Looking at the detailed specifications of both motorcycles BMW K1200GT and Yamaha Fazer FZ-1 is a proper approach to determine which of the two is more likely to match your style of riding and to satisfy your preferences. The decision on your next motorcycle purchase should be all based on your personal preferences for speed, handling and comfort. If you compare the motorcycles you are interested in by analysing their technical specifications, features and pictures, the list of favourite ones could be shortened to just a few models. The most appropriate method of exploring them is to actually ride each of them or at least sit on them to see how they feel.

technical specifications of BMW K1200GTsee data separatelytechnical specifications of Yamaha Fazer FZ-1

Yamaha Fazer FZ-1 has a smaller engine displacement than BMW K1200GT but the size if the engine itself is doesn't mean that the bike is more or less powerful. 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 K1200GT on the contrary can travel 37.3 miles with a gallon. There are two ways of showing the fuel economy of a motorcycle - describing how many miles it can travel with a single gallon of fuel (mpg) or how many litters of fuel it is burning on a 100 kilometer trip (l\100km).
motorcycle tiresEach motorcycle should be fitted with the type of tyres that are specified for it. Your individual riding style is another factor that determines which type is appropriate in your case. 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 aspect ratio of the tire is represented by the second number of the code. How many inches is the diameter of the rim - that is what the tird number reveals. Buying motorcycle tires online can save you precious time and cash.
As per the data sheets BMW K1200GT has a bigger ground clearance (180mm) than Yamaha Fazer FZ-1 (135mm). The ground clearance is also called the ride height and that is the distance between the base of the tyre and underside of the motorcycle’s body (the chassis). That, in other words, is the smallest distance between any mechanical body part of the motorcycle and the surface of the road.
BMW K1200GT is the faster of the two with top speed of 253 kilometers per hour against the max speed of 246 km/h specified to its opponent Yamaha Fazer FZ-1. However sources may vary as to whether these top speed parameters are precise or only approximate.Liquid cooled motorcycle engine
Those two motorcycle use the same cooling system - liquid. Motorcycles with liquid cooling operate at narrower temperature ranges. Therefore liquid cooled motors can run with carburetion set to burn all the fuel in the mixture. The circulation of the coolant from the radiator to the engine is helped by the water pump. 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. However the water pump, the thermostat, the radiator and all the linking gear makes it a bit more complex.
As per their technical specifications both motorcycles have different types of final drive implementation.
motorcycle with chain final drive One of these two motorcycles (the Yamaha Fazer FZ-1) is driven by a chain. Chain drives are by far the most popular final drive technology in the history of motorcycles and are the most economical way to drive power from the engine to the rear wheel. The down points of the chain drive are the frequent maintenance required as it needs to be regularly cleaned and oiled. Besides it is not as smooth as a shaft or belt drive.The BMW K1200GT 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. As mentioned in the information of their technical data the values of the compression ratios are 13:1 for BMW K1200GT and 11.5:1 for Yamaha Fazer FZ-1. To avoid engine knocking when compression ratio is high those motorcycles might be recommended to use premium fuel only. It plays a big role in engine efficiency because bigger compression ratio means better thermal efficiency and more mileage with the same amount of gas.
Motorcycle oil is one of the most important components that keeps the engine running smoothly. Mineral and part-synthetic engine oils are cheaper when it comes to price in comparison with the most technically advanced synthetic motor oils. As a general rule it should be changed on every 6000 kilometers or 3700 miles. With synthetic oil though you can run as far as 8000 kilometers (5000 miles). Some oil filters can be replaced on every second oil change while others are to be replaced on each oil change. Both motorcycles have different oil capacity according to the technical specs - 3.8 litres for BMW K1200GT and 3.7 litres for Yamaha Fazer FZ-1. The oil capacity information is only to get an idea of how much oil roughly will be needed on oilchange. The proper amount of oil needed is best judged while observing the reading on the level sight window (or the dipstick).
