If you have the 650 exec model then you'll have to remove the pillion/passenger back rest. Once that is removed your scoot will be left with three holes in the rear tupperware section & that's where the luggage rack is attached to. If you have a standard 650 without the rear pillion/passenger back rest, then you will need to remove the rear tupperware aft of the seat. Once removed from the scoot -turn that tupperware over to reveal 3 areas pre/parked where the 3 holes need to be drilled. Suzuki supplies the same bit of tupperware for either the exec or standard model, and the markings are there depending on the model, and therefore the subsequent need to pre-drill the required holes ex-factory so as to accommodate the rear pillion/passenger back rest, or not - model dependent.
