Sprocket Change

[919Rev]

I am thinking of going -1 +2 on my front and rear sprockets on my 02 ZX9R. I made that same change to my 06 919 when I had it and loved it. Here is the way I look at it:

1. I am an acceleration junkie. That is my hook. I enjoy that part of riding probably more than anything.
2. I will never ride my bike at 170 mph
3. I do mostly short jaunts with very little highway riding so increased rpm at cruising speed isn't a huge thing.

Yes, I realize my speedo will be incorrect and yes I realize as I stated above that my cruising rpm range will be higher, but why not put that power where I can actually enjoy it instead of leaving it unused up top?

Does my reasoning make sense here? After having done the same thing to my 919 I can't think of any other negatives.

Personally, I don't like taking off teeth at the front and prefer to do it all with the rear if possible.
Especially with big power.
A larger front allows a larger radius and more total tooth contact area.

go for it. been wanting to grab a 15 tooth for my 919 for awhile now cus im like you an accel junkie... i dont need to go over 100mph. Never had a problem with dropping one tooth on the front so long as you dont to extreme.

Run a 13tooth on my crf250 and have seen no increase in wear of my new chain. I guess it could be diff with a bigger bike n more powa... but with that becomes bigger and more robust chains.

mcromo44 is right you want the most surface area you can get to hold the chain especially if you do allot of hard acceleration (sounds like you do)
personally i like to take teeth off the rear (I spend allot of time over 100)
keeps the city posers out of my hair
