What chain on my R?
 

Is the chain on my R a 520 or a 525? I'm pretty sure it's a 525 can anyone confirm that?

Yep 525

yep 525 and if buying a replacement Nelly reccomends the Tsubaki Sigma R available from B&C Express ....

The only problem with the Sigma R is that it huuooooge!

Pay the extra money and get the Racing Pro chain. Much better.

Why?

Because it's lighter and will spin up that fraction quicker?

Antonye, stop talking bollx .... x

520 DID erv 2, in gold! As per jhp............

OOh, with a 38 tooth rear!

You've got a 520 pitch on your 999R?

There's so many different pieces of advice around ....

Thinking about fitting a 520 JPM?
