About bmw
BMW's motorcycle history began in 1921 when the company commenced manufacturing engines for other companies. Motorcycle manufacturing now operates under the BMW Motorrad brand. BMW (Bayerische Motoren Werke AG) introduced the first motorcycle under its name, the R32, in 1923.
BMW merged with Bayerische Flugzeugwerke in 1922, inheriting from them the Helios motorcycle and a small two-stroke motorized bicycle called the Flink. In 1923, BMW's first "across the frame" version of the boxer engine was designed by Friz. The R32 had a 486 cc (29.7 cubic inches) engine with 8.5 hp (6.3 kW) and a top speed of 95 to 100 km/h (59 to 62 mph). The engine and gearbox formed a bolt-up single unit. At a time when many motorcycle manufacturers used total-loss oiling systems, the new BMW engine featured a recirculating wet sump oiling system with a drip feed to roller bearings. This system was used by BMW until 1969, when they adopted the "high-pressure oil" system based on shell bearings and tight clearances, still in use today.
The R32 became the foundation for all future boxer-powered BMW motorcycles. BMW oriented the boxer engine with the cylinder heads projecting out on each side for cooling as did the earlier British ABC. Other motorcycle manufacturers, including Douglas and Harley-Davidson, aligned the cylinders with the frame, one cylinder facing towards the front wheel and the other towards the back wheel. The R32 also incorporated shaft drive. BMW has continued to use shaft drive on its motorcycles and did not produce a chain driven model until the introduction of the F650 in 1994.
In 1931, BMW introduced the single-cylinder shaft-driven R2, which, as a 200 cc motorcycle, could be operated in Germany without a motorcycle licence at that time. The R2 headed a series of single-cylinder BMW motorcycles, including the 400 cc R4 in 1932 and the 300 cc R3 in 1936.
The BMW R12 and R17, both introduced in 1935, were the first production motorcycles with hydraulically damped telescopic forks.
In 1937, Ernst Henne rode a supercharged 500 cc (31 cubic inches) overhead camshaft BMW 173.88 mph (279.83 km/h), setting a world record that stood for 14 years.
Construction was so good that during World War II Harley-Davidson copied the BMW engine and transmission—simply converting metric measurements to inches—and produced the shaft-drive 750 cc (46 cubic inches) 1942 Harley-Davidson XA.
The terms of Germany's surrender forbade BMW from manufacturing motorcycles. In 1946, when BMW received permission to restart motorcycle production from US authorities in Bavaria, BMW had to start from scratch.
In 1955, BMW began introducing a new range of motorcycles with Earles forks and enclosed drive shafts. These were the 26 hp (19 kW) 500 cc R50, the 30 hp (22 kW) 600 cc R60, and the 35 hp (26 kW) sporting 600 cc R69.
On June 8, 1959, John Penton rode a BMW R69 from New York to Los Angeles in 53 hours and 11 minutes, slashing over 24 hours from the previous record of 77 hours and 53 minutes set by Earl Robinson on a 45 cubic inch (740 cc) Harley-Davidson.
For the 1968 and 1969 model years only, BMW exported into the United States three "US" models. These were the R50US, the R60US, and the R69US. On these motorcycles, there were no sidecar lugs attached to the frame and the front forks were telescopic forks, which were later used worldwide on the slash-5 series of 1970 through 1973. Earles-fork models were sold simultaneously in the United States as buyers had their choice of front suspensions.
In 1970, BMW introduced an entirely revamped product line of 500 cc, 600 cc and 750 cc displacement models, the R50/5, R60/5 and R75/5 respectively and came with the "US" telescopic forks noted above. The engines were a complete redesign. The roller and ball-bearings in the bottom end had been replaced by shell-type journal bearings similar to those used in modern car engines. The camshaft, which had been at the top of the engine, was placed under the crankshaft, giving better ground clearance under the cylinders while retaining the low centre of gravity of the flat-twin layout. The new engine had an electric starter, although the traditional gearbox-mounted kick starter was retained. The styling of the first models included chrome-plated side panels and a restyled tank. The /5 series was given a longer rear swingarm, resulting in a longer wheelbase. This improved the handling and allowed a larger battery to be installed.
The /5 models were short-lived, however, being replaced by another new product line in 1974. In that year the 500 cc model was deleted from the lineup and an even bigger 900 cc model was introduced, along with improvements to the electrical system and frame geometry. These models were the R60/6, R75/6 and the R90/6. In 1973 a supersport model, the BMW R90S, was introduced. In 1975, the kick starter was finally eliminated.
In 1995, BMW ceased production of airhead 2-valve engines and moved its boxer-engined line completely over to the 4-valve oilhead system first introduced in 1993.

