2020 BMW G 310R Overview
BMW G 310R is a sport motorcycle, displacing 313 cc. Power comes from a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 10.6:1. On the performance side, it delivers 25 kW @ 9500 rpm of peak power and 28 Nm @ 7500 rpm of torque. Top speed is factory-quoted at 143 km/h. On the road, the 2020 G 310R tips the scales at 158.5 kg, carries an 11-litre fuel tank, offers a seat height of 785 mm and spans a 1374 mm wheelbase. That's roughly 36.3 kg lighter than the average sport motorcycle in our database. The full 2020 BMW G 310R spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2020 G 310R - Pros & Cons
Strengths
-
⚡
Strong power output: With 25 kW @ 9500 rpm and 28 Nm @ 7500 rpm of torque on tap, the G 310R is no slouch for its class.
-
🛑
Strong front braking: Stopping power up front is strong thanks to the disc setup, with plenty of room to upgrade further with braided lines.
Considerations
-
⛽
Modest fuel capacity: Range between stops is limited by the 11-litre tank - plan fuel stops accordingly on longer routes.
-
⚙️
Chain final drive upkeep: Budget time for routine chain maintenance - it's cheap to replace but needs consistent attention to avoid premature sprocket wear.
Wear Points & Servicing Notes
Cooling system servicing
G 310R's Liquid Cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.
Valve clearance checks
With Double Overhead Cams/Twin Cam (DOHC) valve gear, the G 310R needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.
Brake disc and pad wear
Braking up front comes from single 300mm disc - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The G 310R's suspension runs 41mm Telescopic fork at the front. The rear uses Aluminium swinging arm in conjunction with a directly mounted spring strut. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The G 310R uses chain final drive, which is cheap to replace but needs regular cleaning, lubrication and tension checks to get a full service life out of the sprockets.
Frame & chassis check
Built around a Tubular steel frame in grid structure with bolt-on rear frame, the G 310R's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
G 310R - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2020 BMW G 310R with its 313 cc sport, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 6 years old, this sport is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy G 310R should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects the G 310R's 313 cc single cylinder, four-stroke like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). With a 10.6:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Carburetor upkeep
Deposits in the carbs are the usual culprit behind poor running on a stored G 310R - strip and clean the float bowls before the first start. Pilot jets clog first and get overlooked most, so make a point of checking them.
Valve clearance service
Valve clearances are easy to overlook on a used G 310R since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
