How so don’t give Qads with performance

Moin Moin I’m looking for a really nice ATV while browsing but I noticed that there are hardly any over 50 Ps there is that with AHK which wouldn’t be the problem but then it’s at 60 Ps end. That pulls with a heavy ATV with 850 CCM or more no chicken from the nest. Strangely, identical models with the Americans have more power in part 20 Ps. If the things here in Germany have to be castrated again or why is that so. Or just asked ATV here in Germany n e Power limit???? Please answer Thank you very much in advance MfG Casi
