I also have a 2021 Ninja 650. She's got less than 7,000 miles on her. About a month ago, my clock just randomly reset itself. It's only happened that one time and it was just the clock that was affected. I checked the battery connections and all was secure and clean. This morning, when I went to start her, my battery was dead. When she came to life, the check engine light was on and stayed on all the way to work. I'm headed to my dealership tomorrow to find out what the heck is going on. I ride my bike almost every day and have had no other issues. Have you taken yours in for service? I'm sure that if there's an electrical issue, it will be covered under warranty. 🤞
