Reviews
" Always left with the impression of a lively engine, which develops great temperament thanks to a shorter translation of the top three courses, even at higher speeds. Best example: Who wants to know partout how fast the R runs, needs for on the highway is not much contact. Jiffy turns the 798er in the red zone and on to the limiter, which employs 220 at Speedo. "
"Given the performance objectively offered the Twin plays loose in the league sporting multi-cylinder with, and with enthusiasm, character and remarkable soundscape - in the low speed range sonorous humming, from the central region, where he to increase considerably nimble on tours, vigorously from the airbox pounding. "
" The first gear has a fairly long, the clutch cable is not completely free of malice dosed with which we have already mentioned, the full in this first drive report brought to light, getting used to details. Elegant swingarm, final drive chain instead of belt such as the Sisters F 800 S, F 800 ST. [ ... ] The chassis is rock solid up in sporty road tempos. Playful can not call handling, as is the 180 rear tire limiting factor. 25 years ago BMWs were contemptuously called rubber cows because of its soft suspension tuning. Long since past. The F800 R is a sporty yet firm, perhaps a little too sporty for bad side streets. "
