luggage rack for Skorpion Sport vs Tour - subframe question

All,
I found a U.S. distributor (from a British company:Motohaus Powersports Limited, us dist:http://www.ventura-mca.com/) for luggage racks that fit the MZ 1000 and the skoprion sport.
My question is whether the sport and tour subframe are similar enough for this rack to work easily. So, any input?
