The BMW R1200S is a luxury sports motorcycle produced by BMW Motorrad from 2006 to 2007.
44-646: Compared to the BMW R1100S which it succeeded, the R1200S was 13 kg (29 lb) lighter, and (with a compression ratio raised from 11.3:1 to 12.5:1) it was 25% more powerful with a "hexhead" motor rated at 122 horsepower (91 kW). Much of the weight saving was down to a new trellis-type frame which replaced the massive alloy frame of the R1100S. The R1200S thus had superior handling, improved braking, higher power output, greater ground clearance, and sport ergonomics. Although
88-511: A Land Rover , the drive shaft to the front axle is noticeably shorter and more steeply articulated than the rear shaft, making it a more difficult engineering problem to build a reliable drive shaft, and which may involve a more sophisticated form of universal joint. Modern light cars with all-wheel drive (notably Audi or the Fiat Panda ) may use a system that more closely resembles a front-wheel drive layout. The transmission and final drive for
132-549: A quarter mile time of 11.1 seconds. In 2008 the R1200S was superseded by the double overhead camshaft HP2 Sport . At 178 kg (dry) and 128 hp, the HP2 is even lighter and more powerful than the R1200S upon which it is based; (and compared to the R1100S, the HP2 is 30 kg lighter and 30 hp more powerful). The HP2's dohc engine was the most powerful "oilhead" design before BMW adopted liquid cooling for some of its flat twins in 2013. BMW R1100S The BMW R1100S
176-504: A belly-pan fairing. The R1100S is 27 kg (60 lb) lighter and 8 hp (6.0 kW) more powerful than the BMW R1100RS from which it was derived, but at 229 kg (505 lb) (wet), it is still no lightweight. Nevertheless, What Bike? magazine stated: "With underseat exhaust and plenty of ground clearance, the BMW is helped by the lack of dive under braking and makes up metres on
220-402: A chain-drive in bicycles for the past century, never becoming very popular. A shaft-driven bicycle (or "Acatène", from an early maker) has several advantages and disadvantages: Drive shafts are one method of transferring power from an engine and PTO to vehicle-mounted accessory equipment, such as an air compressor . Drive shafts are used when there is not enough space beside the engine for
264-429: A drive shaft is used to transfer a certain speed or torque from the internal combustion engine to a dynamometer . A "shaft guard" is used at a shaft connection to protect against contact with the drive shaft and for detection of a shaft failure. At a transmission test stand a drive shaft connects the prime mover with the transmission. An automotive drive shaft can typically last about 120,000 kilometres. However, if
308-401: A drive shaft. In 1899, Bukey used the term to describe the shaft transmitting power from the wheel to the driven machinery by a universal joint in his Horse-Power . In the same year, Clark described his Marine Velocipede using the term to refer to the gear-driven shaft transmitting power through a universal joint to the propeller shaft. Crompton used the term to refer to the shaft between
352-406: A ratchet handle similar to a car's hand brake or parking brake , as opposed to an air brake button or lever. Risk factors for drivers include parking on a steep slope when heavily loaded, not applying the brake with enough force, changing the load or load balance while parked on a slope, or parking where one side of the vehicle is able to slip. Using chocks on the wheels is one way of preventing
396-468: A rear-mounted transaxle . In some non-Porsche models, this places the clutch and transmission at the rear of the car and the drive shaft between them and the engine. In this case the drive shaft rotates continuously with the engine, even when the car is stationary and out of gear. However, the Porsche 924/944/928 models have the clutch mounted to the back of the engine in a bell housing and the drive shaft from
440-456: A stonking and attractive all-rounder, if not quite the sports bike BM intended…". A special edition model was the R1100S Sport , which was a standard R1100S fitted with an optional "Sport" pack comprising stiffer suspension via a taller rear monoshock, a steering damper, and a wider rear wheel and tyre. Bike magazine commented: "The basic R1100S is good value, but we're not convinced that
