When I first laid eyes on our 2021 BMW R 1250 GS 40 Years of GS Edition test bike, I thought of my Uncle Clive. He had worked for the doomed British Leyland for years before accepting a role with BMW. His garage, once the perpetual home to a gleaming Rover, was now occupied by a stunning 5 Series sedan, but it was the new motorcycle, waiting in the shadows, which drew my attention. It was unlike any I had seen before.
The air-cooled cylinder heads of its opposed Twin jutted out brazenly from the sides of the engine cases, protected by crash bars. Though it wasn’t a dirtbike, it shared some of the same characteristics, like a long, single-piece seat and a high, fixed front mudguard. Most distinguishing of all, the rear wheel seemed to float in space. Uncle Clive, always ready to explain an engineering feature, eagerly directed me to view it from the other side and began a lengthy monologue on the benefits of a combined single-sided swingarm and driveshaft. The details were lost on me. I was only 12 at the time.
It was 1984. What I didn’t know back then was how bold the path was that BMW had blazed a few years earlier with the R 80 G/S, the first motorcycle that delivered on-road comfort and performance and genuine off-road capability in equal measure. Between 1981 and 1985, the rugged G/S proved its mettle with four wins in the grueling Paris-Dakar Rally and three wins in the Baja 1000. And that single-sided swingarm – then called the Monolever – was lighter, stronger, and less expensive to manufacture than a two-sided swingarm with shaft drive, and it simplified repairs and maintenance.
What I also didn’t know back then was that those two letters – G for Gelande (“terrain” in German) and S for StraBe (“street”), the slash between them soon dropped – would evolve into an abbreviation for adventure long before ADV stickers found their way onto aluminum panniers. Or that, years later, I would watch Ewan McGregor and Charlie Boorman ride R 1150 GS Adventures – descendants of that original R 80 G/S – around the world and be inspired to embark on my own adventures.
I rode an R 1100 GS with the Dakar-style tank through the soggy mountains of Wales. My wife and I did two-up tours on R 1200 GSs through the canyons of Arizona and Utah, across Canada, and through the wilds of Chile and Argentina. I rode the first liquid-cooled 1200 down California’s fog-shrouded Highway 1 and around the Rockies of Colorado. I’ve ridden them in snow, rain, rubble, and the dreaded sand. Once, I somersaulted a GS down a hill at BMW’s off-road Rider Academy in South Carolina, picked it up, and rode it back to base.
The earlier models required close attention to the oil level, and although I’ve suffered the odd puncture, a torn tire, and a luggage rack that disintegrated after 11 hours on Chilean roads, I’ve never had one fail on me. Not once.
There’s an obvious through-line from Uncle Clive’s R 80 G/S to the 2021 R 1250 GS tested here, but BMW’s flagship adventure bike has come a long way over the past four decades. Over multiple generations, engine displacement grew from 798cc to 1,254cc and output increased from 50 horsepower to 136, measured at the crank. (On Jett Tuning’s dyno, our test bike grunted out 119 horsepower at 7,900 rpm and 91 lb-ft of torque at 6,500 rpm at the rear wheel.) Air cooling evolved into air/oil cooling and then air/liquid cooling. Cylinders had two valves, then four, and overhead valves evolved into dual overhead cams with variable valve timing. It had five speeds, then six, and a single-plate dry clutch evolved into a multi-plate wet clutch.
As the engine and drivetrain evolved, so did the chassis. The Monolever was replaced by the Paralever, solving the problem of shaft jacking. The telescopic fork was replaced by the Telelever, which moved suspension action from the fork tubes to a single shock attached to the front of the frame and an A-arm, reducing front-end dive under braking. A single-disc front brake and rear drum were replaced by dual discs up front and a single disc out back.
We recently tested the new Kawasaki KLR650, a dual-sport that was introduced in 1984 (as a 600), just a few years after the R 80 G/S. Resistance to change and dedication to simplicity (and affordability) have been points of pride for the KLR, so much so that adding electronic fuel injection and optional ABS on the 2022 model was a Big Deal.
BMW, on the other hand, has taken an early-adopter approach to technology. Fuel injection and ABS were offered on the GS in the early ’90s. Traction control (known as ASC) and Enduro ESA (Electronic Suspension Adjustment) were offered in 2008. Five years later, the GS got throttle-by-wire, riding modes, a Multi-Controller wheel for navigating settings and menus, multiple ABS modes, and Dynamic ESA that adapted the suspension to riding conditions. In 2019, the GS got the ShiftCam variable-valve timing system, a 5.7-inch TFT color display, and infotainment via Bluetooth connectivity to a smartphone. And the latest GS has a 6-axis IMU, which provides input for cornering ABS, lean-angle-sensitive traction control, and semi-active suspension, all of which have different settings for each riding mode. A new option on the 2024 model will supposedly do your taxes, but don’t quote me on that.
