The Russian brake shoes are beefy, with a capital B. The lining is around 12mm thick. I don't know if I'll ever need to replace them. Getting the shoes initially dialed in is what takes time. A lot of different adjustments required. Once set, it's just turning a nut just like a drum brake bike.

Front brake is a four piston Brembo and very powerful. Stops a half ton quite well and I imagine wear on the pads and rotor is dependent on rear brake adjustment. The newer bikes have disks on all three corners and are a different animal.

Bearings are a crapshoot. When it does come time to replace one, go with something like FAG, SKF, Nichi, or Timkin. Same with seals.

U-joints are dependent on lubrication. I just replaced the original Russian ones in the sidecar axle that had no zerks. I replaced them with zerked Moog joints that should outlast me. The propshaft joint is Ural specific and now comes with a grease zerk. There is no room to use a standard grease gun, though, if the zerk is in the cross, so you need to use a needle. The newest ones have a zerk on one of the cups.

The clutch would depend on how well it's adjusted and rider skill. It's a dry double disk and big.

The last thing I can think of is the 'donut' between the tranny and the propshaft. It's a big hunk o' hard rubber with a metal band around it that acts as the front u-joint. Also Ural specific and it's longevity depends on how well the final drive and propshaft are aligned.
