motorcycle reviews: 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. ![]() 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. ![]() ![]() 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). |
