(Reuters) - South African Brad Binder delivered a sensational home Austrian MotoGP win for his KTM team on Sunday after a late, crazy gamble to stick to slick tyres on a wet and slippery track paid off.

As the rain came down and the top five peeled into the pits at Spielberg's Red Bull Ring to switch to bikes shod with wet tyres, sixth-placed Binder stayed out and hung on in the downpour for three wild laps.
