I have transpanted a bmw 650 twin in a puch maxi is it safe to ride?

The maxi's frame will probably be overstressed by the heavier and stronger engine and you might even experience some structural damage over time.
Last but not least, the brakes may not be up to the task of stopping a heavier and faster bike. Tag: I have transpanted a bmw 650 twin in a puch maxi is it safe to ride?
