[moto] BMW S1000RR VS KAWASAKI ZX10R

[luminox™-]

 

Many people have been touting the Kawasaki motorbike, namely the ZX-10R, which has the same power or can exceed its German rival, the BMW S1000RR, so Motorcycle.com proved it with the Dyno test results which showed Kawi's crushing defeat in power and torque.Even though they are both 1000cc, these two motorbikes are both not similar in engine specs like other Japanese motorbikes. The most crucial spec in an engine is the Bore X Stroke of a motorbike engine, because with these two words it can make the motorbike have different power characteristics. The Kawasaki on the ZX-10R 2011 still retains the Japanese characteristic of a stroke at 55.0mm or something similar to other Japanese superbikes such as the CBR1000RR which pegs its stroke at 55.1mm and Yamaha's whiz is slightly shorter at 52.2mm. Unlike the German champion S1000RR who believes more in the shortest stroke of the other superbike, precisely 49.7mm with 80mm Bore.

 

Comparing the power, the ninja was totally defeated from bottom to top ..

It's been noticed that a short stroke has less torque than an engine that has a longer stroke. But it did not happen on these two motors, the error was in accordance with the bore x stroke theory. Supposedly the S000RR which has a shorter stroke should have a lower torque and the ZX-10R should have more torque. This is the strange thing in these two superbikes, maybe a BMW that is too superior or a Kawasaki that does not match the motor specs.

 

Kawasaki should have won torque, but the graph says something else

Let's talk about how the BMW S1000RR can be so violent with its power and torque, first look at the very large diameter of the piston, which is very large, up to 80mm, which means it is very similar to the 2012 motoGp spec which limits the diameter of the piston which cannot exceed 81mm. Dorna making possession of a piston diameter not exceeding 81mm certainly had good reasons for choosing that figure. According to the SLR, the 80mm and 49.7 lift are very precise numbers to strike a balance between power and torque (the cylinder has a capacity of 250cc). This means that with a bore-stroke ratio of 1.6 (80 / 49.7) nothing is sacrificed between power and torque.

 

                                                                                                                  

                                                               BMW S1000R                                                                                                                                                                   KAWASAKI ZX10R

Back to the topic, the S1000RR managed to carve power up to 185.9hp@13.300Rpm higher than the ZX-10R's power which was only 162.8hp@11.900Rpm, the torsiny also lost to the kawi who was only 73.6ft-lb@11,200 compared to 79.3ft.lb@10,500 Rpm. Try to observe the torque of these two superbikes, is there something strange? Of course there is something strange and surprising at the maximum torque notched Rpm, should the BMW S1000R with its short stroke peak torque be above the ZX10R. However, the results of this dyno are again not in accordance with the theory, the S1000RR of torque reaches an earlier peak of 10,500Rpm or 1400Rpm earlier.How is the second report of this Superbike ?? According to SLR, it is extraordinary if you look at the formulation of the power theory. Everything is reversed by the superior specs of the BMW S1000R, it should be broken by successfully gaining more torque and at lower engine speed.
