BMW's Best Seller of 2025: The R 1300 GS Adventure

For 2025 BMW Motorrad did something it had never done in this six-year run: it published individual model figures. The R 1300 GS Adventure sold 33,570 units. The base R 1300 GS sold 32,555. After more than a decade of the standard GS leading, the Adventure variant took it, and for the first time we can say that with a number rather than a hunch.

This is the year the provenance section gets short, because for once there is little to qualify. No combined pairs, no three-model aggregate, no rounding. Two models, two counts, published separately. Everything else in this series still carries the usual warning: Harley-Davidson publishes no model-level units, Polaris publishes none for Indian, and Honda publishes none for the US, so the Street Glide, the Scout and the Rebel 500 remain consensus picks supported by segment data rather than measured winners. And the one BMW caveat that never goes away applies here too. These are global figures. BMW published a US total of 14,869 motorcycles for 2025 and no US model-level breakdown, so nothing here tells you which GS led in America.

The R 1300 GS Adventure

The Adventure runs the same 1300cc boxer as the base bike, 145 hp at 7,750 rpm and 149 Nm, or 110 lb-ft, at 6,500 rpm. What separates it is size. Claimed weight is 593 lb against 523 lb for the base R 1300 GS, and US pricing is $22,745 plus $695 destination, against $19,495 for the base GS. That is a substantial premium for a heavier motorcycle, and it is the more expensive, heavier bike that sold more of the two.

Seat height deserves care here, because the Adventure has the widest spread of any bike in this series. The base configuration runs 34.3 to 35.0 inches. Across the full range of seat and suspension options the spread is 31.0 to 36.0 inches. That 31.0 inch figure is a genuinely low number for a motorcycle of this mass, and the 36.0 inch figure is a genuinely high one. Two riders can buy the same model and end up five inches apart, which is why quoting a single seat height for a GS Adventure is close to meaningless.

The flip, and the first decline

The Adventure overtaking the base GS is a real change in what BMW's customers are buying, not a rounding artefact. 33,570 against 32,555 is close, but it is a measured result rather than an estimate, and it reverses a pattern that had held for more than ten years. Buyers chose the bigger tank, the bigger bodywork and the higher price in greater numbers than they chose the standard bike.

It happened in a down year. BMW Motorrad's 2025 global total was 202,563, the first decline in this window after four consecutive records and a fall from the all-time high of 210,408 in 2024. So the flip is not the product of a rising tide lifting the Adventure. It happened while the company as a whole was shrinking.

Both facts read better together than apart. A manufacturer whose volume is falling and whose most expensive flagship variant is gaining share is describing a customer base that is getting older and better funded rather than larger. For how that compares with what happened to Harley-Davidson, Indian and Honda in the same year, our best selling motorcycles of 2025 roundup covers all four.

What individual figures change for a buyer

The practical value of BMW finally splitting models is that you can now check a claim instead of trusting one. For five years the only honest answer to whether the GS or the GS Adventure sold better was that nobody outside BMW knew. Now there is a published answer for one year, and it is the opposite of what most people would have assumed. That should make you more sceptical of confident model-level claims about the years where no split exists, and about every other brand in this comparison, where no split has ever existed.

If you are choosing between the two bikes, the 2025 numbers are information rather than advice. The Adventure outsold the base GS by a narrow margin, which tells you the market is close to evenly divided and tells you nothing about which one suits you. The weight gap and the price gap are the decisions. Our R 1300 GS owner reports cover how that weight behaves in practice, including at the low speeds where it is felt most.

On height, configure before you conclude. A base-configuration Adventure at 34.3 to 35.0 inches rules out a lot of riders. The same model specified down toward 31.0 inches does not. The bike you sit on at a dealership is one point on a five-inch range, and treating it as the model's seat height is the most common mistake made about this motorcycle. Our 2025 four-brand comparison sets those figures against the Street Glide, the Scout and the Rebel 500, where the seat-height gap remains the widest single difference across the four.

2025 closes the series the way it should have opened. Real individual numbers, 33,570 for the R 1300 GS Adventure and 32,555 for the R 1300 GS, inside a 202,563 unit year that ended BMW's record run. One manufacturer out of four willing to publish that, and it took until the last year of the window.
