Hi All,

Just bought a 2007 xt660x having not ridden on the roads in
a few years , was actually sport bike racing (not a very
successful career).
ANywho my question is that at say 70-80 mph I'm finding
a small wobble in the front end.

Checked wheel balancing, checked head stock bearing.


Could it be due to the high mudguard catching wind or do I need
to get a windshield.

Or is it something else?

Hows your tyre presure im running 30 psi front and rear up to 85 90mph all the time no issuse at all ! Are you maybe hanging on a bit tight try to relax a bit.
Cheers BEAR.

Thanks Bear,

I'll never thought to check the pressures, DOH

Hi there. I also have a 2007 model no isues at 80-85mph myself presures 30-30 psi.

Think I found the problem, only have the bike week, my friend pointed out that I have a dunlop front tyre and a Bridgestone rear, this (I spose) would throw off the balance and create a wobble. Failing that I might buy a small windscreen.

Gee great forum, thanks for the advice, the xt660x is the best fun I've had with my clothes on.

What you trying to say?

Hi m8, did your tyre theory fix it?

I�ve had my XT660x now for a couple of years and love it to bits.

The reason I�m posting is the same reason why I joined this forum in
The 1st place 2 years ago

Can�t remember my exact words but I had, and still have, the same
Problems as you (around 75 plus a worrying weave)

I tried all the usual things, tyres and pressures, shock/fork adjustments
And still had the same weave. I�m not saying that these adjustments are
Not important because they are.

Someone on this forum mentioned �rider position?�
I found that sitting further back on the seat the weave disappeared.

My m8 weighs around 15 stone and can sit anywhere on the seat and
The bike doesn�t weave at any speed.

I�m a shorty and weigh 10 stone. I�ve come to the conclusion that its
A weight come seat position thing due to the xt�x smaller front wheel than the
�R� version. I�ve ridden the �R� with no issues.

Hopes this helps anyone out there who is a bit disillusioned�
It�s a great bike, either sit a bit further back on the seat at higher speeds
Or start eating the pies!!

Hi i only weight 10 stone and mine is rock solid at all speeds ,i ride quite hard i have my fork legs dropped 10mm and 15 w in forks, i also know some very good riders who report the same problem you speak of and others like me have no problem so its a tough one to sort after all the normal checks,all the best

Kev good point i like yourself have an angle on my elbow joint so i push into handlebars and not pull on them,hope that makes sense
