Default Clutching off the line

I'm directing this Q towards the RR and F4i as they are the bikes I'm considering buying.

I had a YZF600r and when you go to launch it'll do fine and normal up to 5.5-6k rpms, where you can ride the clutch and slip as much as you want to get the ideal launch. This was good, but it made so little power below 6k rpm that it would bog. Now take it to 7-8k where power is good and you think you'll get a great launch and now the clutch just stabs, its either in or out, no in between, no slipping.

I never could launch that high because I'm not quick enough to catch it if it began to wheelie. I want a launch I can control instead of revving and dumping the clutch.


My Q:

On the F4i and/or 600RR can I rev the motor all I like and still be able to slip the clutch, thus getting a controlled launch. Do I have to keep the revs low in order to control it like in the YZF600R or must you just rev it high and dump the clutch in order to get a good/quick/powerful launch?

You can rev them up, i launch round around 8k on my f3. But maybe its just rider...i dont really know but, my buddies all launch higher than 6k rpm

Ive got a 09 and at the drag strip if i launch at anything higher that 6500 the front is coming up. No matter how i slip it. Now when i launch at 5500-6500 my front wont come up and it will give me my fastest pass times.

When im on the street i can usally launch over 7k.

I think alot of it has to do with rider skill to be honest.

I get a nice controlled launch at about 8-9K dumping the clutch on my 03' 600RR with a -1/+2 gearing. I'm not real light weight so I can easily keep the front down.

Yes, it is alot to do with rider skill. Thats why I'm asking. I'm not skillful enough to launch by dumping the clutch. Hence the question, can you slip the clutch at all rpms or does it bite at certain times?

If your not skillful enough then dont try it. Start at 3k and work your way up. There are alot of variables (rider skill, weight, surface, temp, tires, and rpm)
