Well, I still prefer my Limited Edition 03 R1 and think it's the best model, but the 09 isn't that bad. I'd ride it...

So...

Have anyone figure out what the new firing sequence does for the inline-4?

[will smith voice]oh hell yes...!!![/will smith voice] LOL

in short, it's an I4 masquerading as a 90 degree V4. think the racier 1000cc VFR that honda has failed to give us in spite of their LONG history with multis. the only thing yamaha did was cut a V8 LENGTHWISE down the crank (what is a V8 'cept two banks of inline fours?). and instead of machining a 180 degree crank? they asked, what if we RETAIN the basic V8 crank's configuration, but just shorten it? this affords a serious packaging, cost of manufacture, and weight benefit over building a traditional 90 degree V4.

to appreciate how this is nothing short of GENIUS thinking, one has to understand how heretofore we have only thought to cut V8's in half PERPINDICULAR to the crank (ie. V4's) so props goes to yamaha. the rear wheel cares not and knows not how the pistons or throws are arranged around the crank. on paper, the resultant firing order for 720 degrees of rotation (2 spins for a 4-stroke cycle) is the SAME as a VFR. also, by shortening the stroke even further from what the last generation R1 (already shorter than everybody else) used gives them a tuning variable for managing torque input to the crank (and thus traction). this, better than what switching to having a piston fire every 90 degrees would really allow in practice. more kudos to yamaha. the other benefit of a short stroke...? simultaneously good top end. omg, that's having your cake and eating it too.

for example, if they were to use the "daddy long stroke" of say the '01-'08 generation gsxr1000...? it would be difficult (albeit not impossible) to make this work. what THAT would be is a highside machine from hell. while all the rest they claim is true, their claims of "uneven firing order" is marketing hype. it's a misnomer. on the contrary, it's VERY even. when you're putting a piston at TDC every 90 degrees... and firing it... in my book, it can't be anything BUT even. this label of "uneven" can only be truly claimed by the D16 and the new RSV4. as you see i've maybe thought about this a lil' bit. LOL

deep down, the motorcycle industry has a problem we dont talk about at parties...

Just ran across some Endurance images of the R1. Looks tasty. Is the covering over the lights to protect the lenses or amplify the output? Hmmm....

If Yamaha released the R1 with those bulging'er eyes people would still complain. It looks like you are choking a frog. Still...I dig the new bike now. I've yet to see one on the streets though.

I've heard Yamaha has been doing well in BSB...I'm pulling the BSB races down currently and will hope to watch them over Friday/Saturday while I'm on a trip for work.

well the idea is to take styling cues from how the race upper has been designed. observe how they made a nice smooth contour in place of the head lights. okay, what if that smooth contour were a clear lens with an angel eyed projector behind it...? why that would be exactly like the old R1 headlights that everybody loved (only shortened). how yamaha missed that and instead green-lighted the buell firebolt look is beyond me...?

what you really mean is you have yet to HEAR one on the streets. no they are not much to look at, but some guy at miller (no not spies) was using one to scoot around in the back paddock during the weekend. he had nothing more than a set of "2 mothers" (ie. 2bros.) slip on's. sweet jeebus did that sound tits as it echo'd off the buildings and garages.
