The WP shock suspension on my CCM R30 (2004) is showing a crack on the lower link. Can anyone advise me on what to do? See photos below. Thanks.
the only thing that would be safe would be to replace it but you might be able to get it welded up
A WP suspension specialist should be able to replace that bit. Probably best done as part of a servicec rebuild.
I think the rebuild is the best option . Looking online a replacment of decent quality will cost a pretty penny Hopefully some supermoto experts in here may point you to a rebuilder .
might be cheaper to look out for a low mile ccm being broken for parts than fix and service that one
Lucky to have found one already. Phew ! Thanks guys.
Know you got a replacement but see this on smf and might be handy for the next time
