2007 xt660x front end unstable?
 
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?

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

Thanks All!
 
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. http://www.xt660.com/images/icons/icon14.gif

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 http://www.xt660.com/images/icons/icon14.gif
