front end unstable while cornering

My bike is getting a weired slight shake well it just feels unstable when high speed cornering. What do you think the cause is i believe tire preasure is good

How long have you had the bike? Has it always done it or recently started?
Culprits are dodgy suspension setup, knackered/tight/loose head bearings, sezing suspensions linkages, or most likely you not relaxing properly on the bars if you're new to the bike.

I have had the bike for a little over a year and but 7500+ miles on it it has been in the last few days i have noticed it doesn't feel right and my thought were something wrong with the tire, wheel bearing or, head bearing. It feel like a steering damper would cover up the problem but i want it to be right

Rebound damping is too soft on these bikes. Stick some thicker oil in (15W or 20W if you're a lardarse). Check your sag setting too (preload).

Using the front brake in the corner? Lots of people do without noticing and it can make corners tough as the suspension geometry changes through the bend

What are the tyre pressures? Some people find that going higher or lower than the manufacturers spec helps. Ideally it's 33 front 36 back but some use 36 front 42 back. Too high can make the bike feel like it has reduced grip, too low can make it feel sluggish.

How old are your tyres? By 7500 miles the front will be knackered if it's the original tyre, and the OE tyres that come with the biuke are rubbish anyway

Any obvious wear or flat spots on the tyres? If the tyre (front or rear) has a flat spot that can make leaning the bike over scary as it goes from the flat to a point before getting onto the curve of the tyre, so leaning over and back up are awful, though it's OK when at full lean.

Other stuff - something could be loose, you could be wearing thick gloves which mucks up the handling/feel of any bike... but those ones above are the main problems.

That could be it. I have just backed off the rebound damping on my CBR back to factory settings and I am getting an unstable feel at speed. I'll whack on a turn of rebound damping again to see if that helps.

It could be any of the above, also when you say high speed, whats high?

So in order
Head barings (Check of tightness or if they are worn)
Tires - As said at 7500+ they will be past thier best
Wheel straightness
Suspension - Oil and springs will help

Somone will be a long soon to say that you need to swap the whole fornt end over for a Gixxer front end etc etc. Ive done 50k on my bike, and im still to think that it needs doing.

when you say high speed cornering how fast we talking? my 650 used to act all weird front and back on 100+ big sweeping bends, i just put that down to budget shocks.
