dude, you can't have your cake and eat it too...

If you want alittle quicker, but don't want to lose too much top end, go 2 teeth more on the rear.....wont be a big change, but enough to notice.

but lets be honest you want more low end grunt for those power wheelies dont you ;)

I went one down in the front and noticed a nice increase in midrange power, and haven't noticed anything lost on the top end. Oh, and hell yeah power wheelies are easier now!<img src=icon_smile_big.gif border=0 align=middle>

you wi;ll alway lose alittle top end when lower your front or raise your rear, that's the nature of the thing, but how many of us ride at 150+ miles per hour? Loosing alitle top end will go unnoticed to 99.9% of us....

I heard the going lower in front is harder on the chain, and can make it wear faster. plus, changing the back sprocket to me seems much easier....

granted you will get more grunt from change the front....

to be honest, I know alot of guys who changed their front and haven't had any problems....

my boy has an R1 he went down 1 up front. he said acceleration is quicker. i have over 13000 miles (i ride a little) on the clock, so its time to change chain & sprockets. i'll probally do the work over the winter, but who knows if i get froggy ill knock it out as soon as i get the parts in my hands.

weezy, can you stab it and bring her up in second w/o clutching it?

also did you have to change to a different chain (525 or whatever) i think the stock chain is a 520.

It will not do a 2nd gear power wheelie just by gearing it down 1 tooth in the front. The front end is to heavy. On my friends 99 zx6r race bike, his will do power wheelies in 2nd but he has shark skins and his bike is stripped down for raceing. My bike has more power and is faster than his and mine wont do 2nd power wheelies with the stck fairings on.

The stock gearing on the 2001 ZX-6R is 15 to 40. If you go down one tooth up front, the gearing will be 14 to 40, or 1 to 2.9. Simply put, going down one tooth up front is equivalent to going up 2.9 teeth out back. As you can tell from the numbers, going up two teeth out back is less pronounced than going down one tooth up front, which in turn is slightly less pronounced than going up three teeth out back. On the street, gearing is a personal choice--simply choose the gearing that suits you. On the track, the proper gearing is the one that avoids first and sixth gear, if possible.

It is simpler to go down one tooth up front because the rear wheel does not need to be removed. Also, front sprockets often cost less than rear sprockets.

If your bike does not currently redline in sixth gear, and still does not after you change the gearing, the top speed will be no different.

The stock chain on the 2001 ZX-6R has size 525. It has 108 links and is made by EK.

Just to fill in a few blanks...
The only time you have to worry about wear caused by a small front sprocket is if you go 13t and smaller. The reason for this is because of the decreased radius the chain has to move through.
It took me about 15 minutes to change the front sprocket, and it's much cheaper. I bought mine at http://www.kneedraggers.com/ and had it in two days.

I stayed stock up front and went with +3 to the rear. I love it, I also can't say I do 150-160 all that often, so losing the top end is fine by me. I put it to where I really can use it.
