There is no such thing to "no maintance" on any final drive. Not chain, belt, or shaft. BUt they are in order from most to least amount of maintance.
I would have no problems running the 520 on a liter. I ran one on my 9R. Just get a good X-ring chain (DiD) and good sprockets. Then get an alignment tool and properly align the sprockets.
