   G'day, My K4 1000 has severe front brake shudder when washing off speed at the end of straights at the track.
   I have read in different forums that it could be caused by a number of things from steering head or wheel bearings to warped rotors wheel out of balance etc. The brakes are stock for now but will be updated in the near future.
   I have tried extensively to replicate the shudder on the road, (at the same speed and same force as the track) but the brakes perform fine, which brings me to my question, could it possibly have to do with tyre pressures, because thats the only change I make to my bike between road and track.  Cheers.

    Logically if you are doing it exactly the same on the road as at the track and the only difference is the pressure in the tyres, then you would look at what that means... the lower pressure takes some of the resistance away from the fork (also increases footprint/friction). I presume this is a stock front end?

    Either way, look at oil, springs and compression - it could easily be going inside the hydraulic locks (if it has them) too early and shuddering from the damping increasing exponentially/suddenly.

    Hope that helps.

   Thanks for your feedback Zeno, the front end is stock, I don't know what hydraulic locks are or if it has them, but you have steered me in a different direction of thought, maybe my money would be better spent on upgrading fork internals at this time and upgrade brake components further down the track when finances permit, once again thanks for your reply
