Dear Customer. Thank you for ordering your 90’s Parts with us. Please note all parts are New and Unused Genuine Husaberg Factory Parts – New Old Stock! They have been put away in storage for over 20+ years so some items may have ageing, Blemishes & Marks etc on them, which is to be expected due the age of all the parts. We hope you enjoy having these original parts on your bike, especially since they have been unavailable for such a long time.
