Could any one tell me whether they have used another Brand or found another source of Spherical bearings to replace the listed KTM Bearing repair kit's (R12013- R12012 ) for the Rear mono shock . Looking for upper and lower bearings to be replaced. Checking first before I pull these out and maybe damage them and then not being able to use the beast. Issue here is the time waiting for these to arrive EX KTM. Cheers In advanced.
