If you mean a slight wobble during hard braking: no, that's your tyre.
My Enduro4 also shows this behaviour when it is brand new. It will go away
after a few dozen kms.
If your handlebar wobbles between 60-80km/h (aka the shimmy effect), then
it might be a worn tyre, a lousily mounted tyre or indeed, your steering
head bearings.
Check the preload on these "angular contact ball bearings" (thanx, Lawrence
for the correct terms!), an if necessary, tighten *slightly* (!!!)
If the problem persists or comes back, you'll need to change the bearings
however.
Take the RD03 part, wich is a taper roller bearing
(http://www.skf.ca/products/rollerbearing.html)
or go for the Hein Gericke Part No. 2200 3118 , DM 65.- (AFAIK),
also a taper roller type.
