys.

Just an FYI, Can Am just came out with one of their own. It is P/N 219800419 and it is only $39.95.
Mine is being installed this weekend.

The one that can-am came out with is a piece of junk. Doc Humphreys has a box FULL of those that have failed after only a few hundred miles. Not worth wrecking a belt in my opinion.

We pulled this one off in Maggie Valley last year.
Bottom line; If you run their idler make sure they install it so that if it fails and takes out the belt it will be covered under warranty.

Another vote for Doc's damper! :thumbup:
The bearing setup in his, is VASTLY superior to the P.O.S. being sold by BRP. nojoke

BRP Belt Tensioner is junk
The plastic arm holds up, bit the roller does not have the bearings and breaks. Buy the Doc Humphries one.

Dennis, the unique attaching design we use on our rollers is part of the reason we are getting the mileage out of them. That can only be done with our setup. Sorry.
Vibration.
I bought a new 2017 RT-S April 20. Noticed the vibration. The more I rode the more I realized that this was not something one could get used to. I adjusted the alignment of the belt so I was centered on the rear sprocket. Went for a ride and it was better, not perfect but better. I always back into my garage and when I looked at the belt after getting in the garage it was tight to the inside of the rear sprocket again. Adjusted it again and test rode. This time I drove into the garage and the belt was right on the outside edge and still had a vibration. So I adjusted it again and checked Both sprockets and adjusted until it was not touching on any edge of either sprocket, and now it is almost perfect.

As others have mentioned, the time to check belt tracking is after forward motion. for some reason backing up the belt go haywire. so spin it forward motion or drive it forward, then look at it
we noticed this on our new 2016 F3 Limited. right when we are passing through 55 mph and then again at 65 mph.
As severe as this vibration is, I am wondering why BRP does just not fix this as a warranty issue? I saw someone mention that BRP sells a damper for $39.95 (I get that people feel it's junk), but my point is, why would BRP charge anything at all to get rid of what is obviously not an as designed behavior? (at least I hope it was not designed in as a "feature" !)
I am having my dealer install Baja Ron's ASB next week and I am going to ask about this.
I understand that the dampener sold by RR works great, but my concern is putting anything, regardless of how simple a device it might be, anywhere in the drive system on a brand new Spyder and what warranty problems could result down the road if something happens and BRP blames it on an aftermarket item, even though it would likely have nothing to do with it. We all know how vehicle manufacturers operate. Trust me, I am not saying it's not a great device, as it obviously is from what everyone is saying. But I am not a wrench, and it just seems to me that BRP should be responsible for fixing this issue. Perhaps I am being naive, and I accept that.
I've just never bought a brand new vehicle where a serious performance problem (and I consider the vibration we are feeling through the rear end, frame and footboards a serious performance problem) was not rectified by the manufacturer.
