Small bores tend to be chain driven for cost and weight reasons.

I run #420 "O" ring chains on my bikes and they're virtually maintenance free. There are folks who say running an "O" ring chain hurts small bore bikes' performance and it may very well do this although without a dyno I can't see any difference. Not having to deal with constantly lubing a chain is wonderful.
