We have a 2021 650 Vstrom, brilliant machine and very underrated in my opinion, coming from two ST1300's, we are two up all the time, and we are very near it's maximum weight, no complaints whatsoever, with performance, handling and comfort, [now I have had the seat re-done], as for the NC 750X, three of my mates have them and they can barely keep up with me two up and there solo, also I wouldn't recommend the NC750 for two up, only one disc at the front and No preload at the rear, not good for two up, I discounted it straight away, when looking round before I bought the Vstrom and I have had Honda's for 45 years, never looked back, love it
