Awesome deal! Might need some cumulative maintenance, but still incredibly clean bike!
I say test the tyres. Use pressure recommended in manual and on swingarm +2-3psi for your weight. Bring them up to speed gradually and see how they feel. Starting with high-silica rubber compounds in the ‘90s, tyres simply do not degrade like they used to. Even race tyres aren’t affected by heat-cycling like they used to. The 9-yr old factory BT-45 tyres on my street bike works as well as when they were brand-new. Their lap-times are right in-line with new versions. I can drag pegs and kickstand all day long on them.
I like how this guy tests unknown tyres:
