Ok some of you have had them long enough, put a few mile on them changed the oil and smoked them over real close. Now it's time to turn it loose we need top speed from a dead stop and roll-on top speed (from say 60 or 70) I can't wait any longer and mine is still a couple weeks a away. Don't get hurt or get a ticket but please let the rest of us in waiting know.

Hmmmm...............138mph?

i'm thinking 137mph

I think a better question than top speed at this point is....Actual Speed. Therefore someone with a radar gun or GPS that could take "actual" speed compared to what the speedo is stating. At 65 is it off + or - 2mph what about at top end?

Another question Do you feel as though Top end can be reached in 4th gear how about 3rd? Meaning 5th is really a cruising gear?!

Cycle World (Dec 2008) has a great write-up concerning the  . There are write-ups from Jay Gleason, Don Canet (CW Road Test Editor), David Edwards (CW VP/Editor-in-Chief), Paul Dean (CW VP/Senior Editor)and Mark Hoyer (CW Executive Editor). There are also quotes from Dale Walker.

It was written that Dale Walkers top speed and CW's seperately measured speed were both the same at 138mph, which is at the electronic limiter.

It also stated that a 9000 rpm soft limiter steps in at the top of fourth gear, fifth gear is always limited to 8000 rpm and measured top speed was lower in top gear than in the fourth.

Listed under the  specs was Speedometer Error. It stated: 30 mph indicated was actually 28 mph and 60 mph indicated was actually 56 mph.

Hope this helps.

I read on one of these threads one of the guys on media day saw 144, 145 on the speedo and even if it is off a little 1 to 2% all this is digital so gear position, rmp and speedometer shouldn't allow a 144, 145 on the speedo. Also I read somewhere if it detected a from stop to top end it would allow a drag race mode of 144mph. SO I was wondering if any of the new owners had ran their's all out. I can already see the $850 race ECU as soon as it's released.

Well thats kind of a downer. I guess when it comes from (Badnews) it cant be to good, lol just kidding. Any way does anyone else think that that margin of error is to far off even for a digital read out and computers up the yang? Come on. A top speed of what? taken by what of course what the factory speedo is saying or the real world.

Please dont get me wrong, I'm still excited as anyone to get the beast but I think an almost 4% lost could have improved in this day in age. Of course I understand they want to show better numbers, but at what point does a lie start to become what it is? WRONG!!!

Ok thats my first complaint. Pray thats my only one. (fingers crossed). All this waiting is starting to take its toll. I hate nick pickers yet I'm starting to become one.

For some reason Japanese speedometers have always been notoriously "optimistic". Years ago when I was into the Rally scene everyone was running digital bicycle speedometers. Multiple odometers, easily calibrated to compensate for tire size and accurate max and average speed indications.

I think they are probably trying to avoid any liability (?) by having the speedometer read slightly high.... that way when some sue-happy lawyered up idiot tries to sue Yamaha for making the bike "too fast to control" or some other stupid claim, Yamaha can try to distance themselves from it. (God forbid we take personal responsibility in this society, we should expect this kind of treatment).

If the race ECU indeed exists and is released (and gets rid of the top end limiter), I'll be at the dealership ordering one for sure. The fact that anyone on a twatted out raggedy 600 (or better) can and will eventually catch and pass me on the open road is truly unacceptable. With almost every bike over 1000cc's hitting at least 150, I'll never understand the neutering of this bikes top end.... Oh wait a minute, I just re-read my first paragraph.
