What about the F650GS twin cylinder bike?

Available with either a low seat free of charge or a low chassis version (low seat & shorter suspension both ends) for a small cost (£98 in the UK). Seat heights as follows:

Standard chassis & seat: 820mm
Standard chassis & low seat: 790mm
Low Chassis option: 765mm

16 litre underseat fuel tank keeps the CoG low, they're economical (20km+ per litre easy unless you're riding it hard) and 6,000 miles / 10,000km service intervals. Servicing is cheap, the 6k in the UK is about £120 & the 12k under £200, the valves need checking every 12k.

19" front wheel allows fitment of knobblies if needed, 71bhp & decent midrange power allows for reasonable overtaking from 70mph which some singles will struggle with, especially when loaded up.

There is not another similar spec bike capable of tackling gravel roads & some offroad tracks that's got a comparable seat height. If you buy one, make sure you get the On Board Computer (gives you fuel & temp gauges, gear indicator, average speed, average & instant MPG, ambient temp & mileage to go until you run out of fuel). Without it, you only get a clock, odometer & two trips. Factory centre stand is cheaper than having the dealer reftrofit it later.

Plenty of BMW & aftermarket luggage & crash protection options available.
