Venturing onto new ground is the G 310 R, featuring a newly developed 313 cc liquid-cooled single-cylinder engine with four valves and two overhead camshafts, together with electronic fuel injection. The capacity of 313cc results from a bore of 80 millimetres and a stroke of 62.1 millimeters, BMW said.
Designed for the world market, the bikes will be produced in India by partner TVS Motor Co. They can run on the most diverse fuel qualities, and meet all emission standards and local requirements.
The engine has a backward-tilted cylinder in open-deck design with the cylinder head turned by 180 degrees, making it possible to position the intake tract at the front, viewed in the direction of travel. 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 R is a very dynamic partner in conjunction with the low unladen weight of 158.5 kilograms, according to the OEM.
The compact proportions and the short wheelbase promise fast changes of direction, while the high rear hints at the bike's sporty genes. The small headlamp mask, dynamically modeled fuel tank trim elements and roadster proportions make for an eye-catching ride. In spite of its naked bike character, the side surfaces in body color create a closed silhouette.
The bike has a rigid tubular steel frame, upside-down fork and long swinging arm for added ride stability, precise steering response and sound handling. In terms of suspension, the new G 310 R has a torsionally stiff, robust tubular steel frame in grid structure with bolt-on rear frame. 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 mounted directly.
As for the ride, the new G 310 R features a markedly relaxed seating position, BMW noted. All switches and controls are simple and secure to handle, it added.
The G 310 R is fitted with ABS as standard. It combines a powerful brake system with 2-channel ABS. At the front wheel, a single-disc brake with radially bolted four-piston fixed caliper and a brake disc diameter of 300mm ensures powerful and stable deceleration, the company said. At the rear, this function is performed by a 2-piston floating caliper in conjunction with a 240mm brake disc.
The G 310 R instrument cluster has a large liquid crystal display that offers excellent clarity and a wide range of information, the OEM noted.
