BMW motorcycles have traditionally been known for their boxer engines, featuring horizontally opposed cylinders and lots of torque. Now BMW is looking to inject some of their automotive DNA into their motorcycle program by developing an Inline -6 cylinder engine for their K Series cruiser bikes.
Displacing 1,649cc and putting out 158 horsepower and 129 lb-ft of torque, the engine should be enough to propel the big K1600 around your favorite cruising spots, and with 71% of the torque available by 1,800 rpm, it should do well in city traffic too.
Perhaps the most interesting part of this story is that BMW’s car division is actively trying to downsize their engine range, with four and even three cylinder engines being touted for their compact passenger cars. We understand that high-revving, air-cooled bike engines are generally unsuited for automobiles, but the both exercises seem somewhat counter-intuitive.
