Long-distance travel comfort and capability are the main design objectives of adventure motorcycles, with large fuel tanks, wind protection, and luggage options. Sometimes used for extended trips and adventure riding, the only off-road-focused machine is the KTM 690 Enduro. Some riders like the versatility of the bike and say it's comfortable enough to do long-haul, while some say it doesn't have the amenities and comfort of a purpose-built adventure tourer. So, how does the 690 Enduro fare against bikes such as the BMW R1250GS or even KTM's own 790 Adventure as far as going the long miles out on the trail? For example, comfort, fuel range, luggage capacity, and touring ability.
