launch techniques?

Use throttle control with your right wrist and you'll be fine.

But I can't seem to go down the track without it flipping over on me

brocks sell a spacer that will disable the slipper clutch, while this wont directly stop the front wheel lifting it will stop the bunnyhopping on the starts and will be a lot easier to get of the line, easy to fit too.
the hp calibration kit wont allow you to keep anti wheelie and turn tc off

Hello, I do races in Europe for years and I have to say the S1000RR launching capabilty is not so good.

With japanese 1000cc bikes, I used to rev at 10K/11K then I droped the clutch in order to have a progressive slip until the grab, I did that in the same time I twist fullthrotle. Once the full grab was Ok and whatever the achieved rev I shifted up the second gear.

With the S1000RR, i tired this but i did not succeed. The stock clutch does not allow it. After many tests, I do that:
I rev at 6K/7K, I drop the clutch in a very aggressive manor while I twist fullthrotle, once the bike is good running, I shift up the second gear. It is close to a very aggressive launch at a trafic light.
This way is almost efficient than the "japanese" one.

I ride in slick mode, dtc on or off depending on the conditions.

Some people have hinted at it but from what I can glean from magazine tests and people actually using the bike maybe this is not something you really want to get good at.

A perfect launch, meaning maximum acceleration is HIGHLY destructive to the clutch. People talk about eating clutchs like tires if you are doing it right. At least that is the impression I got from the Brock's crowd who drag race a lot.

So maybe get some practice on something less expensive or better yet just be a bit slower and have your clutch last a lot longer. Those tests in magazines where they talk about feathering the clutch at 9k+ and floating the front end until the clutch fries don't sound worth it for the real world.

When i launch my bike on the drag i don't use too much revs, maybe becuase i still don't have the balls to do such thing even after participating in more than 10 drag events during last year's season

My bike now is lowered and strapped but still on SWB, i added Brocks clutch mod which really helped to launch the bike better, also the best investment was installing the new Conti SportAttack2 tires, they are simply super sticky tires. I add a -1 front sprocket

I managed to get a personal best time of 9.57 sec with a 1.782 sec 60ft time on yesterday's drag night event.

On my friend's little strached S1000RR with bolts on, i managed a 9.45 sec with a 1.754 sec 60ft.

Just keep in mind that this kit will disable the standard slipper clutch job..

I turn dtc off and go in slick mode....To me the key is to get the back tire to spin so I have taken to adding tire pressure to 35 or 37 psi....I try to launch just like I learned in motocross...lean way forward with your weight mostly off scooter rev up to around 9,000 (Sometimes more) and drop the hammer...the back tire should spin while you shoot off like a screaming banshey, as soon as the back tire starts biting it will start wheeling and then you just modulate the clutch the best you can and stay on the gas the best you can....make sure you stay down and leaning forward the whole time...if you are trying to do it sitting up, well that is wheelie city...also consider tying the front in down with belts, that helps a lot with the wheelie problem. Anyway that is my two cents worth...btw just as a matter of statement I am a former AMA expert license holder back in the day with pretty extensive experience including quite a few trips to the strip with all manner of go fast scooters.

good advice. Those front end straps make a big difference in keeping the front end down....Had some brocks straps on a gsxr 1000. If you slip the clutch right the clutch will wear out quick.

Ditto: I use the Ed Bargy technique. He says, when the green flag drops, just GO! In other words, don't over think the start, but just GO. IF, you are faster than the guy who started before you, you will most likely catch him.

But I'm talking road racing, I think the OP is talking drag. Thus, my advice is useless.
