BMW R 80RT (1981)

The BMW R 80RT, a tourer designed for the UK market, brings the dream of a grand adventure within reach of a wider audience. With a 800cc engine, this bike packs a punch, delivering a unique riding experience that’s both thrilling and comfortable.

The R 80RT’s engine is the heart of the machine, and its character is unmistakable. It’s a boxer twin that purrs and growls, its power delivery smooth and linear. The bike’s handling is agile and responsive, making it a joy to ride on twisty roads and motorways alike.

Our test bike, fresh from BMW’s Munich HQ, looked every inch the part, its sleek fairing and lightweight construction making it a head-turner. The RT fairing, a classic design that has stood the test of time, provides all the protection and comfort you need for long-distance touring. And with its adjustable screen, you can tailor the riding experience to suit your needs.

As I embarked on a 750-mile journey, I found the bike’s fairing to be a mixed blessing – but one that I grew to appreciate. It’s a bike that’s designed for the long haul, and with its comfortable seat, spacious luggage capacity, and robust engine, it’s the perfect companion for any adventure. With its affordable price tag and impressive capabilities, the BMW R 80RT is a tourer that’s hard to resist, and it’s one that I’m confident will leave a lasting impression on any rider who’s lucky enough to own one.
