The torque quoted by CSC is very large. The torque quoted for the very similar, virtually identical, Suzuki sprocket is also large. The Suzuki torque is quoted as large as 100 foot-pounds.

However, as you have seen, after you ride the bike a few miles, the nut gets very loose, and is only retained by the safety washer. That is why it is so important not to bend the tabs on the safety washer more than twice.

I merely tighten the sprocket nut as hard as I can with a normal socket wrench. I don't use either a breaker bar, or a torque wrench, since the nut is going to loosen anyway. Then I make sure I attach the locking washer securely. No matter how hard you tighten the nut, it is going to loosen to a hand tight fitment. Therefore, the locking washer is crucial for keeping the nut on the sprocket.
