ass end movement?

Ok so when I'm at hwy speed I get a lot of jumping around?
Im guessing input error or suspension

I have a 130 rear tyre. And what seems to be stock rear suspension

If you mean there is a lot of vertical movement, then it is likely bad shocks. If they are still the factory units,then there is a 99.9% chance that they are needing replacement.

If the movement is horizontal, it could be bad shocks, improperly adjusted shocks, bad swingarm bearings/bushings, bad steering stem bearings, a bad tire, or improper tire inflation.........

Yeah I feel like its horizontal movement.

Ill try checking the steering stem and swing arm bushings first.
I think the tie is good on inflation, maybe bad balance?

I thought maybe it was just such a thin tyre,but nobody else has had the problem from that...
Is there a ”easy” swap to put a wider wheel on?

A far as suspension, I bought the bike with the suspension stiff as sin.
The PO was a much larger then myself.
I knocked the back down 2 or 3 from all the way up.

Could there be too much/little air in the forks causing it?

yes, absolutely check the correct steering stem adjustment.
thinking tire inflation is correct is.......not, check it. go to manufactures website and follow their guidelines. I screwed with the pressure on mine for days. Finally ironed out all the bugs...I think...in my KZ, smooth ride now

do not put on a bigger tire than is mentioned in the manual. period.

yes, certainly, check the fork air, and DO IT the right way, or risk blowing out those seals.

Spend an hour reading here, and you'll find I had the same problems and the journey I took to fix it. Its likely something very very simple, or a combination of things.

tire prssure correct

good /better rear shocks

avon tires

and enjoy

I ”think” means the last time I checked (last week) it was correct.
And I didn't say tire, I said wheel.
Im looking to getting a wider rear ”wheel” so I can put a bigger tire on.
This is my cruising bike, I want it to look good, not worried about setting record lap times in the twisties.

As far as ”correct” steering stem adjustment, what are you referring to?
I meant checking that it was greased and tight.

The air in the forks is a real bitch because I haven't found a good hand pump with gauge. I just have my soccer ball pump and a tire pressure gauge.

And what avon tires you use?

Assume Nothing,

Check Everything !!!!!
