Took the 1290 to the Drag Strip

Postby big_sur » Thu Aug 07, 2014 4:05 pm

I figured I should probably go to the drag strip at least once in my life and having a new 1290 is probably reason enough to try it out so I went out the Bandimere (Colorado, elevation 5,800') tonight and ran it down the quarter mile a few times. Best was 11.139@130mph. I didn't think that was too bad considering it was my first time going and the mags only got 10.93 out of it.

Yeah, I tried it once without and almost looped the damn thing. I threw the slip away from that run, but I think it was a 12 something

Excellent! A few mags, just recently, have gotten 10.2 and 10.3 runs. Don't know if they left TC on or not and I presume KTM gives them a broken-in bike. My 1290 is the hardest accelerating and quickest bike I've ever owned.....up to about 125mph. Then rpm and aerodynamics and the realities of owning a torquey v-twin allows my other inline 4 more aero bikes to catch up. More like "scream by". How often do I ride over 125 (which is what the end of the 1/4 mile replicates)? Rarely. I'm more of a 0 to 100 guy. In these parts doing 35 over posted limit is enough cause for police to take me to jail as if I didn't need more reason not to ride at those speeds on public streets.

Your 130mph trap makes me smile! My aforementioned inline fours are topping my 1290 by about 5 to 8 mph.

On a somewhat related note, the Diavel is posting quicker ET in this video (with a lightweight pro at controls) than the mags initially posted: http://www.cycleworld.com/2014/08/07/sm ... drag-race/

Pretty consistant times there.
I took my 990 down last year and managed best ET of 11.4 so would expect better than that out of the 1290.
Found reaction time was the biggest factor in achieving a good ET.
Will find out this summer.

What elevation you at?
Maybe you're a much better drag strip launcher than the OP or you're a lot more comfortable on your 990 than he on the 1290.
Plus the fact remains that the 990 is a quick awesome bike. Most mags (gosh I detest even writing those two words) were getting high 10s from the 990 at sea level with good riders.

Beyond the elevation (17% power loss @5,800'), I think my 60' times should be closer to 1.6, which if you go by the rough rule of every 1/10 at 60 is 2/10ths off the ET, that would put it around 10.3ish with a good drag racer. I imagine that kind of 60' time would be difficult to achieve on this bike though given the amount of torque and the geometry. There's a lot of traction on a drag strip, much more than the street or a road course, so it's difficult to keep the front end down while still accelerating quickly.

I imagine the consistency in times between what I ran across several runs and what the mags I read ran, involved leaving the traction control on. I bet you could run faster if you turned it off and really know what you're doing (and don't care all that much about burning up your clutch).

My understanding is that the reaction time actually has nothing to do with the ET, the clock for ET starts when you move, not when the light goes, so you could technically still run a 11.1 with a 12 second reaction time. The reaction time only comes into play when you're racing someone, as you could actually win a race with a slower ET if you significantly beat the other person's reaction time. As it was explained to me, to win racing, you need the lesser of the ET and the reaction time.

Track here is jsut above sea level so probably counts for a bit.
The two times I have been down the strip reaction time definitely counted, clock starts when green light goes on.
Biggest issue I had with the 990 was keeping the front wheel down, got quicker when I learnt to keep an eye on the tacho and change before hitting the limiter.

Made the list...who'd have thought you'd ever see a KTM on there

What rpm did you launch at with TC on?

Did you sit further back with the "band-aid" tc helping front end loft?

First gear start I presume.

How did the bike react, with TC, with such a violent launch at whatever rpm?

Don't need any in-depth research at a drag strip to work that out....just go outside and find out in your driveway :)
I reckon it is easier on the bike launching with the 16T sprocket.
1st gear runs out a bit quick, but it is made up for by reducing that stumble low down.
Airbox, exhaust, PCV, quick shifter and 16T will get you into low - mid 9's.

I remember in one of the first videos of the bike the journo found that he got a better 0-100mph time by starting in second and abusing the clutch. Wonder how much difference that would make at the drag strip?

Didn't really notice, but I would guess 4-5k range

Up on the tank like a dirt bike. The TC is definitely handling the throttle once the clutch is out out though, especially in the first few gears.

First gear start I presume.
Yup

I wasn't dumping the clutch and expecting it to figure it out, as you can see with the 60' times. It was more of an aggressive feather. The more aggressively you let it out, the more it wheelies and the more the TC has to cut the power, so with the TC on, there's no real advantage to launching hard. It's like there's a set limit and how quickly you let the clutch out only determines how high you pop the front end up and how hard the TC will cut power on you. I think that's why my runs were so consistent despite my complete lack of experience and why I was also getting roughly the same times as those early mag reviews. The TC makes it easy to run a respectable time consistently, but there's kind of a limit on what you can accomplish with it on

Dunno if that wobbly wheel will get through scrutineering at the drags.....

I remember my old 1050 Speed Triple being the easiest bike to launch off the line. I would shame litre sports bikes,and be off like a scalded cat, albeit for the first 50 yards :D
A heavy fly wheel helped to make this possible.

Excellent description of RT and ET.....that's why it's better to work on your staging and launch during time trials than to try and get low reaction times during that period. Then in eliminations you can add in your average (guess) reaction time to your dialing and have a better chance of beating the other competitor.

My 990 SD will run 11.10 @ 126 mph on a decent, good launch run and reaction times are usually .165 to a best of .003 so I factor a .200 into the dial in time. Last time I went to the local NHRA track was last year......went 5-times, made the final three pairs three times, got runner up once and top eliminator once. Fun time, and all the other bikers all talk to each other in the staging lane..........not like the cage guys :mrgreen: DAMHIK

The double row of bikes stretched around the corner back there :shock: That TALL(est) Orange and Black bike there is my 990, even with the fork tubes slid up until they hit the underside of the handlebars and the rear dropped it's still the tippy-toe tallest bike in the field for some reason? :lol:

Sometimes it's not good to heat up the rear tyre especially without TC :oops:

Good fun and good times...pun :wink:
