Ever dremel a rotor?

[md30]

In order to make a disc lock fit? I have a Xena xx-10 (10mm pin) disc lock that I got for my drz400 with original rotors, but it wont fit on either rotor. I'm thinking of dremeling the rear a bit to get it to fit. Will it rust?

There sure is more then one way to lock up your bike other then trash a good rotor!

No, it will not rust and the amount of material you remove will barely affect wheel balance. Just be sure the chamfer the hole.

I wouldn't be trashing it. There's already slots in it like all rotors have, it just needs to be slightly enlarged

I would do it only if its a couple mm's. Much past that I would go with another option for lock.

People cut slots and drill holes in rotors all the time. It won't hurt anything.

You ever notice how all those slots are perfectly symmetrical?  Wanna guess what happens when you remove metal in a non-symmetric manner from a part that spins at high speed?

dont worry, i sliced a few knobs off the tire on the opposite end to counter balance them ?

A brake rotor certainly does not "spin at high speed". At 60 mph a 21" front wheel is doing about 800 rpm.

Do you think the wheels and tires on your dirt bike are perfectly balanced? Or even close to being balanced? With that giant rim lock on one side?

Removing a couple of grams to make a hole slightly bigger for the lock isn't going to hurt a thing.

Looks good to me.  I've always balanced ALL my tires/wheels, I don't think I'd even check that unless I already had the wheel off. ?

The problem I have with disc locks is 2 people can still just pick up a dirtbike and throw it in the back of a ute in a matter of seconds. Prefer to chain/cable it to something solid.

nah i was never worried about the balance, that was other people who brought it up, i was just worried about developing rust. plus i filed it down on each side anyways, not for balance, but so I would always have one slot exposed for my disc lock.

plus getting new tires this week anyways!

That's close enough to the center of rotation that it will make zero difference. Good job. ?
