CRF1000 Head Shake?
« on: October 04, 2016, 12:26:52 pm »
Any other owners having this problem? My bars start wobbling at around 150km/h and since I fitted barkbusta hand gaurds (removed internal bar weights?) its got way worse? Bike came with Mitas off road tyres and I see I still have factory wheel balancing weights, not sure if front was supposed to be re balanced? Any thoughts.......

I would imagine it to be a case of needing to be rebalanced after the tyres were changed?

KZN1, was it on tar or gravel?
Might be that your rear suspension is set too soft.
I had the same problem on gravel with the original demo bike, problem disappeared after the suspension was changed from stock to semi hard.
I have also removed the internal bar weights on my bike and it had no influence on handling.

Also got Barkbusters on mine and no headshake. I would look at your suspension settings.
Also check head bearings.
Always keep your "kant" clean !

likely rear suspension prepload to soft.

2 days ago someone told me his 1190 has headshake at 160. I tested his bike, but no headshake. So what has changed, I am 80kg and he is 110kg...
it important to get the rider sag sorted.

Ok update, firstly thanks for advice. Did the tyre pressure check and set the sag (compression up back and front) this seemed to improve overall ride comfort and moved the start of head shake up from around 145km to around 160km/h?!

Then yesterday at same speeds simply shifted weight back on seat and head shake stopped???? Slid forward on seat and head shake started again.....? I'm 92kg and 1.92cm in my birthday suit so back to suspension settings ?

KZN1, I can't believe that you have this problem, my bike is super stable.
Have you checked that both front shocks have the same setings?

Head shake is influenced by many factors, e.g. steering rake angle, weight distribution, etc. Some items are fixed and cannot be changed easily. Others such as tyres, etc. can be changed easily. A specific tyre brand/type could also be more susceptible to head shake on a specific model of bike.

Ironically, I found loose fitting jackets can cause the steering to wobble
