Some very very nice bits on there mate
You will be robbed blind mate if you try and sell as a complete. No doubt whoever got it would probably split it and double their money.
I'd definitely split it and sell it here on rad so you wouldn't get screwed over price or ebay fees!
The wheels alone are worth around £700 mate....
You'd have to price it somewhere around £1500-£3000 and no one has that kind of cash lying around for a survivor bike
Some of those parts are in great condition too.... A complete 3 piece pad set is super rare.
Keep or sell it in parts....it's a no brainer.
I'm sure ever bit would sell in minutes on here
