Pretty much explains it.
When i hit the brake the whole front of the bike shifts forward, the whole triple tree moves about a 1/4 inch forward then goes back into its normal position.. at first i thought it was the forks but they seem good and arent leaking..

What else could it be?
Bearings somewhere?

Steering head. Remove the triple and tighten the head bolt. Or remove and inspect the bearings. May be worn.

^ what tripage said - but I would stop riding it and get the bike to a mechanic asap.

If you are wondering what this is and what you should do about it you should definitly not do the work yourself.

Probably your steering head bearings. Use some jack stands or some method to get the front end off the ground, then move things around to see where the slack is.

if it's the steering head bearings you can tighten the nut under your top clamp to take the slack out. If the slack comes back your head bearings need to be replaced.

If they slack back off again it could also be a sign of under-torqued triple clamps.

Any play in the bearings will accelerate wear. So if your top clamp is secure to the forks then its your bearings that are loose, whether theyre worn or untorqued. I wouldnt even think twice - just drop in a new set of tapered bearings which are better and will cost you a fraction of the OE set.

I wouldn't go with those, a few blokes have had trouble with their wheel bearings...

And its your bottom clamp that will cause the bearings to come loose.

:+1: on the tapered bearings though!