484-538: Is a sports motorcycle that was manufactured by BMW Motorrad between 1998 and 2005. Introduced some 25 years after the R90S , the company's first sports bike, the R1100S was the first BMW bike having clip-on handlebars , rearset footrests and a removable cowl to cover the pillion seat. Producing nearly 100 hp, it has been described as a "sporty sports-tourer ". The engine is a flat-twin "oilhead" that has air-cooled cylinders but oil-cooled heads . Derived from

#1732872836355528-438: Is a component for transmitting mechanical power , torque , and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them. As torque carriers, drive shafts are subject to torsion and shear stress , equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear
572-565: Is derived from the BMW K1200RS. Far from being a touring overdrive, the top gear gives 20 mph per 1,000rpm, so at 80 mph the engine turns at 4,000rpm. In addition to using the engine as a stressed member , the R1100S has a composite aluminum frame to which the suspension components are attached. The front suspension is BMW's patented Telelever , with long telescopic fork sliders containing neither springs nor damping. In order to minimize "fork dive" , braking forces are taken back to
616-404: Is known as the tail shaft. The Shay , Climax and Heisler locomotives, all introduced in the late 19th century, used quill drives to couple power from a centrally mounted multi-cylinder engine to each of the trucks supporting the engine. On each of these geared steam locomotives , one end of each drive shaft was coupled to the driven truck through a universal joint while the other end
660-434: Is needed to turn the power 90° from the shaft to the rear wheel, losing some power in the process. BMW has produced shaft drive motorcycles since 1923; and Moto Guzzi have built shaft-drive V-twins since the 1960s. The British company, Triumph and the major Japanese brands, Honda , Suzuki , Kawasaki and Yamaha , have produced shaft drive motorcycles. Lambretta motorscooters type A up to type LD are shaft-driven
704-460: Is the propeller shaft that serves to transmit the drive force generated by the engine to the axles. Several different types of drive shaft are used in the automotive industry: The slip-in-tube drive shaft is a new type that improves crash safety. It can be compressed to absorb energy in the event of a crash, so is also known as a "collapsible drive shaft". These evolved from the front-engine rear-wheel drive layout. A new form of transmission called
748-550: The BMW R1100RS , the 1,085 cc fuel-injected eight-valve engine is tuned for a maximum output of 98 horsepower (73 kW) at 8,400rpm. At the time of its introduction, it was BMW's most powerful boxer engine ever made, and the first mated to a six-speed transmission. The ohv engine has chain-driven camshafts mounted in the cylinder heads, operating the valves via short pushrods and rocker arms. Engines produced after 2003 had dual ignition , with two spark plugs per cylinder. The compact close-ratio six-speed transmission
792-412: The hull . The thrust, the axial force generated by the propeller, is transmitted to the vessel by the thrust block or thrust bearing, which, in all but the smallest of boats, is incorporated in the main engine or gearbox. Shafts can be made of stainless steel or composite materials depending on what type of ship will install them. The portion of the drive train which connects directly to the propeller
836-407: The transfer case was placed between transmission and final drives in both axles. This split the drive to the two axles and may also have included reduction gears, a dog clutch or differential. At least two drive shafts were used, one from the transfer case to each axle. In some larger vehicles, the transfer box was centrally mounted and was itself driven by a short drive shaft. In vehicles the size of
880-552: The NSU Prima scooter is also shaft-driven Motorcycle engines positioned such that the crankshaft is longitudinal and parallel to the frame are often used for shaft-driven motorcycles. This requires only one 90° turn in power transmission, rather than two. Bikes from Moto Guzzi and BMW, plus the Triumph Rocket III and Honda ST series all use this engine layout. Motorcycles with shaft drive are subject to shaft effect , where
924-492: The R1200S to its predecessor this way: "As an oddball track motorcycle it works, but as an accomplished all-rounder it falls short of the standards set by the R1100S that preceded it." In 2008 the R1200S was itself superseded by the double overhead camshaft HP2 Sport .

