Chasing a modest target of 126, the Royal Challengers romped with 6.5 overs to spare.
This was Bangalore's fifth win on the trot and it has taken their points tally to 13 from ten matches.
A victory against Rajasthan Royals at Jaipur on May 11 would put them in strong contention for a place in the top-four.
The ignominious defeat, on the other hand, has scuttled Kochi Tusker's hopes of advancing to the knock-out stage as they have just ten points from eleven games.
