technical specifications of Kawasaki Versys 650see data separatelytechnical specifications of Yamaha Fazer FZ-1

The bigger engine size of Yamaha Fazer FZ-1 in comparison to Kawasaki Versys 650 doesn't mean that it is more powerful or better performing bike. The second bike has the advantage of greater compression ratio of 11.5:1 than the other one. This represents the biggest volume of the cylinder when the piston is located at the lowest point of the stroke compared to the minimum volume of the cylinder when the piston is at the highest point of the stroke. 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 Kawasaki Versys 650 which can travel 45.2 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 tiresEach motorcycle should be fitted with the type of tyres that are specified for it. Picking the proper type that matches your individual style of riding is very essential. 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. The width of the tire measured in millimeters is shown first. Both motorcycles have the same with of their front tires - 120 mm. The profile of the tire is revealed by the second number. The third number shows the size of the rim - its diameter measured in inches. Looking online for motorcycle tires is a good way to easily find the right size at low price.
The ground clearance (ride height) of Yamaha Fazer FZ-1 is 135mm and is smaller than the clearance of Kawasaki Versys 650 which is 170mm. 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. To say it shortly, this is the smallest of the measures between the road surface and any mechanical part of the motorcycle.
The top speed of 246km/h makes Yamaha Fazer FZ-1 the faster of the two motorcycles. The other one (Kawasaki Versys 650) can achieve a maximum speed of 197km/h according to its technical specifications. However sources may vary as to whether these top speed parameters are precise or only approximate.Motorcycle with liquid cooling system
Kawasaki Versys 650 is liquid cooled and so is the Yamaha Fazer FZ-1. The pretty constant ranges of operating temperature are typical for the liquid cooled engines. 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. Liquid-cooled engines are usually more forgiving because the hot engine has some surrounding coolant to heat up before causing any damage from overheating.
final drive implemented with chain Both motorcycles Kawasaki Versys 650 and Yamaha Fazer FZ-1 have the same final drive - 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. 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.
Compression ratio 10.8:1 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 10.8:1. As mentioned in the information of their technical data the values of the compression ratios are 10.8:1 for Kawasaki Versys 650 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. Engines with higher compression ratio are more energy efficient because they are able to extract more mechanical energy from a certain amount of fuel.
The good quality of the engine oil is an important factor in keeping the motorcycle in peak condition. There are different types at different prices on the market - mineral, highperformance, all-purpose part-synthetic and synthetic oil. 3700 miles (6000 km) between oil changes is widely accepted rule. The quality of the synthetic oil allows up to 5000 miles (8000 km) between oil changes. A good practice is to replace the oil filter with each or every second oil change. According to the technical specs the engine oil capacity is 1.9 litres for Kawasaki Versys 650 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 exact amount of oil you pour in is to be judged by the current level shown on the oil level sight window or dipstick.
