BMW R90S: The Boxer that broke the Mould...

“The R90S didn’t just ride better—it looked fast sitting still. That fairing and Daytona Orange paint were pure attitude.”— Classic Bike Magazine, 2004

In the pantheon of iconic motorcycles, few bikes command respect quite like the BMW R90S. Introduced in 1973, it was more than just a new model—it was a bold statement. For decades, BMW had been known for building durable, upright touring motorcycles, not fire-breathing sport bikes. But with Japanese manufacturers like Honda and Kawasaki rapidly changing the game, BMW needed a performance machine that could excite a new generation of riders. The R90S was the answer.

Designed by Hans A. Muth, who later created the R100RS and Suzuki Katana, the R90S introduced several firsts for BMW. Most notably, it was the first BMW production motorcycle to feature a wind-tunnel-tested bikini fairing. It also came in dramatic hand-finished paint schemes like Smoke Black and the unforgettable Daytona Orange, each shaded by hand for a slightly unique look.

Under the tank, the R90S was powered by an 898cc air-cooled boxer twin, producing 67 HP (49kW) and capable of reaching 125 mph (200 km/h). Dual front disc brakes and a 5-speed transmission gave it modern handling and serious touring credentials.

The R90S quickly proved it wasn’t just a pretty face. In 1976, it won the inaugural AMA Superbike Championship, piloted by Reg Pridmore. That victory helped redefine BMW’s image in North America and proved that the flat-twin boxer engine still had racing pedigree.

Despite its short production run from 1973 to 1976, the R90S left a lasting impact. It’s now considered one of the most collectible BMW motorcycles ever produced and a turning point in the brand’s evolution from conservative tourers to serious sport-touring innovators.
