BMW R 100/7 (1976-77)

The BMW R 100/7: a workhorse of the Bavarian Motor Works that defies expectations. For years, it’s been the favorite of tourists and working-class riders alike, effortlessly navigating Superslab and crowded city streets alike. We recently had the chance to revisit the R 100/7, and were struck by its newfound vitality.

This is not the sluggish, matronly machine we’d imagined, but rather a seasoned veteran with a deep understanding of the world. Displacing 980cc and weighing 474 pounds, the R 100/7 is a force to be reckoned with, its 2 enormous pistons pumping out a rhythmic beat that’s as soothing as it is intense.

As the engine settles into a smooth idle, a subtle vibration hums through the bars, a reminder of the big twin’s presence. A new set of grips would certainly help to smooth out the ride, but as it stands, the R 100/7 is an exhilarating companion that demands to be ridden hard and often.

The BMW R 100/7 is a true classic, a testament to the enduring appeal of a well-crafted motorcycle that rewards its rider with a unique blend of power, poise, and personality.