The GS’s enduring and broad appeal stems from its excellent handling, versatile performance, comfortable ride, comprehensive features, and renowned durability and reliability. It’s a capable canyon carver as well as a comfortable highway cruiser, great for loading up with a passenger and gear, and is surprisingly capable off-road. Nearly every GS owner – and motojournalist – has, at one time or another, described the bike as the Swiss Army knife of motorcycles.
Riding through Chile and Argentina with my wife on an R 1200 GS is one of the highlights of my motorcycling experience. Patagonia’s vast mountain ranges are a delight, but finding fuel was sometimes a challenge, and on one desolate backroad, I gladly accepted a sheep farmer’s offer of some fuel he kept in an old watering can. It’s at times like these you will be grateful for the knock sensors, which allow the GS to run on low-octane gas.
Riding the R 1250 GS, I recalled that first trip through the Welsh mountains on the ’90s-era 1100. The performance improvements are night and day, with a huge increase in power but only a few pounds of additional weight. While the difference in acceleration is notable, the most pleasing aspect of the 1250’s engine is the abundant torque across the rev range. It allows for lazy short-shifting when relaxed riding is called for, or rewarding grunt when you feel like pushing the envelope.
The most telling improvement is the difference in handling and suspension. While older GS models responded begrudgingly to spirited inputs, our 1250 test bike, which was equipped with the optional Premium Package ($3,925) that includes Dynamic ESA, Ride Modes Pro, and a whole lot more, rolls out the red carpet. The latest version of BMW’s semi-active suspension setup now takes input from the IMU and automatically adjusts for various loads. The Telelever front end has always dulled meaningful feedback, but you can push the GS close to its limits with relaxed confidence. Chassis pitch is minimal and suspension compliance is phenomenal. It’s like riding on air.
BMW made a few updates for 2021, starting with standard Integral ABS Pro. As before, the system is linked front to rear, so the hand lever actuates both front and rear brakes, but the brake pedal only actuates the rear brake. The ABS software has been updated to improve braking stability, and it works in conjunction with the IMU for better control on inclines. ABS Pro adapts to different on-and off-road conditions based on riding mode, with special settings in Enduro Pro and Dynamic Pro modes, and a more compact ABS unit is one pound lighter. Overall braking performance was excellent, whether riding solo or with the GS fully loaded and my wife riding pillion.
A new Eco riding mode takes advantage of the ShiftCam system to maximize range from the 5.3-gallon tank. All-around LED lights are standard, and a new adaptive headlight is available as an option, adjusting the sideward angle of the beam up to 35 degrees relative to lean angle to light up curves. Hill Start Control also comes as standard and was a useful addition in the traffic of hilly San Francisco. Just apply sharp pressure to either the brake lever or pedal at a stop, and the rear brake stays locked until you pull away. With optional HSC Pro (part of the Premium Package), the function can be customized to automatically activate when coming to a standstill on a gradient, and there are special settings for use in Enduro and Enduro Pro off-road modes.
Our test bike featured the 40 Years of GS Edition Package ($1,750), which is inspired by the “bumblebee” black-and-yellow paint scheme of the R 100 GS. In addition to yellow accents and special graphics, it has a gold handlebar with yellow handguards, yellow cylinder head covers, gold anodized cross-spoke wheels, and a stainless-steel luggage rack. Our test bike was further equipped with BMW’s side case carriers and Atacama soft side cases and luggage roll ($2,352).
There certainly is a lot of newness to this latest GS, with all its sensors and settings, with its customizability and high-tech sophistication. But for someone like me, who has put more miles on more GSs in more places than I have on any other motorcycle, there’s a lot of familiarity too. Like the distinctive sound of the boxer Twin when it fires up. Or the feel of the engine when hard on the gas. Or the sensation of leaning into a turn, aided by those horizontal cylinders keeping the weight down low.
Experience can’t help but color our opinions, as unbiased as we may try to be. So, if I’m honest, I’m more than a little partial to the big GS. Uncle Clive certainly started the fire all those years ago, but the embers were stoked over the course of thousands of miles in all sorts of conditions on three different continents. The GS has proven itself to me time and again, and this latest model is the most impressive yet.

I thought this was a review. It reads like a history lesson.
The R1250GS and the GSA are a great all rounder bike ,we have them in our fleet of rental bikes in Ireland. 100% agree with you the fact they never let you down. Great bike
I bought an 06 gsa with 34000 miles the summer of 2020. Enjoy the machine a lot. Last fall at 48000 miles the front ujoint broke, locking the rear wheel. I had noticed a vibration the prior day in the left footpeg, but failed to figure out the problem in time. These bikes aren’t indestructible, and cost a lot to fix. Not knocking them, but pay attention to them.
All of the latest/greatest technology to include 6,000 valve lash inspection.Harley really missed the boat going with hydraulic lifters.The dealerships could have made $$$ on that service item.
I had an ’18 1200GS, great bike but the dealer service prices were sky high. Being charged those prices made me feel like a real sucker. And after I changed my own oil after conferring with many BMW 1200 owners, using expensive, highly rated synthetic oil of the recommended viscosity, I was warned by the dealer’s service writer that I have set myself up to lose my warranty! He said if something breaks – BMW will try to pin it on the oil I used. Ouch.
