Screw the 1299

What do you mean by gearing down. Stock the bike is geared for only 192-194 area


Guys took one of these out to the salt and had it geared up, and it failed miserably.

None of these bikes have hit 192 in 6th, I doubt the dreamo meter on the dash has even read that high.


Mid 180's pegged has been about it. And that is the dreamo meter


Again, to overcome that you better be 140lbs and have your leathers duct taped so there are no creases or flapping leather for aero dynamics. The hump on your leathers back behind your helmet also is a air drag.


Its how the chick did 200 on a liter bike.


Most people think that a bike should be geared to reach the speed desired at redline, but that is not always true. On some bikes peak power is not at the redline. When shooting for a given speed at different top speed courses like Maxton or Texas, the riders use speed calculators (spreadsheets developed for each bike), then pick the gearing to hit that speed at a given rpm. On 1000s and bigger bikes it usually is near redline as it is for nitrous and turbos, but on 600s and 750s peak power is far short of the rev limiter.

A critical part of the 200 mph equation is getting the proper gearing. If a bike is geared "too low" the engine will hit the rev limiter before ever reaching the target speed. On the other hand, if it is geared "too tall" then it may not have enough power to pull all the way to peak power in top gear. In order for a bike to achieve its true top speed the gearing must be such that the combination of aerodynamic and mechanical drag forces are exactly equal to the bike's power at the rear wheel as seen on a dyno.

With stock gearing our 'Busa was into the redline but falling shy of the rev limiter during extended nitrous sprays, indicating that we had the correct gearing, but there was simply too much wind resistance and not enough power to push us that extra 500 rpm. Lower gearing would've pushed it into the limiter, but reduced the top speed.

There are nitpicky people on the internet (I am NOT one of them) that would assert that Leslie Porterfield has in fact never run those speeds on a stock bike (she has, on the Fireblade and S1000RR)...because they are "modified".

no mirrors - "modified"
tape - "modified"

Hell, with those keyboard warriors, taking a manufacturing sticker off the bike makes it "modified" and therefore disqualifies the stock bike speed claim.
 
on a more positive note, don't the WSBK Panigales hit 200+mph on the track? I wonder what Chaz Davies sprocket gearing is, or how different his transmission ratios are to the stock units.
 

yep, that's what I remember. Toseland also cracked the 200mph barrier on a closed circuit with a superbike (322kph = 200mph).

If these guys are hitting 200mph on track straights, needing space for braking, having a full mile does make it easier...although WSBK bikes made some pretty impressive power numbers before the rule change.

I believe the FIM rules are talking about engine internals despite any kangaroo court, or non sanctioned events.


My whole point was to give OP as much help as needed as he has a tough road to hoe here, and without some of these details, he has no chance in hell of hitting 200.


A busa needs love to get there. Getting that 200mph hat is not as easy as thought.


My guess is he will be lucky to get close to an official 190 on pavement, on the salt not even that.

I can tell you from my bike seeing a lot of time over 150 with a full termi and upmap , is it falls on its face after 160 "real speed" at the top of 5th, and the climb through the 170's in 6th is painfully slow requiring a lot of real estate.

But I'm 200lbs with mirrors, and no winglets.


I was looking for that article showing how our bikes are almost the slowest to 180 in that challenge with cars that was posted up last month but couldn't find it.
 
First run was 197.454. Did not get a second run yet. Hopefully this morning I will get another chance before weather rolls in.

197 is awesome.

I've done a few top speed runs, not yet on the pani.

It's mind boggling how the slightest change in body position can dramatically have an impact on drag and top speed.

Keep it up man!
 
This was in rough windy conditions.


You should get it if the wind dies down.

We usually have to wait until first light and hit that morning calm. But anything over 3mph and we cant run.

Little different

So best I got was a 199.29 mph. I only got the one run in the morning yesterday and conditions went down and they called it for the day. This morning I went another 197.0. I went back and raised the forks in the triple trees the most I could ehich was about and inch. I also softened the rear preload all the way and I still had the bike strapped in front. That is when I went 199.29. I pulled the strap slightly more in the front but still had good suspension movement but it was to late. The cross wind I had on the previous run had picked up momentum and started turning into a head wind. They would not let any bikes go until the wind either died down (never happened) or changed direction. Not long after it became a head wind. I said screw it and gave it another shot. I Had everything perfect but crossed the line and knew it was not going to happen. I picked up my slip and it said 195 and I knew my weekend was done. Everyone who was there was amazed at the speed I did on a DUCATI and asked if I had motor work done. I told them what I had and they could not believe it. I told them what it dynoed and they said that is about what I would need to do 200. So needless to say I am not OFFICIALLY in the 200mph club yet. Maybe next year. Also the S1000RR never did more then 192 I heard, so I was happy about that.
 
Great runs. better then I thought. Awesome bud.


What gearing were you running?

And did you have all your high rpm lights lit up on the dash?

This is great - next time I am at Starbux and get asked how fast it will go, I can say "Oh, about 200" :D
