Weaving (XTZ) - .: XT660.com

I think weaving is the correct term for what I'm experiencing. At moderate to high speed, especially during acceleration combined with quick lane shifts, the whole bike starts swaying heavily. It has never gotten critical just a bit spooky, but since it appears irregular it's hard to replicate and test changes. I just wonder what I should work on to minimize the problem, I have a feeling the tires have a lot to do with it since when I ran on the Karoo/MT21 combo the problem was a lot bigger but on the Tourances it was much less (running on TKC's now). Should I put higher or lower pressure in them? Use harder/softer suspension? Can bad alignment of the wheels affect it?

Its the TCK80s.....mine did exactly the same as soon as I changed the tyres. And yes it is called weaving.
Mine starts at about 100-110 KPH (60-70 mph.)
To stop it I completely release my grip on the bars and just touch the throttle very gently. Scary but it works. I had the same problem on my Pan European ST1300.
Lets face it the TCK80s are not designed to go fast they are a semi off road tyre after all.
Try it....OGR

Ok thanks for the tip. I usually just straighten the bike up and give it a little more gas, sometimes it works sometimes it get worse.

YIP,

I agree with OGR, I run Michelin Endur Comp III & IV's on the TTR - it weaves like crazy at anything over 60mph. I just slow down!

OK, without sounding like I'm after a free set of TKC for my bike (although that would be nice Continental, having bought seven of them in the last six months x) I'm not sure it's necessarily the tyres, as I've not experienced any weaving with them myself...

I run them at 30psi and they are pretty damn good. You might want to check your rear wheel alignment, and also the wheel bearings, just to eliminate those from the equation?

(ps. 140 rear this time please Conti x)

I see, run mine at 2.3 bar (guess it's something like 32 psi?) at the moment since I thought stiffer tires might help. Gonna have someone to look at my bearings just in case. And the alignment, last time the tire was off I held the wrench, that usually means trouble.

Hope you get your tires!
