Dyna Fat Bob's seem to eat bearings no matter the brand. I tried HD, Timken, SKF and All Balls all within 50K miles (including a collapse and wheel damaging experience). I also had to replace the swing arm bearings / bushes twice. I don't think they like commuting in all weathers.50k is excellent mileage on a set of HD bearings. My Fat bob only lasted 18k and wrecked the rear wheel in the process.
Replace for peace of mind and not have to go through the wheel removal process until next set of tyres.
