Yamaha fixed the ECU. The bike is fully capable of revving to 17,500, Yamaha just decided against doing so for purposes of engine life.

This really isn't anything new, all redlines work that way. Nearly all bikes are capable of spinning well past their redlines, but the manufacturers limit how high the engine can rev to improve durability.

I was coming out of my clinic,going to get on my v-65 sabre,when I saw a new r-6[anniversary yellow]sitting there .Brand new,just the paper plates on it,less than a week old.So I wait around, and about 20 minutes later,the "squid" comes out all decked out in the latest fashion leathers,etc.So we got to talking and I asked him "How long have you been riding?" He replies"Oh I just got my license three weeks ago"Holding back my laughter,Iasked him if I could take it for a ride.Being,black,I guess he thought I was going to hold him up,but I gave him the keys to my sabre and off I went.Came back 15 minutes later ,handed him the keys,and told him to enjoy his ride.My impression? Don,t matter if it tachs out at 10,000,12,000,20,000,50,000.The thing is scarey fast,way too fast for me without some months riding it around SLOWLY.Glad I gave up emergency room work,I would expect to see him soon.

I see where most MOs don't much care and they are right if you are riding on the street. But this is about honesty in advertising. The whole marketing game is the race bike experience and performance. There is also the whole technology one-upsmanship thing going on too. Personally I hate the way they fabricate the weights of the bikes.



Again, be suspicious if the average piston speed goes much over 4,000 ft/min. Yamaha is claiming 4,850 ft/min for their R6 with a 42mm stroke and 17,500rpm redline. Sure! I believe that motor can do it, but so could the Triumph 500 GP bikes in the '60s - for one race.

max power remains 14,500 rpm, so really it is just overrev, good on the track to save a shift here and there and a few tenths of seconds, which all add up...

u guys realize advertising and stuff all happens months before actual bikes appear in the U.S. Obviously, the bike can spin higher but a decision was made somewhere later on not to allow it to. Wonder how high FX R6's are spinning? Hmmmm...

i thought the motorcycledaily guy wrote an excellent R6 review, apprently an old Willow springs hand riding a track he knows well—and a good writer to boot. For me, it is all about an entertaining read, since every 600 out there can win races on any given day given an almost infinite list of variables.

also a little Triumph 675 deal up there this morning from Norway or someplace not so hot...

That story seems to be a big crock. The engineers don't design a bike, build it, and then decide to check the rev-limit by cranking it over and watching the tach.



"Ahhhh, loook, Akira-san, bike rev to sehvunteen-five! Tachometer say so. We make-uh gooood job!



What a bunch of nonsense.



The Remus version sounds way more plausible. If that is indeed the truth, Yamaha probably just niggled with the tach calibration to get the needle to point past 17K. And you're right, they should have just admitted it, but they must have feared it would kill the bike before it was even launched after so much hype.



Well, they're at least doing the right thing now. I doubt many people will be returning them.

Re: Wow...

Were you talking to me? I think perhaps you need to get out and Ride more. I was musing on the strange (or maybe, NOT so strange) turn the conversation was taking. I haven't the faintest idea *WHAT* you're going on about.
