If the experience hasn't put you off motorcycling, I recommend taking a refresher riding course, or better yet, a traction course like Skidbike. You likely low-sided due to hitting that front brake rather than progressively squeezing it.
Also, if you do take a Skidbike training course, you will be shocked at how good ABS is. Some friends and I took such a course a couple summers ago, and with the ABS disabled, we all low-sided the bike (outriggers prevent a full crash) hitting the front brake. With ABS enabled, none of us were able to provoke a low-side.
Lastly, using the rear brake in slippery conditions is the worst take-away from your experience. While over / abruptly applying the front brake can result in a low-side crash, the same overreaction with the rear brake can cause you a high-side crash, which is a much worse day. If you do find yourself with the rear end skidding, KEEP the brake on. The risk is in getting startled, letting off the rear brake, and regaining traction. This happens violently and is what throws the rider off the bike in a high-side.
The reason for the accident was it was a European spec bike so the brake levers were reversed. It was new and I just hadn't internalised that switch by the time of the accident. If I had hit the back brake I would have been fine.
Ah, I missed the thread change. Oddly, motorcycles use the same front brake lever position as the bicycles in most non-US countries. It is indeed confusing when they are swapped as such.
