Well, the day was absolutely gorgeous yesterday, and decided to test the Busa's top speeds with and without the TRE. Here's the results:
As we all know, the speedo's indicated speed is faster than the actual speed (GPS). When the speedo indicated 185 mph (buried needle in the 2005 busas), the GPS indicated roughly 168 mph. Of course, I wasn't satisfied with that, so I went to do more extensive testing.
Motorcycle Settings/Mods:
Mostly stock 2005 Red/Black Busa with the Hump on. Mods include ZG Double Bubble Dark Smoke Windscreen, Xenon highbeam, Fairing Grills, Tether Kill Switch, Carbon-look Levers, 'Busa Grips, Suzuki Hayabusa Carbon Fiber Crown/gas cap/tank protector, Marble Mod (PAIR VALVE BLOCK), Yoshimura Carbon Fiber RS3 Bolt-Ons, and Dunlop d208 tires. As you can see, mostly cosmetic mods except for the bolt-ons (which don't really do anything performance wise... just a really sweet, kick-ass sound) and the Marble Mod (blocks the hose that takes air from the airbox to the exhaust for emission control purposes). And I guess the DB screen affects aerodynamics a little bit. I'd also like to add that I have stock gearing (I believe 17t in front, 40t in rear).
Setting Conditions:
Beautiful day. Clear, blue skies, with temps in the high 70's low 80's and a tailwind in my favor (I believe 5-15mph winds from weather.com).
My Gear:
Shoei full-face Helmet (Duh
)
Icon Tarmac v2.0 Gloves
Joe Rocket Ballistic Mesh Jacket
Tight-fitting Jeans (minimal flapping)
Boots
For the first runs, I removed the smart TRE (So the bike was "restricted") and had a slight tail wind in my favor.
I accelerated all the way to EXACTLY 10,500 RPMs in 6th gear, where I could feel the bike being limited (I felt the power kicking in, then going a way, then comming back, then going away. I held the throttle open for a pretty long time --- it was pretty obvious that the bike was not going to let me get past 10,500 rpms). And behold, the GPS indicated Max Speed: 182mph
So, WITHOUT TRE:
10,500rpms - 182mph GPS
I did a couple of runs like this, and in both runs the bike topped out at 10,500rpms - 182mph
Then I pulled over, popped the tank up, and installed Ivan's Smart TRE and did a few more runs.
I started accelerating hard from the start. Shifting at redline in 2nd, 3rd, 4th, and 5th, then I hit 10,800rpms in 6th and the bike stopped accelerating. This time it didn't feel like at 10,500 with the TRE. I felt like I had gotten to a plateau. Steady power (not the in and out like before). I held the throttle wide open for a really long time looking down at the RPMs for about 2-3 seconds at a time only to see that the needle wasn't going anywhere --- 10,800. I did this a few times... I looked down at the GPS, and it showed 188 mph.
So, WITH Ivan's Smart TRE:
10,800rpms - 188mph GPS
I did a few more runs like this, and in all of the runs the bike topped out at 10,800rpms - 188mph
Now, here's what I'm wondering... A stock busa doing 200mph? Unlikely. At least not with stock gearing... unless you can Rev the bike way past the redline, which I highly doubt. I also don't think that the bike was limited power-wise because it was pulling at a fairly decent rate until it hit 10,800rpms, then it stopped accelerating pretty sharply. I've topped out other vehicles before, and they are always REALLY struggling near the end... but it wasn't really the case for the busa... at 10,800.. it just stopped accelerating. Another thing that leads me to believe it wasnt lack of power was that the needle was pretty firm... if it was lack of power I'd think that the needle would fluctuate a little bit depending on wind and road conditions... no?
Anyways, these were my observations. Hope you guys enjoy the read and the pics that are to follow. By the way, criticism is very welcom, but please don't post things like "you're a retard for going that fast cause it's dangerous", etc... save it for someone that cares! I value my life a lot and did a lot of research before deciding where to make my runs. Before starting I spent quite a bit of time riding up and down making sure there was no debris on the road, no animals nearby, and no other possible hazards. Also, there was NO TRAFFIC, so if ANYTHING had gone wrong, It would have been me who got hurt. No one else. I believe that people are welcome to do any kind of stupid #### as long as THEY'RE the only ones in danger. If someone's action has the potential of hurting an innocent person nearby, THAT'S where I draw the line!
Have FUN and stay SAFE everyone!

. Nothing I can do about that though...