SECTION 20
#1732872836355968-552: The automobile company Panhard et Levassor which patented it. Most of these vehicles have a clutch and gearbox (or transmission) mounted directly on the engine, with a drive shaft leading to a final drive in the rear axle. When the vehicle is stationary, the drive shaft does not rotate. Some vehicles (generally sports cars, such as the Chevrolet Corvette C5 / C6 / C7 , Alfa Romeo Alfetta and Porsche 924/944/928 ), seeking improved weight balance between front and rear, use
1012-454: The chassis climbs when power is applied. This effect, which is the opposite of that exhibited by chain-drive motorcycles, is counteracted with systems such as BMW's Paralever , Moto Guzzi's CARC and Kawasaki's Tetra Lever . On a power-driven ship, the drive shaft, or propeller shaft, usually connects the propeller outside the vessel to the driving machinery inside, passing through at least one shaft seal or stuffing box where it intersects
1056-419: The clutch output, located inside of a hollow protective torque tube, transfers power to the rear mounted transaxle (transmission + differential). Thus the Porsche driveshaft only rotates when the rear wheels are turning as the engine-mounted clutch can decouple engine crankshaft rotation from the driveshaft. So for Porsche, when the driver is using the clutch while briskly shifting up or down (manual transmission),
1100-472: The earlier R1100S has perhaps proved the more successful design. Motor Cycle News said of the R1200S: "As an oddball track motorcycle it works, but as an accomplished all-rounder it falls short of the standards set by the R1100S that preceded it." However, the owners’ comments attached to this article viewed the R1200S much more favourably. The 2006 BMW R1200S was reported to have a 0-60 time of 3.5 seconds, and
1144-475: The engine can rev freely with the driver's accelerator pedal input, since with the clutch disengaged, the engine and flywheel inertia is relatively low and is not burdened with the added rotational inertia of the driveshaft. The Porsche torque tube is solidly fastened to both the engine's bell housing and to the transaxle case, fixing the length and alignment between the bell housing and the transaxle and greatly minimizing rear wheel drive reaction torque from twisting
1188-498: The entry to corners. Mid-corner speed is superb, but it's on the exit that the air-cooled twin shows its short legs. Stick to the road, though, and the R1100S is a great place to be". Motor Cycle News ( MCN ) later reviewed the R1100S, stating: "The BMW R1100S is now starting to be regarded as something of a classic, especially in BoxerCup form. Classy styling, VFR -esque comfort and versatility plus BMW quality and residuals make for
1232-434: The frame via a pivoting wishbone. A monoshock on this wishbone copes with springing and damping. The rear suspension comprises BMW's " Paralever ", a single-sided swinging arm encompassing shaft drive . The Paralever mounts directly to the frame instead of to the gearbox as on earlier oilheads. A reviewer reported: “The result is greater frame rigidity and better handling". A detachable tubular subframe supports
1276-448: The front axle are combined into one housing alongside the engine, and a single drive shaft runs the length of the car to the rear axle. This is a favoured design where the torque is biased to the front wheels to give car-like handling, or where the maker wishes to produce both four-wheel drive and front-wheel drive cars with many shared components. The automotive industry also uses drive shafts at testing plants. At an engine test stand ,
1320-572: The high spec Sport version offers any real benefit for road riders". A more expensive track-day version of the BMW R1100S, the BoxerCup Replika (or "BCR"), was available from 2003 to 2005. The BCR had twin Laser under-seat exhausts, braided brake lines, carbon-fibre cylinder head protectors, a carbon-fibre oil-catcher bellypan, uprated Öhlins suspension, and a shorter paralever torque arm which raised
1364-431: The instrumentation was updated, the bike retained the unconventional BMW-system indicator switches (one on either side). Factory options included front and rear Öhlins shock absorbers, switchable ABS , a light weight Akrapovič muffler, expandable locking luggage, heated grips, a solo tail piece, a Tire-pressure monitoring system and a wider 6" rear wheel to accommodate a size 190 tire. Despite these refinements, overall

1408-409: The machine's wheels to the gear train that works the cutting mechanism. In the 1890s, the term began to be used in a manner closer to the modern sense. In 1891, for example, Battles referred to the shaft between the transmission and driving trucks of his Climax locomotive as the drive shaft, and Stillman referred to the shaft linking the crankshaft to the rear axle of his shaft-driven bicycle as
