Points will always be more reliable than any type of electronic ignition on any engine. Yes, they require maintenance. But like carbs over FI, a points ignition can often be repaired beside the road, or at least made operational enough so that you can nurse it home or somewhere that you can fix it right. When electronics fail, they fail completely, and there is no way to fix them. They are also very fragile, especially on a motorcycle.
