Intera 2013 clean

Intera 2013, 2000 engine, personal use, first owner, clean and solid chassis. I want to sell the engine, spare parts, belts; condition is that the engine is original from the agency, not tampered with, sounds good except for a knock in the big end bearing, which I fixed seven years ago, front bumper damaged, mileage 590, oil does not exceed 4000, selling because I have another motorcycle
