MK Katastrofa is a motorcycle klub from Zagorje ob Savi, Slovenia, although our members come from different parts of our country. We are gathered mostly of course because of motorcycle enthusiasm and love towards rock'n'roll lifestyle. Our klub was established in 2006 and since then we've driven in almost every part of former Yugoslavia and also in some of our neighboring countries. We were also hosting different social events, like bonfires, winter parties etc. In 2013 we organized our own bikers' meeting, called Nuclear Weekend, for the first time. Since then we are organizing it every year and it traditionaly takes place on the second weekend in August. Already at our first Nuclear Weekend we received a very good feedback from our guests. That's why we do our best every year to stay at the same level and at the same time also improve.
