Eh? Handlebar and front wheel strong vibration

Hey Guys,
I have my 950 adventure '05 but lately I've had a lot of vibration in the front wheel.
When I raise my hands off the handlebar between 10Km/h and 60Km/h, the Adventure goes steady as well between 75Km/h and up.
But between 60Km/h and 75Km/h the handlebar just becomes a whole vibration w/out control at the point that could make me fall and crash.

Specially goes worst off-road when in bumps when the front wheel goes up and touches ground again.

Does anybody have had a similar experience? Do you know what could cause this problem and how to fix it?

Thanks guys.

Andres

Put it on the center stand and spin the front tire. Look for a tire problem or bent rim first.

What tyres, part worn scorpions cause this.

Actually I find part-worn pretty much anything causes this, especially if I've been road riding and heavy on the front brake.

I have a part worn Scorpion front tire, however the problem appeared after installing the brand new...
I got it balanced but didn't work-out.

Did you made any changes other than the tire?

If not, it must be the tire.

What's the air pressure in it?

None, just the tire.
I normally use 28 -30 psi front...

Tomorrow I'll change the rim for a new one from Behr, move the hub, discs and spokes, get it all balanced and see what happens...
I'll check suspension bars torque, triple clamps and wall-nut again, so far those where correctly tightened though.

Bluhduh

Any other solution to this problem??? My bike has new tires, actually is brand new... I guess there are no worn tires or parts on my bike but it's exactly the same problem, between 60 to 80 Km/h if you don't hold the handlebar strongly... kiss the road

Have you checked wheel bearings?

I had worn wheel bearings and the result was wobbling of the front wheel.
You could sound- check the spokes. I had one broken once...
Cheers.

Scorpion. Stand up, lean forward and look at the tire while it's rolling. Looks like a wheel out of true. Can't wait to get mine off.

Loose the Scorps...

This same post appears year in and year out. The 950 stock front springs are soft and causes a dive to the front end. The front Scorpion wears unevenly due to this dive and the weight imposed on the front wheel. The Scorpions along with the Behr front wheel don't balance well either. Also the Scorpions do not wear well with tire pressure below 32 psi on pavement. Add all of this up and you'll constantly hear complaints about "head shake".

I"ve experienced this very same problem with fairly new Scorpions and pitched them immediately... problem solved.

My personal opinion of the Scorpions are they suck anyway. I'd rather ride an extremely worn set of TKC80s on the pavement.

Now, my current Scorpion Rally front tire is working really well and would also make a much better selection.

But then I'm of the belief it's better to have a more aggressive tread pattern then a lesser one. And an extremely worn out aggressive tread pattern is as good to me as a worn out street tire... where bald is bald.

Just my humble and biased personal op. YMMV.

Same problem, new bike

Hi guys! I was reading this and I´m worried about this because my bike is brand new, 3500 km and it has this terrible vibration between 50-75 Km/h and some days ago I was trying to fight with a S Teneré 1200 and a Vstrom 1000 and when I was reaching 190 Km/h, the bike was going from one side to another, very strange but I got scared and preffered to release accel and see the other guys leave me behind...

I have to check if maybe the problem is the rim but I really don´t think so...

Let´s see what´s going on

Behr

First off, don't replace Behr rim with a Behr Rim. Get an Excel or Dirtstar DID.
1.85" way stronger than stock wheel. And costs less. And I put in stiffer front springs to avoid bottoming out while off road. No front shake ever.
