14 Tops 200 in England
I spent Sunday and Monday at the UK National Records Meeting which was held at Elvington Airfield in North Yorkshire.
I've just heard that 46 new records were set there, the rider I pit-crewed for was one of them. That's not the reason for this post though.
I didn't take my 14 as it's only done 200 miles but at the event was a guy from Kawasaki UK with a ZZR1400 (ZX-14R). He had made up a new set of slotted rotors with fewer slots for the wheel-speed sensors. He knew about reflashing but wanted to try out his own ideas. It worked.
The course was laid out for flying quarters, flying miles and a flying 1.4 miles. This bike went 197.6 mph in the mile, it was totally stock, just as it would leave a dealer's showroom, including mirrors, registration plate, standard exhaust and not lowered or strapped. At the 1.4 mile mark it went through the speed trap at 203.72 mph.
With a change of gearing from stock and the mirrors off it went 201.16 in the mile and 207.12 mph in 1.4 miles.
I thought I'd share that with you.
(Oh and my friend did a PB of 249.1 mph in one direction and later set a new UK flying-quarter record of 229 mph, an average of two runs in opposite directions - but he was not on a Kawasaki).

A 12-18 mph gusting tailwind was reported:

Do you happen to know the speeds on the return runs?? That will give a good idea of how much was gained from the wind, since tailwinds can be unpredictable.

Haven't got the data with me but my friend on a Turbo Hayabusa was losing at least 20 mph into the wind which was blowing straight down the runway from the West. I think the results will be published on Straightliners.
(Sorry, didn't know Ken had already put this in the dragbike zone. His bike at 233 mph was awesome.)

Important pretty impressed with those numbers from a stock bike! And his idea on the rotors is pretty neat as well.

so the speed restrictions can be removed with modified brake rotors........how about j b weld in the slots as needed.......................

I spoke to the rider about this, remember that the front and rear rotors have a different number of slots, he said if you just fill a few in it throws an error-code. I reckon the pulse-repetition-rate must fall between limits or the ECU will assume either a spin/skid or fault.
Anyway he found that filling some in didn't work and also that the ratio of slot numbers front-to -rear has to remain the same as well.
The parts he made looked just like the originals, minus the black paint, and seemed to do the job. He wouldn't sell me a set, official Kawasaki policy I guess, I didn't manage to count the number of slots in the new parts either but guess about one-third less.
Remember that this puts in a speedo offset and It can't be readily changed back without removing both wheels. An ECU reflash is a better solution but the rotors did work.

As standard 48 slots in the front, 42 slots in the rear (to allow for the difference in rolling radius presumably)
........
Just got the calculator out and the difference in rolling circumference would only make it 43.5 slots in the front so there must be some oher trickery at work in the ecu!
Might just try 2 speedo healers!

Well done to you guys in the UK. For a stock bike very good. What fuel was he using?
Very interesting news about the rotors Bob.
When will we be able to buy these then I wonder. Can it really be that simple since no-one
explored this method that I know of.
Will you be able to keep us informed about the rotors please?

203mph totally stock is unreal.
207mph with just mirrors removed and a gearing changed is unreal.
Imagine what this bike will do with an exhaust, pc, reflash, etc, unleashing it's full c.230hp on a long track? Jeez.
Kawasaki really have blown everything out of the water with this new 14.

The 14R is awesome...but the tailwinds cannot be discounted. My 2007 bike went 211.97 mph with a stock motor (and me at 210 lbs suited), in 1.5 miles, under similar conditions, in 2009.

Fair enough.
But we've been racing top speed events in the UK at both Elvington and Woodbridge for over a decade in all sorts of conditions including perfect tailwinds and no stocker's come close to these speeds.

No doubt the 14R is awesome...we saw 201.76 with just one pass, in more placid conditions, over just one mile (pipe,pc, etc). The 14R is definitely the new king!!!

Flying quarters are with a rolling start, we were doing flying quarters, standing start miles and 1.4 miles. To set any record there must be two consecutive runs in opposite directions within a one-hour time slot. You have to stay out on the runway while doing this and no changes are permitted except refuelling and pumping air tanks etc. The speed given for the record is the average of the two runs which should cancel out any wind assistance. Image below shows how it was laid out.

how fast are they rolling when they cross the start line??

They are stationary at the start line. Can you see the image I posted?
The track is set up to run in both directions because it's a records meeting.
From either end it's a standing start mile, then on to 1.4 miles, then a half-mile braking zone. At about three quarters of a mile there's a quarter-mile section with it's own speed traps for flying quarters. The idea is that it's the same either way and a two-way average is calculated to cancel out the effects of head or tail wind.

BobC,
thanks for the clarification, sorry that i am dense, but i just want to clearly understand what happened. No doubt these numbers will be discussed at length.
