Rode about 45 miles - still same problem. I am taking it back and have them figure it out.
I remember. Dyna Bead balancing solved my wobble and completely eliminated the feathering of the tread as the tire wore.
Dynamic bead balancing?
I can't help but wonder if this isn't really an 800XC problem. I have stock Scorpions on my 2013 800XC and I have a very noticeable front end vertical oscillation at 40MPH. I've never encountered anything like that in the half a dozen or so bikes that I have owned.
I seem to recall that some other 800XC owners have mentioned a similar issue with their bike. I was already looking into some suspension upgrades in an attempt to eliminate the oscillation.
It might be good to start another thread and compare stories and potential fixes?
There may be one here? But the tiger 800 uk forum has quite a few that discuss this and a survey. Based on what I am finding this is a frequent problem. Interesting that you have it with the current oem tires. Original oem tire was bridgestones avid I never noticed it until tire replacement. So far I have not seen a standard fix other than some gave reported success with suspension setting adjustment. I have seen no improvement with adjustments to suspension or tire pressure. I am not sure I feel like experimenting with suspension upgrades. I am not enjoying riding it now and am a little discouraged with Triumph at this point. We'll see.
Have they check the balance of the bare wheels? Steering head bearings lubed and tight?
My DL1K will go in to a tank slapper descending from about 40mph down to 20 ONLY if I am hands off (tourance). Hands on, I have never felt it wobble. Even when it does wobble, it doesn't bother me since I can grab the bars and it goes away. This probably doesn't help, but I wonder if the big adv style bikes are just a bit prone to this?
Edit: Crazy thought, but if this only happened after they changed the tires...did they adjust the chain too tight? Most chains I have seen don't show an even amount of slack at various wheel positions. If they got it too tight, I could be jacking on the swingarm?
I loosened the chain to slack end of speck. Wheels are within .5 of spec. Supposedly they are considered in spec by Triumph at 1mm out of round. I am reading of lots of people with this issue. So yes it seems to be endemic to these 21 inch wheels on the Tiger XC but I am seeing mention of the roadie owners with the same problem.
I would consider changing the wheel bearings, even though the bike is basically new. Bad bearings can cause this problem at these speeds. I've had it several times.
If you do replace the bearings, I would try to cross-reference them and buy a set of premium Timken/Fafnir or SKF if that is not what is being used at the factory. Having the stock bearings replaced under warranty with similar cheap bearings (if that is the case) will possibly not fix the issue.
I've encountered premium motorcycle manufacturers using bearings sourced from far-away asian lands that surprised me. Replacing them with good stuff eliminated the sort of wheel wobble we are discussing.
As already mentioned, also check the steering head bearings tension etc.
sometimes a bad rear tire will make the front wobble... just say'n
My last three motorcycles have done that. All very different bikes with different tires.
That's just weird. I've never had a bike with a vertical wobble or oscillation. Even dirt bikes I beat the crap out of.
Have generally found over the years that the tires are more perfect than the rims. Next time you change tires try leaving the existing balancing weights on the rim. Then see if they need rebalancing with the new tire. You'll probably find that the old weight placement isn't that far off. The front wheel of my S10 hasn't taken any weight for 2 tire changes now and is in perfect balance. Tells me the front Anakee 2 last put on was perfectly round and balanced.
Tried 2 Anakee 3s which both balanced to zero both with wobble. Then the TR 91 which required 2 weights - same wobble. New bike under warranty so I am not dicking around with it myself.
Got warranted wheel replaced after required Triumph checklist for fork oil etc. The Dunlop had a visible variance when spun on the jig. New (3rd) Anakee 3 on front and rear that was on before. Bike rides fine now. Might be a slight wobble at 37 mph or so but hardly if anything noticeable. So - who knows what the real story is???
Have you considered front suspenson stiction? Too heavy oil, or too much damping?
I battled this terribly on my V Strom 1000 I just parted company with. Had one hell of a head shake on de-cell at in town speeds, under 35 mph. was going to switch to a different tire but instead got a new bike
Yes looked at everything
My old strom did that too. It was partially cured by going to a Battle Wing front, which is an extremely heavy tire.
