Twenty, I run premium in my '14 DL1K because that is what's called for in 2 versions: The decal on the left side of the instrument cluster says "Use Premium fuel...", while the owner's manual says "Requires premium fuel..." and at no time to use anything other than Premium. During a conversation with the regional Suzuki service rep at the Chicago bike show 2 years ago he volunteered--with no prompting or question by me-- that although Premium is recommended, there is no problem using regular.
The dealerships send their bikes out with regular, and those(car) dealerships that have on-site gas pumps( like the ones I worked at) always had regular, not Premium. The price difference between the 2 isnt enough to dissuade me from using what's recommended, and if I can't afford the recommended fuel I shouldnt even own a motorcycle in the 1st place.
As for reliability, I dont have enough miles on my Vstrom to judge it's reliability one way of another EXCEPT for 3 factors: 1) It starts immediately and with no driveabilty issues no matter how long it sits. 2) It runs the same way--excellent-- every single ride. Not so much as a sneeze, cough, or fart. Just smooth, steady power at any time. 3) Stuck in a 1.5 hour traffic jam in I-57 on the way back from Deals Gap, 105F degrees(or higher) inching along , ambient temp gauge reading 122F, and the fan never came on nor did the engine temp gauge go over it's normal 3-bar middle reading. Traffic opened up, no engine knock on acceleration, no flat spots, no nothing--just business as usual. I was mightily impressed. Still am.
