Is your rear sag set correctly? What is the static sag and your race sag numbers? Proper springs front and rear for your weight? Too little sag in the rear can cause an unstable front. I have an '05 also and run about 105mm race sag. More sag in the rear increases front trail, which in turn increases stability.
In the front, run the fork tubes flush, or even, with the triple clamps, so that none of the fork tube is showing above the triple clamp.
I almost guarantee the issues yoy are having are due to improper suspension set up. These bikes are ultra-stable when set up right.
Same issue here on an 05 FS650E.
Below 80mph it's perfect. Above 80mph the front seems light and begins to wander. Maybe partially due to aerodynamics or too tight a grip on the bars.
My front forks are two marks above the top clamp. I'll try lowering them the first mark or flush with the clamp and/or resetting the rear sag and see what happens.

add a little rebound on the rear and take-away rebound on the front.
check the headrace.
set sag as said between 100-115mm.
put a zip-tie around your fork leg and check how much travel you're using.
start to concentrate solely on suspension for a little while.
go into the owners doc. although i don't set out basics there-the owners books are for that-i do get right inside the forks and i hope that it is jargon free.

I assumed sixdays was talking about his 'Berg being in "dirt" trim. Plus, there's a big difference between 80 kph and 80 mph, which you are talking about.
I don't have any experience setting one of the FS bikes up, or any supermoto bike. The suspension is shorter travel, I think?, so the same sag numbers that Taffy and I threw out there would not quite apply. General rule of thumb is that static sag should equal 1/3rd of total available travel.
The principles remain the same, just not the exact measurements.

All the above replies are good. But, keep in mind for more high speed stability you want to raise the front or, and, lower the rear. Just the oppsite for turning quick.
