A good way to figure out whether BMW S1000RR or Yamaha Fazer FZ-1 is better matching your personal style and requirements is to compare their specifications and features in details. Your choice of motorcycle should be all about your individual preferences and comfort level. After comparing one motorcycle versus another and so on, the circle of favourite models will be then eventually narrowed to several ones. A good way to find the most suitable one among them would be to sit on each of them and if possible ride it for a while.

technical specifications of BMW S1000RRsee data separatelytechnical specifications of Yamaha Fazer FZ-1

The bigger engine size of BMW S1000RR 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 is the ration of the volumes in the cylinder in two stages of the stroke when the piston is at the lowest and then at the highest point in the cylinder. 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 BMW S1000RR which can travel 37.9 miles with one gallon of fuel. Yamaha Fazer FZ-1 on the contrary can travel 37.6 miles with a gallon. When measured in mpg the fuel economy shows how many miles can be traveled with a gallon of fuel. Alternatively when measure in l\100km it shows the fuel consumption in litters per 100 kilometer trip.
how to buy motorcycle tires Motorcycle tyres come in variety of sizes and these sizes are strongly specified for each model. Another considerable factor here is your own riding style. You need to know what the code designators printed on the tire mean in order to be able to find the proper size for your bike. The width of the tire measured in millimeters is shown first. Both motorcycles BMW S1000RR and Yamaha Fazer FZ-1 have the same width of their tires - 120 mm for the front tire and 190 mm for the rear one. 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.
The ground clearance (ride height) of Yamaha Fazer FZ-1 is 135mm and is smaller than the clearance of BMW S1000RR which is 140mm. 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). 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 S1000RR is the faster one with 305km/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.Liquid cooled engine of a motorcycle
Those two motorcycle use the same cooling system - liquid. The tiny variations of the operating temperatures are one of the significant advantages of the liquid cooled motorcycles. Keeping the operating temperature at a very narrow range allows many engine components to be optimised for these temperatures. The liquid (coolant) is forced by the water pump to circulate from the radiator to the engine and back. A fan is turned on if needed by a thermostat to draw more air over the radiator in case the motorcycle slows down. Finally this type of cooling makes it is easier to meet emissions and noise regulations and increase power output.
final drive implemented with chain Chain final drive is used with both motorcycles - the BMW S1000RR and the Yamaha Fazer FZ-1. 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. Many bikers may complain of the need of constant care though. Since the chain is exposed to dust, sun and rain it needs to be periodically cleaned and properly lubricated.
Compression ratio Imagine an engine's piston is at the bottom of its stroke (step one) and moves up compressing the gas in the cylinder till it reaches its top position of the stroke (step 2). The compression ratio is the ration of the volume in step one over the volume in step two. Its value for BMW S1000RR is 13:1 and for Yamaha Fazer FZ-1 is 11.5:1 based on the technical data of the motorcycles. 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.
The good quality of the engine oil is an important factor in keeping the motorcycle in peak condition. Engine oils are different types as synthetic, mineral, part-synthetic and they all come at their price and qualities. It is commonly accepted engine oil to be changed on every 3700 miles (6000 kilometers). The quality of the synthetic oil allows up to 5000 miles (8000 km) between oil changes. Replacing the oil filter is also to be considered on each engine oil change. The oil capacity of BMW S1000RR is 3.9 litres and the engine oil of Yamaha Fazer FZ-1 is 3.7 litres as per their technical specs. When changing the oil it is advisable to put less than the specified oil capacity and to check the level. Pouring exactly the proper amount of oil needed is achieved by observing the level sight window or the dipstick marks.
