The R1 produces more power for many reasons that have little to do with liquid cooling. What they do produces so much waste heat they must liquid cool it so it won't melt.
It's also designed for a different market and mission. Like comparing a taxi to an F1 race car.
But I agree, big inline fours are on the way out with air cooling.
