I wouldn't be shocked (pun intended) by an electric motorbike that can do 160 kph, but the 10 minute charge rate would be ambitious. From their figures, that's for an 80% charge for a 6.4 kWh battery pack, or 5.12 kWh delivered. Assuming perfect charge efficiency, that's a power rate of 30.7 kW. The C-rate of this battery pack would have to be 30.7/5.12 = 6C.
For comparison, a Hyundai Ioniq 5 automobile has a 58 kWh battery pack and (apparently briefly) supports 350 kW DCFC. The best such battery pack would have a C-rate of 6.03C, but most likely is lower because this rate would imply a charge time of 10 minutes, not the 18 minutes advertised by Hyundai.
So if a major automaker's new(est?) EV is only marginally able to achieve the charge rate of 6C, it doesn't seem likely that a motorbike manufacturer will be able to beat this, let alone have a comparable average charge rate. The same analysis for some of the other electric motorbikes linked from the article have lower peak or average C-rates, and those motorbikes already exist.
TL;DR: charging is hard. Apply heavy skepticism.
