2012 G 650GS Sertao - Pros & Cons
Strengths
-
⚡
Strong power output: With 37 kW @ 6500 rpm and 60 Nm @ 5000 rpm of torque on tap, the G 650GS Sertao is no slouch for its class.
Considerations
-
📏
Tall seat height: At 860 mm to 900 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
-
⚙️
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 650GS Sertao'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 DOHC valve gear, the G 650GS Sertao 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, 2 piston caliper - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The G 650GS Sertao's suspension runs 41mm telescopic fork with stabilizer bridge at the front. The rear uses Spring setting and rebound stage damping continuously adjustable,. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The G 650GS Sertao 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 Bridge-type steel section frame with bolted-on rear section, the G 650GS Sertao's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
G 650GS Sertao - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2012 BMW G 650GS Sertao, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy G 650GS Sertao should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a G 650GS Sertao's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). 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 650GS Sertao - 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 650GS Sertao 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.
