2021 BMW G 310GS Overview

The 2021 BMW G 310GS is a sport motorcycle built around 313 cc of displacement. Under the tank sits a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 10.9:1. 2021 BMW G 310GS delivers 25 kW @ at 9500 of peak power and 28 Nm @ 7500 rpm of torque. The factory-quoted top speed stands at 143 km/h, making it a capable performer in its class. From a practical standpoint, the 2021 G 310GS tips the scales at 175 kg, carries a 11-litre fuel tank, offers a seat height of 835 mm and spans a 1420 mm wheelbase. That's roughly 27.7 kg lighter than the average sport motorcycle in our database.

2021 G 310GS - Pros & Cons

Strengths

  • Strong power output: 2021 BMW G 310GS makes 25 kW @ at 9500 with 28 Nm @ 7500 rpm of torque - competitive figures for its class.
  • Fuel injection: The fuel injectionwith front-intake 42mm throttle body system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.

Considerations

  • Tall seat height: The 835 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
  • Modest fuel capacity: The 11-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
  • Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Cooling system servicing

The Liquid cooled system on the G 310GS needs a coolant change roughly every two years (or per the service schedule) - skipping it lets the coolant turn acidic and corrode the aluminium water passages over time.

Fuelling & injector care

Fuelling comes from fuel injectionwith front-intake 42mm throttle body. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Valve clearance checks

Double Overhead Cams/Twin Cam (DOHC) valve actuation on the G 310GS means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.

Brake disc and pad wear

The Single 300mm disc, 4-piston fixed caliper, radially bolted front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the G 310GS runs 41mm Upside-down fork, non-adjustable and Linkage-free spring-preload adjustable shock at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Tubular steel frame with bolted rear frame - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

G 310GS - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2021 BMW G 310GS, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained G 310GS should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any G 310GS. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Carburetor upkeep

Keep the carburetors clean and free of deposits. If the G 310GS has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used G 310GS. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
