Cool 2009 Yzf1000r1

Just thought I'd share the new sound. It was pretty cool hearing it at Indy aswell.

You mean it sounds different than every other 1000cc inline four?

Yeah, more like the gear driven Vfours almost but not quite.

What is in the engine configuration would make it sound one bit differently than say a Suzuki GSXR? I don't get it.

Different cylinder firing order.

So the #1 cylinder firing makes a different sound than the #3? Does the #2 make a different sound than the #4? Does one cylinder fire more than the others? Is it in a 'big bang' configuration? I'm still not getting why it would sound any different than any other 1000cc inline four. Unless it is firing more than one cylinder at the same time, it really doesn't matter which one fires when, because they all make the same sound when fired, don't they?

I sence alot of sarcasm in your response, are you trying to start some hugh heated debate on the bigbang theory?

Ok, I'll bite,...
Not sure what makes it sound that much different, dont know if it's something as simple as the exhaust making that certain note, or even if its the different firing order. I would'nt think its the firing order but ya never know, maybe its the flux capaciter.

Just thought I'd post the sound bite, cause it does sound different no matter what's making it sound that way.

All I know is the delivery is much smoother when leaned over at full lean angle. Honda was the first to create the smoother firing order when the 2stroke 500's where being ridden by the likes of Mick Doohan. The delivery of power was so violent the rider would just spin the tire or get spit off.

The call it the "big bang" firing order. Instead of having a steady stream of each cylinder firing sequentially, you fire two and then the other two together. There's a pretty cool article in the November Cycle World about it. The idea is to put "pulses" of power to the tire to allow the grip to recover; similar to what a twin (Duc) does naturally.

Good explanation, firing in line gives it less power pulses rather than the conventional method.
