Hi folks - does anyone have or could measure the sleeve and bolt sizes of the Yamaha R6 mono shock bottom mounting arrangement which is one of the recommended suspension upgrades on this forum. I have a good machine shop near me and wish to make these rather than pay a Yam dealer over £40 for the parts. Many thanks

I should be receiving mine in the mail today. I'll get it measured up asap.

Here is a link to my shock upgrade. Sorry, I took a lot of pics but did not document the measurements before I put it all together. I'm sure I must have look up the collar and bolt size on a Yamaha parts list found on the web.

If it helps the one in my pics with the thinner collar wall is the yamaha one.

I got my r6 shock today but it was missing the sleeve. Will be a couple more days on that little guy.

I got pics uploaded. Hope these help.
