The Million Mile Engine They Stopped Building (Because It Was TOO Good)

In this video, we explore the rise, engineering brilliance, and eventual retirement of the BMW K-Series 'Flying Brick'—an engine that redefined motorcycle longevity. From its roots as a Peugeot car-engine prototype to its 26-year production run, we break down why this horizontal inline-four became a legend for reliability.

Key topics covered:
The 1970s crisis: How Japanese manufacturers nearly ended BMW's motorcycle division.
Engineering the Brick: The 'sideways' logic of the Compact Drive System and Nikasil-coated cylinders.
The K75 vs. K100: Why the three-cylinder version is considered one of the smoothest engines ever built.
