Good summary here by JMo after <4k miles. (Rally Raid conversion so suspension obviously gets a pass.)

Besides many good points (like vibes pass after 6700rpm - never got that high myself) she also mentions the too narrow front pegs (for standing) plus prematurely worn out cush-drive rubbers, like the the old XTZ660. Never had any probs (that weren't of my own making) with mine on the short trip I did, but I always thought that the Tenere was another bike which looked great, capitalised on a legendary reputation/brand, but was heavy and cheaply put together underneath. People still managed big trips with the usual minor probs.

Also, far from unique to the 310, but as with all these highly tuned, small-engined bikes (I've had or run a few in recent years), the fuel consumption isn't impressive when you think of what you lose in terms of comfort, easy overtaking, etc. What JMo recorded below (UKmpg added) is worse than my CB500X (av: 74; best: 93.5; worse; 57) and maybe the 500X she ran on the TAT 2015.

3. The fuel economy is good. Initially while keeping the bike under 60mph, I got as high as 67US [80.5UK] mpg, and typically 62 [74.5] mpg was my average according to the dash display. However, it does start to increase once the speed rises - 70mph or thereabouts sees it drop to 57 [68.5] mpg (and as low as 48-50 [59] mpg in a head wind), while pushing 75-80mph means I didn't get over 50 [60] mpg, and as low as 39 [47] mpg into that strong headwind and uphill over Tehachapi [Pass; famous wind farm] …

With the 310GS I see some convincing themselves it's a mini GS1200 so must be suited to travel biking, rather than a small-engined bike with the big GS look.
As Fern said, it's 'made for people that want to dip their toe into the BMW brand'. Nothing wrong with that and a smart move by BMW. Great for nipping about and for Rookie Riders; not convinced it's my kind of travel bike (any more than a 1200GS, tbh) because for me the whole point of putting up with a '250's' limitations on the street is light weight and agility off road.
