...I see it's belt final drive. Personally, I've never been a fan of a belt final drive, especially if belt replacement requires major disassembly of the engine (as in HD). I've always felt that a belt final drive makes a bike look like a Whizzer (I'm giving my age away). I prefer a drive shaft or even an 'O' or 'X' ring chain. Modern, sealed lubricant chain assemblies are clean and reliable and drive shafts last forever (well, almost all the time, the R3 is an exception). If the drive cogs can be accessed with major disassembly, that would be a plus. I've seen more than one belt drive destroy itself from ingestion of a small stone between the cog and belt...
