transmission gearing in a KFX400 vs Z400

[01 RAPPY 660]

just wondering since Kawasaki and Suzuki use to make the z400 and kfx400 as one,(they seemed to be the same quad). was the transmission gearing any different in the 2 quads? it seams like the Z400 was faster and pulled harder then the KFX400 or did it!?!?!?!?:thinking:

I have never seen the KXF400

But I know that "officialy" suzuki gives the same motors to arctic cat, kawasaki, dezus, etc... as what goes in to every other suzuki...

But there always seems to be less power with the motors that go in to the other brands!

I guess that suzuki is only backing off the size of the cam lobes / timming or maybe just making thicker base gaskets that reduce the compression (without telling anyone)

then there is the issue of the other brands chosing diffrent gearing with the sprockets or making a different air box shape (I think when arcitcat used the LTA500 motor in there atv they make a big stuff up with the airbox and lost heaps of power too)

either way the bike is still going to be a good bike and can always be made to go faster!

i know Suzuki used there Z400 engine in the KFX400 but it seems like the Z400 is faster and has more acceleration.

I have no doubt that it is slower. just because I have seen this before in the LTA500 motor that went in to the arcticat atv and DRZ400 motor in the KLX400R and TL1000R motor in Aprilia road bike, were all a bit slower and less power.

kind of weird i dont see why they did not keep the engines the same? i mean i know Kawasaki and Suzuki split up and went there own ways but back then they were together.

i totaly agree.

But kawasaki and suzuki were only "sharing" some models of each others bikes.

Kawasaki made the new KXF250 2003-2006 (RMZ250 2003-2006)

Suzki inheareted the

KX60

KX110

kawasaki inhearited the

drz125

drz400E

ltz400

There could be more but I cant think off the top of my head.

the only motove suzuki could have is to make their bikes with the same motor "be the best" so that people are more inclined to buy the suzuki bike. and thus make more money?

[01 RAPPY 660]

agreed dude,

money was basically what it was for!

well whatever the case is i have always wondered if one was geared different or had more h.p. then the other
