The new BMW G 310 GS –Â Honey, I shrunk the GS!
BMW’s entry into the lower capacity market, the G 310 R, will be on Australian shores soon, but even before that new single-cylinder model hits the market it has already spawned a GS spin-off with BMW announcing the G 310 GS this week in Milan.
The BMW G 310 GS can be identified as a genuine GS at first sight. With its characteristic, high front fender, striking flyline and short, high rear, the BMW G 310 GS features classic elements of its big GS sibling models. Its compact proportions with a short wheelbase, a 19-inch front wheel and extended spring travel make for a typical upright posture, promising an agile, nimble riding response.
The centrepiece of the new BMW G 310 GS is the 313 cc liquid-cooled single-cylinder engine known from the G 310 R with four valves and two overhead camshafts together with electronic fuel injection. The capacity of 313cc results from a bore of 80mm and a stroke of 62.1mm.
A salient feature of the single-cylinder engine in the G 310 GS is the fact that its cylinder is tilted to the rear and its cylinder head is rotated by 180 degrees: intake at the front, outlet at the rear. This configuration follows the logic of a straight, power-enhancing supply of fresh air-fuel mixture and also has positive consequences in terms of the bike’s architecture. With an output of 25 kW (34 hp) at 9 500 rpm and a maximum torque of 28 Nm at 7 500 rpm, the engine of the new G 310 GS is the ideal partner for dynamic riding pleasure, in conjunction with the low unladen weight of 169.5 kilograms according to DIN.
The new G 310 GS provides a relaxed seating position that enables carefree motorcycling pleasure both on the road and during excursions along forest paths and gravel tracks. As is characteristic of BMW Motorrad, all switches and controls are simple and secure to handle. Great importance was attached to simple and safe operation, taking into account the most diverse rider anatomies.
Bridge-type tubular spaceframe, upside-down fork and long swinging arm for a high degree of ride stability, a precise steering response and light handling.
In terms of its suspension, the new G 310 GS is similar to the G 310 R roadster in using a tubular steel spaceframe with bolt-on rear section that combines torsional rigidity with robust quality. Given its good stiffness balance, this provides the basis for excellent ride stability and a precise steering response. The front wheel suspension is taken care of by a solid upside-down fork while at the rear there is an aluminium swinging arm in conjunction with a spring strut that is mounted on it directly.
Like all BMW motorcycles, the new G 310 GS comes with ABS as standard. It combines a high-performance brake system with 2-channel ABS for efficient deceleration and short braking distances. For use over light terrain the ABS in the new G 310 GS can be conveniently deactivated at the press of a button if required. The G 310 GS instrument cluster has a large liquid crystal display that offers excellent clarity and a wide range of information.
