Is it in the Anniversary Black and Gold ? 105th Anniversary special they were called
Mechanically they are well bulletproof if serviced every 4000 K's.
I had one from new in 2008 , loved that bike , did 66,000 K's on it with no dramas
The price you have been asked for it is nothing special in today's market , bike would have cost him $32K back in the day
The market for used Harleys has changed forever since then , so $17K may be a wee bit strong
PS I'm 58 shortly and intend to keep riding for as long as possible. My oldest riding mate is 86 , just converted his Harley to a trike 3 years ago !
