Found these in a box of NC30 spares, I assume they are steering head bearings, they are marked 32907-2

Can anyone confirm?

Can't confirm NC30 (yet), however I have turned them up as races for a Ducati 748....

Hmm ok so these seem to be 55x35x15mm bearings while the NC30 I think are 55x35x14.5mm?

Ok so I got my info from this site:

http://www.bikersoracle.com/vfr/forum/a ... 00065.html

Which states that RC30 / ZXR400 & ZXR750 use the same bearings and the kwakisaki part number is SSK907

Pyramid parts website list that bearing as being 55x35x15 so we have a winner and these will fit the NC30

Thanks!

All the NC30 ones I've turned up have an NTN part number on them, and it's nothing like the number yours have. There's a page with shedloads of sizes for bikes listed, but the formatting is a bit jumbled and it's in German! lol

How does this grab you?

Cheers yeah thing that just confirms it then think this should fit an NC30, good news as saves me a few quid buying a set.

The box of bits I got it in has loads of parts and some of them like this have no part numbers
