Front Rotor comes apart

Never seen this before but my 2004 450 FSE Front rotor split at one of the slots. Split at the top of the slot and at the bottom . This caused the rotor to spread out with a 1/8" space.

Didn't happen when I was riding so there was no accident. I did not hit the rotor with anything as I was using the bike to do some paved back roads. All was well when I got home but the following morning when I went to pull the bike out of it's slot I noticed that the front wheel was dragging and catching.

I looked at the rotor and was definitely surprised. Evidently over the cold night it just split from accumulated stress.

I have never thought much of slotted rotors. I have always preferred the type with staggered round holes. They just seemed to have a better engineered design in that they dispersed the stress levels across the rotor more evenly.

Anyway, just thought I'd mention this.
