To compare the technical specifications and features of Yamaha Fazer FZ-1 and BMW F800GT is a good way to find out which one of these motorcycles will better match your style and requirements. When trying to make your mind on the next motorcycle, your personal levels of comfort should be the leading criteria. After comparing one motorcycle versus another and so on, the circle of favourite models will be then eventually narrowed to several ones. Then the most appropriate judgement can be made when each of them is taken for a real ride.

The bigger engine size of Yamaha Fazer FZ-1 in comparison to BMW F800GT doesn't mean that it is more powerful or better performing bike. We can see that the compression ratio of the second of this bikes is 12:1 and is the bigger one. It represents the relation between the biggest and the smallest volume in the combustion chamber while the piston is performing its stroke movement. The bigger compression ratio means better fuel economy comparing engines with the same displacement because the mixture of fuel and air in the combustion chamber burns more effectively.
The better fuel economy of 5.10 l/100km belongs to BMW F800GT compared to the Yamaha Fazer FZ-1's fuel consumption of 6.25 l/100km. 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).
tire sizes The producer of each bike specifies the sizes of its front and rear tyre. Your type of riding is also to be taken into account here. Tires have a code of numbers and letters printed on their sides and these are important to be understood properly when looking for matching tires. The width of the tire measured in millimeters is shown first. Both motorcycles have the same with of their front tires - 120 mm. The second number show the aspect ratio. How many inches is the diameter of the rim - that is what the tird number reveals. A good way to save some time and money is to purchase your motorcycle tires online at competitive price.
BMW F800GT has bigger ground clearance than Yamaha Fazer FZ-1 (165mm vs 135mm). Usually given in millimeters in the technical data sheets, the ground clearance refers to the space between ground level and underside of a motorcycle’s chassis and sometimes is called ride height. That, in other words, is the smallest distance between any mechanical body part of the motorcycle and the surface of the road.
Yamaha Fazer FZ-1 appears to be faster than BMW F800GT with top speed of 246km/h against 201km/h for the other bike. However sources may vary as to whether these top speed parameters are precise or only approximate.Liquid cooled engine of a motorcycle
Both motorcycles are liquid cooled. Motorcycles with liquid cooling operate at narrower temperature ranges. Keeping the operating temperature at a very narrow range allows many engine components to be optimised for these temperatures. 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. Liquid-cooled engines are usually more forgiving because the hot engine has some surrounding coolant to heat up before causing any damage from overheating.
As per their technical specifications both motorcycles have different types of final drive implementation.
chain driven motorcycle The Yamaha Fazer FZ-1is driven by a chain. One of the most economical way to drive horsepower from the engine to the rear wheel of the motorcycle is achieved with the chain drive and therefore it is still the most used among the three options by bike manufacturers. However all chains require keeping an eye on them and proper lubrication when they get dry and cleaning when they get dirty.The BMW F800GT is driven by a belt.
Compression ratio 11.5:1 means that the volume of gas in the cylinder when the piston is at the bottom of its stroke refers to the volume of gas when the piston is at the top of its stroke as 11.5:1. The value of the compression ratio of BMW F800GT is 12:1 based on the information in its technical data and for Yamaha Fazer FZ-1 the ratio is 11.5:1. To avoid engine knocking when compression ratio is high those motorcycles might be recommended to use premium fuel only. Higher compression ratio means bigger pressure of the fuel/air mix in the combustion chamber and better efficiency achieved of its ignition.
Engine oil is among the most important aspects of an engines health. Mineral and part-synthetic engine oils are cheaper when it comes to price in comparison with the most technically advanced synthetic motor oils. The engine oil is to be changed on every 3700 miles (or 6000 kilometers) as a general rule. More kilometers between two oil changes is accepted when synthetic oil is used. Depending on the oil filter it needs to be replaced on each or every two oil changes. The oil capacity of Yamaha Fazer FZ-1 is 3.7 litres and the engine oil of BMW F800GT is 3.1 litres as per their technical specs. The oil capacity information is only to get an idea of how much oil roughly will be needed on oilchange. The best way to pour the exact quantity of oil is to observe the dipstick or the level sight window.
