The 2015 BMW G 650GS Sertao is built around a Single cylinder, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 11.5:1. Internally, bore and stroke are 100 x 83 mm. Out on the road, the G 650GS Sertao delivers 37 kW @ 6500 rpm of peak power and 60 Nm @ 5000 rpm of torque. Flat out, it's quoted at 169 km/h. In everyday use, the 2015 G 650GS Sertao tips the scales at 191 kg, carries a 14-litre fuel tank, offers a seat height of 860 mm to 900 mm and spans a 1484 mm wheelbase. That's roughly 21.4 kg heavier than the average enduro / off-road motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2015 BMW G 650GS Sertao spec sheet below.

2015 G 650GS Sertao - Pros & Cons
Strengths
-
⚡
Strong power output: Peak output on the G 650GS Sertao is 37 kW @ 6500 rpm and 60 Nm @ 5000 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.
Considerations
-
📏
Tall seat height: An 860 mm to 900 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
-
⚙️
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 650GS Sertao'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, 2 piston caliper 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 with stabilizer bridge up front and Spring setting and rebound stage damping continuously adjustable, 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 650GS Sertao means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The Bridge-type steel section frame with bolted-on rear section 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 650GS Sertao - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2015 BMW G 650GS Sertao with its 652 cc enduro / off-road 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 11 years old, this enduro / off-road 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 650GS Sertao settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for the G 650GS Sertao's 652 cc single cylinder, four-stroke - keep to the manufacturer's interval rather than stretching it. With an 11.5:1 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 650GS Sertao 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 650GS Sertao'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.
