2020 BMW R 1250GS Overview

The 2020 BMW R 1250GS is an enduro / off-road motorcycle built around 1254 cc of displacement. Under the tank sits a Two cylinder boxer, four-stroke engine running Double Overhead Cams/Twin Cam (DOHC) valve actuation, a compression ratio of 12.5:1. The bore and stroke measures 102.5 x 76 mm. 2020 BMW R 1250GS delivers 143 Nm @ 6500 Revolutions of torque. The factory-quoted top speed stands at 200 km/h, making it a capable performer in its class. From a practical standpoint, the 2020 R 1250GS tips the scales at 249 kg, carries a 20-litre fuel tank, offers a seat height of 850 mm and spans a 1525 mm wheelbase. That's roughly 50.2 kg heavier than the average enduro / off-road motorcycle in our database. Scroll down for the complete 2020 BMW R 1250GS spec sheet covering every technical detail from suspension travel to tyre sizes.

2020 R 1250GS - Pros & Cons

Strengths

Fuel injection: The fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
Large fuel range: The 20-litre tank is generously sized, translating to extended range between stops - ideal for touring or longer commutes.
Low-maintenance final drive: Shaft drive (cardan) (final drive) final drive means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.

Considerations

Tall seat height: The 850 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Valve clearance checks

Double Overhead Cams/Twin Cam (DOHC) valve actuation on the R 1250GS means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.

Brake disc and pad wear

The Double disc. ABS. Floating discs. Four-piston calipers. front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the R 1250GS runs BMW Motorrad Telelever and Cast aluminium single-sided swing arm with BMW Motorrad Paralever at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by shaft - no chain or belt maintenance at all, though the drive-shaft oil should be changed on the manufacturer's interval.

Frame & chassis check

The frame is Two-section frame, front- and bolted on rear frame, load-bearing engine - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Handling the weight at a standstill

At 249 kg, the R 1250GS is a substantial machine - low-speed manoeuvring in car parks takes more physical effort than on a lighter bike, though the weight disappears once rolling.

R 1250GS - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2020 BMW R 1250GS, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained R 1250GS should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task on any R 1250GS. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.

Fuel system care

The R 1250GS's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used R 1250GS. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
