Anyone want to guess what the top speed of the 2015 1199R and the 1299 will be?

I think Ducati underestimated the strength of the spring required. I witnessed firsthand the valve closing while my bike was on the dyno. We couldn't figure out why the bike was cutting out around 10k rpm, and then finally, while it was running, we watched the valve. sure enough, as it got close to 10k, it started to turn by itself.

we safety wired it open, and for extra measure, spot welded it. It won't close now :)

If this is not an individual case, there seems to be a design error in the valve/spring design of the 1299 OEM exhaust, regardless if the servo/cable is still there or not (as stated correctly somewhere, the opening force is only generated by the spring, not by the cable).

Never heard of similar probs with the 1199 OEM exhaust....

I'm Glad that my 1299S, due to full Akra-System, has no flapper valve anymore :)

The 1299 in stock condition goes 304,4 Km/h - measured with GPS
Thats the the point where it runs to the revlimiter with stock sprockets
 
In August, I did a Nate Kern two day event at Roebling Road. I had the OEM bodywork and windscreen on my 1299S. I have the exact same gearing as OEM, but I converted to a 520 drive. Roebling Road has a decent length front straight and the bike was set to race mode. The bike was "still" pulling going in to the brake markers from the front straight in to Turn 1. Back in the pits, I checked the top speed, which I assume was being tracked via GPS, and it consistently showed a top speed attained of 175. I am 6'3" and weigh 215. The freakin' wind buffet was horrendous and I was flattening out as much as possible. So, with OEM screen and bodywork, I got 175. I could swear the bike was still pulling so I'll see what it does at places like VIR and Road Atlanta which have longer straights (which also make you believe in Jesus when you're pegged in 6th gear with aggressive company on all sides wanting to beat you to the next turn).
 
I was at the airfield yesterday doing standing mile. Small headwind, but bike was on the limiter well before mile. Hit 287km/h which is 178,3mph according official timing. I don't think it would do any more than 290 even with tailwind.

And yes, speedo was showing 299km/h and three lines already around 1300m mark. Just looked DDA, it was saying 310km/h. So speedo is lying 23kmh in a speed around 300.

And here is a video from it.

You won't go faster at Road Atlanta. The straight seems longer, but you have that bend (T9) in there, and you enter it coming out of T7 which is only about a 30-35mph corner. As opposed to Roebling's straight where you enter it already carrying 120mph.

At track days you hear people saying .... like "dude, I was hitting like 190mph going into T10" and all kinds of .... like that, but none of it is true. Even the top 5 AMA Superbike riders will only hit around a true 178-182mph before braking into T10.

You (read: anybody) won't see speeds any higher than that at Roebling either. I don't know of anyone who has ever gotten over a true 185mph at Roebling, even while setting the lap record.

I hit 126 at Roebling Road.....in 1981.....on a 750F Honda. :D. BTW, for some reason Daytona was the fastest track for a bike already maxed out. Something about the banking.....in 1982....on a 750F......:D

My responses are limited, you have to ask the right questions.
 
Owners manual clearly states that the speedo overreads 5%.

Where were you running? The Texas Mile has pavement all the way back to the starting line... Having to ride back on that rough gravel and rocks must really suck..

Typically factory speedo's are waay off at that speed..
When I first ran the Texan Mile back in 2007 on a 2007 ZX14 the first time I ran the speedo showed 191.00 mph...I got ll excited until I got the time slip LOL When I finished the run the Krondex clocks set up on the track showed 174.265 mph (actual speed) :)
