99% of the bikes for sale out there today are not high end machines. Their homebuilds made up mostly of ebay and scrapyard parts. Not that some of them arent nice. But... Not every bike is worth a fortune. That's a fact. I don't care what you paid for your overplayed gas tank, or how much money was spent on powdercoating. Its still likely no better than any other bike on the market. But, because the hip kids with fat wallets and old men who think every (insert model or make) is somehow a gem in a pile of coal because they owned one back when they could still fuck without pills drive prices up now everyone thi ks their bike is worth a fortune.
Your time isn't worth anything to a buyer. Good luck charging them for it (unless their the above mentioned "trendsetters"). Total cost of parts doesn't matter either. Their is always a cheaper one for sale somewhere.
Now, I'm not saying that many of us don't build some AMAZING machines. Many members here have. Many more who arent DTTers have. Hell, folks have been doing it for decades in countries across the globe. Until the "me me me" internet heros came along, nobody thought the cool bike they were building was some fucking holy cow though.
You want to see a bike that's worth a bunch of cash? Check out Falcon Motorcycles, Confederate, Greggs Customs and many more. Look up the story of the Britten bikes and their brilliant designer/fabricator. Those are the guys changing the game. Those are the folks giving us something to strive for in our own builds. New engineering. Real handmade parts from crazy materials. Groundbreaking design.
You get the point...
We need to stop glorifying these fly by night shops and barely interested homebuilders by paying into the hype. Less "hey, my bike kinda looks like the one some yuppie douche built and I saw in a magazine, it must be worth a million bucks". More, "I want to build the best bike I can, and if I decide to sell it Ill keep my fucking head and ask a real world price".
Get what ya can, but don't be pissed when someone tells you your golden chariot is more of a good old fashioned motorcycle. The real world sucks sometimes, but after the rose tinted glasses get stolen by the next trendy fuckers, it'll smack you in the eye.
