It's time for a new drivetrain set, any recommendations?
I can get an OEM one for £208, is there anything any better?

DID 50VX is good, not that there was anything wrong with the oem.
Rear sprocket I think is specific to MT so any known brand will do.
Ditto for front except it shares with R1 and FJ so again any good brand.
Do not buy "cheap".
