The roads BMW sent us down put the bikes' aluminum beam frame, traditional telescopic fork and single-sided swingarm combination through the paces, especially the torn-to-shreds Saddle Road that straddles the Big Island's 13,796-foot, volcanic Mauna Kea. Again, the F800 models score high for being mild-mannered-very stable yet compliant enough to keep us from skittering into the lava fields, with well-damped steering that's both precise and constant. The toothed rubber belt runs smoothly, while the six-speed gearbox offers quick, satisfying shifts save for the occasional, irritating false neutral. The S-model is said to weigh 401 pounds dry, and the stock accoutrements on the ST add only 11 pounds- totally manageable, especially with the under-seat fuel capsule lowering the bike's CG. Seat height is also friendly at 32.3 inches, with the saddle sculpted to be especially narrow in the front, which encourages a straighter leg and, therefore, more boot on the ground. Newbies or shorter riders can opt for a no-charge replacement saddle that drops seat height to 31.1 inches; or a replacement shock kit that further lowers it to 29.9 inches.
