No, survivorship bias would be looking at motorcycle injuries by only talking to motorcycle injury survivors. Your conclusion would be that motorcycle injuries only result in minor small damage like skin abrasion, broken fingers, etc. Your conclusion would be that brain injuries basically never happen because all the survivors you spoke to were fine.
If you're looking at casualties from motorcycle incidents, you by definition are not looking at survivors.
