For motorcycle chain, 415 regina chain made in italy seems to be the best bet. If your sprockets can run 410 (bmx) chain then kmc 710 seems stronger than stock 415 by a long shot, and can compare to many 415 chains for it's torque capabilities. I run kmc 710 on my weakest stretch, it's at 50.2:1 (jackshaft output to chainring input), that's around 125 lb/ft of torque before losses, and still over 100 lb/ft after for sure. The chain refused to stretch on a derail and shattered the jackshaft bearings instead, and twisted the jackshaft plate itself. Kmc 710 is strong enough for us all unless you run a pred 212. 410 chain has much less rotational mass than 415, 41 or 420. Less power is used to spin a lighter chain, so more to the ground. Always remember: the less pumping loss you incur, the more power that reaches the ground.
