The detailed comparison between Ducati Street Fighter S and Yamaha Fazer FZ-1 can help you decide which one of them will suit you better. Your choice of motorcycle should be all about your individual preferences and comfort level. A good way to narrow the circle of favourite bikes is to compare their technical specifications and select just a few that are really matching your style and needs. The best way to explore them is to actually sit on these bikes and check how much comfort you get with each of them.
The bigger engine size of Ducati Street Fighter S 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 12.5:1 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 Ducati Street Fighter S which can travel 44.4 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. ![]() Ducati Street Fighter S has bigger ground clearance than Yamaha Fazer FZ-1 (150mm vs 135mm). 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. Ducati Street Fighter S appears to be faster than Yamaha Fazer FZ-1 with top speed of 248km/h against 246km/h for the other bike. However sources may vary as to whether these top speed parameters are precise or only approximate. ![]() ![]() 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. 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 Ducati Street Fighter S the ratio is 12.5:1. Motorcycles with higher compression ratio may be recommended to use premium fuel only in order to avoid engine knocking. If you got a motorcycle with a greater compression ratio for its specific engine it is getting better fuel economy than it would if it had a lesser compression ratio. To keep the engine in good health it is important to observe the good qulity and proper level of the motor oil. Engine oils are different types as synthetic, mineral, part-synthetic and they all come at their price and qualities. The engine oil is to be changed on every 3700 miles (or 6000 kilometers) as a general rule. More kilometers between two oil changes is accepted when synthetic oil is used. The oil filter needs to be replaced too and that is usually to be done with the oil change. Both motorcycles have different oil capacity according to the technical specs - 2.8 litres for Ducati Street Fighter S 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. Observing the currrent level on the dipstick or the level sight window is the best way to pour the proper amount of oil. |
