C90 z2 zz lower pivot arms 12mm spindle model

Post by spen001 » Wed Sep 04, 2019 9:06 am

I have a C90 which D Silver advised was a C90zz 1977 model, I purchased this barn find to restore. Most parts are easy enough to find, others not so. The front fork lower pivot arms are 12mm spindle size, after lengthy searches are not available in the UK.
Any pointers would be gratefully accepted please?

Think you can use the later 10mm ones and just drill them out to 12mm as they fit the same.

If you still have the originals just fit a replacement bush kit.
Plenty available on ebay etc not as good as original spec but usable.

As steveST100 says links with 10mm holes can be drilled out to 12mm without any problem.I did it on my 1970 C90 when I fitted a 1984 set of forks.Honda didn't bother to change the link forging when they decreased the size of the spindle,presumably to save money,so there's no loss of strength involved.
