I can’t speak to the Stelvio but doing any kind of work on the Norge is not simple, just to change the air filter means fully removing the fairing which is a task in itself and the gas tank. Putting the fairing back on is an even more extreme frustration. Everything in there is a very tight fit, getting to the inner spark plugs is a pita.
Does that one have a port hole to get at the dip stick? Otherwise it’s hard to even check the oil. Too much Tupperware for my liking.
If you decide on the Norge inspect all the fairing mounting spots, they can be easily broken or cracked.
