Wild 127HP Yamaha MT09 Woolich Race Tools Quickshifter Auto-Blip Launch Control Pit Speed FLAMES!! 

Its not. Look at legend cars. They get around 130hp out of these engines

It basically causes more back pressure 1 because its effectively a kink in the hose, and 2 because it gives the effect of having a longer pipe without taking up as much room, best set up from what I can tell, aki do a loop, ebay special do, and lextek from what I can find

Depends on kits you choose. Oem quickshifters only do quick shift. Keep that in mind.

Akrapovic full system

It's in the title of the video :P

Just the usuall mods plus grants magic dyno tuning :)

Every Dyno reads differently and most can be manipulated to indicate +/- HP... Don't focus so much on the peak HP number, rather the before/after gains throughout the power curve etc

The 2021 mt09 has 118 hp stock

@@zanbocko4301 Rated at the crankshaft, yes. 103-106 hp at the wheel, with 11-12% typical loss.

my stock 2015 MT09 with only an akrapovich titanium exhaust made 114HP. this was due to the speed limiter coming in at 220-225kph right before 5th gear powerband. so the power run had to be done in 4th gear. after a tune, and removal of the speed limiter, it went up to 124HP. there where also some slight modifications to the airbox to allow for greater airflow, this including modifying the snorkle, and changing stock filter for a K&N filter. this was done on a professional dyno where they tune proper race bikes that compete in high classes of moto racing. so this 127HP power run is ''believable'' but they must have done some other mods, or this exhaust is just really good (which is highly likely)

@@wildwilco Or the dyno is just very different from other dynos. There's a dozen contributing factors that determine a number, but the best way to do is is run a stock number on a given day and then run the modified number preferably on the same day (atmospheric conditions and all that). Yamaha continues to severely restrict throttle maps in the ECU. You twist the grip to the stop, the computer controls the throttle at the throttlebody and will not be applying 100% throttle except for a few thousand RPM in a higher gear, before shutting back down severely, unless you flash the ECU.

@@exothermal.sprocket that's exactly what happend. Stock with only a modified exhaust it had 114 wheel HP, and with the flashed ECU, tuned bike it had 124 wheel HP. These are verified numbers from a professional tuner who Tunes are racing bikes for a living. On the same day, with identical conditions.

Yes its a fucking dyno lol

@@ItsThatMilkshake some dynos measure crank horsepower, others measure wheel. I would be surprised if mt09 has 127hp at the wheel since it has 115hp at the crank as stock. So 100-105hp at the wheel without mods. And exhaust doesnt give over 20% performance boost. more like couple horsepower.

@@megapet777 lmao the fact that you watched the video and then asked if its whp tells me you know nothing about bikes or tuning 💀

@@nathangreen6286 lmao so which one is it then smartass?

@@megapet777most likely just a forgiving dyno
