Hepco & Becker Speedrack. Purchased from an authorized dealer. Documents are also available. Can be installed on YZF-R6 from 2017 onwards. All accessories are included. It's clean because it was never used. The metal fittings are assembled, so please make adjustments yourself. The rain-prevention sponge is temporarily attached, but the adhesive is weak, so you may want to reapply it with double-sided tape.
