The bottom shock mount on the R30/Dual Sport and 604 all fail where the bush fits into the swingarm, I'm getting some improved units made

Here's a pic of the upgrade, left, and standard, broken WP unit

Anyone who wants one had best get a PM off to me, cost will be 50-60, what ever it costs me, the more the cheaper it'll get

I'm getting a limited number of these upgrades made, including an SKF lip sealed bearing, which should solve this for ever (bearing is extra)

This is not a case of it may happen, it will break, now is your chance to sort it permanently before it breaks

Save your CCM!
