We have a local place (Cycle Salvage, Peterborough Ontario) that does a good business on used motorcycle parts. They do sleds too, been open for decades. They usually remove decent pipes, bodywork, tanks, seats etc, then roll them into neat rows, outside, in a huge yard, out back. It’s reasonably tidy, and customers can walk up and down the aisles. Must have been 4-500 bikes. Some were literally “melting” away. A few years ago, they did a massive clean up. Next time I visits, will take pictures. Neat place.
