Manor Park Classic Auctions - possibly no idea...!
https://www.ebay.co.uk/itm/396522095994
Estimate £4500 to £5000 plus 18% commission and it doesn't even look that good a condition. If you got at the lower estimate that would cost £5310!!!
Manor Park were auctioning an 1100 Katana end of last year with the estimate at £9000. there was a bid to £7500 - you'd think the seller would have jumped at that, it looked like a £6-£.5k bike to be honest, but they didn't and it went into the next auction.
