I've noticed before that the bike feels wobbly above 115km/h. It feels really scary so I actually am afraid to ride it above that speed. I thought it might be unbalanced wheel or wheels, so since I will be changing tyres soon, I figured I will check then. I rarely ride above 100km/h so I wasn't bothered much.
Today I've noticed that the bike wobbles more (or it's just my imagination). All the bikes I've ridden before were very stable. You know, when you shake the steering bar at around 80-90 it will give you a wobble and you feel that it pulls you out of that wobble. Shineray, on the other hand feels like it wants to wobble more and I need to intervene. It's really strange.
Thought it might be soft suspension so I wanted to adjust and the front feels like there is no difference whatsoever on softest and hardest setting. Also the adjustment nut is significantly easier to turn on the left side. Rear shock seems OK.
Anybody had a problem like this? Or tried to adjust the forks?

Check Head Bearing and wheel spokes tension and tyre pressure?

I had ridden the X5 up the 130kmph and had no notice of what you describe.
Follow the Prince's advise.
Additionally check how easy your front wheel is rolling to make sure there is no bearing defect.
I ran the original Kenda tires without problems.
BTW: the forkchas adjustment possibility also at its lower ends.
(Already considered?)

I played with that fork adjustment today, turns out it take few hundred meters to kick in.....
Once you turn the adjustment screw (14 clicks) nothing really happens to the suspension. After riding for a while it gets harder or softer respectively to your adjustment but not by much. Actually the difference is very slight.
Also, they try to trick you...haha there are big letters "S" (I thought for soft) and "F" (I thought for firm). S is clockwise and makes the suspension harder and F is anticlockwise and make the suspension softer.....go figure
Anyways, on the hardest possible setting the bike feels a bit more stable but not as it should. I will inspect and let you guys know

Re: Shineray / XinYuan X5 review
I tried to change the tyres today so I had a chance to inspect the bike a bit. The steering bearing seems fine, spoke tension also ok, wheels spin smooth. Im guessing its the balance but they dont have a way to check it there in the shop.
Eventually I didnt change the tyres cos the new ones are too big. I got myself Metzeler Karoo 3 140/80-18. Earlier I went up 2teeth at the rear which pushed the wheel forward a bit. This and a beefier tread resulted in wrong setup (chain too short). Also the tyre rubs on the chain guard so I will have to trim it a bit. Anyway, I have to buy a new chain so I also decided to change the rear sprocket to even bigger one, 44teeth

Hi Modron
You can static balance you front wheel very easy.
Yeah, I know its easy yet I dont have the right tools. I tried to use a pit bike stand but no luck so I decided to leave it for now. I did place a random amount of weight opposite a rim lock but had no chance to ride it yet. Will see how it goes
