BMW K1200GT is a sport-bike touring made by BMW. K1200GT second generation, introduced in 2006, using essentially the same inline-4 engine as the BMW K1200S sportbike, who holds the world speed record in 2005 for the class at 173.57 mph (279.33 km / h), and K1200R. The new model is lighter and stronger than the first generation K1200GT, which was introduced in the standard include 2003.Fitur adjusted seat, handlebars, integral ABS, panniers and electronically adjustable screen. Options available include: electronic suspension adjustment (ESA), xenon lights, on board computer including oil level warning, automatic stability control (ASC), hot seat, heated hand grips, tire pressure monitoring (TPM), cruise control and alarm anti theft in end of 2008, K1300GT replaced by K1200GT larger displacement, which displays a large 136 cc engine produces 175 bhp (130 kW) and 103 lb · ft (140 N · m) of torque.

New bike also features improved optional ESA II electronic suspension adjustment, conventional single indicator switch and hidden bar.Inline crash-four engine or a straight-four engine four-cylinder internal combustion engine with four cylinders mounted in a straight line or plane along the cylinder block . Single-cylinder banks can be oriented either in vertical or inclined plane with all pistons driving a common crankshaft. Which tends, sometimes called side-four. In the chart specifications or when an acronym is used, inline-four engine I4.K listed as 1200 GT is the successor to the existing K 1200 GT and is based on an innovative engine technology K 1200 K 1200 S and R. second-generation GT offers high-class driving dynamics, the key feature here is the fact that the engine especially designed for high torque. This makes for the highest performance rate and maximum agility: performance sports touring bike would be more than kW/150 bhp 110.

Similarly, chassis components leave anything you want. K 1200 GT has the same technical basis as K 1200 S and offers customers the control Duolever front wheels, for rear wheel suspension Paralever control and power adjustable buffer (ESA) as an optional extra. GT deserves the name "Gran Turismo" is unlike any other. The standard features include an adjustable seat and handlebar. Windshield can be adjusted electronically according to individual preferences. Other equipment features a pannier system and BMW Motorrad Integral ABS in the integral version. BMW Motorrad also offers tailor-made variety of special equipment and a new K aksesoris.1200 GT offers perfect wind and weather protection and an optimal driving machine for touring and long distance. But it was surprisingly small and very elegant in-four appearance. Inline layout is a simple design in perfect primary balance, and confer a degree of mechanical simplicity that made him popular for economy. But car, apart from simplicity, it suffers the imbalance that causes secondary vibrations small in the smaller engines. This vibration got worse as the size and engine power increased, so the more powerful engine used in larger cars are generally more complex designs with more than four cylinder. Displacement inline engine configuration is most common in the car with a displacement up to 2 , 4 liters. Ordinary "practical" limit displacement inline-four engine in a car is about 2.7 liters. However, Porsche uses 3.0-liter four in the 944 S2 and the 968 sports car, and Rolls Royce produced a 4-cylinder 2838cc engine with basic dimensions of 3.5 inch diameter cylinder and 4.5-inch stroke (Rolls Royce B40).

Classic and Antique vehicles tend to have a larger displacement to develop horsepower and torque. Model A Ford was built with 3.3-liter inline four-cylinder machine. Four diesel engine, which is lower than the revving gasoline engines, often exceeding 3.0 liters. Mitsubishi still use 3.2-liter four-cylinder turbodiesel in the Pajero (called Shogun or Montero in certain markets), and Tata Motors employs 3.0-liter four-cylinder diesel in the Sumo Spacio and Victa.Toyota B series diesel engines vary in the displacement 3.0 -- 4.1 liters. Largest machine in the circuit used in the Mega Cruiser.

Larger four-cylinder engines used in industrial applications, such as small trucks and tractors, are often found with a displacement up to about 4.6 liters. Diesel engine for quiet, marine and locomotive use (which run at low speed) are made in sizes much big. Displacement can also be very small, such as those found in cars sold in the Japanese kei, such as Subaru EN series; engine started out in 550 cc and now with 660 cc, with variable valve timing, DOHC engine and cause superchargers that produces 65 PS (48 kW; 64 bhp).

