I decided to try some bar-end mirrors on my WR250X. I removed the bar-end inserts, and clamped the mirrors to the bars near the cross brace. Worked out great. They take some getting used to since you have to look down at the mirrors, but once you get them adjusted to your liking, they seem to work great. And they look a lot better than the stock mirrors since they are tucked down low and out of the way. Here is a closeup view.
