Street. Style. Stunt. The BMW Concept Stunt G310

At South America’s largest motorcycle show, BMW Motorrad introduced the BMW Concept Stunt G310. It’s a completely new side for BMW Motorrad: an uncompromising interpretation of an aggressive and agile stunt bike with a single-cylinder engine.

Ideally you need a compact, agile bike which is also stable and robust at the same time. You have to achieve the ideal balance between aggressiveness and control,” explains Chris Pfeiffer.

The BMW Concept Stunt G310 combines all these qualities and makes clear at first sight: the newly developed single-cylinder engine allows for very compact proportions thanks to its innovative concept. The special feature is the cylinder which is inclined towards the rear and the cylinder head which is rotated by 180 degrees. This permits optimum placement of the engine in the motorcycle and a short wheelbase in spite of the long swingarm thereby making the motorcycle very agile. The low-slung front and the raised tail section promise fast and nimble changes of direction as well as dynamic riding. By shifting the intake area towards the front while also moving the exhaust system towards the rear it was possible to place the rear silencer in an upright standing position underneath the seat between engine and spring strut. In this way the silencer is optimally protected and does not limit the stunt rider’s freedom of movement. Even though you may hardly see it, you will not miss hearing it. Once started, the sound of the BMW Concept Stunt G310 is sure to attract attention.

The emotional side view of the Concept Bike is characterized by the powerful three-dimensional design of its surfaces. The precise lines and the expressive interplay of the contours create a sense of movement and speed even when the bike is stationary. What is especially striking in this respect are the side wing contours of the fuel tank which significantly emphasise this effect. All lines seem to generate a sense of movement towards the front wheel and underline the playful ease of handling of the BMW Concept Stunt G310. Simultaneously the bike’s surfaces create a compact and distinctive silhouette emphasizing the favorable centering of masses around the engine block.

The slim front view of the G310 also draws attention to its high level of agility. The expressively modeled surfaces of the fuel tank result in a broad shoulder section which is underscored further by the design of the front facia. Similar to its front, the raised, filigree tail promises playful cornering and handling. It shifts the visual center of gravity to the front even further and in combination with the engine spoiler emphasizes the front wheel even more.

The numerous modifications are typical for a stunt bike; in making them Chris Pfeiffer brought his many years of experience as a stunt professional to bear in cooperation with the BMW Motorrad Design Team. Their single aim is to provide the best possible handling properties for the stunt rider’s feats on the asphalt. The lockable throttle ensures constant propulsion even when the rider’s hand has to let go of the throttle grip. In addition a slightly altered gear ratio secures greater propulsive force to the rear wheels at low engine speeds while the intentionally oversized rear wheel brake ensures reliable deceleration in every situation. A second, even larger rear wheel brake allows the rider to brake the rear wheel using only his middle finger, in case his right foot is not on the footrest in certain stunts. The additional brake lever is specially placed on the left side of the handlebars and can even be operated at the same time as the clutch. So-called axle pegs on the front axle and in the seat area give the rider additional options for placing his feet which go way beyond the possibilities offered by normal foot rests. The distinctive red crash bars provide additional protection for the engine. A special highlight on the G310 is the “stunt tail” which was specifically developed by BMW Motorrad and which has not been seen in this shape on a stunt bike. It is milled from solid aluminium and features an opening in the center, which offers the stunt rider a hold for his foot. Together with the non-slip seat, the aluminium component also ensures a stable seating position when riding thanks to its shape.

Modern color and material design.

The color concept features the classic BMW motorsport color white as the base color as well as red and blue in combination with the national colors of the Brazilian flag in a modern interpretation. The neon green and yellow color and material design is certain to attract attention. The bright neon colors extend along the entire body thereby emphasizing the dynamic lines and surfaces of the bike. The core of the bike, the drivetrain, features darker colors and moves the visual center of gravity even lower. Edgar Heinrich, Head of BMW Motorrad Design sums up: “The BMW Concept Stunt G310 is a real eye-catcher. Everything on this concept seems to be shouting out to ride it and defy the laws of gravity.”
