Ural better not be a dirty word here! Carbs, bearings, gears, electrics are all outsourced nowadays, so they're much improved from the bad old days (pre 2005) No magic with the splines though. The wheel hubs are splined and are known to grind down about 40,000km. In fact, the 2014's are redesigned with replaceable splines, previous year you replace the whole wheel. Drive shaft splines are not too bad, but most of these bikes don't accumulate that many miles. The 4 on ebay now (a 2013, 2001, 2010, & 1986) have 971 ,4200, 2450 and 11 miles respectively! Transmission, engine, and rear end failures sort of make spline failure small potatoes in the maintenance of these beasts. That said I love the crap out of mine, would sell my trusty K except the Ural is not something to take on long trips or much highway. I ride all winter now and it's great in snow. The looks I get are priceless.