1452-457: The mid-19th century. In Stover's 1861 patent reissue for a planing and matching machine , the term is used to refer to the belt-driven shaft by which the machine is driven. The term is not used in his original patent. Another early use of the term occurs in the 1861 patent reissue for the Watkins and Bryson horse-drawn mowing machine . Here, the term refers to the shaft transmitting power from
1496-478: The rear end to quicken the steering and increase cornering clearance. Later BoxerCup and Sport models had matte black engines, with the cylinders and cylinder heads remaining silver. The raised suspension of the BCR increased cylinder head cornering clearance (compared to the standard R1100RS), but this somewhat compromised the motorcycle for normal town/road use. The BCR came with a standard engine management chip which
1540-468: The rider and passenger. The R1100S has a very substantial half fairing which completely envelops the alloy fuel tank. Both the hugger (after market option) and front fender are made of carbon-fibre. The two-into-one exhaust feeds twin silencers tucked up high beneath the pillion seat, like those on the Ducati 916 . Factory options originally available from BMW included electrically heated grips, ABS brakes and
1584-402: The stress, while avoiding too much additional weight as that would in turn increase their inertia . To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints , jaw couplings , or rag joints , and sometimes a splined joint or prismatic joint . The term driveshaft first appeared during
1628-448: The term drive shaft is restricted to a transverse shaft that transmits power to the wheels, especially the front wheels. The shaft connecting the gearbox to a rear differential is called a "propeller shaft", or "prop-shaft". A prop-shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints. Where the engine and axles are separated from each other, as on four-wheel drive and rear-wheel drive vehicles, it
1672-407: The transaxle in any plane. A drive shaft connecting a rear differential to a rear wheel may be called a half-shaft. The name derives from the fact that two such shafts are required to form one rear axle . Early automobiles often used chain drive or belt drive mechanisms rather than a drive shaft. Some used electrical generators and motors to transmit power to the wheels. In British English ,
1716-468: The transmission of his steam-powered Motor Vehicle of 1903 and the driven axle. The pioneering automobile industry company, Autocar , was the first to use a drive shaft in a gasoline-powered car. Built in 1901, today this vehicle is in the collection of the Smithsonian Institution. An automobile may use a longitudinal shaft to deliver power from an engine/transmission to the other end of
1760-494: The vehicle before it goes to the wheels. A pair of short drive shafts is commonly used to send power from a central differential , transmission , or transaxle to the wheels. In front-engined, rear-wheel drive vehicles, a longer drive shaft is also required to send power the length of the vehicle. Two forms dominate: The torque tube with a single universal joint and the more common Hotchkiss drive with two or more joints. This system became known as Système Panhard after
1804-433: The vehicle experiencing any of the signs below, drivers should get it checked as soon as possible. A cardan shaft park brake works on the drive shaft rather than the wheels. These brakes are commonly used on small trucks. This type of brake is prone to failure and has led to incidents where the truck has run away on a slope, leading to safety alerts being issued. Heavy vehicles that have this type of park brake usually have

1848-550: The vehicle from moving on a slope. Drive shafts have been used on motorcycles since before WW1, such as the Belgian FN motorcycle from 1903 and the Stuart Turner Stellar motorcycle of 1912. As an alternative to chain and belt drives, drive shafts offer long-lived, clean, and relatively maintenance-free operation. A disadvantage of shaft drive on a motorcycle is that helical gearing , spiral bevel gearing or similar
1892-555: Was changed for a modified chip at the first dealer service. Despite the different chip, the Replika claimed no more power than the standard R1100S nor the Sport. The R1100S was superseded in 2006 by the R1200S . The alloy frame of the R1100S was replaced by a lightweight tubular trellis and so, with a tuned engine, the R1200S was 13 kg (29 lb) lighter and 25% more powerful. MCN compared
1936-537: Was powered by the crankshaft , transmission or another truck through a second universal joint. A quill drive also has the ability to slide lengthways, effectively varying its length. This is required to allow the bogies to rotate when passing a curve. Cardan shafts are used in some diesel locomotives (mainly diesel-hydraulics, such as British Rail Class 52 ) and some electric locomotives (e.g. British Rail Class 91 ). They are also widely used in diesel multiple units . The drive shaft has served as an alternative to
