Potent appearance and casual gentleman style in a classic design characterize the BMW R20, the new concept presented by BMW Motorrad at the Concorso d’Eleganza in Villa d’Este.
Focused on the Big Boxer engine, the clearly visible fuel tank looks like a sculpture, the rear end is reduced to the essentials to emphasize the simple lines and power of the motorcycle.
The double-cradle frame is made of chrome-molybdenum steel tubes to form the backbone of the motorcycle. With a black 17×6.25 inch disc wheel at the rear, mounted with a 200/55 size tire, and a 17-inch wheel with black spokes and a 120/70 size tire at the front, the BMW R20 concept combines tradition and modernity.
The tested and proven BMW Paralever was carried out in a new two-arm variant, where the swingarm is made of chrome-molybdenum steel and the Paralever shock absorber is made of aluminum.
Kinematics was designed to fully balance the drive torque. The two milled aluminum rear axle supports are another high-quality detail. The exposed driveshaft, conceptually adopted from the R18 – the visual highlight of the well-known R 18 models – has been shortened to be integrated into the roadster’s architecture. As suspension components, the fully adjustable Öhlins Blackline components work front and rear. The vehicle’s basic geometry features a steering angle of 62.5° and a wheelbase of 1550 mm. Radially mounted ISR brake calipers front and rear take care of deceleration, with six pistons at the front and four pistons per caliper at the rear.
In addition, the 2-in-2 exhaust system provides the distinctive sound character and perfectly complements the design.
The centerpiece of the BMW R20 concept remains the air- and oil-cooled Big Boxer engine, now with a displacement of 2,000 cc. New cylinder head covers, a new belt cover, and a new oil cooler have been developed for the conceptual bike, so that the oil tubes can be partially hidden: The eye follows the path of the air as it flows through the open intake funnels to the throttle bodies and cylinders, before escaping through the open exhaust system and megaphone-designed exhaust pipes, creating the typical Big Boxer sound.
