This is a set of a HONDA genuine top case and a CRF250L rear carrier. It was originally on my CRF250 Rally MD47. (I've included photos of it installed for reference.) The inner lock cylinder has been removed, so please purchase one separately. You can find installation instructions online, which should be helpful. The installation itself isn't difficult. HONDA genuine parts are expensive, and you have to buy them separately, so it can be quite costly. I'm not a big fan of panniers, so I'm selling this. I will be taking this listing down for a month on July 22nd, so please act quickly. Thank you for looking. Manufacturer...Honda Vehicle Type...CRF250
