Never mind the rating of the tire ... Those few, precious seconds on full throttle, on the rev limiter in 6th gear ... no issue ...
BUT
C H E C K : T Y R E P R E S S U R E
Go for it - Keep wire tight and rubber side down

You are making a big deal out of it. Just use common sense. Seems you checked most of the stuff.
I would suggest not going straight to the top. Do it incrementally, and the bike will let you know if anything is wrong. I assume you regularly going into triple digits. So, on your next ride notch a little more and get the feel for it. Make sure there is no headshake, or anything funny going on with the bike. Some vibration is OK. Come back home. Check that everything is OK.
On the next ride, take her even further, and so on, and so forth.
You get the pricture - doing it gradually is the key. You have to be lying down on the tank, clenching the bike with you legs, but arms/hands relaxed on the bars.
Be mentally ready for the headshake or something similar, and the key is DO NOTHING ABRUPT when this happens. Lazily close the throttle, and let her slow down naturally before applying brakes.
Make sure all your front end bolts/nuts are tight, especially steering bolts that hold both triples.
If you see a bird about to hit you, put your head down (almost on the tank) momentarily. But don't change anything with the rest of your body and arms/hands.
Also, listen to your instincts. It should feel right at that moment. If it doesn't, don't do it.
Let us know how it feels.

When Z-speed rated tires were first introduced, they were thought to reflect the highest tire speed rating that would ever be required, in excess of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in excess of 149 mph, how far above 149 mph was not identified. That ultimately caused the automotive industry to add W- and Y-speed ratings to identify the tires that meet the needs of new vehicles that have extremely high top-speed capabilities.
W 168 mph 270 km/h Exotic Sports Cars
Y 186 mph 300 km/h Exotic Sports Cars
While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed.
225/50ZR16 in excess of 149 mph, 240 km/h
205/45ZR17 88W 168 mph, 270 km/h
285/35ZR19 99Y 186 mph, 300 km/h
Most recently, when the Y-speed rating indicated in a service description is enclosed in parentheses, such as 285/35ZR19 (99Y), the top speed of the tire has been tested in excess of 186 mph, 300 km/h indicated by the service description as shown below:
285/35ZR19 99Y 186 mph, 300 km/h
285/35ZR19 (99Y) in excess of 186 mph, 300 km/h
for example, the shinko 003 stealth, is a ZR tire, with a W speed rating... 168mph

right....so if I want to go over 168mph...my tires should actually be ZR with a speed rating of "Y" to show me they have been tested that fast.
otherwise I am riding on tires that are rated over 149mph but only tested to 168mph......ZR with a "w"rating.
I hope to some day go over 168 mph
What brand/model tires do some LSR guys run?

good tread, long road with no cross traffic, a buddy and twist.
I rolled off around 175 indicated and it was still pulling. Granted my Laminar lip was wavering under the air pressure but no issues.

...that your on a race track/legal exhibition area?
Yep, I think that is in my top 5,000.

I appreciate the above. I thought I would go 150, 170, 180, 190 + with the intervals being about half an hour in between.
I have this spot that is so flat and straight and it runs for about 4 miles. My wife will be at one end with the two of us being in hands free communication.
I will listen for her to tell me if there is anything strange happening at her end. I'm thinking about September.
Here September is about 75 degrees with no wind or humidity. I need to find a stalk mounted digital recorder.
Yes, and in a system only an engineer would create:

Notice that to be "in excess of" requires the parenthesis.
common, get with it. i've been up above 170 three times sence you started this thread.
it will jiggle your eyeballs
I've been up to 180 plenty of times. But the bike is almost 6 years old now, and I want to hold the throttle open until I reach warp speed or the engine blows, whichever comes first.
