2020 BMW R 1250GS Adventure Overview

BMW R 1250GS Adventure is an enduro / off-road motorcycle, displacing 1254 cc. Power comes from a Two cylinder boxer, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 12.5:1. On the performance side, it delivers 136 hp @ 7750 rpm of peak power and 143 Nm @ 6250 rpm of torque. Top speed is factory-quoted at 200 km/h. On the road, the 2020 R 1250GS Adventure tips the scales at 268 kg, carries a 30-litre fuel tank, offers a seat height of 890 mm to 910 mm and spans a 1504 mm wheelbase. That's roughly 69.2 kg heavier than the average enduro / off-road motorcycle in our database. The full 2020 BMW R 1250GS Adventure spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2020 R 1250GS Adventure - Pros & Cons

Strengths

  • Strong power output: With 136 hp @ 7750 rpm and 143 Nm @ 6250 rpm of torque on tap, the R 1250GS Adventure is no slouch for its class.
  • Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
  • Large fuel range: A 30-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
  • Low-maintenance final drive: Running Shaft final drive cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

  • Tall seat height: At 890 mm to 910 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.

Wear Points & Servicing Notes

Heat management in traffic

Because the R 1250GS Adventure relies on airflow rather than a coolant jacket, expect noticeably more radiant heat at low speed and in traffic. It's inherent to air cooling, and ventilated gear largely offsets it.

Fuelling & injector care

The Electronic intake pipe injection on the R 1250GS Adventure needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

Valve clearance checks

With Double Overhead Cams/Twin Cam (DOHC) valve gear, the R 1250GS Adventure 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 2x 305mm floating discs, 4-piston radial brake calipers - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The R 1250GS Adventure's suspension runs BMW Motorrad 37mm Telelever, central spring strut at the front. The rear uses Cast aluminium single-sided swing arm with BMW Motorrad Paralever, WAD spring strut, continuously adjustable spring preload by means of hand wheel, rebound-stage damping adjustable by hand wheel. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The R 1250GS Adventure uses shaft final drive: essentially maintenance-free day to day, with periodic gear-oil changes the only real service item.

Frame & chassis check

Built around a Two-section frame concept consisting of main frame with bolt-on rear frame, load-bearing engine, the R 1250GS Adventure's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

Handling the weight at a standstill

268 kg puts the R 1250GS Adventure toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.

R 1250GS Adventure - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2020 BMW R 1250GS Adventure, 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 R 1250GS Adventure should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a R 1250GS Adventure'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.

Fuel system care

Fuel injection on the R 1250GS Adventure needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.

Valve clearance service

Valve clearances are easy to overlook on a used R 1250GS Adventure 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.
