Launching

I have a 03600RR and was wondering what rpm most people launch at. I know the answer is probably "as high as you can with out looping it", but is there a certain rpm where you wheelie a little but still launch hard enough to get a good 60ft? Thanks

it's all in how you ride the clutch. RPM's up high. Clutch out but only to a point. You don't just dump the clutch. If this is your street bike don't ride the clutch real hard. A stock clutch won't handle it.

Alright, thanks. When you say high does that mean 8k or what?
Thanks

You could consider a two-stage rev limiter. Dyna makes an easy one to install. This has two benefits. 1. you can set the take off rpms which makes your launch more consistent and not have to do sound for where your throttle needs to be positioned. 2. by not "holding it" at a certain rpm, you can concentrate on the delay of the timer bulbs on the tree. 3. The second setting of the limiter controls the over rev which you want to stay away from as the bike will lose horsepower band and possibly a mis-shift.

With my 600 I would leave a about 7,000 RPM's and as I let the clucth go slowly i would roll on the throttle. as long as you don't drop the clucth the front wheel should not come up to bad. Tip keep your weight on the front of the bike that will help alot.

Hope this is of help!

I go around 10 grand. But my bike is lowered 4 inches in the rear and 2 in the front then I strap the front and I have a 10 inch over swing arm. That front end just stays down even on the bottle.

Thanks for all the help guys. I might look into the limiter you were talking about. How long will a stock clutch hold up under these types of launches? Thanks

Stock clutch = not long if you are slipping it hard. Take it easy out of the lights and it will last a long time. I have a MPS full lock up clutch. Works great but takes awhile to get use to on the street.

thekid_600rr -> RE: Launching (9/3/2006 10:46:54 AM)

I dont hold it at one rpm i rev it between to mid and high and feather the clutch out. I meen it works for me i have only been the the 1/8 mile but i ran a 6.98 so that shows something. Just do what works with your style and have fun..

06rr600211 -> RE: Launching (10/11/2006 11:31:22 PM)

i got a 06 600 and i leave at 12 5 all the time. its all about slipin the clutch . i mean some ppl say that the stock clutch wount handel but iv been on my stock one since march and all i ever realy go though is 1st fiber. but it dose help if u got the bike lowerd and straped that will help . and if u plane on keepin the bike for a long time then u can get a longer arm if u want that will help to.

thekid_600rr -> RE: Launching (10/28/2006 8:54:44 PM)

i have a 056rr and i kinda launch between 4-7000 rpms. and feather the clutch threw first and jam it hard in second and third it works really good for me. but i guess you have to just run as many time as you need to get it down with your own bike.. ken

Just to add to all of what's been said (I hope).

The basic way to go fast is to get the most horsepower to the ground as you possibly can without doing a massive wheelie.

First you need the most horsepower being created by the engine - that's why people say rev the engine to such and such an RPM. It's true you want more revs, but to maintain your revs your throttle hand must move. As you add load to the engine you will need to give more throttle to maintain those high rpms. Don't let the power drop as that will only slow you down.

To get the power to the ground you have to feather the clutch. Think of it as a tap, the more you open it the more you allow down to the road. Don't let the clutch out too quickly - you will either loose horsepower or lift a wheelie. Neither help you go fast. Don't let it out too slow or you'll sit there going nowhere - a safer but none-the-less ineffective racing strategy.

Next - the more you put to the road, the more you load you engine. Keep giving it more and more throttle to keep the horsepower up DESPITE the added load to the engine.

Once you've got the clutch full out and the throttle full on it's going to be milliseconds before you need to shift to 2nd.

After the shift to second, perfect the tuck, and run her out through each gear.

i could really launch hard wherever, but to be perfectly honest its really not good for the bike and if your bike has balls it has balls and a 5k launch is sufficiant if all the power is getting to the ground. i know with my stretch bike if i launched it at above 6k the tire would light up and not stop, though if i was using a pilot power or shinko drag tires that would probabaly stop LOL.
