The BMW G 310 R stands as a testament to efficient German engineering, featuring a unique 180-degree reversed cylinder head design. By tilting the cylinder toward the rear and rotating the head, BMW engineers achieved a straight intake path and a lower center of gravity, significantly enhancing the flickability of this urban roadster.
Technical Engineering Overview
The Euro 5+ iteration (Type 0G41/25) introduces refined electronic throttle control (Ride-by-Wire) and an automatic idle speed increase to prevent stalling during low-speed maneuvers. This model is specifically engineered to meet stringent emission standards without sacrificing the punchy torque delivery of its 313cc liquid-cooled single-cylinder engine.
Maintenance Essentials
To maintain the longevity of the G 310 R, adhering to the specific lubricant and electrical requirements is paramount. The engine utilizes a 1.6-liter sump requiring SAE 15W-50 oil meeting JASO MA2 standards to ensure optimal clutch performance and gear lubrication.
- Ignition: The high-performance NGK LMAR9E-J spark plug is critical for ensuring complete combustion and meeting Euro 5+ emission targets.
- Chassis: Tire pressures are lower than typical heavy cruisers (1.7/1.9 bar), optimized for the lightweight 158.5kg (kerb) frame to provide maximum mechanical grip.
- Electrical: The YTX9-BS battery supports the increased electronic load of the LED lighting system and the Ride-by-Wire actuators.
MotoSpecsLab Verdict
The BMW G 310 R remains the benchmark for entry-level premium roadsters. Its engineering focus on mass centralization and refined fueling makes it an ideal candidate for both novice riders and urban commuters seeking BMW’s signature build quality in a compact package.
