BMW almost certainly revealing basis of new mainstream entry model with ‘concept’ G 310
With the world premiere of the BMW Concept Stunt G 310 at South America’s largest motorcycle show, BMW Motorrad are almost certainly showing off a future new single-cylinder production model.
BMW do not waste money on such studies unless a production bike design has been signed off on looking towards mainstream production of a future model.
Thus what we are most likely looking at here, is the first incarnation of an all-new single-cylinder motorcycle aimed at new riders and bringing them into the BMW brand right from their first motorcycle purchase.
The BMW Concept Stunt G 310 features a newly developed single-cylinder engine with a reverse inclined bore and rear facing exhaust ports.
This reversed cylinder head design helps to allow for a short wheelbase while retaining the advantages of a long swingarm.
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.
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 BMW Concept Stunt G 310 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 centre, 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.
The colour concept features the classic BMW motorsport colour white as the base colour as well as red and blue in combination with the national colours of the Brazilian flag in a modern interpretation. The spectacular neon green and yellow colour and material design is certain to attract attention. The bright neon colours extend along the entire body thereby emphasising the dynamic lines and surfaces of the bike. The core of the bike, the drivetrain, features darker colours and moves the visual centre of gravity even lower. Edgar Heinrich, Head of BMW Motorrad Design sums up: “The BMW Concept Stunt G 310 is a real eye-catcher. Everything on this concept seems to be shouting out to ride it and defy the laws of gravity.”
