The crush washer is just another bit of cheap insurance; changing it every oil change or every other, is not a bad thing.
I recently asked a parts guy at a Suzuki shop for a crush washer for the DL650. He gave me a crush washer but it turned out to be too large. The drain plug on the 650 is actually quite small. I ended up using the old washer with no ill effect. Next time, though, I think I'll lay in a small supply of them.
