H rated tires over 130 MPH.

H rated tires over 130 MPH.
Has anyone run their H rated tires over 130mph for any length of time? I was thinking some of our European brothers may have had the chance to legally do so on an Autobahn.
I am headed to a race track for a ride day and the front straightaway is easily long enough for the big king to clear 130 (1000cc superbikes get up to 190), and there is a high speed sweeper at the end of the main straight that superbikes take over 130mph, should I be worried about tire failure?
As if I dont have enough to worry about already....

I reckon the blood has rushed to your head, what with being upside down all the time, down under! Not many Harley owners know what life is like over 100mph, let alone as fast as that. More seriously, my understanding is that the 130mph rating for H tyres is for continuous operation, not the brief experience you may have on track. I suspect all the other participants will clear the track as soon as you show up, so you should be safe.....
Yes I've ridden German autobahns, but not that fast - Mrs B on the back wouldn't entertain getting anything like that fast!

Please do not try that with the fork set up uyou have. Let me demonstrate to you.
On a flat road surface with no gravel/debris, roll around 2 mph and turn the handlebars to 45*. Feet wide and be prepared than lock the wheel/brake. Watch the top and bottom triple trees "Tweak" which go out of alignment and twist. Now think about what could happen when entering a wobble. While your tire is very heavy at speed (inertia) but when bad things happen, you have problems.
Why:
Your triple trees are a behind the steering stem design (push) and have a 4* rake. Your bottom triple tree is clamped around the fork tube, your top is not. Your top connection is a bolt that is a slip fit into your top tree. The bolt is tightened and pressure is applied to the top of the fork "nut" (45838-77 BOLT front fork PR/PR-BLK) and the bottom of the fork "bolt" (45419-80 BOLT fork PR/PR-BLK). No clamp and no fork tube captivation to prevent movement. The fork tubes are only 1 5/8" and have a 0.165" wall thickness which deflect at speed. Now what do you think could happen? I get asked by lawyers at least 2X a year when the dreaded rears its uguly head and someone gets killed and they wish testimony. Use your head and only try when you have the odds in your favor. Duck Tape cheap high power LED lights onto your slider by the axle and take your bike out at night.
Reiterate:

I can not or will not try and stop you but I am asking you to please think about what can happen.
Yes Chris did 170 on the salt but his bike was modified.

Reiterate:
- Fork sliders only slide on the captivated bottom bushing on tube and and slide on a sloppy honed Showa slider and not sliding on the steel fork tube like a real fork works.
- Triple trees deflect.
- Infective fork tube connection to the top tree.

Howard, some of us are already converted to your view on fork conversion and Ohlins cartridges. What news on developments?!

Look at your e-Mail and do not say a word. For your eyes only. You will be chosen for testing the first few sets. I want to see if there is any problems with the 30mm cartridges driving with the crown of the road on the right side as well as leaning the bike on the kickstand to the right for those who wish to know. Graham should be entitled to something as we pissed on his tea and than told them where to stick their taxes. Now we pay more taxes!
