What top speeds (GPS Verified) have you gotten with stock gearing? What about with different gear ratios?
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.What top speeds (GPS Verified) have you gotten with stock gearing? What about with different gear ratios?
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.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.
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.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.
I’ve seen the first video on YT. The guy did 187mph GPS with mirrors. By removing them, he would easily do 190mph GPS.2017 GSXR1000 TRUE TOP SPEED
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.What top speeds (GPS Verified) have you gotten with stock gearing? What about with different gear ratios?
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.stock motor what? you need around 200hp or a real good wind at your back, it's already been proven over and over
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 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.
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 215-220gearing 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
