BMW's Best Seller of 2020: The R 1250 GS
Updated: Sep 2
BMW Motorrad delivered 169,272 motorcycles worldwide in 2020, and the R 1250 GS was the bike doing most of the work behind that total. What BMW did not do was say how many. For 2020 the company reported boxer volume as a family and left the GS itself uncounted, which makes this the only year in our 2020 to 2025 run where the answer comes with no number attached.
That absence is worth stating up front, because BMW is the only manufacturer in this series that publishes model-level sales at all. Harley-Davidson publishes none. Polaris publishes none for Indian, and Honda publishes none for the US market, so those three picks rest on family-level shipment data and each company's own marketing language rather than on counted units. BMW normally does better than that. For 2020 it published almost 80,000 boxer-engined motorcycles across the whole boxer range, with no R 1250 GS line inside it, so we are not going to invent one. Every BMW figure in this series is global, and there is no US model-level data for any year in this window.
What the R 1250 GS was in 2020
The 2020 R 1250 GS ran BMW's 1254cc ShiftCam boxer twin, rated at 136 hp at 7,750 rpm and 143 Nm, which is 105 lb-ft, at 6,250 rpm. That torque figure carries a footnote worth keeping. BMW's global material quotes 6,250 rpm, while BMW USA published 6,500 rpm for the same engine. The engine did not change between those two documents. We use 6,250 rpm and flag the discrepancy rather than quietly pick the one we prefer.
Seat height decides this motorcycle for a lot of riders, so it gets stated properly rather than rounded off. The standard seat puts the rider at 33.5 inches. The optional taller seat raises that to 34.3 inches. Claimed weight was 549 lb. US pricing opened at $17,895 for the R 1250 GS, with the R 1250 GS Adventure at $20,195. Nothing about those numbers is beginner-friendly, and the GS has never pretended otherwise.
The GS formula had held for four decades by then, and 2020 was the anniversary of exactly that: a boxer twin, a tall riding position, and a motorcycle sold on the promise of distance rather than on lap times. Very few of these bikes ever see the terrain their marketing implies, and that has never dented the appeal. The GS sells because it works as a fast, comfortable long-haul road bike first, with the capability underneath available if the pavement ends.
What was actually happening at BMW in 2020
2020 was the GS platform's 40th anniversary, and BMW spent the year celebrating one long-running success while launching something with no precedent in its catalogue. The R 18 cruiser arrived with the 1802cc Big Boxer, the largest boxer engine BMW has ever built, aimed at a segment the company had never seriously contested.
Now the careful part. BMW has never published R 18 unit figures, and the cruiser has not appeared in a single model-level sales highlight anywhere across 2020 to 2025. That pattern is consistent with a soft reception. It is not proof of one, and absence from a press release is not a sales number. We flag it as unverified because that is what it is, and because plenty of coverage elsewhere has quietly upgraded the same silence into a fact.
Company-wide, BMW finished 2020 at 169,272 motorcycles, with the boxer family accounting for almost 80,000 of them. For how that sat against Harley-Davidson, Indian and Honda in the same year, our best selling motorcycles of 2020 roundup puts the whole field on one page.
How to read a year with no number
If you are shopping a used 2020 R 1250 GS, the missing figure changes nothing about the motorcycle. The 1250 was mid-cycle, well sorted, and unchanged in the ways that matter from the bikes either side of it. What the missing figure should change is how much weight you give any article that tells you exactly how many GS units BMW moved in 2020. Nobody outside BMW knows. The company chose to report the boxer family instead, and that choice is the story of the year.
There is a second reason to care. The almost 80,000 is a boxer-family number, and the boxer family is not just the GS. It includes the R 18 and every other horizontally opposed twin BMW sold that year. Treating that aggregate as a GS figure, which happens constantly in search results, inflates the GS by an unknown margin. The correct read is that the GS was the largest single slice of an almost 80,000 unit boxer family inside a 169,272 unit company, and that the slice itself was never published.
It also sets up the contrast that runs through the rest of this series. From 2021 BMW starts putting combined GS and GS Adventure numbers on the record, and by 2025 it splits individual models for the first time. Measured against three manufacturers that publish nothing at all, even a rounded combined figure is a lot. Our 2020 four-brand comparison covers how the GS stacked up on specification against the other category leaders that year.
2020 is the year where the BMW answer is solid and the BMW number is not. The R 1250 GS was the company's best seller, the boxer family carried almost 80,000 units, and the specific GS total does not exist in public. That is the honest version, and it is the version we are going to keep printing.
