Sound reasonable to me.
The airfilter should be new, and the bike has fuel injection. It has been used
mainly for commuting, and very few short trips (< 5 miles).
It has 55 000 km. If most of it was for commuting, with each trip being 40 km,
it means that it has probably been started less than 1500 times.
Rings and cylinders may be worn. Since it never received a valve adjustment, it might improve by having that done. I don't know..
