2018 BMW G 310R Overview
For 2018, BMW offers the G 310R as a naked bike motorcycle with 313 cc on tap. The 2018 BMW G 310R is built around a Liquid-cooled single cylinder, four-stroke, backward-canted, 4 valves engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 10.6:1. Out on the road, the G 310R delivers 25 kW @ 9500 rpm of peak power and 28 Nm @ 7500 rpm of torque. Flat out, it's quoted at 145 km/h. In everyday use, the 2018 G 310R tips the scales at 158.5 kg, carries an 11 L fuel tank, offers a seat height of 785 mm and spans a 1374 mm wheelbase. That's roughly 42.5 kg lighter than the average naked bike in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2018 BMW G 310R spec sheet below.
2018 BMW G 310R compared with other bikes in the Naked bike category
Measured against other bikes in the Naked bike category in our database (up to 1125 models, one entry per model), the 2018 BMW G 310R comes out as follows.
- With 158.5 kg, the G 310R has the 141st lightest wet weight of 942 bikes in the Naked bike category, 21% below the category average of 201 kg.
- Power-to-weight ratio of 158 W/kg is lower than that of 491 of the other 580 bikes in the Naked bike category.
- Only 174 of the other 1124 bikes in the Naked bike category have a lower power output than the 25 kW of the G 310R.
- Narrowing the field to the 409 models within five model years of it, the wet weight of 158.5 kg is lighter than that of 336 of the other 408.
Versus the 2017 model
The figures we track are unchanged from the 2017 model: peak power, peak torque, wet weight, displacement, seat height and top speed all match.
2018 G 310R - Pros & Cons
Strengths
-
⚡
Strong power output: Peak output on the G 310R is 25 kW @ 9500 rpm and 28 Nm @ 7500 rpm of torque - strong numbers for what it is.
-
🛑
Strong front braking: The disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.
-
🛡️
ABS fitted: With ABS on board, hard braking on a damp or gravelly surface is far less likely to end in a locked wheel.
Considerations
-
⛽
Modest fuel capacity: An 11 L tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
-
⚙️
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.
Wear Points & Servicing Notes
Cooling system servicing
With Liquid Cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.
Valve clearance checks
Valve clearances on Double Overhead Cams/Twin Cam (DOHC)-equipped engines like the G 310R's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.
Brake disc and pad wear
Single 300mm disc, ABS up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by 41mm Telescopic fork up front and Aluminium swinging arm in conjunction with a directly mounted spring strut at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Chain final drive on the G 310R means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The Tubular steel frame in grid structure with bolt-on rear frame chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
G 310R - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2018 BMW G 310R with its 313 cc naked bike should cover the same ground every time: service history, drivetrain condition, and any oil seepage 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 8 years old, this naked bike is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept G 310R settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for the G 310R's 313 cc liquid-cooled single cylinder, four-stroke, backward-canted, 4 valves - keep to the manufacturer's interval rather than stretching it. With a 10.6:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.
Carburetor upkeep
A G 310R that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
Valve clearance service
There's no reliable seat-of-the-pants way to tell if a G 310R's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
