Got a real odd one, Under hard braking from speed, the front end shudders severley as the bike comes through the 90kmh to 80kmh range then it's linear braking all the way.
Under light braking thre is no shudder at all.
First things I've tried was getting the front wheel rebalanced (all OK), Disc runout is in spec, Headstem bearings have been checked and are OK
I'm otherwise out of ideas... While the discs are still in spec, I clutching at straws and thinking that I will have to chan the rotors (maybe they aren't "floating" properly..)
Run up and down the Reefton using lots of revs and hard braking and that should fix it!

There are really only two questions in life. 1.Which way do i go? 2.What is the lap record?
Re: worn tyres.. the tyres are basically brand new.. I've had it rebalanced and have checked the headstem & triple clam bearings.
They're all good..
I wouldn't think that it could be fork oil..
And if it was brake disc warp, then I would have thought the shudder would show up under low speed braking..
replaced the tyres and the discs at the same time so unfortunatly we never isolated what the actual cause/solution was. the problem is gone now after doing that so im guessing that if your tyres are new then it probably is your discs.
Fixed the problem.
