Yamaha Honda Suzuki Kawasaki BMW Harley Davidson Aprilia Ducati Triumph KTM Hyosung
To compare the technical specifications and features of Kawasaki Ninja 250R and Yamaha Fazer FZ-1 is a good way to find out which one of these motorcycles will better match your style and requirements. The decision on your next motorcycle purchase should be all based on your personal preferences for speed, handling and comfort. After comparing one motorcycle versus another and so on, the circle of favourite models will be then eventually narrowed to several ones. 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.

The bigger engine size of Yamaha Fazer FZ-1 in comparison to Kawasaki Ninja 250R doesn't mean that it is more powerful or better performing bike. The first bike has the advantage of greater compression ratio of 11.6:1 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 Ninja 250R which can travel 57.4 miles with one gallon of fuel. Yamaha Fazer FZ-1 on the contrary can travel 37.6 miles with a gallon. The fuel economy of a motorcycle is either measured in mpg or l/100km, the first showing how many miles can be ridden with a gallon of fuel and the second showing how many litters of fuel are consumed on a 100km ride.
tire sizesIf the time to replace your motorcycle tyres has come then you need to find the proper new ones. 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. The second number show the aspect ratio. The third of the code numbers reffers to the size of the rim and it is measured in inches. Buying motorcycle tires online can save you precious time and cash.
Both motorcycle models have the same measure of 135mm for their ground clearance. 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). To say it shortly, this is the smallest of the measures between the road surface and any mechanical part of the motorcycle.
Yamaha Fazer FZ-1 is the bike with higher tested top speed (246km/h). On the other side Kawasaki Ninja 250R can achieve speed of 168km/h on the highway. However sources may vary as to whether these top speed parameters are precise or only approximate.liquid cooling system of a motorcycleThe same method of engine cooling is used on both motorcycles - liquid cooling. 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 circulation of the coolant from the radiator to the engine is helped by the water pump. A thermostat turns on an electric fan to draw more air over the radiator in case the motorcycle slows down and the air flowing through the radiator is not enough to cool the liquid inside it to the desired level. Liquid-cooled engines are usually more forgiving because the hot engine has some surrounding coolant to heat up before causing any damage from overheating.
motorcycle with chain final drive The same final drive (chain) is used with these two bikes Kawasaki Ninja 250R and Yamaha Fazer FZ-1. 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. 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 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. The value of the compression ratio of Yamaha Fazer FZ-1 is 11.5:1 based on the information in its technical data and for Kawasaki Ninja 250R the ratio is 11.6:1. This is actually the relation between the biggest and the smallest capacity of the combustion chamber. 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.
Engine oil is among the most important aspects of an engines health. Synthetic engine oils are considered the most technically advanced one and are more expensive than the mineral oils which come at lower 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. Both motorcycles have different oil capacity according to the technical specs - 1.9 litres for Kawasaki Ninja 250R and 3.7 litres for Yamaha Fazer FZ-1. This oil capacity values are with informative purpose only. The proper amount of oil needed is best judged while observing the reading on the level sight window (or the dipstick).
