I hoppe they didn't ship the whole thing back to Japan for that.
"they found a "possible surging of the intake valve spring when the unit is operated under unique riding conditions, such as on a racetrack. "
Revs faster than the springs can recoil???
I'd still be sitting on mine until I heard more about what the fix does. Hope it is true that performance is not impeded.

Get a copy of FastBikes, first full test of the new 10R and it appears, at least the Euro version, is going to be a challenger for the BMW.
I want one but may have to wait a bit.

I still have to go back to my thought on the other thread we had going. Why didn't this problem get discovered in testing? That was done on a racetrack, I think, wasn't it? I smell a rat here. They're not telling the whole story---or any of the real story. I'd wait at least a year before buying one. Who knows, in the meantime, maybe Zuk will come up with something to top them all.
At this point, I don't think the battle wil ever end. There never come an end to technology advancing as long as there is profit to be had. There is no such thing as "about as good as it's going to get." Remember, we were using that phrase back in early '08.

went into my local kaw dealer,they have ordered race ECU's to make the 10 euro spec,now when you get a less restrictive muffler will a PC be necessary for the street rider.I guess not as the headers are so well designed.Rook, I remember in 73 when the Z1 came out people saying they wont make them any faster it stops now,that was the end of the muscle car era so it seemed probable

I knew they were going to do that. I wonder what it costs extra?
My feeling is.. YES-- change exhaust and a PC will still be good for a few more hp at least--the stock map is probably not even close if the stock exhaust is street legal here in the US or anywhere else.

Always wonder why our bikes have to be more restricted, to meet the EURO noise and emissions standards, than the Euros bikes do.

From what I'm hearing, the 2011 ZX-10R is shaping up to be the liter bike to beat...in European trim at least. Don't know about the U.S. version though. This is KMC's Magnum Opus, they've poured everything they've learned from years of MotoGP and Superbike racing into the new 10R, if this one's not a winner out of the gate then they've blown it cause it will be a long time coming before they release a totally new machine like this.
Looks like the new 10R easily handles a big bore Hayabusa here:

It's not a design problem that would have shown up in testing it's a vendor issue. Only the bikes that had springs from a certain vendor are affected, problem is, KMC had to figure out which bikes had the defective springs. Most likely bad heat treatment or shotpeening is the root cause.

Was one guy fat and the other skinny? Did they trade bikes? ....and like the infamous nighttime busa v Bimmer 1000rr, we can't actually see WHAT kind of bikes these are. I'm still waiting for the guys at bikeleand to drop their big bores for a literbike. Yeah, they're close enough for most of us but for serious drag racers and LSRers, a big bore is still the one. When they get beat by literbikes, that will be the end of big bores------or they will get bigger. That's what they're waiting for--no more competition between the busa and the 14-----they want to get consistently beat on their own turf by a literbike before they do a design revamp.

rider on that literbike looks pretty small.
Looks like he was an "average" sized guy...
(from 10r.net)
Unfortunately Garth's bike was hitting the speed limiter before the 6/10, and the bike was geared 1 tooth down from stock in the rear. I was really bummed that the bike was hitting the speed limiter. I had a fun time riding the bike and as always it was good to see some old friends (I don't make it out too often any more). It hauls ass for a stock motored bike! The bike should be capable of 9.10-9.20 with someone my weight (180 without gear).
The 2011 10r was geared for 6/10th's of a mile. All the bikes he raced that day, including that Busa, were geared for for 9/10th's, but still ran the 2011's race (6/10th's). Also, the 2011 was runnin' race gas. Not tryin' to take anything away from the new Ninja, just pointing out that there's always two sides to every story. Garth is apparently having trouble getting around the TSL on the 2011, which is why the bike is currently geared for 6/10th's.
So Kruz, when you gettin' one? I'm gonna wait a couple of years, but w/o a doubt will be putting one of these in my garage.

0:27.......looks like a thin guy in a grey t shirt on the 1000. Busa rider looks geared up but hard to tell. Another 17 lbs at least with gear on.
If that is Garth on the 1000, he's apparently ~180 lbs without gear according to his inet posts..
The new ZX-10 might be a very capable bike. Top speed isn't probably what i would like to do best on it anyway.

The guy on the 2011 is 180lbs w/o gear. It's not Garth. I quoted that post from the rider.

I'm considering it Dogo but running out of room in my garage right now. I think I will wait until a few of the bikes get out there and we see how really good they are and also if there are any more problems. Also, prices may start to come down a bit as the market gets saturated. If a bike is good it'll be good for a long time, no need to be the first kid on the block to rush in and pay full pop.
The literbike shootouts will tell the tale, can't wait!
