That was true until last week when the first pics of the Jesse S10 bags started showing up. Same width as the OEM, a lot more capacity. I'm sure both racks and bags will be stronger too. No pricing yet but most likely only a little more expensive than the OEM (depending on how much discount you're getting from your dealer of course).
Actually only now did I read the release properly - they have THREE options - 105 litres/35.5" (same width as stock but holding an extra 41 litres), 90l/33.5 (these will be mine I think - 2" narrower than stock but holding 25 litres more) and 112 litres/38".
