BMW has upgraded its middleweight parallel twin-cylinder line with a larger version of the engine from the F 850 GS, which brings more character and smoothness to the new F 900 R (shown) and F 900 XR.

Since the launch of the BMW F 800 model family with the F 800 S and F 800 ST in 2006, these middleweight, parallel twin-powered motorcycles have been offered in a wide variety of models as lower-priced alternatives to BMW?s larger bikes. As with the R 1200 boxer twins, the most popular parallel twins have been the F 800 GS and GSA adventure bikes, with the more street-oriented F 650 GS/F 700 GS close behind. No surprise, really, since adventure and ADV-styled bikes have done well for some time now.

Conversely the F 800 ST and later GT sport-touring versions were short-lived, leaving the F 800 R streetfighter introduced in 2009 as the sole non-GS model in the lineup as of 2019. No doubt the bike?s entry-level price and the showmanship of four-time world-champion freestyle rider Christian Pfeiffer — who helped develop the naked bike he spun, slid and nose wheelied to victory — extended the F 800 R?s longevity.
