What you've got there is a Chinese copy of a Taiwanese OKO hence why it was cheap. Haven't heard anything positive regarding these unlike the genuine oko which gets good reviews. .how did it go
IMHO there are plenty of mechanical parts available. Probably cosmetic parts are getting thin on the ground but other than that most common parts still available readily. Moreover the 02 was in that era before the bikes became light enough to be fragile. It's a hearty bike.
One thing the 02 did suffer from was a weakness in the alloy welding for the rear brake caliper stop pin on the swingarm. Check that is not broken. It was resolved on the 03 model. You'll also find any bike that age may have a heavily corroded front rim if it's been left wet (which most are). Hard to check without removing front tyre. Rear shock is likely worn out as may be the fork bushes and sliders. The 02 isn't affected by waterpump corrosion as it had an aluminium casing.
But yeah, it's now 14yrs old...
If you put the 16 Scorpa and Sherco side by side there are some significant differences. Marzocchi 40mm forks v Tech 39mm forks, frame has different extrusions around radiator and headstock, cable routing is different, tank is different, Michelin X11 v Dunlop D803GP and the list goes on
