Sounds similar to what I experienced. Was it on the same piece of corrugated road you experienced the head shake? Have you had similar head shakes on your previous bikes?

Ek byt nie so lekker aan die band druk storie nie, sagter band druk ry wel beter en sagter op verskilende opervlaktes maar ek sien maar min ander ouens wat heeltyd stop om band druk te verander, ek het al self met harde en sagte bande en sonder 'n steering damper in verskilende omstandighede gery sonder enige probleme,


As band druk die oorsaak is dink ek daar is dalk 'n suspension of ontwerps probleem , ek dink hier slaap 'n ander haasie hier  :deal:

Remember that hapiness is a way of travel - not a destination.

Tend to agree with Jakkals. I suspect the LC steering geometry, weight distribution and suspension characteristics makes it sensitive to head shake. From my experience, the message to fellow LC riders: Beware when traveling on corrugated gravel roads between 80 & 100 km/h- you may encounter an unexpected , violent head shake.

those eco gravel roads had not just the normal corrugations.  but - not sure what you call it but it was like continuous big corrugations, every now and then and just like the small corrugations, this carried on for different distances, some times a few meters - some times more. i have never seen a road or conditions like that before. 

i must admit and agree between 80-100 the bike did not like those big continuous corrugations, however at speed no problem and the small corrugations no problem.

The gravel roads where so straight, so most of the time we were way above that speed anyway.  as said conditions dictate when it happens.

i thought it was only me, i even blamed the bigger screen i had added!

and my uneven worn front tyre did not help.

i had the biggest of shakes several years ago on gravel, that ended up in a major tank slapper, this was on my v-strom 650 suzuki, it happened as i de-accelerated for the T junction- it hit me hard and went on for several meters and then disappeared as fast as it started.  how i saved it i don't know??  it was the type of tank slapper that you see in those video clips, just before you get thrown off the bike, it was so violent that my arms and ribs hurt for a while. 

it can happen with any bike.

The corrugations causing head shake where not at 90 degrees to the direction of travel.

Mine was a V-Strom DL1000.  On tar, slowing down for a T-Junction and hit one of those "WAKE UP!!!" riffle thingies they have these days.  Major headshake, but it corrected itself before I could do anything stupid.
