Kawasaki's site doesn't say.

i would think it would be fairly mild. What does the bike run at? i would guess close or maybe a little less.

Bike is 12.0:1

 

[boosh71]

Since some people actually have a KFX in their garage now, does the manual state the compression ratio?

 

[MileHighRider]

it is 12:1 as quad runner stated

 

[quad_runner]

Same as the KX450F

12.1 is a good number imo, you can run the premium pump gas and still have great power... Now im waiting for a cp 14:1 hahahaha

CP pistons are very nice.

 

[speeddemon619]

im hesitant to run anything but a cp piston. I havent had any issues with cp's but have heard alot of bad stories bout wiseco and je
