o.d. of cbr600 itb diameter?
blakep82 - 14/8/14 at 11:18 PM

So, with the prospect of bike carbs not really working due to operating angles, ITBs and efi is fast becoming the way forward
I've got a custom manifold already made for zx9r carbs, the outside of the runners is 45mm, so using 45 I.d coupling rubbers

Can anyone tell me the o.d. of CBR 600 RR itbs, from the 2007-2010 range? I've seen some complete at a good price, and I think they may be the ones for me. Budget is already over budget, and I've not even really started yet anything up to about 60 quid is top whack for me right now for throttle bodies

I've a set of GSXR600 bodies I bought in error, I'm 99% sure they are 45mm od, but in a two pair configuration, I'll measure them up tonight and let you know what the dia and spacing is.

They'll be a fraction of your budget if they are any good to you.

i bought these ones, RR4s so I was told !

they are on my car now like this:







I can measure for you if the above offer isn't better , but can be clearer in layman's terms which bit you need measured?

The inner diameter of the black bit that holds the TBs onto the manifold tube?

I'll get measuring and taking off if you want me to, just let me know.

cheers, Chris

the cbr900s are also 2 pairs, apart from the tube diameter, surely the pair of them are going to have to match the distance between the zx9 manifold tubes? is this going to match up?

suggested that it will.

Here's a couple of pics.

Each outer pair are 70mm centres, the middle 2 are 75mm but could be spaced.

They are 45mm od where they would mount to the manifold.

If they're any good to you £15 posted.

Thank you Pete, as per my u2u I don't think they'll work for me , in case anyone else is interested
