Front Wheel Judder

Ok, im not too bad with a spanner in my hand, but I am not the best when it comes to diagnosing what is the cause of a problem . So lets see if you guys (and gals) can help me out.

Problem 1. The handle bars shake like a washing machines when riding over a ton... not that I do it too often.
Problem 2. The front end judders under braking from speed.
Problem 3. The front end clonks when applying brakes at slower speeds.

So peeps, what do i need to do?

Thanks!!!

That high speed shake is worrying... perhaps wheel bearings, bad wheel bearings can also give a shudder on braking. So this is what I'd check first.

Have you had your wheel off lately? Someone might have left some bits loose, on the AR last year someone had a tyre done and notice a high speed wobble, and it was because his spindle had not been tightend up properly.
Could also be a warpped disc, but as Chris said, check your bearings too. Might be a idea to take the front wheel off and give it a good check over.

Most SV's clonk when braking, unless its a new thing to you.

High speed shake could also be something as simple as a slightly unbalanced wheel.

Is there any chance the clonk when braking at low speeds indicates possible loose head bearings? Does it clonk over bumps in the road too?

Be interesting to see if you find out what it is.. I have exactly the same issues with my cbr except the high speed wobble..

I've had it checked over at two dealers who can't find any problems, this is after replacing the discs and the pads after the initial check over as one disc was warped

Yep, maybe the weight fell off?
