technical specifications of Harley Davidson Road King FLHRsee data separatelytechnical specifications of Yamaha Fazer FZ-1

Harley Davidson Road King FLHR has bigger engine size than Yamaha Fazer FZ-1 but this is not a direct indicator for more power or better performance. The second bike has the advantage of greater compression ratio of 11.5:1 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. Harley Davidson Road King FLHR on the contrary can travel 35.1 miles with a gallon. Measuring the fuel economy in mpg shows how many miles of ride are covered by a gallon of fuel and measuring in l/100km shows the average fuel consumption in litters for every 100 kilometers riding.
bike tires The producer of each bike specifies the sizes of its front and rear tyre. Another considerable factor here is your own riding style. The code designators located on the side of each tires is something that you should be aware of if you want to find proper tires for your bike. Firstly the code shows the width of the tire measured in millimeters. After that comes the aspect ration shown by the second number in the code. And the third number indicats the diameter of the rim in inches. Buying motorcycle tires online can save you precious time and cash.
The ground clearance of 135mm is equal for both motorcycle models. The parameter ground clearance refers to the space between the ground and underside of the chassis and is also called ride height of a motorcycle. In simple terms that would be the shortest line among all the lines drawn between the surface of the road and any mechanical part of the motorcycle.
Comparing the top speed values of both motorcycles we can see that Yamaha Fazer FZ-1 is the faster one with 246km/h. As per the technical data of Harley Davidson Road King FLHR it would be behind it on the highway with 170km/h. However sources may vary as to whether these top speed parameters are precise or only approximate.
As per their technical specifications both motorcycles have different types of final drive implementation.
final drive implemented with chain The Yamaha Fazer FZ-1is driven by a chain.Most motorcycles are produced with chain drive because of its economical way to transfer power to the rear wheel and convey the biggest percentage of engine power in that process. 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.The Harley Davidson Road King FLHR is driven by a belt.
Compression ratio - this parameter refers to how the cylinder's space changes from when the piston is down at its lowest point to when the piston is up at its highest point in the stroke. Based on the information from the technical data of the motorcycles the values are accordingly 9.7:1 for Harley Davidson Road King FLHR 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. With internal combustion engines the higher compression ratio allows higher efficiency because the combustion temperature is reached with less fuel.
To keep the engine in good health it is important to observe the good qulity and proper level of the motor oil. Many different types of engine oils are available as minerral, part-synthetic and synthetic and they all come at different price. 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. The oil capacity of Harley Davidson Road King FLHR is 3.8 litres and the engine oil of Yamaha Fazer FZ-1 is 3.7 litres as per their technical specs. The oil capacity here is just to give you a rough idea of how much oil you need on an oil change. Observing the currrent level on the dipstick or the level sight window is the best way to pour the proper amount of oil.
