When l took delivery of DVT l was given spare lock barrel which is same key fitting as everything else ie seat fuel cap and panniers. I am using my V47 top box from last Ducati (st4s) which l hardly used and has red short key. I thought l would change barrel so only one key needed but new barrel looks to be too long anyone know if there is a conversion kit to take the longer barrel. Might just have to stick with the separate key.
