No compression

I have a RoadStar 1700 from 2005 and the mechanic tells me that it has no compression. Someone knows if this can be caused by a defective decompression selenoid. Or if this is a defect of this motorcycle?

How did he determine this? Does the bike start easily and is it ride-able? Yes, it is possible this could happen but I wouldn't bet on it. Usually the opposite occurs. Have a compression test done by another mechanic I'd also do a leak down test. The solenoids do fail. Usually because moisture makes the connections go bad in the solenoid.
