Likely why it was parked to begin with as much as needing a ring job. I would just make a crosser out of it as this is the cheaper way to go and follows the original intent of the bike anyway.
Have you ridden one? I raced and trailrode one for years,they are as smooth as could be desired.
And fast enough.
KTM sells 7 different thickness base gaskets to tune the engine for what you want to do with it. I dont know if those are still available but I detuned my 495 a little with thicker base gaskets.

I also had a 77.5 250 GP model for years,flattracked it,trail rode it,MX'd it,then scrambles raced it,then rode some enduros with the same bike.
It never broke and it won some races.
Some bikes around at times
