Difference between "Inline Twin" and "Parallel Twin"?

Yes, they're the same

Yes, they're the same

a very good thread.

so the parallel twin and inline twin are the same with different names?

i read the thread from top to bottom, but i couldnt understand some posts, because i am technically not up to mark...

Yes they are; if my previous posts are confusing, that was when I started.

I hope the links below helps in understanding the engine configurations...

Re: Difference between "Inline Twin" and "Parallel Twin"?

Parallel and inline twin are both the same, the crankshaft degree determine the way in which the cylinders move. The possible configurations for a parallel twin are 180,360 and 720 degree. For a 360 both cylinders will rise and fall at the same time, in a 180 configuration, one will rise and the other will fall, for a 270 one cylinder follows three quarters of the cycle of the other.
Btw, the Ninja uses a 180 degree configuration so one of the cylinders goes up while the other falls down.

Re: Difference between "Inline Twin" and "Parallel Twin"?

Concept of 180 degree movement & 360 degree movement looks practical to me but could not understand the actual difference

What in case of v-twin and flat twin engines, I think its the same as parallel twin, right?

One more thing is that if it is a 180 degree movement then a two cylinder engine can also become inline two, right?

Re: Difference between "Inline Twin" and "Parallel Twin"?

In a "V" twin cylinder the piston and cylinder angle determines the configuration...In a flat twin the 2 cylinders are flat in opposite sides opposed to each other like in most BMW bikes...in this case the cylinders are 180 degrees opposed .
