Standard-fit is 2 x 25mm wide straps at the front (independently down to rad. mounts or joined together around the headstock). 25mm wide straps at rear locate on self-adhesive velcro under front edge of seat. An alternative fixing method can be supplied for bikes, where the seat does not easily move at the front (some Ducati & KTM models), this fitting hardware usually replaces the rear velcro solution wit 2 x loop straps which locate on the bike's frame.
As long as your front seat-edge can move, you will be ok with the standard velcro solution.
