You have a 1997 Yamaha XVS650 Custom.
Standard colour for the 97 models. There is also a pale blue version and a red & silver version (different years, I believe).
There is really only the Custom - model XVS650 and the Classic - model XVS650A
There are variants A, B, C, J, Q etc but these are just very slight revisions. Just about everything is still interchangable between variants. It's only whether you have a Custom or Classic that makes any difference.
The bike has customised pipes, backrest, luggage rack, bar grips, mirrors, tax disc holder and footpegs.
Take the other keys off your keyring, otherwise they'll swing back and forth as you ride and scratch your tank paintwork to buggery.
