RedOfCourse wroteJust playing around the sprocket cover to find out this...
Any had same problem?
Reasons? Maybe stress or over torquing?
Do you think it is repairable or do I need a new swingarm?
You need another swinging arm.
If you can't find one more local to you, I've a couple that will do the job.
One an original 851 item modified to take a Monster rear hugger and the other a genuine 900 Monster item.
I've also got a Ducati Performance Carbon hugger to suit either of these.
I don't need these anymore as I now run a modified ST4S swinging arm, it's 15mm longer than the OEM one taking the length to 888 Corse spec.
I've modified 3 of these one for myself and the other 2 for a Classic TT Race team.
