Hello All,
I was out early on Sunday morning to make the most of the empty(ish) roads and to enjoy some 'spirited' riding and discovered that the bike starts to weave and move around quite a lot at speed, particularly when cranked over in long bend. The motion seems to start at the rear of the bike and moves forward through the bike until the front goes light - kind of like riding with a punctured rear or very low pressure. I was riding in 'Sport' setting and was pushing on a bit and meant to go back and repeat the test in 'Race' mode to see if made a significant difference. Has anyone else experienced this at all? Ive seem some comments about it on other forums.

Im still riding on stock suspension settings ( I weigh 90kgs without gear ) so it maybe that the rear needs stiffening up a bit. Tyre pressures at also at factory settings.

The handling woes continue.. the bike feels almost like its loose in the middle and weaves and moves around all over the place when its lent over, so much so that it/we've run wide on a couple of occasions.
I have changed to race mode and repeated the corners and whilst the movement is a bit less its still very pronounced and not confidence inspiring - the 1098S used to corner like it was on rails and was completely stable, the 1199S is like being on something that is about to throw me off. I have had a good look around the bike to look for anything loose or any excessive play and can't see anything obvious ( I rebuilt an R1 from a bare frame after a crash and impressive fireball at Silverstone so Im reasonably handy with the spanners ) but cannot fathom what could be wrong with the bike. Has anyone else experienced this? Its going in on saturday for the full system to be fitted whilst Im away next week so I'll ask the mechanic to take it out and see what he thinks as he races so should have a good feel.

A not very happy Ben.

Not actually played with setup on an 1199 yet but if I was happy a bike had been set up (springs/static sag etc) to suit the rider, and they still said it felt 'loose', my instinct would be to increase rebound to try and dial it out ....

Just read a write up in Bike and they talked about it not liking bumpy roads and tying itself it knots, example given was bottom of mountain at cadwell and a bumpy b road. Also said it handled like an IL4 more than a twin

I read on another forum and from an 1199 owner that all the early bikes were set up with the suspension set up for track use and that they had to change it over to be able to get any change in the feel of the bike.

I think they said they had to move the adjuster (with the arrow) on the rear shock linkage to the opposite of where it was was when it was delivered.

Or this !!!

Lets hope its not that! Im getting plenty of feel from the bike.. it feels like its trying to weave and shake me off. I hope I haven't got one the of the old legendary 'Friday Afternoon' bikes.

Does anyone know what difference it makes moving the rear suspension linkage from flat to progressive? I asssumed that the bikes would come set up for the road but perhaps not?