BMW has been busy this year! They have also just announced the K 1200 GT, sport-touring version of the K 1200 S super-sport bike. The motorcycle has a greater reward and a small saddle bag and looks like a fun trip. More information will be posted if available.UPDATE: July 2007 - BMW K 1200 GT has been named as one of the ten motorcycles for 2006 by the editor of Cycle World magazine. On 31 Annual Cycle World Ten Best Bikes awards dinner held this month, the BMW K 1200 GT received the magazine award for Best Sport-Touring Bike, the category for motorcycles that are designed to combine the best elements of sport riding and touring, which includes distance away for a few days. "We are honored to have gained another place in Cycle World's coveted top ten list," commented Arturo Pineiro, Vice President, BMW Motorrad USA. "This is the 13th year BMW has been selected for the ten awards."

Features and Technical Highlights Introducing the new K 1200 GT, BMW Motorrad strengthen worldwide market leadership in the segment of the tour and get a greater role in leading the market.

Following the success of a former model with the same name, the new K 1200 GT opens new dimensions in riding dynamics and quality of long-distance, once again proving the expertise and outstanding competence of white-blue marque.

A special feature K 1200 GT is that this new machine does not require the slightest compromise, but to overcome the contradiction between superior sportiness and high standards of new tur. BMW top-end motorcycle combines maximum agility and dynamic performance with an ideal package for long trips and pleasant travel. To achieve this goal, the development engineers at BMW Motorrad have carried out during the trendsetting running gear and engine technology, the former K 1200 S and K 1200 R straight into this new sport tourists.

Guidance innovative wheel system - Duolever BMW in front and the EVO-Paralever at the rear - make a very significant contribution to the extraordinary and highly dynamic ride characteristics GT. Drive K 1200 power comes from cutting-edge straight-four engine in transverse arrangement , developing maximum output in the GT version of 152 hp (112 kW) and thus currently setting the benchmark in the segment of the tour.

No single competitor in the market offers the same standard of dynamic performance as the new K 1200 GT. Comparison with previous model clearly proves a big step taken by BMW Motorrad with this new engine: K 1200 GT is more powerful (maximum output up to 17%), develops more torque (up to 11%), offers a higher theoretical mileage (up to 17%), and at the same time is lighter (down by 6%), but still capable of carrying higher loads (up to 19%).

It goes without saying that the new GT has all the features you can really expect from BMW touring machine. In particular, it is only suitable for riding with a passenger and covering long distances in comfort and style. Maximum ride comfort is ensured by excellent protection from wind and weather, electric adjustable windscreen, perfect ergonomic design of the driver seat thanks to flexible height adjustment seat and handlebar itself, as well as side cases featured as standar. Last but certainly not least , K 1200 GT also meets the greatest demands in terms of environmental compatibility and safety. Apart from a fully controlled three-way catalytic converter, high-performance EVO brake system with semi-integral ABS anti-lock brakes and electronic immobiliser between natural features offered by new and sophisticated tourists as standard equipment.

Given all the quality and consistency through-and-through, the new K 1200 GT is able to meet even higher standards of comfort is very important to the passionate touring rider, at the same time making exercise heart dyed-in - the-wool motorcycle enthusiasts really ticking. The "GT" abbreviation for Gran Turismo, therefore, describes this BMW sports tourists even more precise than sebelumnya.K new 1200 GT is available in three standard colors will be combined with two contrasting colors in the blankets and chairs, so interpret the character Gran Turismo unique in many ways.

As usual, BMW Motorrad also offers a variety of additional options and special equipment tailored to the new machine and leave what you want. Apart from comfort-oriented features to travel in style, customers have a choice, to mention a few examples, Electronic Suspension Adjustment (ESA), on-board computer, xenon headlights, cruise control, or the BMW Navigator.

The most important feature the new K 1200 GT for short:
- Front-mounted straight-four power unit, cylinder inclined to the angle 55 °
- 1.157 cc, 112 kW/152 hp pada 9.500 rpm, 130 Nm/96 lb-ft) at 7.750 rpm

• Increase the maximum power (+ 17%) 
• High maximum torque (+ 11%)
• Reduction in unladen weight (- 6%)
• High load (+ 19%)
• Tank larger (+ 17%) 
• A longer cruising range of theoretical (+ 17%)

Inline-four engine is much more subtle than one, two, and three-cylinder engine, and this has resulted in it became the economic engine of choice for most cars, although it can be found in several sports car, too. However, inline-four is not a balanced configuration Absolutely. Ashot even-inline-four engines in the primary balance as a piston moving in pairs, and one pair of pistons is always moving up at the same time as the other pair moves downward. However, the acceleration and deceleration larger piston at the top of the rotation of the crankshaft rather than at the bottom, because the rods that connect unlimited long. As a result, two pistons are always accelerate faster in one direction, while the other two are accelerated more slowly in another direction, which leads to secondary dynamic imbalance which causes fluctuating vibration at twice crankshaft speed. This imbalance is tolerable in a small, low displacement, low power configurations, but the vibrations get worse with the increasing size and power.

