I replaced the swingarm linkage bearings last year but they are as bad as the ones I took out now. So what MFR makes the bearings for Ducati? No point buying more of the same, but no point asking Ducati because they don't list spares for the 906.

The old ones I had removed were from INA.

sure, see 750FAQs for alternatives

INA are extremely high quality bearings...in fact INA are about the ONLY high quality needle / cylindrical roller bearing company I know of...

I strongly suggest the HIGHEST quality lubricant for the swing arm bearings; they are subject to fretting corrosion and minor galvanic current. it might be a case for something like Lanotec grease.

Its ALSO very important to put very good quality seals to swingarm system, not only bearings. There are many seals also, what are against shit going inside bearings..... remembering, that 6 of one size and 2 another size. High pressure water washer is one of worst things to such bearings..... same with wheel bearings!!!!! I never use such machine with washing my Ducatis, no matter i have such! Only for car cleaning.... from mud!
