ER-5 mileage – was it turned?

Hi guys! I’m about to buy a motorcycle in the near future. Very probably it will be a Kawa ER-5. I now have an offer for one of ’97 with a mileage of 3000 km. For approx. 1900 EUR it should go over the table of the dealer. Now I have a little fear that something is wrong with the mileage. The only previous owner should have “only driven very rarely” and “kaum time to drive”. I expect no clairvoyance, sonde rn only your opinion Would you possibly have an idea how I can see if everything is fine with the machine? Mainly because of the mileage etc. Thanks to you already.
