Buying a FS650E 2007 model.

Hello everyone. I have had my eyes on a FS650E 2007 model that is for sale near me. The seller has said that the engine got an overhaul 10 hours ago. and has a total of 190 hours under its belt. The bike is only going to be used on the road and maybe some offroad. does this bike have any weaknesses i should know about? since it is a pretty old bike i have my concerns. the bike itself looks really good and it looks like it has been well maintained. only had experience with KTM and Husqvarna but as what i understand is that the brands are pretty much the same. is the engine for this model bulletproof or is it ****? if i could get any information on the service perspective also

Thank you for every answer.

thanks for the answer. do you happen to know where i can buy this ORANGEBERG kit? Do you happen to know the service interval or perhaps the overhaul interval? The internet on the ship i am onboard doesnt let me download the manual for it.
