BMW updates its GS Adventure for 2014 with the water Boxer and new chassis that debuted on the 2013 base model GS.

The Beemer’s ABS on the GS/GSA Enduro settings simply works.

The GS Adventure ups the comfort factor with its larger windscreen and we particularly appreciated the well-placed wind deflectors at the top of the fairing, which do a fantastic job of reducing buffeting.

The GSA's estimated range is a staggering 430 miles. At the end of our 200-mile day, the fuel gauge had just barely dropped one bar below half full.

The BMW electronics package really does transform the bike depending on function.

The GSA is more deliberate to change direction and not as light on its toes as the standard GS. Still it gets along just fine and doesn’t feel twitchy despite its steeper rake.

The street modes and ESA settings all function like the standard GS.

The GSA creeps and crawls quite well and I had a no issues during our near 100 miles of dirt in Arizona.

The GS Adventure's heavier flywheel mass makes a noticeable difference, particularly off-road.

The GSA likes to play out in the dirt, or the wet in this case.

For 2014 BMW migrates all of its 2013 GS updates onto the GSA.

Despite its heft the Beemer feels balanced and glides along without stumbling.

The list of standard off-road friendly hardware for the GSA includes hand guards, adjustable/reinforced brake lever and wider enduro-style footpegs.

The Adventure’s brawny stature, teamed with knobbies and various off-road farkle, make for a serious-looking mount.

The most distinguishable visible alteration to the Adventure package is the large crash bars that encase the fairing and engine.

In the GSA the new Boxer makes good use of its extra 15 horsepower. It’s stronger from top to bottom, with engineers evening out the midrange and gaining a nice surge up top.

In the engine department, the Boxer Twin sources a two-pound heavier crankshaft, with 20% more inertia and, correspondingly, an increased flywheel effect.

The 2014 GS Adventure proves the Beemer can still pull its weight when the pavement ends.