The reason the piston speed is higher at 180 ° rotation from mid-stroke through the top-dead-center, and back to the middle-stroke, is that the small contribution of the piston's up / down movement of the connecting rod angle changes from here have the same direction with the contribution of the piston's up / down movement of the up / down movement of crank pin. In contrast, during the 180 ° rotation from mid-stroke through bottom-dead-center and back to the middle-stroke piston's small contribution of up / down movement of the rod that connects the change of angle has the opposite direction of the major contributions to the piston's up / down movement of the / down movement of the crank pin.most  Inline-four engines below 2.0 liters in displacement rely on the damping effect of their engine mounts to reduce vibration to an acceptable level. In the 2.0-liter, most modern inline-four engine now uses a balance shaft to eliminate second-order harmonic vibration. In a system that was discovered by Dr. Frederick W. Lanchester in 1911, and popularized by Mitsubishi Motors in the 1970s, an inline-four engine using two-axis balance, spun counterclockwise direction twice crankshaft speed, to compensate for differences in piston speed. However, in the past, there much larger sample inline-fours without balance shafts, such as the Citroën DS 23 2347 cc engine that is derived from the Traction Avant engine, in 1948 Austin 2660 cc engine used in the Austin-Healey 100 and the Austin Atlantic, flathead engine 3.3 liter used in the Ford Model A (1927), and 2.5 liter GM Iron Duke engine used in a number of American cars and trucks. Soviet / Russian Volga GAZ UAZ cars and SUVs, vans and trucks that use large-bore aluminum inline-four engine (2.5 or newer 2.9-liter) without balance shafts in the 1950s-1990s.

These machines are generally the result of a long process of gradual evolution and their strength remains low compared with their capacity. However, the army increased with the square of the speed of the engine-ie, twice the rate of vibration makes four times worse, so the modern high-speed inline-fours have more need to use a balance shaft to offset vibration. Four cylinder also has problems in that the strength of the smooth blows from the piston do not overlap. With four cylinders and four cycles to complete, each piston to complete its power stroke and came to a complete stop before the next piston can start a new power stroke, so that the gap between each power stroke and a pulsed power delivery. In engines with more cylinders, the power stroke overlap, which gives them the power delivery smoother and less vibration than four can be achieved. As a result, six and eight cylinders are generally used in more expensive luxury cars.

The smallest production car inline-four engine-powered 1961 Mazda Carol P360 kei car. Displacing only 358 cc, OHV Mazda is a conventional but tiny pushrod engines. Honda produced, 1963-1967, a 356 cc inline-four engines for the T360 truck. Inline-four engine is built into the 250 cc, for example in the Honda CBR250.

Most inline-four engine, however, has more than 0.7 liters in displacement. Practical upper limits could be placed in the range of 2.5 liters for the production cars contemporary. Larger engine (up to 4.5 liters) had been seen in racing and light trucks in use, mainly using diesel fuel (example is the Mercedes-Benz MBE 904). The use of balance shafts allowed Porsche to use a 3.0 liter (2990 cc) inline-four engines on the first road car in the 944 S2 (1989-1991), but the greatest of modern non-diesel is a plain 3.2-liter (3188 cc) 195 in the year 1961 this Tempest. When Pontiac, one of the largest inline-four engine is a 2.89-liter 421 engine UMZ Series UMZ (Russian machine).

In the early 20th century, larger engine, both on the street cars and sports cars. Because there is no displacement limit rules, producers take the liberty to increase the size of the engine. In order to achieve power over 100 horsepower (75 kW), most engine builders only increased displacement, which can sometimes reach more than 10.0 liters. One of the largest inline-fours from the time that De Dietrich 17,000 cc engine. Cubic with a capacity of more than two times the size of 500 CID Cadillac's 8.2 liter V8 engine, which is regarded as the greatest engine of the type in the 1970s. This machine is running at very low rpm, often less than the maximum 1500 rpm, and has a certain output of about 10 hp / L. U.S., both agricultural and industrial tractors major industries rely on four-cylinder power units until the early 1960s, when the six-cylinder into good design. International Harvester built a large 5.7 liter (350 CID) four cylinder for the WD-9 tractor series.
