How do I properly store my bike for almost 3 years?

Hello there!I need to put my Yamaha FZ6 Fazer (2004) into storage until June/July 2022.Why? I'm legally not allowed to drive it yet until then due to weird laws regarding age restrictions based on the power of the bike. Why on earth did I get the bike already? It used to be my mom's but she passed away, and I really want to ride it myself when I'm old enough.​Any help? It'll be stored in a heated storage at my work, but I guess that I still need to make some extra preparations? via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/e1wk3i/how_do_i_properly_store_my_bike_for_almost_3_years/?utm_source=ifttt
