I have been struggling to get the disc rotor off my front wheel on a 2002 426. I have nearly stripped both my 6mm Allen Wrench and the rotor bolt. Is there a trick to this. I used liquid wrench but is there something else. It does look like there may be some locktite on them. It is the original rotor and I'm betting has not been off since the factory. I am getting dangerously close to ruining the bolt. Any help is much appreciated.
What Dave said - use a 6 point box end wrench to loosen the nuts behind the rotor. You may even have to double up with another wrench to break the nuts loose, as it's hard to get enough leverage with a standard short wrench. I slip the box end of a larger wrench over the open end of the wrench on the rotor bolts to double the length/leverage, like slipping a pipe over a wratchet. You use very little force on the allen key, just enough to keep it from turning after you break the nut loose. Most of the time you can break the nut loose without holding the allen side at all.
Yes on the locktite. I bought a couple of spare rotor bolts and they came with factory thread locking agent.

I'm pretty sure there are no nuts on the rotor bolts, they should thread into the hub. Steel and aluminum corrode when put together, which makes the bolts very hard to get out if the bike is older. Try using an impact driver with a good Allen head on it.
KJ is correct. The rear has nuts but the front bolts thread right into the hub. My mistrake.
