Derbi Variant MT Seat ee.001.01 you probably weren't planning onNew MT seat for Derbi Variants. This seat has a rear hinge with a front latch and is for Variant Sport type models with the Flat Reed engine. Has a new lock key in the latch but you will have to reuse your old hinge pin and spring with this seat. This is not for Derbis with a Piston Port or Pyramid reed engine. Compare to your original to see if this is a match.
