What top speeds (GPS Verified) have you gotten with stock gearing? What about with different gear ratios?
Top Speed?

I am more concerned of the gearing and actual GPS data. Bike is totally unrestricted, top speed limiter removed, Rev limit extended slightly. Looking at a 9/10 or 1 mile setup.

gearing wont increase top speed, it's not a matter of gearing, it's a matter of horsepower to push the massive wall of air that builds up in front of the bike, to bust that 200mph mark you will need around 250-300hp or so.. there are HP/speed calculators online, you enter gearing and hp so forth then your frontal coefficient in sqft.. the 186 isn't max but darn near, if you can get 195 out of it you're doing good, you won't top 200, there is a wall or barrier around 196ish anything after that the hp required just to go 10mph more is exponential, 165 will get you to 195 or so, if you want 210 you will need about 375hp, and it just keeps getting harder the more speed you want to gain after that then you hit more walls or barriers, at some point you will actually create a sonic boom round 750mph.. speed of sound, you actually create shock waves that are extremely audible, nuts

as an example, the quickest quarter mile run by a vehicle is 400 and change in 3.58 or so, or is it .23? forget, anywho this is a turbine powered set up, 23,000hp so its odd you can do oh 200 in the Q with like 750hp, but to double that speed you need 23,000, turbine..
top fuel are in the low 4's high 3's and have around 12,000 hp 375-390, for that additional 10-15 mph it requires another 8000hp..
of course if you let them go to a 5-10 mile mark of course they will go faster but not what one would expect, I don't think 23,000hp gets them to the speed of sound or even close, 450-475 maybe?
there is a vehicle hit speed of sound, only one, thrust SSC, went just over SOS round 763 mph or so, jet turbine power, just over 102,000 hp.. so you get an idea how exponential the hp required is after that first barrier that really begins to push back to achieve more speed in atmosphere.. gearing won't help at all

The factory gearing, with the standard tire, will get the top speed out of your bike. Even one tooth larger on the rear sprocket will be too high for standard (unrestricted) HP. One tooth on the front sprocket is way too much, so if you want to experiment, go one or two on the rear. As Twisted said Horse Power is the only way to go faster.

Ok, so here is the real deal on 1 mile top speeds.
To hit an actual 200mph in a stand start 1 mile run it takes anywhere from 190-200rwhp. I have heard rumors of it being done with a super lightweight jockey with only 185rwhp, but I would take that with a grain of salt.
As for gearing, there used to be a gearing/top speed calculator online, but I forget where it was.

I do use gearingcommander.com, but it does not seem correct as I have exceeded what the chart shows, based on multiple GPS apps that all showed the same data.

That site has always been pretty damn accurate, but if you are comparing multiple GPS data that is all reading the same, I don't know what to say. We had a few guys here that were big into the 9/10 racing scene, and they proved a lot of people wrong when they went 200mph with only 185rwhp. Until then it was pretty commonly believed that you needed well in excess of 200rwhp to go an actual 200mph.
What is gearingcommander saying, and what are you seeing?

I know this is a old post but I would like to share My experience with my 2003 Suzuki gsxr1000 Canadian orange and black. Lowered, stretched, yoshimira, power commander, cammed, No limiter. (My knowledge of the build). 6a.m. in September 2014 I achieved a top speed recording on my Garmin GPS of 203.4mph. I had the bike wind all the way out till it seemed as if it was cutting out at 15500 rpm or so was hard to see. I only had a view of about a inch above glass and couldn't move my head cause the wind. I would let off a smidge and get back in it and same over and over for 3 miles roughly. Reached top speed in less or more than half mile, maybe even a mile happened fast. So yes 203mph is achieved. 🤙 Also don't recommend it to be attempted cause the wind was beating my helmet so hard I felt like my head was being pulled from my shoulders. Bike was sturdy and comfortable feeling but I was lucky honestly. Anything could happen.

I’ve seen the first video on YT. The guy did 187mph GPS with mirrors. By removing them, he would easily do 190mph GPS.
After countless tries, gearing, areo, I have achieved 207 mph on a pure stock motor. Recorded by TWO gps measuring devices both matching each others speeds. Dragy and GoPro telemetry. I have the video is u want me to post it.

stock motor what? you need around 200hp or a real good wind at your back, it's already been proven over and over
Ok. Well I have a year of data. Showing every modification, all the aerodynamics, all the gearing changes. Hundreds of videos. All topping 200mph GPS using dragy and GoPro combined on same run. Once I got to 200. Then progressed to 202. 206. And then 207. Took 11,000 feet to get to 207. But I got there. And I repeat. ALL on STOCK motor. Proven many many times. U want to see the progress and data. U can follow my tiktok USABLIXXER. If u still don’t believe me.
And all weather related data was with any wind under +/- 3 mph in and direction. No run. Humidity all recorded. DA recorded.

I am interested in the final drive gearing changes and outcomes. Searched through the tick tock vids and could not find this.
The loose chain on one vid, is thoroughly frightening ! You got away with that one. Chain off at 200 would be a fun ride. Or passenger ride.

I can tell you the golden magic gearing and tire size. But I’ll message you if I can find out how to do that. Basically all the 9/10ths racers end here. Anything higher lose top speed. Anything lower bike won’t pull it. Lose top speed.I am interested in the final drive gearing changes and outcomes. Searched through the tick tock vids and could not find this.

The 207 was pulled on stock motor with that formula
210? 375hp. I have proven 207 with 186-191hp. And after this motor gets built pure N/A. With an extra 20-30hp. U will see 215-220
