On my MS Pikes Peak (pre DVT), that's with Skyhook suspension. I get a strong weave, not quite a tank slapper, but no way one could take hands off the bars at approx 200kph. there is no sign of it at 180kph,,,wierd I check tire pressures,, front tyre is in good nick, rear is about 3/4 used Ant ideas where to start looking/
I think its one reason they lengthened the wheelbase on the 1260. However, I've also had a tyre that did that even though it looked perfect.
As above. Can be tyres ( type of tyre, or Pressures) Luggage, even empty, or weight distribution. Road surface, unless it happens on many different roads. Unfortunately these things are often trial and error, and the same setup on another bike/rider can have different effects.

If you do a search on this Forum it covers it by members who have changed lots of things and done trillions of miles on these models.
Thanks all I can eliminate luggage as did not have any, tyre press I can check again Suspension setting is a black art as far as I'm involved. Will read up on the info suggested I will let you know how I get on @ West Cork Paul,,, I'M a Cork (city) man myself,, get there once a year or so
another idea i heard, was aligning the front wheel. To avoid miss alignment when refitting the calipers after a tire change, make sure the brake is on when tightening the caliper bolts. any one heard about this idea?
As your on Ian, in particular, is rear suspension set really low and soft compare to front and were you carrying a pillion and full panniers at the time?
Just one up, and no luggage I take your point about the settings, I will check the suspension setting
On my last but one bike some owners mentioned a slight shimmy at certian speeds, a lot of those reported using a top box at the same time so and when removed it didn't shimmy. Whilst the bike was designed for a top speed by engine and aerodynamics, putting a brick on the back may have had a amplifying effect of another issue Tyre pressures where the first, then headset bearings, surprisngly wheels not being balanced and not checked since the last time a tyre was replaced often was the issue
bit cryptic but was hinting at "some owners" rather than "first hand experience" all the things you mention in your last sentence are worth checking of course but "most owners" tend to have checked these already but still the problem persists. The top box was a good "outside the obvious" tip though.
As Pete says, have a search, there’s a fair amount of points of view and experience already on the subject.
Agree ^ but there's also a lot of Internet folklore dross out there plus, if you trust the person* then there's nothing wrong with adding some first hand experience, i'm sure more will appear soon.
If suspension is a black art then take it to a specialist tuner, can’t speak for your location buts it’s £40-60 here.
