feel a slight tilt on going straight

My guess would actually be the crown in the road. Typically they are higher in the center than the outside of the lanes for drainage purposes.

I once went on a multi thousand mile road trip with pretty sticky rubber and it was noticeably more worn left of center on the tire.

Hope this helps ease your worry, but sometimes you are leaning into it even if it's a straight line.

+1 on it just being the crown of the road surface. Some roads have a very pronounced crown to them, especially in places where it rains a lot, so the water runs off instead of pooling up on the road.

Slight gusts of wind can also be a cause

Cross-wind or roadway cross-slope would be my first guesses. I'd do a quick check of the chain adjusters too, just to make sure the rear wheel is centered in the swingarm.

Found it, the tire is too senstive. It was2.5 psi higher both. Now exacyly 29 & 36 the feeling is gone.

The michelin is just too sensitive, never experienced before

Can you explain that in easier english for a german guy whos english isn't that good to understand what you exactly mean with 2.5PSI and 29 & 36.
Thanks mate :3

That means it was 2.5 pounds per square inch of pressure too high. The manual recommends 29 PSI front and 36 rear I think. That's what he meant.

Probably don't need to say this but just in case: make sure you adjust the tire pressures when the tires are cold or you will end up with under-inflated tires....

with the stock tire, michelin pilot street, you need front 29 PSI and rear 36 PSI, 3 PSI higher and you will kind of feel the elevation of the road.
