I have a Cusco in the orange 818. I am pulling it out. I will not be putting one in the new 818 either. Tony at F5R said they are not running LSD anymore either. Not sure if it is weight, placement or axle geometry but it nearly binds on slow turns. Jim rode in the orange 818 and confirmed the LSD was binding and advised not to drive it till removed as he said if it locks up on the highway, it won't be pretty.
