Hi, Jan.

Yeah, the sprag I've got in mind is plenty stout for the application:

Stieber ALF2D2 30-500
ALF2D2 & ALF4D2 Types | Self-Contained Freewheels | Stieber Clutch
http://www.altraliterature.com/pdfs/...A4_AL-F4D2.pdf

4100 RPM overrunning speed (which equates to ~240 MPH on this scooter)
500 Nm (369 lb ft) of torque (I think the scooter makes about 15 lb ft)
Supported by two 160 series roller bearings
About 560 Kg (1235 pounds) combined carrying capacity on the two roller bearings
Oil filled and lubricated

So it'll be pretty much bulletproof in this application. I'll be replacing the 160 series roller bearings in the sprag with hybric ceramic bearings, as well, to make it roll just that little bit easier.
