D.I.D 525 ZVM-X X-ring
This set of DID chain and jt sprockets, always run first class for me. In my old Bandit 650 k7 I run aprox 50000 kms with this set, as your riding style, daily commuting and some large travels.
RK would be another option, but, in DID brand the X-ring series is very reliable.
It's my personal experience.
