Is the s1000rr direct injected?

[Obtik6]

Sorry, I've been searching for any info on this, couldn't find anything on the forum about it. except someone talking about most cars going to it. would definitely describe the huge power increase and mpg on such a high performance bike. ill probably find the answers on google before anyone answers this. is the S1000rr direct injected, and VVT(variable valve timing)?? definitely feels like VVT when you hit 9-10k. waiting on my shop manual Thursday to start poking around lol

nope, it does have a velocity stack that changes position.

Nope on both accounts, DI has'nt reached bikes yet and is primarily for reduced emissions, saying that it works well on turbo charged engines as it cools the cylinder allowing high compression ratio's to be used............like 10:1 which was unheard of not so long ago

VVT also no

Absolutely positively....nope

The Motus V4 is the only direct injected bike I can think of off the top of my head.

They WILL eventually have DI (bike) motors, but I don't know that they are close to mass production 14K RPM injectors and processors quite yet.

The variable cam timing bit will be first, and should make things interesting.

DI and diesel!! Now that will be something on motorcycles!

Thanks for the info guys, appreciate it.

Not to start an argument, but i don't believe your info on DI is completely true. reason i asked if the s1000rr was DI is its at a 13:1 ratio, witch is pretty insane and control the heat well. definitely a barely touched technology that's going to explode soon. we were just learning this in auto class last semester, at least 10-20% increase in power and economy, and also help emissions. there saying a DI 4 cylinder motor will be the high class performance motor for even large trucks. lol only could imagine what it would be like on a bike.
(but ultra lean mode can involve ratios as high as 65:1)

I wouldn't wish for VVT. The only bike I know of which tried that was the VFR800 VTEC which got mixed reviews at best. A very noticeable step in power at 7000 rpm was the main issue. It's like getting a kick in the pants you were not expecting whilst cranked over half way round a bend.

I am a senior mechanical engineer (though not in autos), and I too believed the main reason many car manufacturers are going to DI is to reduce emissions and increase efficiency.

completely agree, everything is emissions and safety anymore. cringe at the thought of OBD 3 in 2012... nothing more satisfying than a chip that cancels out all OBD without a engine code lol. i just remember the way the teacher talked about DI in lecture, we all just about creamed in our pants from the potential.

what is WT? OBD?
