If someone wants to DIY 520 conversion , factory stock is 525 pitch and 116 links, front sprocket is 17, rear is 44.

The front sprocket 17T renthal part # is:
385U-17T-520

The rear sprocket 44T renthal part # is:
210U-520-44P-HA

And a 1000cc+ chain of 116 links.. in this case I got a RK chain:
RK GB520GXW XW-Ring Gold Chain 116 Links (GB520GXW-116)

Driven gold sprockets nuts 10mm X 1.25
Remember blue loctite .

Did you by any chance calculate the weight savings?

Around 1kg...could be more with a ligther 520 chain
