Look how she runs.
There is a *slight* low-speed surge, BUT
1) the Adventure model has a significantly shorter first gear than the standard 1150GS (and the rest of the R-bikes, as well) so even when my road speed is realy slow, I am turning the engine quickly enough to keep out of surge territory. I other words, I have to be going about 2-6mph to notice any surge on my bike. Even then it has to be steady speed; accelerating through the low-speed stuff produces no Even at 6-7mph it smoothes out. Literally, the only time it surfaces is when I am crawling at walking pace in bumper-to-bumoer traffic, which I've since learned to avoid by learning side roads.
2) My dealer has two of about 28 BMW Certified Master Techs in North America, and a good wrench can dial it in really well. They have told me not to fiddle with it until the bike is entirely broken in, which is apparently around the 12-15k mile mark on these R-bikes.
But how often to I stay at that low speed, really? The shorter first gear (shorter sixth, too) are for more tractability off-road, since the Adventure is the really "butch"version of the bike.
In short, she runs great at 4k miles in a month-and-a-half. Wouldn't quite give my left one for this bike, but I didn't have to. Now I have this crazy idea to pick up a used F650 and motard it for more twisty-fun-day stuff. Of course, I also hve an idea to cafe the heck out of a two-year-old R1200C. But this Adventure is really all teh bike I could *need.*
