They appear to be offering sprockets that suit stock 525 chains, but with a wide choice of tooth arrangements, and even a handy ratio chart to see how much your combo will change the stock ratio.

Although they are saying stock is 15/43 when I thought it was 15/39?

What model cbr400 as they list quite a few

I've used JT in the past, solid reliable steel sprockets.

I've got one on my NC30. Can't fault it other than it's not gold...

Cheers for the replies. Are you guys using 525 chains on yours? Or 520s?

It's the "standard" replacement sprocket brand that you get with most kits. Good kit, seems to last well enough, certainly a damned sight better than ally sprockets.

nc29 seems to only have 39t option, the nc23 has better choice.

I'm still running a 525 chain.

I run 520 JT sprockets on my race bike. Great product.
