I'm no expert so take these prices as a very rough guide & to a certain degree it will depend on what racks/rails you are talking about but the cases I would guess to be in the region of £100 each and the frames £150 or so. As I say it does depend on the model & in the end they are worth what someone is willing to pay. Some pics might help with a more accurate assessment?
I'm looking for a second hand Touratech topbox either Zega or Zega Pro for a project I'm working on.
I've already got a set of black Zega Pro 'limited edition' 38/45 and a topbox aswell on my 1200GSA as a set of standard Zega 29's on Mrs P's G650GS and a pair of standard Zega 41's on my G650GS Sertao that I found very cheap on Gumtree.
.
Prices depend on the model with standard Zega's with racks going from around £400 and the special cut out systems making a good bit more............Individual boxes go fro £100+ and racks from £120 depending on finish and condition etc as the steel ones rust but are easily repainted..............Some racks are stainless steel depending on spec.
Zega Pro's are usually a lot more expensive especially the annodised finished ones with stainless rack fitting kits.
Travel stickers can add value aswell but then you could fall foul of the old 'sticker fraud' rule.................!
