Yes, on the whole I agree with most bikes but this one it just doesn't seem worth it - getting to £15k is a struggle then you need profit on top.
Maybe correct maybe not. Assuming it is not stolen we do not know price he got it for and I would expect all of it sell for 16-17k
Whenever I've broken a bike it is typically +3 years old and I've bought it all tricked up by some barrister (criminal charges) or oil rig worker. I at least double my money then I'm left with a frame, v5 and various plastic bits like battery trays etc Back in the 80s there was a famous breaker based around Farnham and Aldershot who was famed to buy new bikes and split them. The very week a new model was out they'd have the whole faring for sale at 95% of the list price. Eventually they got greedy and got caught with loads of stolen bikes and parts. The main players did serious time.
There's a chap near me who is selling an 1199R with 3k on the clock for £15500. It has many expensive extras on top of the extras you get with an 'R' model. He's selling it openly and honestly as an ex track bike. It's low mileage but the miles will have been hard but it's priced accordingly. Now there is an opportunity here for someone unscrupulous to buy that bike and break it as a low mileage bike in excellent condition (ring any bells?), which technically it is and charge top dollar for the bits. The unsuspecting buyer thinks they're getting a good deal, which maybe they are if they're buying panels or non mechanical parts, but when it comes to the engine, suspension and other wearing parts they could be buying a can of worms. I still struggle to see how it stacks up. People who break bikes must not be declaring the money they make to HMRC as they would take the profits in tax. This is ok if you're an individual breaking your old bike but there are people on eBay etc who do it as a cash in hand business.
