The bigger engine size of BMW K1200R Sport in comparison to Yamaha Fazer FZ-1 doesn't mean that it is more powerful or better performing bike. The first bike has the advantage of greater compression ratio of 13:1 than the other one. This parameter shows how the volume in the engine cylinder when the piston is at the bottom end relates to the volume when the piston is at the top end. When the mixture of air and fuel in the combustion chamber has bigger pressure (higher compression ratio) when it is ignited then it burns more effectively and therefore these bikes tend to have better fuel economy (comparing engines with equal displacement).
The bike with a better fuel economy is the Yamaha Fazer FZ-1 which can travel 37.6 miles with one gallon of fuel. BMW K1200R Sport on the contrary can travel 36.8 miles with a gallon. Miles per gallon (mpg) is one way of describing the fuel economy of a motorcycle and liters per 100 kilometers (l/100km) is another.

Each motorcycle should be fitted with the type of tyres that are specified for it. Your type of riding is also to be taken into account here. To choose the right tire size firstly you need to understand the meaning of the numbers printed on the size of the tire. The first number is the width of the tire in millimeters. Both motorcycles have the same with of their front tires - 120 mm. The second number show the aspect ratio. And the third number indicats the diameter of the rim in inches. Since many internet stores are offering motorcycle tires it is an easy way to get proper pair of tires online at reasonable price.
BMW K1200R Sport has a better ground clearance of 180mm ( for Yamaha Fazer FZ-1 it is 135mm). The ride height is the other name of the parameter ground clearance which refers to the measure from the tyre base to the underside of the cassis of a motorcycle. In other words that is the shortest distance between the road surface and the lowest mechanical part of the motorcycle.
Comparing the top speed values of both motorcycles we can see that BMW K1200R Sport is the faster one with 272km/h. As per the technical data of Yamaha Fazer FZ-1 it would be behind it on the highway with 246km/h. However sources may vary as to whether these top speed parameters are precise or only approximate. engine of a liquid cooled motorcycle

Both motorcycles are liquid cooled. Liquid-cooled engines have a narrower range of operating temperatures compared to the air-cooled ones. Therefore the liquid-cooled engine runs more efficiently and consistently. The main principle is circulation of the liquid between the radiator and the engine. If the motorcycle slows down to a point where the air flowing through the radiator is not enough to lower the temperature of the coolant to the needed level, a thermostat will typically switch an electric fan on to increase the air flow through the radiator. A liquid-cooled engine happens to be quieter than the air-cooled one because all that liquid that surrounds the engine deadens mechanical noise.
As per their technical specifications both motorcycles have different types of final drive implementation.
motorcycle with chain final drive

The final drive of the Yamaha Fazer FZ-1 is chain. Chain final drives are known for their simplicity and efficiency in driving power from the engine to the rear wheel of the motorcycle and are one of the most popular final drive options by far. However they are not as smooth as belts and shafts and also require frequent care like cleaning and keeping the chain properly lubricated.The BMW K1200R Sport is driven by shaft.
compression ratio is a value that represents the ratio of the volume of gas in the cylinder when the piston is at the lowest point it is ever gonna go down and the volume of gas when the piston is at its highest point. The compressio ratio of Yamaha Fazer FZ-1 is 11.5:1 and it is 13:1 for BMW K1200R Sport according to the motorcycles technical data above. Premium fuel might be recommended for some motorcycles with high levels of compression ration in order to avoid engine knocking. Engines with higher compression ratio are more energy efficient because they are able to extract more mechanical energy from a certain amount of fuel.
One of the most important aspects of the basic level of maintenance of a motorcycle is the engine oil. Synthetic engine oils are considered the most technically advanced one and are more expensive than the mineral oils which come at lower price. It is commonly accepted engine oil to be changed on every 3700 miles (6000 kilometers). With synthetic oil though you can run as far as 8000 kilometers (5000 miles). The oil filter needs to be replaced too and that is usually to be done with the oil change. BMW K1200R Sport takes 3.8 litres of engine oil. The technical specs of Yamaha Fazer FZ-1 determines its oil capacity to be 3.7 litres. When changing the oil it is advisable to put less than the specified oil capacity and to check the level. Observing the currrent level on the dipstick or the level sight window is the best way to pour the proper amount of oil.
