XCA weave at hi speed.
« on: November 15, 2019, 01:10:38 PM »
1200 xca 2019 . The bike starts to weave at 180 km/h, it is new. There is 900 km on the clock. If I adjust suspension to sport it is better but not gone. Any ideas?. With and without luggage the same, tire pressure correct.

Blame the big touring screen.

I noticed a speed induced weave on the bike when I changed from non-knobbies to knobbies the first time I ever did that. At past 85 mph (which is ~140 kph) I'd notice it. It got worse around 100 mph.

I'd suspect the tyres / spokes. At that speed, every inaccuracy will cause a wobble. I'm guessing you already lowered the screen and hugging the bike and you don't have the top case on. If you have the top case on, that's a major parasite drag source - the faster you go, the worse it becomes, especially if you have a boxy shaped one.

Do you have a top-box mounted?
If so, try again whitout the top-box and I expect it to be better/start wobbling a bit later....

I took the screen off and got it up to 205kmh. It was better but still not right, maybe I will find a summer screen and keep it under 200. It was properly not designed for high speed. thanks for the help

 I have taken all the luggage off, the same problem. Think of getting a steering damper.

Not sure that a steering damper would do anything for a weave?

I agree with Icy, make sure the spokes are all the same tightness and have not pulled the wheels out of true.
