Promoters are SML (SML = Finnish motorcycle association) and local clubs. Series is connected to MX2(lites?) and sidecar championship races. A club that wants a MX2 or sidecar championship race (held on sundays) must organise a MX125 league race on saturdays, which here is a league series day. League classes are MXJ(under 18),MXB(over18),MXD(womens), MXV40&MXV50(vets,a championship class but organized with league) and now MX125 league too!!!
Series is at least seven races; four with MX2 and three with sidecars. Also any club can have MX125 class in their non championship races if they want
