Just wondering what RPM the stock crankshaft can handle without the bearings coming loose or breaking.

Thanks

after 10,000 rpm all bests are off on most stock cranks

I've been riding on 10,000 on a straight and close to 11,000 downhill... bad idea?

one of the reasons they restrict the TGB's  is
to keep you from going over 10,000rpm because that
will lunch the crank
 
so is it a bad idea ?  it will shorten the life of your scooter
