My 10-4 to the Gryph comments & others. What he spent to create his concept is the price you pay for personal obsession, and has no correlation to value. Market value of a running K100 is very much dependent on geographical location, condition, mileage, and history. That he has transformed it from stock actually decreases the market of buyers. Cafes, and I am a rider,too, are over. This is a $3000 exit strategy for your friend, and you will be lucky to find a future buyer. But first, have you even road the bike? Granted it looks cool, but you will find a ride of any distance greater than 30 miles will not be comfortable.