Be honest, now
May is Motorcycle Safety Awareness Month, which makes it as good a time as any for all of us to take stock of our own riding habits, both good and bad. Most motorcyclists are familiar with the acronym “ATGATT”, but for those who aren’t, it stands for “All The Gear, All The Time”. That means wearing the right safety equipment every time you ride, whether you’re commuting to work, or hopping over to the corner store for a carton of milk.

When it's a 451, d'uh. In our last Question of the Day, we asked about some of the more… questionable names given to motorcycles (Hondas seemed to come up fairly often in the replies, which is both interesting and somehow not surprising.) I mentioned how it’s generally safer for a manufacturer to stick to a combination of letters and numbers. While that’s generally true, apart from the occasionally comical practice of tackling on another “R” to make a model sound sportier ( looking at you again, Honda), it does bring the focus onto yet another common pet peeve: motorcycles with misleading numbers in the name.

Evaluating a sport-touring tire in extreme conditions
Photos by Metzeler
Designing a sport-touring tire must be one of the hardest challenges in motorcycling. In a way, you’re asking for it all. The sport-touring customer wants a tire that offers handling like a sportbike, but with the mileage of a touring bike.

Keeping the shiny bits shiny
There is sound logic behind popping a bottle of your favorite suds, saddling up next to your bike after a Sunday ride, and going over every shiny bit of chrome with a soft cloth to ensure its gleaming. Protecting your motorcycle’s chrome is about getting ahead of the game with preventative maintenance, ensuring that all the glistening chrome-plated components can continue to thrive for years. In this article, we’ll discuss the nitty-gritty related to chrome, from why it’s used to how owners can keep it in excellent shape.

The long-term KTM 390 ADV Project
Photos by Joe Jackson
If you’ve had a pulse the last five years or so, you’ve noticed the urge to take two wheels into the dirt has swept through the motorcycle community like a rogue wave. Riders across age ranges, experience levels and even financial demographics have turned to off-road, not instead of, but in addition to any and all riding they were previously doing. So it’s no surprise to see small-sized ADV bikes plodding along behind the surge like the sure-footed mules that they are.

After scrolling through endless lists of famous quotes looking for something which really suits my condition, I landed on this:
“There is only one thing that makes a dream impossible to achieve: the fear of failure.” —Paulo Coelho
It’s not the most profound of the options. Nor the most touching or even poignant. But how I interpret the meaning was the most encouraging.

Smaller, faster, more complex
An R 1300 GS has never existed until now. An obvious statement, but truly, this is a new motorcycle that, while carrying with it the spirit of what the BMW GS name embodies, is delivered in a completely new way. The 1300 GS is like no motorcycle that has come before it wearing the storied moniker.

Full LED lighting and lean-sensitive electronics now standard equipment
BMW announced minor updates to its R 1250 R, giving the Boxer-engined roadster a full LED headlight, and making some previously optional electronics standard, all while keeping the price unchanged at $14,995. Visually, the 2023 BMW R 1250 R looks similar to the previous model. The most noticeable change is the new LED headlight, which can be upgraded to an optional adaptive turning light.

Elegant contours, hard storage, and big jugs
Our perception of the world is influenced by both nature and nurture. Just as our individual experiences shape how we view situations, the same can be said for the handlebars you sit behind. Each bike delivers its own unique experience that plays a part in how you interact with and take in the scenery around you whether that be flying through mountain roads at warp speed, filtering through traffic on the way to work, or cruising through expansive glacial valleys skirting the German/Austrian border.
