Is it possible to down gear it enough to bring the front up with power?

Man-throttle.

You can get the front up off of the power on a CBR600F, you just need to use man-throttle. Apparently a good technique is to roll along at walking pace, shut the throttle then immediately open it again, and the front should lift.

However, if you want to downgear, drop a tooth on the front sprocket. This should make it easier, but dont do it so you can wheelie, do it because you want better acceleration. You can wheelie easily enough without it.

I got the front up just cracking open the throttle (did have a pillion though).

With all due respect... why comment on something you have no idea on? Rolling Eyes

I can chuck it up off the clutch but there is nothing there on the power.

Laughing nice. Did that affect top speed much? I take it the front came up when you opened the taps?

I've had some fairly heavy people on the back, the front has got light but not to the extent of being airborne.

Wonder if mine's been up geared. Confused I've had an indicated 160-165 on the clocks.

Funnily enough, Covdude does that a lot, but not in this case. He's perfectly right. You should be able to do on the throttle wheelies on any healthy CBR600F. Unless you don't open the throttle enough...

First off, which CBR600F?

Disclaimer: Try these techniques gradually and sensibly - you don't want to find that your bike is excellent at wheelies too quickly!

Have you tried making sure your weight is back, then opening the throttle to wide open throttle and holding it against the stop until you get to the redline?
A lot of people think they are doing this, but are naturally not - partly due to a fairly 'long' throttle meaning that if you start at idle, your wrist is often at a painful angle at wide open.

On a CBR600F I wouldn't be going for a walking pace to snap the throttle on and off. Something like 6-7k rpm at a guess. Be accelerating, then snap the throttle off, then back on again hard.
This helps bounce the front down, then pull it up.

Finally, why not use the clutch? It's slightly more scary to start with, but gives you more controllable wheelies that are less scary in the long term. Click on my profile for a guide I wrote.

Oh and yes, you could down-gear it so it'll wheelie more easily in first if you wanted.

The front lifted on my Daytona with fast throttle opening in 1st.

You can lift a CB400SF on throttle if you get the revs right.

Clutching up is probably easier, I only used to power on because I couldn't clutch them up. Even then, I powered one on a GSXR1000 with ease... in 2nd... brown pants.

So downgear if you want, but maybe think about learning to clutch it?

To be fair, he does say he can from the clutch.
Just curious why not use that.

I like the part where he thinks downgearing will make him able to wheelie.
