Fastest quarter mile 2.5L rocket

Leaving the line in 2nd gear might cut the 0-60 ft time. You have enough torque. I read some even leave the line in 3rd gear.
edit, watching the video looked like your brake light was coming on at times? Is front brake lever coming back? Looked like bracket racing trying to stay ahead and not break out of your time.

its triumph thing, once you turn of TC off, the brake light comes on / off. People keep asking me why you were braking, i keep explaining to everyone, i was not braking lol, its just when you turn off TC, it blinks, not sure why triumph did that, since ABS modulator also controls rear brake light for some reasons, I checked in the electronics circuit diagram.

What gear are you crossing the line in, what's the rpm?

1st gear, started crossing at 4000 rpm then went up to 5000 rpm in between runs

I heard that too, but didnt try it, i think i will try that , so put it in gear2 and how many rpm?

I wasn't aware of that. So whenever TC is off the brake light blinks all the time? How silly. Like you are in distress or some kind of a road hazard??? LOL, nanny Triumph over reacting on that one.

I was thinking of 1/4 mile finish line. Think leaving at higher rpm's would keep power curve up as long as you can control front wheel lift and a good grip from rear tire.

I would be hesitant to try try anything but a first gear launch because it's still not established how robust the clutch and crank are. A second or third gear hard launch will without a doubt create additional stresses to both. Dont know just how far you're willing to go to get to 9.99 but you could always pull up the front forks about an inch in the triple trees. This will create a heavier front end and be more resistant to wheelies allowing you to leave considerably harder. It will drastically change the bikes steering geometry, and wouldn't recommend it for street riding, but if you trailer the bike to the track you won't have to worry about riding it home.

cant I pull up the front forks shocks once I reach the dragstrip, no? Thanks for this idea because I dnt want to strap the front forks and have a risk of fork seal leaks.

I suppose you could pull up the forks at the track if you were to take with you the proper tools. Be aware that you will want to use a torque wrench to tighten triple clamps to final torque spec. I suspect that between an inch and an inch and a half will make the bike a lot less wheelie prone when traction control is off. Do you have the quick shifter option? If so do you have the ability to adjust the kill times? This could wind up saving you close to a half a tenth if they set them up with long times per the factory spec. My guess would be for the factory to error on the side of caution, with long ignition kill times. You may also be able to set up your upshifts by pushing down on the shifter peg. This would make for a more positive upshift and potentially quicker shifting. The thing I would say at this point is that you're getting to the point now where there is becoming major deviations to the way the bike came from the factory. If your gonna go that far why dont you just throw a 30 dry shot of nitrous to the thing and knock of a half a second!!!