Great review and glad you explained the history, it was a real benefit to someone new to the GS, although I have started late in life buying my first Gs1250 in December 2021. I have been riding all my adult life, starting on. Kawasaki kc100 at 17 years young in 1980 i passed my test then onto a K250c single with drum brakes front and rear. Then a honda twin 250n superdream ( often referred to as a “wet dream” but what a brilliant little bike, then an XT yamaha 250, then a break, and then triumph trophy, followed by a brilliant honda blackbird, then a Suzuki hyabusa, then a 2005 BMW K1200gt great bike, then brand new 2017 Yamaha MT10 can’t fault it, then brand new KTM1290 Super Adventure which I thought was amazing and don’t get me wrong, its a fantastic bike, but not a patch on the handling of the new BMW R1250 GSR Adventure, its all grown up with superb handling, comfort, performance, with everything that you could wish for as far as finish and gadgets, not cheap but i guess the best never is. Trouble is what could I possibly buy in the future to better the GS? !
Ya gotta admire the audacity of a company when an optional “package” costs more than a decent off-tarmac bike. Which raises a question. If a person has sufficient funds hidden under the mattress to buy a fully farkled GS, wouldn’t buying two less expensive but very different bikes satisfy both hubris and real world G/S functionality?
If I had the money, that’s the approach I would take. Then, of course, the compromises aren’t from trying to make one bike that does it all.
Actually, you could buy three top condition used bikes for the price of this guy and have three times the reason to ride and have fun.
Good point I thought about that myself
At one time I had a wonderful Kawasaki KLX250S dual-sport and a Triumph Sprint ST 955 triple. The Sprint was a ‘sport/tourer’ with emphasis on ‘haul-ass’, while the KLX was great to tool around on all of the US Forest Service roads nearby in SW Virginia. But the Sprint could NOT go off road, and the KLX struggled to cruise 70MPH on flat roads. My ’18 1200GS could haul on the interstate highways, cruise control, rider modes, ESA suspension, full TFT display plus their Navigator color mapping GPS unit. And curvy paved roads were fantastic fun. Then at a moment’s notice, I could find a little traveled forest road 100 miles from home and ride through gravel, rocks, mud, cross creeks, experience maybe 35-50 miles of mountainous forest trails and hunter roads, then again hit the highways and interstate and head back home. A great way to pass 8-10 hours on a nice day. The only issue I had with the GS ‘one-bike-can-do-it-all’ concept was its high weight. Invariably, off road, sooner or later I would get abruptly caught in by a barricaded farm road going up (or down) a mountain or be faced with crossing a 60′ long mucky mud puddle of unknown depth in the middle of nowhere with only a half-hour of sunlight left – time to turn this beast around – aah, don’t drop it !!
Very capable machine….but just a teeny bit overpriced.
Definitely one of my favorite motorcycles. I own one and it’s the one that I prefer to drive everyday☻
The problem with owning two or three bikes of different styles is that you can only ride one style at a time. And you have to choose that style and stick with it for the entire trip.
You also have two or three bikes to maintain and insure.
I used to have a Kawasaki Z1000 for sport and a Kawasaki KLR650 for distance and off road.
Now I have a 2022 R1250GS Ralleye. I usually get one day a week to ride and I go out for 8 to 10 hours. I ride fast on twisty roads. I ride gravel roads, dirt roads and easy to moderate trails. I do this all on the same ride.
At the end of the long day I put it in “Road”mode and ride it like one of the most comfortable sport tourers that it is all the way back home.
A couple times a year I go on 4 to 10 day cross country trips and again I do all different types of riding. You cannot do this with multiple bikes.
The BMW GS is an expensive bike, but it is worth every penny.
I’ve had 4 BMW GS’s over the years. This year, I acquired a ’22 GSA triple black with low suspension. When I’m hauling down technical asphalt roads, it’s a little too easy to scrape my boots. I’m not an advanced off-roader but I’ve done about 150 miles on it without pavement so far and forded 5 or 6 streams in the process….on 90/10 tires without issue. I’m mostly happy with the low suspension because I’m confident I will not drop this bike now. I’ve dropped every RT I’ve owned at least once during my time with it.
The GS is a different beast and the 1250 shift-cam engine is just stellar. I agree with all the others who complain about the high cost of maintaining one. It’s ridiculous. This bike should have hydraulic valve actuators. I’d give up 10% of the performance for that. The cost of dealer service just infuriates me. I will likely buy the tools, probably give up my warranty and do it all myself. I can afford to have the dealer do everything, but I won’t know a thing about the bike then. I feel that it’s important to carry the right tools and have knowledge of what you’re riding when you go off on a long journey. At least then you have a chance in remote areas.
Sorry…Did I really write that? I’ve had 4 BMW RT’s in the past, not 4 GS’s. The post above will make more sense if you fix the first sentence.
