If it barks and wags its tail it's probably a dog
To be serious - No, in strict age terms of course a 2005 bike cannot be a classic BUT as it is a bike with a design thats 60 years old, needs to be ridden with all the skills needed of a 60 year old....and gives all the satisfaction of a bike of that era then , yes it's a "classic".
For me the facts are that
1). Even living in a fairly remote part of the country, I can get a full spares service within 36 hours to my door.
2). Such is the support for the marque that I choose several avenues of modification kit, from Trials to Vintage look and pretend Cafe racer to really hotted track bike.............. all with a massive Owners Club backing.
3). Spares are
really cheap - and for a pensioner that matters.
