Any idea the ID the of clamp required to fit over the lower collector joints on the NC30 please. I've just had mine repaired and need to reassamble, being picky i'd rather not use the washing machine jubilee clips that were on the bike previously. I'm sure I could get some nice quality stainless ones for a better price than the Honda items!

the collector joint is 45mm OD for reference

Is this what you're after?

yes, but for the collector joints, that ones too big for a stock collector. Thanks for the link.

If you're talking about the ones to join the front headers to the rear half, I used these:
