My BMW K1200S is dry sumped but most are wet sumped. Because bikes lean into a corner oil surge through is much less of an issue (BMW did it to mine for packaging reasons). A lot of kit car companies sell dry sump or accusump kits for bike engined kit cars so I guess it's an issue.
As for reliability, my ZXR400 blew up fairly spectacularly every 14,000 miles without fail despite mostly being used in traffic commuting. My K1200S breaks down a lot (it's been broke for the last year) but that has done 80,000+ miles and the engine internals are perfect barring the damage caused by BMW mechanic not knowing how to use a torque wrench and threadlock properly.
