been googling what chains fit a Triarm...
getting conflicting info.
some showing a 530 x 108
some showing a 525 x 108

can i use a 530 chain?

why would you? 525 or 520 i reckon. 530 is pretty big, even for a 4/6 conversion if that is what it is for.

525 will be std I reckon

The F2 is listing a 530 pitch chain as standard.
& 400 is 525 as u know.
Just trying to work out which one i will need
I'd feel safer with a chunkier chain.

Trust me Ive been running a DID 525 for years on my 4/6 I think its stock for the hornet.

Did u build your 4/6 waza?

Yup

There are plenty of people "upgrading" to 520 chains on ss 600s and even 1000s will no real issues. No one has lost as arse yet. Just lose some longevity. So a 525 will be absolutely fine even with a 600 motor. My 7r has a 525 as standard and lasts alright on that too
