Hi all I was wondering if someone apart from Honda has serial numbers for the needle and sealed bearings on the swingarm.

Have a look here http://akhara.com/nc30/nc30parts/files/40.htm for the sizes of bearing/dust seals.

I got Honda parts, not overly expensive imo, the above link gives bearing size but not needle bearing.
Put the part number into David Silver Spares and get an idea of price http://www.davidsilverspares.co.uk/part ... ber_18418/

Hope this helps

Thanks for the info got off flea bay a guy called bearing options less than £20 all in for the 3 bearings.
