A fellow worker is considering selling HER, yes HER bike, a 76' 550k with 7500 original miles,4-4 pipes, like new condition in appearance and runs fantastic. She is the original owner she purchased it new from dealer when she was 18 and still has original bill of sale. Comes with hard bags, windshield and backrest which she chose as upgrades from dealer, or so she says. It's an incredibly nice bike to see, she's looking to sell it for at the least 4k. Worth it??
