For small cc cars, it is normal to see the gear stick shaking,
especially 3 cylinders concept! Small cc cars also generated higher
noise level! This is due to......
Lets compare with a 1.6 litre car and do take note of their RPMs.
For a 1.6L car to achieve 100km/h, their RPM is about 2000. But for
a 1L car to achieve that, their RPM is much higher, about 3000.
Same goes with those small cc bikes (super noisy) and larger cc
bikes (honda CBR, R6 and etc produce solid and smoother
sound).....
So the higher the RPM you go, more noise generated! And engine oil
require to change more often, especially for performance
cars!
