Engine Displacement: 313 cc
The G 310 R utilizes a 313 cc liquid-cooled single-cylinder engine. Its hallmark is the reverse-inclined cylinder head, which rotates the cylinder 180 degrees. This allows for a straight path for the air-fuel mixture, improving intake efficiency and centralizing mass for better flickability in corners.
Max Power: 34 PS @ 9,250 rpm
The engine produces 34 PS (25 kW) of peak power. Thanks to the latest electronic throttle (Ride-by-Wire), the power delivery is exceptionally smooth, eliminating the "jerky" low-speed behavior often found in small-displacement singles.
Max Torque: 28 Nm @ 7,500 rpm
With 28 Nm of torque, the G 310 R is punchy in the mid-range. This torque profile is ideal for the "stop-and-go" nature of urban commuting in cities like Kathmandu, allowing for quick bursts of speed without constant downshifting.
No. of Cylinders: 1
This single-cylinder unit is engineered with a balance shaft to cancel out secondary vibrations. This results in a refined engine feel that remains comfortable even as you approach the 10,500 rpm redline.
Valve Train: DOHC
The Double Overhead Camshaft (DOHC) setup uses finger followers with DLC (Diamond-Like Carbon) coating. This high-tech coating minimizes friction and wear, a technology directly inherited from the BMW S 1000 RR superbike.
Fuel System: Electronic Fuel Injection (FI)
The BMS-E2 fuel injection system provides precise metering. It includes an automatic idle speed increase feature, which prevents the engine from stalling when taking off—a common hurdle for newer riders.
Top Speed: 143 km/h
The G 310 R reaches a claimed top speed of 143 km/h. Its roadster ergonomics place the rider in a slightly forward-leaning "attack" position, reducing wind resistance compared to the upright stance of its GS sibling.
Mileage: 30.3 kmpl
The bike delivers an ARAI-certified mileage of 30.3 kmpl. In real-world urban conditions, riders typically see between 28-32 kmpl, making it a premium yet relatively economical daily commuter.
